Athans A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Department of Counseling and Educational Psychology 1983 ABSTRACT A HOLISTIC APPROACH TO STRESS MANAGEMENT: A PILOT STUDY BY Michael J. Athans This dissertation focused on the holistic variables of nutrition, exercise and coping and defending as a treatment for stress. Thirty-five subjects of this study responded to newspaper and radio public service notices in the greater Lansing area. Subjects were pretested and were randomly assigned to one of two groups. Group One received the five-week workshop based on the holistic model. Group Two was held as a control group and returned six weeks later when all subjects were post- tested. Group Two then received the five-week treatment and was posttested again. The same instructor, nurse, room, time, and day of the week were maintained for consistency of treatment. The workshop (treatment) was focused on stress, its relationship to heart disease, and to psychophysiology. Type A personality was discussed, as well as nutritional, coping, defending, and physical exercise patterns in relation to stress. Subjects participated in a relaxation technique and aerobic exercise. The workshop was didactic and participatory, with small group discussion. Michael J. Athans The dependent variables used during testing periods were the MMPI ego strength and emotional disorder scales, the basic coping and psychogenic attitude scales from Millon's Behavioral Health Inventory, Haan's coping and defending scales, a checklist derived to measure dietary intake and physical exercise patterns, and systolic and diastolic blood pressure readings. In the statistical analysis of data, multiple analysis of covariance was performed on all dependent variables, with sex and pretest covaried. An overall group effect was found to exist, with subsequent univariate analysis revealing the psychogenic attitude scale, Haan's defending scale and dietary intakeanuiphysical exercise patterns accounting for the overall group effect. The results of this study suggest that ego strength and coping styles are less likely to increase as a result of a five-week workshop, whereas subjects' defen- siveness decreased. Blood pressure readings remained normal for both groups during this period. Limitations of this study and recommendations for further research include a larger sample for increased cell size, reducing the possibility of significant results due to chance. Also, a longer period of time may be necessary for physiological and personality variables for change.

People of all ages and occupations use the term "burnout" to describe feelings of physical and emotional depletion. Home situations and personal lifestyles have also contributed to some people's distress, perhaps as a result of a continuously changing, highly technological society. While in 1900 most Americans were farming in rural areas, 75 years later 75 percent had 'crowded into urban areasanuionly 4 percent of the remaining 25 percent were employed on farms. In response to this swift urbanization and change in lifestyles, there has been a tremendous rise in the number of self-help groups, seminars, workshops, and books related to helping people understand their environment and reduce the stress in their lives. Physical stress symptoms range from short-lived fatigue to chronic back pain, migraine headaches and ulcers. Affective symptoms include hostility, aggression, irrita- bility, depression and apathy. Psychosomatic components may comprise or aggravate disorders. For example, Meyer and Haggerty (1962) demonstrated that respiratory illness 1 2 became four times as severe if preceded by acute stress. Doctors trained by the traditional medical model typically pay little attention to personal dynamics such as attitudes, coping and defending behaviors, and nutritional factors such as the excessive intake of sugar, caffeine or meats. The alleviation of immediate symptoms then, rather than the prevention of illness and maintenance of health, has tended to be the focus of traditional medicine. In contrast, the holistic health model has proved useful in preventing stress reactions and alleviating stress symp- toms. Pelletier (1977) states: Holistic medicine recognizes the inextricable inter- action between the person and his psychosocial envi- ronment. Mind and body function as an integrated unit, and health exists when they are in harmony, while illness results when stress and conflict disrupt this process. (p. 11) The holistic model then, holds that each individual is com- prised of a mind, body and spirit interaction and that the body is in a state of health when these elements function in harmony. Disorders are created, not only by physical means, but by the disruptive interaction of social factors, person- ality variables, psychological stress and the inability to find integrative solutions to this complex of variables. Fail- ure to maintain the balance is likely to result in psychoso- matic illness. For example, when a person cannot cope with environmental stress, the body breaks down at its weakest point as part of a disturbed adaptive process. The holistic model suggests that this reaction is not inevitable and that 3 the individual has some control of biological and psycho- logical functions, as well as the environment. Holistic health differs from traditional medicine in that the latter tends to pay less attention to the patient's psychosocial environment and holistic medicine suggests that one can gain control over it by carefully looking at all the factors which may represent potential stressors. Theory From the time of Hippocrates it has been recognized that psychological factors play a precipitating role in physical illness. Ulcers, headaches, asthma and pain are but a few of the ailments thought to be psychogenic in origin. Recent research indicates that certain personality characteristics are more inclined to produce a "stressed state" in the body, thereby making it more prone to such ailments, including coronary heart disease (Rosenman, Braud, Jenkins, Friedman, Straus and Wurm, 1975). Selye's (1956) General Adaptation Syndrome (GAS) is a theory which illustrates the physiological mechanisms in which prolonged stress produces pathology and damage to the body. GAS consists of three states: alarm reaction, stage of resistance.and state of exhaustion. In the GAS, pituitary- adrenal cortical hormone secretions act as a system of defense to ward off noxious stimuli. The alarm reaction is the body's only acknowledgement of stress on the system. In the stage of resistance, the body responds to the stress, increasing its 'resistance to the noxious agent. If these defenses are 4 maintained, disease may result from the adrenal cortical and pituitary hormones, inflammation, and/or the lowering of body resistance, creating an "exhausted" physical state. Numerous studies have shown that how an individual copes may reduce physiological arousal to stressful events (Singer, 1974; Hinkle, 1974). Coping and defending strate- gies, depending on their use, may serve to exacerbate or alleviate the stressful condition. (Mmaexample is the use of repression as a defense, prolonging stress and resulting in increased anxiety or depression. Other mechanisms in the coping and defending processes include denial, tolerance of ambiguity, doubt, empathy, intellectualization, projection, isolation and others. Activity has been known to reduce stress by pro- ducing a healthy, invigorated body (Blumenthal, Williams & ‘Williams, 1980). Increased activity and physical exercise improve the tone and quality of muscle tissue and strengthen the blood vessels, lungs and heart. Even low levels of activity prove more beneficial than none at all. Miller, Rubin, Clark, Crawford and Arthur (1970) found that airplane pilots who were active in the landing of their aircraft had less somatic complaints and less anxiety as compared to :radar intercept officers who have a sedentary role in the landing of aircraft. Holistic medicine emphasizes maintaining a healthy body by exploring one's coping and defending styles and by 5 observingtflmalevel of physical activity and food intake, as this also contributes to how one feels physically. For example, certain foods are easily digested and metabolized. Other foods not only require a longer digestive process, but also release chemicals which must be storedixxtflmabody, at times reaching dangerous levels. One such chemical is tyro- sine, the amino acid found in meat. Julien (1978) believes that it is transformed into amino acids which stimulate the sympathetic nervous system. Such stress on the system may prove harmful over prolonged periods. Proteins, carbohydrates and fats taken in will be reflected in energy levels, as well as in the physical condition of the body. Pritikin (1979) holds that Americans consume an excess of meats at the risk of heart disease. He emphasizes a low fat diet, high in complex carbohydrates to reduce potential for heart disease and reduce lethargy, indicating that nutritional intake plays an important part in whether or not the body feels stressed. The variables of nutrition, physical exercise, and c0p- ing and defending styles as described above, then, are holistic components which act together to determine an indiv- idual's ability to adapt to and deal with stressful encounters in everyday living. 6 Need for the Study A review of the literature suggests that although there are many well thought out theories and re- search studies concerning the relationship between stress and disease, researchers have tended to focus on how stress affects one or another specific area of human functioning. For example, Selye (1956), Levi (1974), and Singer (1974) have emphasized how hormones respond to life adjustments and their effects on the likelihood of disease. Friedman and Rosenman (1974), Dimsdale and Moss (1980), McCranie, Simpson and Stevens (1981) , Howard (1976) , and others have focused on the relationship of Type A behavior patterns to coronary heart disease. Lazarus (1966) has examined how people perceive life events through the appraisal of stimuli. Haan (1963) has looked at c0ping and defending mechanisms, and Hinkle (1974) at how defending relates to frequency of illness. Julien (1978) has studied the intake of foods and how this may create stress a n d Blumenthal, Williams, Kong, Schanberg and Thompson (1980) have done the same regarding the role of physical exercise. There has been little research combining these related theories and studies into an integrated investigation of health. Pelletier (1977) has come closest to this by unify- ing the theories of others into one "holistic" model. How- ever, virtually no research has been undertaken to study these holistic concepts in their mutual interaction as they affect prevention and treatment. Purpose The purpose of the present study is to design a holistic approach to stress management, which includes the variables of nutrition, activityamuipsychological coping and defending mechanisms. The holistic nature of the stress management workshop is emphasized to provide participants of the study with an understanding of how the mind and body work in unison and facilitate coping with stress. Hypotheses The hypotheses of this study are dependent vari- ables measuring the holistic concepts. The dependent variables of coping and defending behaviors are measured using scales from Norma Haan's COping Inventory, the Millon Behavioral Health Inventory and scales from the Minnesota Multiphasic Personality Inventory (MMPI). Nutritional intake and physical exercise variables are measured using a checklist. Physiological readings of blood pressure are recorded as dependent variables. The following are the research hypotheses which are stated in null and research form in Chapter III, and for which the results are stated in Chapter IV. Hypothesis I: The treatment group will show a decrease in posttest scores as compared to the control group on the dependent variable emotional disorder (MMPI). Hypothesis II: The treatment group will have an increase in posttest scores as compared to the control group on the dependent variable ego strength (MMPI). Hypothesis III: Hypothesis IV: Hypothesis V: Hypothesis VI: Hypothesis VII: Hypothesis VIII: Hypothesis IX: Hypothesis X: 8 The treatment group will have a decrease in posttest. scores as compared to the control group on the dependent variable basic coping scales (Millon Behavioral Health Inventory). The treatment group will have a decrease in posttest. scores as compared to the control group on the dependent variable psychogenic attitude scales (Millon Behavioral Health Inventory). The treatment group will have an increase iJ1 posttest. scores as compared to the control group on the dependent variable Haan's coping scales. The treatment group will have a decrease 5J1 posttest. scores as compared to the control group on the dependent variable Haan's defense scales. The treatment group will have a decrease in posttest, scores as compared to the control group on the dependent variable systolic blood pressure. The treatment group will have a decrease 5J1 posttest. scores as compared to the control group on the dependent variable diastolic blood pressure. The treatment group will have improved dietary intake in posttest scores as compared to the control group on the dependent variable nutrition (checklist). The treatment group will exhibit increased physical exercise in posttest. scores as compared to the control group on the dependent variable physical exercise (checklist). Overview The second chapter is a review of the literature pertaining to theory and research leading up to the present study. A basic explanation of stress is from the work of Hans Selye, a pioneer in physiological stress research. The psychophysiology of stress 9 will be discussed to explain the chain of events which takes place from the actual perception of a stressor to its ultimate behavioral manifestation. The pathology of athero- sclerosis, myocardial infarction, and angina pectoris will then be discussed, as these diseases are often manifestationS‘ of advanced forms of stress. Rosenman and Friedman's research on coronary heart disease and Type A personality, and research which supports this view are included. Also important in this section is the role of nutrition and disease, as changes in dietary intake are correlated to such disorders as hypogly- cemia, anxiety, and coronary heart disease. Coping and defending will be examined, as these behaviors play an important role in the manifestation and maintenance of stress. Contributions in this section include the research of Pearlin and Schooler, Norma Haan and Richard Lazarus. A review of pertinent literature indicates that little empirical research has been conducted ontflmzholistic approach to understanding stress. Thus, the last part of the literature review will focus on coping, stress, and the management of stress through holistic methods. The holistic variables of nutrition, physical exercise, and coping mechanisms, which include attitudes about life and work will be discussed. This holistic approach is one method of understanding, treating, and preventing stress. The sample, population, research procedures, hypotheses, instrumentation, analysis and the experimental design of this study are described in Chapter III and Chapter IV is an 10 analysis of data. Chapter V includes a discussion of the results, summary, and conclusions. CHAPTER II REVIEW OF THE LITERATURE Stress Selye (1974) defines stress as "the nonspecific response of the body to any demand made upon it" (p. 14). What Selye means is that itdoes not matter if a situation is pleasant or unpleasant, what matters is how one responds to the situa- tion, since evidence suggests that life events of either a pleasant or unpleasant nature result in increased physio- logical activity. For example, Levi (1964) has shown that both amusing and aggression-provoking films result in in- creased levels of adrenal medullary hormones. While stress has been given "bad press" by a society which finds it all too prevalent, Selye makes it clear that complete freedom from stress could result in death. Exposure of the body to stress may have beneficial or damaging results. Responses to stress are manifested in a variety of ways. When a part of the body is exposed to stress, the result may be increased local resistance, such as adaptation, inflammation or tissue breakdown, depending on the body's interpretation of the need. In response, corticoids will either combat or promote inflammation and hormones will either produce acetylcholine or adrenalin 11 12 for the fight or flight response. Examples of the resis- tance phase at the psychological and physiological levels can be seen in the body's efforts to achieve a homeostatic balance. These include eating when hungry, psychological defense mechanisms, and neural-hormonal reactions to stress on the body. The Psychophysiology of Stress Attitudes contribute to how we feel because they are perceptions which are learned over time and include feelings and beliefs about other persons, objects, events, and activities (Tossi, 1977). Once the above stimuli are per- ceived as stressful, the body then produces a neurophysio- logical reaction which stresses the body and can cause permanent harm if prolonged (Selye, 1974). An example is frustration, which may turn stress into distress. Selye's (1956) "General Adaptation Syndrome" (GAS) explains three phases which are constantly reproduced when demands are made on the body. The first phase is an alarm reaction which results from dealing with a new or ambiguous situation. ffluaphysiology of this reaction involves increasing sympathetic-adrenomedullary activity by sending epinephrine through the vascular system. The second phase of this syndrome is the resistance state, in which the body attempts to make a physiological adjustment. Adaptation 13 during the resistance phase takes place if one learns to cope with the stimulus. Exhaustion is the final state of the adaptation syndrome, occurring after prolonged exposure to a stressor, when energy resources become depleted. Death is the body's most dramatic response to prolonged stress. To explain how these reactions come about, it is neces- sary to know that the nervous system is broken down into a central nervous system (CNS) and a peripheral nervous system. The CNS consists of the brain and the spinal cord, the peripheral system contains all the neural tissue outside the CNS (see chart 1). The peripheral nervous system is further described as having somatic and autonomic components, with sympathetic and parasympathetic systems forming part of the autonomic nerves and muscle tissue. Both the brain and the autonomic system are important in that the brain perceives stressful stimuli and regulates bodily functions, and the autonomic system responds to these signals viscerally through neural tissue. The subcortical areas of the brain regulate normal body functions and include the basic control center for the auto- nomic nervous system, which is the system principally respon- sible for maintaining a stressed state. This area includes the cerebellum, the center regulating body movements; the medulla oblongata, which regulates heartbeat, respiration, and blood vessel diameters; and the pons, which regulates the sleep cycle. l4 oeumnummEMmmnmm xmpuooooz anocous< oeumnummESm Emummm . mso>umz vaumeom Hmumnmwnom ouoo Hmcflmm mummcoHno waacomz rrn mcom :flmunocflm a O M .u Enaamnmumo mm Rfir Em m» msEmamsuommm camum msowumm coamnmmocwwo .

The hypothalamus is also connected with the limbic system, and is known as the seat of emotion. Chauchard (1962) and Gelhorn and Loufbourrow (1963) consider the hypothalamus a critical organ in the regulation of emotion. Stress activates the autonomic nervous system and the endocrine system through the limbic system, which determines when the hypothalamus will be activated. This organ also responds to perceived stress from the cortex, which is responsible for the higher-order abstract functions of language, memory, and reasoning. The brain stem reticular formation is part of the CNS. It extends up the rear of the medulla into the midbrain and the hypothalamic part of the forebrain. The reticular forma- tion, also known as the reticular activating System (RAS), is discussed because it serves as a general arousal system, activating the cortex to stimulate visceral arousal and muscle tension (French, 1957). The end result, not produced by the reticular system alone, is the changing of a psychological stressor into a neurophysiological response where the subjective experience of stress is also felt physically. The autonomic nervous system controls gastrointestinal, vascular, and reproductive functions. The sympathetic nervous 16 system, a part of the autonomic system, serves to control involuntary muscles and constrict blood vessels. The para- sympathetic system acts to extend smooth muscles, thereby inducing relaxation. When a stressor is perceived by the cortex the brain sends signals out so quickly that the auto- nomic system is said to react "automatically," exciting or inhibiting the sympathetic or parasympathetic systems through muscle extension or contraction and blood vessel constriction or dilation. When the sympathetic system constricts blood vessels to accelerate heart rate, blood moves away from the body's extremities to the head and trunk, resulting in the feeling of cold hands and feet. Muscle tension is also perceived under stress; even if not consciously recognized, it can leave the body drained at the end of a day. The sympathetic and parasympathetic systems of the auto- nomic nervous system are receiving increased attention because evidence indicates that it is possible to gain some control over these systems. Meditation, biofeedback, and other relaxation techniques are relatively recent methods of reducing muscle tension and hormones in the body. When a stressor is perceived it also excites the hypothala- mus, which in turn produces a substance that stimulates the pituitary. This gland is part of the endocrine system which secretes the adrenocorticotropic (ACTH) hormone into the blood, maintaining a stress reaction by stimulating the heart and brain for the fight or flight response. Recent evidence indicates that under long—term stress, ACTH induces the external cortical portion 17 of the adrenal gland to secrete corticoids which act to inhibit inflammation and defend the body via immune reactions. Thy- roxine is also produced during periods of long-term stress, while adrenalin is activated by the adrenal gland to deal with short-term stress, dilating the arteries of the heart, ‘ accelerating heart rate, and increasing blood circulation (Selye, 1954; Pelletier, 1977; Jenkins, 1978). Simpson, Olewine, Jenkins (1974) and others find that under stress there is increased tendency for the clotting elements of the blood to build up plaque and thicken the arterial wall, narrowing that passageway. As blood vessels narrow and clots form, there is greater likelihood that the clots will occlude a coronary artery, resulting in angina pectoris or myocardial infarction. Singer's (1974) research also shows that intense day-to-day involvement is linked to elevated blood pressure and increased endocrine response. Stress and Disease Some diseases in which stress plays a particularly important role are high blood pressure, atherosclerosis, myocardial infarction, angina pectoris, gastric ulcers, and various mental disturbances. Atherosclerosis is a cardio- vascular disease, the most prevalent disease of mankind. In 1978 there were two million deaths in the United States, of which 52 percent were due to cardiovascular disease, mainly the result of atherosclerosis. Myocardial infarction is a dramatic form of heart disease in which 95 percent of the victims suffer from atherosclerosis. One of the causes of 18 this condition is a lesion or obstruction in the arterial wall,vflfixfileventually produces a heart attack. Where occlusion is not evident, any sudden increases in myocardial demands, including those produced by physical or emotional stress, may lead to myocardial infarction. The personality variables such as hard striving for achievement which contribute to a stressful lifestyle, lack of regular physical exercise and high intake of saturated fats are said to be predisposing factors for heart disease. Other predisposing epidemiological factors include: elevated lipoprotein (this includes cholesterol), increased blood pressure, cigarette smoking, and elevated blood sugar (Robbins & Angell, 1976). Evidence suggests that anxiety, depression and psycho- somatic illnesses are also related to the develOpment of coronary heart disease, particularly angina pectoris. The attacks are thought to be caused by a sudden inbalance between myocardial demands and the capacity of the coronary arteries to fulfill those demands. Angina is defined as chest pain precipitated by effort and alleviated by rest. Ostfeld, Lebovits, Shekelle and Paul (1964) found that people who developed angina complained of a variety of somatic symptoms. Repression and denial were often used by these patients in an attempt to resolve emotional conflicts and dissatisfaction. In the above study, men who subsequently developed angina pectoris, as compared to myocardial infarc- tion patients and those without heart disease, scored 19 significantly higher on the MMPI Hypochondriasis and Hysteria scales and lower on "dissatisfied emotionally" scale of the 16PF, two personality inventories which measure psychological traits. The role of anxiety in coronary heart disease was also discussed by Medalie, Kahn, Neufeld, Riss, Goldbourt, Perlstein and Oron (1973), who foundtflmn:subjects who scored high in anxiety were twice as likely to develOp angina pectoris as those who scored low on anxiety. The research of Medalie et a1 supports Jenkin's (1971) statement that work overload and chronic conflict situations may be precursors of coronary heart disease. PeOple with problems related to family, work, and finances were found to be more likely to develop angina pectoris than those without such conflicts. Starting in 1960, Rosenman,Friedman and their colleagues followed 3,500 men for eight and a half years in a longitudi- nal study known as the Western Collaborative Group Study (WCGS). The men were examined medically, and the results of the examination indicated that men of average height who developed coronary heart disease were similar to healthy men, but heavier in weight. In addition, men who reported moderate to heavy work activity, or who undertook regular daily exer- cise had lower rates of heart disease than those with sedentary to light work and virtually no exercise. Cigarette smoking was found to be a significant precursor of heart disease among men 39 to 49 years old, but not for men in the 50 to 59 age bracket (Rosenman, Friedman, Straus, Wurm, 20 Kositchek, Hahn, and Werthessen, 1964). A history of coronary heart disease in either parent was also associated with a higher rate of coronary heart disease. Biological factors found to be significantly related to heart disease in the Rosenman study included systolic and diastolic blood pressure, as well as serum concentrations of cholesterol, triglycerides, lipalbumin, beta lipoproteins, and the beta/alpha lipoprotein ratio. At both high and low cholesterol levels, men with high beta/alpha ratios developed more coronary heart disease than those with lower ratios. Heart Disease and the Type A Behavior Pattern The results of the Rosenman and Friedman study also confirmed the Type A behavior pattern as a precursor of chronic heart disease, independent of the standard risk factors (Rosenman et al., 1975; 1964). Subjects in their study were classified as either "Type A" or "Type B" person- alities, following a structured interview. Type A person- ality exhibits behavior characterized by hard driving, aggres- sive striving for achievement, competitiveness, impatience, restlessness, a continual state of alertness, and consistently hurried activity (Jenkins, 1971). Type B personality lacks these characteristics. In the WCGS longitudinal study, those subjects judged to be Type A at the onset of the study exhibited twice the rate of coronary disease, were five times as likely to have a second myocardial infarction, and had twice the rate of 21 fatal heart attacks as those who did not exhibit Type A characteristics (Type B subjects). These differences remained, even when serum lipids, blood pressure, smoking, obesity and other biological factors were held constant statistically. The risk was, in fact, approximately equal to that produced by other chronic heart disease risk factors such as elevated blood pressure, high cholesterol levels, or cigarette smoking. Similar findings have subsequently been reported by Kenigsberg, Zyzanski, Jenkins, and Warwell (1974). Other researchers have independently reported empirical evidence from studies of coronary heart disease patients and matched control groups, indicating that patients with coronary disease strive more diligently for achievement, tend to be perfectionists, are chronically tense and unable to relax, are committed to expending more energy on a job or profession, and are more active and energetic than corresponding compari- son groups (Jenkins, 1971). This constellation of traits approximates RosenmananuiFriedman's Type A behavior pattern, which also includes aggressiveness and time urgency among its essential aspects (Rosenman et al., 1964; Friedman, 1969). Howard, Cunningham, and Rechnitzer (1976) conducted a study similar to Rosenman and Friedman's, in which 236 managers from twelve different companies were examined for prevalence of Type A behavior. This three-year longitudinal study included a number of measures of health, job and career 22 issues, personality, changes in lifestyle and family environment. Physiological measures included resting blood pressure, serum, lipids, and an exercise stress test. Approximately 60 percent of the managers were classified as Type A‘s. The result showed that lower levels of education were associated with a greater prevalence of Type A behavior. Type A behavior also declined slightly with age, while Type B behavior increased slightly with age. In the biochemical analyses, Type A persons exhibited significantly higher systolic and diastolic blood pressure and serum triglyceride levels than Type B individuals. Subjects were also asked to indicate their exercise and smoking habits. Although a large percentage of Type A's were found to be cigarette smokers, smoking was not found to be significantly related to either behavior type. In contrast, however, exercise habits were type-related; in every age group except the eldest, a larger percentage of the Type B's were exercisers. The above results tend to confirm the findings of Rosenman and Friedman and indicate how the Type A behavior pattern is related to a number of the risk factors in coronary heart disease. Jenkins (1978) went further to suggest that the Type A behavior pattern is specifically associated with atherosclero- tic diseases. Analysis of the Western Collaborative Group Study shows that only those persons dying of coronary disease and those dying of accidents clearly have a Type A mean score on the Activity Survey, a measure of Type A personality. Jenkins reports that men dying of malignancies, lung diseases, 23 and the like tend to be rather evenly distributed between Type A and B, often closer to Type B. Blumenthal, Williams, Kong, Shamberg and Thompson (1978) found similar results in that the Type A behavior pattern was not only associated with increased risk of specific coronary heart disease events, but was even more prevalent among patient groups with more severe coronary atherosclero- sis. The findings further suggest that behavior patterns are related to atherosclerotic processes in women as well as men. Their 156 patients received a behavioral evaluation (using the structured interview technique develOped by Rosenman and Friedman), psychological testing, blood levels, and arterio- grams. A medical history was taken prior to coronary angio- graphy. The authors found Type A behavior patterns to be related to indices of lipid metabolism previously associated with increased risk for coronary heart disease. The Type B patients had a mean serum cholesterol level of 211 mg, with Type A having 248 mg. This difference was statistically significant and remained so when means were adjusted for age and sex. Type A behavior patterns were also related to a positive history of hyperlipidemia. Blumenthal and his associates did not find statistically significant differences between Type A and Type B patients with respect to cigarette smoking or blood pressure. However, the relationship between behavior pattern and total coronary index remained signifi- cant when age, sex, blood pressure, cholesterol, and cigarette smoking were all simultaneously covaried. 24 The Rosenman and Friedman research, and the research it stimulated, raise the question of eventual, personal control over chronic heart disease. The findings have many implications which could conceivably reduce the incidence of heart disease and its annual cost. The evidence that Type A behavior may even play a role in the atherosclerotic process suggests that the pattern exerts its influence upon chronic heart disease risk over time and highlights the importance of identifying and modifying Type A behavior patterns early in life. Nutrition and Disease There have been many changes in food consumption in the United States in the last few years, with dramatic increases in carbohydrate and sugar consumption and a reduction in the use of protein. Malnutrition is a word that is no longer associated with only underdeveloped countries: The nature of the aberration is (1) an excess of total calories, empty calories,total fat, saturated fat, cholesterol, refined sugar, salt, and (2) an inadequacy (relative and/or absolute) of essential nutrients (vitamins, minerals, essential amino acids and essential fatty acids) and bulk. This malnutri- tion of a different type is actually widespread in the economically developed countries--malnutrition in the literal meaning of the word, bad nutrition. (Katz, Stampler and Pick, 1958) A change in the pattern of carbohydrate intake appears to be the most obvious alteration in the world's dietary intake during the twentieth century. This pattern essentially involves a reduction in complex and an increase in simple carbohydrate consumption (Albrink, 1965; Antar, Ohlson and 25 Hodges, 1964; Takahashi, 1962; Yudkin, 1964). Such eating habits tend to reduce the intake of protein, vitamins, and minerals since many of the simple carbohydrate foods are relatively low in these nutrients. In this regard, an association is thought to exist between abnormal behavior and the metabolism of nutrients. Specifically, carbohydrate metabolism is correlated to disorders. One of these, hypoglycemia, is an excess of sugar or glucose in the blood as a result of diet and has been observed to mimic many psychiatric, somatic, and neurological disorders. Correlations exist between hypo- glycemia and anxiety, irritability, fatigue, mental confu- sion, and uncontrollable emotional outbursts (Richter, 1959; Williams, 1959; Salzer, 1966). (See Table 1). Depression has been linked with dietary riboflavin or pantothenic acid deficiencies (Eiduson, Geller, Yuwiler and Eiduson, 1964). Diet deserves serious attention in the coronary proneness profile because of its effects on nutritional, endocrinologic and metabolic status. The dietary alterations suggested by the Council on Foods and Nutrition are primarily concerned with the regulation of dietary fat, especially the saturated 26 TABLE 1 MAJOR SYMPTOMS IN 300 CASES OF RELATIVE HYPOGLYCEMIA Percentage of Patients Symptoms Reporting Symptoms Psychiatric depression 60 insomnia 50 anxiety 50 irritability 45 crying spells 32 phobias 31 lack of concentration 30 forgetfulness or confusion 26 unsocial or antisocial behavior 22 restlessness 20 previous psychosis 12 suicidal 10 Somatic exhaustion or fatigue 87 sweating 41 tachycardia 37 anorexia 32 ‘ chronic indigestion or bloating 29 cold hands or feet 26 joint pains 23 obesity 19 abdominal spasm 16 Neurologic headache 45 tremor (inward or external) 42 muscle pains and backache 38 numbness 29 blurred vision 24 muscular twitching or cramps 23 staggering 18 fainting or blackouts 14 convulsions 4 SOURCE: H.

Concern with substantial increases in simple carbohydrates in economically advanced countries in the twentieth century, and a closer relationship between ischemic heart disease mortality and sugar intake is more recently apparent. Significant blood glucose changes follow the elimination of refined carbohy- drates from the diet. There is a direct relationship between glucose in the blood and systolic blood pressure; as glucose levels increase,so does systolic pressure. The reverse is also true. While these relationships (see Tables 2, 3) have been well established, blood glucose levels will vary and researchers have not yet determined what levels are physio- logically acceptable to avoid coronary heart disease and possible early death (Antar, 1964; Greaves, 1964; Yudkin, 1964; Ashton, 1965; BanyOpadhyay, 1964; Yudkin, 1966). The data suggest the need for further research in the area of dietary carbohydrates and coronary heart disease. Field Dependence and Independence Extensive research indicates that field dependent and field independent individuals differ in aspects of social behavior and physiological functioning. Field dependence is the extent to which individuals utilize external frames cf reference in organizing their perceptions. Field depen- dent individuals exhibit a reduced sense of separate identity from other peOple, reflected in such traits as preferring more social interaction with others, being more attentive 28 TABLE 2 INTERRELATIONSHIPS BETWEEN DIETARY CARBOHYDRATE, BIOCHEMICAL PARAMETERS OF ENERGY METABOLISM, AND DISEASE STATES Diet Metabolism Disease State High carbohydrate intake Increases serum tri- glycerides, circula- tion insulin and insu- lin resistance Enhances atherosclerosis and the development of diabetes mellitus High refined carbo- hydrate intake Results in a deficiency of specific carbohydrate enzymes and a decrease in glucose tolerance Gives rise to diabetes mellitus and athero- sclerosis Most of dietary carbohydrate as sucrose or glucose Causes an increase in serum triglycerides A feature of: obesity, diabetes mellitus, gout, atherosclerosis Most of dietary carbohydrate as starch Produces a reduction in serum triglycerides 100 gram glucose tolerance supple- ment of 60 grams intravenously Produces an excessive serum insulin response Obesity, hyperglyceri- demia 100 gram oral or 25 gram intravenous glucose tolerance supplement Yields evidence of a close association between impaired glu- cose tolerance and increased serum tri— glycerides Supports the possibility that elevation of plasma triglycerides is a mani- festation of insulin re- sistance and represents a stage in the development of maturity onset diabetes SOURCE: M.

A number of studies have found field dependent individu- als to be more likely to have higher basal levels of galvanic skin reponse (Silverman, Cohen, Shmauonian, & Greenberg, 1961), higher levels of free fatty acids (McGough, Silverman, & Boddonoff, 1971), and higher levels ofserum cholesterol (Flemenbaum, 1978; Sousa-Poza, Rohrberg, Bellabarba & Ruest, 1976) in comparison to more independent persons. Several investigators have interpreted these findings to indicate a heightened state of autonomic arousal in field dependent individuals as compared to their field independent counter- parts (Flemembaum, 1978; McGough, Silverman, & Boddonoff, 1965; Pillsburgy, Meyerowitz, Salzman, & Satran, 1967; Silver- man, McGough, & Boddonoff, 1967). These physiological find- ings suggest that degree of field dependence/independence may be an important personality dimension influencing Type A individuals, as well as others. Compared to field independent Type A individuals, field dependent Type A's may be expected to experience greater auto- nomic arousal in response to environmental stimuli. McCranie, Simpson, and Stevens (1981) hypothesized that persons posses- sing a field dependent cognitive style in combination with Type A behavior would exhibit higher levels of serum choles- terol and triglycerides than field independent Type A individu- als. In a study of 82 medical students, these researchers' results showed that field dependent Type A's had higher total cholesterol and triglyceride levels than field independent 31 Type A's and either group of Type B subjects. They suggest that field dependent Type A individuals become more physiologi- cally aroused in response to environmental stimuli due to self-involvement and awareness, leading to greater physio- logic motivation in response to perceived environmental challenges.» They further believe that these individuals are more concerned with comparing and evaluating their behavior and performance with that of others, thereby producing chronic arousal in response to perceived inter- personal challenges. Field dependence/independence research confirms that when social, environmental, and physiological factors impinge upon individuals, they affect psychological states and are perceived as stressful. Psychodynamically, the above research may be interpreted to mean that a combination of Type A behavior and a field dependent cognitive style reflects chronic tension. Despite the fact that these individuals describe themselves as having Type A traits, they also exhibited a cognitive style associated with reduced orienta- tion toward autonomous achievement striving and a greater need for the external guidance, perhaps in an attempt to deny or repress their underlying passive, dependent tenden- cies. Such considerations become important in examining coping and defending styles and their impact on stress. Coping and Defending A careful look at coping and defense mechanisms is needed because people use coping and defending styles to perceive and 32 react to the world emotionally. This has been found to affect their physical health, as evidenced by the psycho- physiology literature. Pearlin and Schooler (1978) gathered information about coping responses and psychological attitudes through sched- uled interviews with a sample of 2,300 subjects representa- tive of the Chicago area census. The final sample had an equal number of males and females, and an age group ranging from 18 to 65 years of age was used in order to employ subjects at various stages of their careers. The interviews yielded three distinct types of information about (1) poten- tial life strains such as conflicts and frustrations, (2) coping responses employed to deal with stressors, and (3) perceived emotional stresses. Using factor analysis, major themes were identified from listed stressors, including three involving marriage, three involving parenting, and four involving occupations. The researchers defined psychological resources as those parts of personality that help individuals withstand threats in their environment. Such psychological resources define how people function. C0ping responses are different than psychological resources in that they comprise what people do to deal with environmental stressors. (In the study, the authors identified three relevant c0ping responses. The first, changing the stressful situation, is the most effec- tive way of dealing with stressors, as it acts to eliminate the cause of stress. Although such a response appears 33 obvious, it was used quite infrequently by study subjects, either because the situation was not recognized as a problem or because subjects lacked the ability or knowledge to change environmental circumstances; some attempted to change their situation by substituting one stressor for another. A second coping response, in which coping does not succeed in changing the situation, is altering the meaning of the problem through rationalizing, selectively ignoring or making the situation less important, and substituting other rewards. The third type of c0ping function manages stress attitudinally. Examples here are beliefs that "time will change everything," "everything works out for the best," and similar reassurances. Pearlin and Schooler found that occupationally, the most effective way of coping involves the manipulation of goals and values. People unable to control stress in their occupations will devalue the importance of their work, with- drawing psychologically from that environment. Such devalua- tion and withdrawal differed from the techniques found to be effective in the areas of marriage, parenting, and household economics, where mastery and positive self-esteem were important means of c0ping. In all areas, stress was found to be the result of self-denigration more than any other personality factor. Individuals' attitudes about their work environment were also found to be important factors in creating possible stress. 34 In order to determine which is more efficacious, person- ality characteristics (including psychological resources such as self-denigration, mastery, and self-esteem) or specific behavioral responses to specific role situations, Pearlin and Schooler put summary scores in a regression analysis. The results indicated that occupational stress management is more amenable to the psychological resources of the person than to specific coping responses. The results also indicated that while psychological characteristics are important in dealing with environmental stressors at work, what one does matters more in interpersonal relationships. The authors suggest that future studies should look not only at what peeple do for c0ping efficacy but the situations in which they do it as well, for c0ping mechanisms vary in different role situations. Freud, as early as 1911, recognized that people respond to threat by defending against it, in order to protect the sphere of the ego. His theory on ego functioning and the use of defenses has since been expanded upon by Anna Freud (1936) and many others. Freud used the terms "conscious" and "ego" interchangeably. The ego develOps as the organism changes from primary process, which is the infant's need for immediate gratification, to secondary process, where thought, perception, memory, language, and delay are incorporated into the structures of the young child through the normal process of growth and development. The ego, in incorporating these functions, acts to mediate the perception and comprehension 35 of external and internal stimuli. It responds to anxiety and conflict by employing countercathartic energy to keep these stressful stimuli out of consciousness through the use of defenses. The ego, then, can be seen as a mediator of the external world and its demands, and its internal frame of reference. Defenses are used in this capacity to lessen the discrepancy between these two realities (Blank & Blank, 1974). Conflict, anxiety, and their defenses are often resolved through repression but may reproduce the stress in the dis- guised form of a symptom (Blank & Blank, 1974). Continued use of defenses suggests a stressed state in the individual with psychosomatic illness or conversion reactions, possible long-term side effects. Lazarus (1966), although not a psychoanalyst, incorpor- ates the roles of the ego and perceived threat to the system in his theory. He defines psychological stress as a result of cagnitive appraisal of the threat, which must be antici- pated or future-oriented, and result from the processes of perception, learning, memory, judgment or inference, in which data are assimilated to assume ideals and expectations. Ambiguous stimuli require the processing of belief systems about the organism and its environment. Personality variables such as trait anxiety and self-esteem come into play here, in that they affect the appraisal of the threat. The level of anxiety experienced and one's self—esteem contribute to the appraisal of threat. A person with high self-esteem who is not experiencing anxiety will perceive stress as less 36 threatening to the system than a person with low self-esteem who is experiencing anxiety. Anticipation of stress is best explained by the Shannon, Szmyd and Prigmore (1962) study, which showed that anticipa- tion of dental procedures resulted in marked adrenal cortex stress responses. This finding further solidifies our concept that the anticipation of oral surgery stimulates the adrenal cortex. It was further evident that in groups of patients scheduled for different oral surgical pro- cedures, higher steroid concentrations were present in those subjects scheduled for more complicated operations. Since the pituitary—adrenal system is generally stimulated under conditions in which the integrity of the organism is threatened, it might be expected that fear or anxiety most likely would be associated with increased ACTH release and subsequent increased secretion of adrenocortical hormones. The increased pre-Operative steroid levels are thus held to be the result of 'psychological stresses' incident to the anticipation of undergoing oral surgery. (p. 3) It is evident that once a stimulus has been perceived as threatening, c0ping mechanisms act to deal with the stress. COping is based on cognitive activity involving appraisal of the conditions of threat which will result in the coping response. Lazarus defines defense as a part of the c0ping process in which individuals psychologically deceive them- selves about the actual conditionscfifthreat. Defenses act to distort the threatening experience so that it appears less dangerous to the organism. Lazarus thus views c0ping and defending as one process. Coping is not a threat, but an appraisal of the situation. When necessary, the individual responds defensively for experiences to appear less threatening. 37 If a person does not perceive that danger exists, then no stress reaction will be evident. Hinkle (1974) analyzed the personality factors distinguishing peOple who were rare- ly ill from those with frequent illnesses. He suggests that those who remain healthy show a lack of concern for other pe0ple and life goals, and lack of involvement in life affairs. The healthiest members of our samples often showed little psychological reaction to events and situations which caused profound reactions in other members of the groups. The loss of a husband or wife or a failure to attain apparently important goals produced no profound attachment to people, goals or groups. . . [they] behaved as if their own well being were one of their primary concerns. An employed man or woman might refuse a promotion because he, [or she] did not want the increased responsibility, refuse a transfer because it was too much trouble. . . . As family members, such people might refuse to take the respon- sibility for an aged or ill parent or sibling, giving as an explanation a statement implying that it would be "too much for me." (pp. 40-41) These individuals appear to be using their defenses to protect themselves from threatening life experiences. If no appraisal ofstress is made, then coping and the physiological responses to the threat will not occur. If the stress is appraised, however, then c0ping strategies and physiological mechanisms come into play. Haan (1977) reinterprets and adds to the psychoanalytic theory of the ego's efforts to modify conflict through its defensive role. For example, psychoanalysts recognize the adaptive defenses of sublimation and substitution as a healthy means of gratifying primitive impulses. Haan defines these healthy adaptations and others as c0ping. She views coping mechanisms as consistent with healthy ego functioning. 38 whereas defenses are perceived as a threat to the ego. Haan also differs from Lazarus in believing that c0ping and defending are on a continuum and use similar mental processes. She lists a variety of ego mechanisms with defensive and c0ping modes (as well as a "fragmented" mode). The c0ping modes include objectivity, intellectuality, logical analysis, tolerance of ambiguity, empathy, regression in the service of the ego, concentration, sublimation, substitution and suppres- sion. The defensive mechanisms of the ego which serve to dis- tort reality are isolation, intellectualization, rationaliza- tion, doubt, projection, repression, denial, displacement, reaction formation and regression. An example of the con- tinuum may be represented by the coping mode of objectivity, which enables one to separate ideas from feelings to achieve objective evaluations, versus its defensive counterpart, isolation. When isolation is used as a defense, the subject is unable to integrate ideas and the affect does not appear related to ideas. Similarly, intellectuality is the ability to detach oneself in an affect-laden situation which requires impartial analysis. This ceping mechanism's defensive counter- part is intellectualization, which involves the use of words and abstractions to retreat from affect. Coping, then, involves purpose and choice and enhances appropriate expres- sion of affect. Defenses are more rigid, distorting and negating appropriate affective expression. Haan groups psychological reactions to stress by whether they are assimilated or accommodated by the ego. The 39 Piagetian technique of assimilation is employed when an organism utilizes something from its environment and incor- porates it. Accommodation results when the ego structure is changed by the input. Assimilation responses are the result of: 1. not anticipating the stressful event, 2. differential expectations, 3. ambiguous situations, 4. individuals believing they will be stressed, 5. a situation thought to be similar to one previously not handled well, 6. an individual being in a depleted state when the stress occurs, 7. lack of information necessary to process the situation. Accommodation is the result of: 1. inability to control the stress, 2. prolonged stress, 3. intense stress, 4. continual exposure to varied stresses, 5. little previous experience in dealing with stress. These responses arise because peOple have different c0ping responses as a result of varied childhood ego development, differential interpretations of situations (cognitive processing may trigger different associations or emotions), and because some have more support systems than others. For Haan, then, intervention should focus on coping mechanisms and concommitant affect (Haan, 1977). 40 Empirical evidence supports the proposition that in- creases in defensive behavior are related to threat and stress reactions (Fenz & Epstein, 1962). Lazarus and others (1962) showed that when denial and intellectualization were used defensively, subjects showed lower levels of stress response, including autonomic levels of arousal. These data support the contention that the way in which a person appraises and copes with an environmental stressor has an important bearing on the emotional and adaptational outcome and further indicate that defensive functioning is success- ful in a variety of stressful situations. For example, a seriously ill patient who denies or ignores a diagnosis and is not willing to accept the possibility of death, may fare better psychologically and physically than one who accepts and succumbs (Gentry, Foster & Harvey, 1972). Carl Rogers also has acknowledged that a closed, well-defended person is likely to c0pe with stress better than his ideal of the Open, sensitive person (see Bergin & Strupp, 1972, p. 316). Hormonal secretions also appear to be related to the success of c0ping mechanisms. Friedman, Mason and Hamburg (1963) studied parents whose children had incurable cancer. Two defensive subjects (one father and one mother) living on the ward and two defensive subjects living at home were compared to a group of parents whose children were hospi- talized for cancer. The parents were observed and their urine specimens taken frequently during the children's hospitalization. Although there were noticeable increases 41 in threatening events, urinary excretion of hydrocortizone remained remarkably stable during the period. Friedman et al. suggest that levels of hormonal secretion seemed to be dependent on the success of the parent's defensive (coping) ability. Thus, hormonal stress reactions are not increased when psychological defenses serve to protect the individual from environmental stress. Holistic Theory Rogers (1960) discusses the rationale behind holistic theory which holds illness to be a complex concept that incorporates multiple physical and emotional stresses. There is growing suspicion that many a focus of pathology heretofore considered as the specific consequence of a specific cause may not be so at all. . . . Thus, we are led to the concept of multiple causation of illness. This concept main- tains that illness is rarely the result of the impact of a single, discrete, disease-causing agent (such as the tubercle bacillus) upon an otherwise normal and healthy man. Rather, it holds that most, if not all, illness is an expression of a basic unbalance in man's physiological adaptation to multiple physical and emotional stresses that are initiated, for the most part, in the condition of his external environment. Thus, how individuals perceive and evaluate information from their environment influences thought processes, diet, and muscular activity. Attitudes also play a part because they reflect an individual's feelings and beliefs about other persons, objects, events and activities, and are developed over time, as are diet, the use of physical exercise, and the ability to relax (Girdano, 1979). Certain attitudes influence life styles which may contribute to the development 42 of disease (Friedman & Rosenman, 1974). The holistic approach to stress takes into account life styles and attitudes about living, including attitudes about diet and physical exercise, as well as methods of coping and attaining psychological well- being. All of these contribute to perceptions of stress and its management. Nutrition Nutrition is the relationship of foods to the health of the human body, and prOper nutrition is defined as the intake of an adequate balance of all the essential nutrients in order to promote health. It has long been established that an improperly balanced diet will lead to nutritional deficien- cies, with resultant ailments. Fats, carbohydrates and proteins, for example, are essential sources of energy. Failure to ingest proper amounts of these nutrients will result in stressanuipossible death. Good quality diets, then, which are relatively high in protein and vitamin components are in harmony with optimal health. The converse parallels an increased incidence and severity of disease. Today germs are not our principal enemy. Our chief medical adversary is what I consider a disturbance of the inner balance of the constituents of our tissues, which are built from and maintained by necessary chemicals in the air we breathe, the water we drink and the food we eat. For a generation we have worked on the concept that our cells are never static and that in time must be replaced in varying degrees by the nutrients obtained from food. More specifically, our working hypothesis has been that all disease is chemical and when we know enough, chemically correctable. (Spies, 1958, p. 675) 43 Turning from the essential components of food necessary to maintain health, there are others that represent a hazard to healthy functioning. Caffeine is an ingredient found in coffee, tea, cola and chocolate. The use of caffeine raises nutritional concerns because of its pharmacological actions. This popularly consumed drug stimulates the central nervous system, heart, kidneys, lungs and arteries, as it is totally absorbed into the blood stream and carried throughout the body and brain. With 100 to 200 mg of caffeine (the equiva- lent of one to two cups of coffee), the brain easily becomes stimulated. The spinal cord is the next target for larger doses. Although behavioral signs suggest increased mental alertness due to an increase of blood pumped to the heart, caffeine actually decreases blood flow to the brain by constricting the cerebral blood vessels (Julien, 1978), with the end result being more work for the heart, thereby creating more stress. Evidence also indicates potentially deleterious effects of caffeine stimulation at the fetal level of development (Goldstein, Aaronow & Kalmen, 1968). Nicotine is also a widely used psychoactive agent that stimulates the central nervous system and cerebral cortex, producing increased levels of anxiety. Nicotine, like caffeine, acts to stimulate the brain but is actually a long term depressant of the nervous system. Normal use of nico- tine also increases heart rate and blood pressure, acting to stimulate the heart, increase its work load and create more stress. Other effects of smoking include strain on the 44 vascular system, the formation of blood clots, chronic toxicity, and a positive correlation with lung cancer (Julien, 1978). The intake of meat may also have deleterious effects on the body. It is controversial at this time whether exces- sive consumption of meat, as a form of protein, serves to overstimulate the sympathetic nervous system. The amino acid found in meat, tyrosine, is transformed into Depa, dopamine, and norepinephrine. Julien (1978) suggests that neurons containing these transformed amino acids (mainly norepinephrine) are associated with arousal reactions. He believes that norepinephrine acts to trigger the sympathetic nervous system, which releases epinephrine and creates intense emotional experiences in the peripheral nervous system. His theory suggests that excessive meat intake creates an imbalance in the biological system, not unlike those which occur during particularly stressful periods. For example, Dimsdale and Moss (1980) studied plasma catecholamine levels obtained during the initial moments of public speaking. The researchers found that both norepinephrine and epinephrine increased significantly at these times. The increase of epinephrine was particularly striking, in effect serving to keep the speaker in a ”stressed" state. These chemical effects appear to be similar to those subsequent to excessive meat consumption.‘ The effects of excessive sugar intake and resulting hypoglycemia on the body have already been discussed as a 45 cause of high blood pressure and ischemic heart disease. This simple carbohydrate and its increased consumption is noteworthy because of its deleterious effects on the system. The relationship of diet to disease is based on the notion that health and sickness are the result of many inter- acting factors. When a host succumbs to one or more of the many environmental influences, low resistance or high suscep- tibility to disease is likely. Diet can serve in various ways to modify the host state so that nutrients may increase resistance. Conversely, the lack of nutrients can serve to decrease resistance and exaggerate susceptibility to disease. Physical Exercise A healthy body is the result of prOper nutrition com- bined with a regular program of exercise. Exercise improves the tone and quality of muscle tissue and stimulates the processes of digestion, absorption, metabolism and elimina- tion. It also strengthens blood vessels, lungs, and heart, resulting in improved transfer of oxygen to the cells and increased circulation to the blood and lymph systems. Blumenthal et al. (1980) found evidence that a supervised program of regular exercise can successfully modify the physiological and psychological variables associated with increased risk for coronary heart disease in a nonclinical sample of healthy adults. Subjects enrolled in a ten-week fitness program were judged to be free of overt cardiovascu- lar disease, as determined by medical history, physical exam, and electrocardiogram. The testing included physiological 46 measures of blood pressure, serum lipids, body weight, plasminogen activator release in the blood, and treadmill performance. Psychological measures included the Jenkins Activity Surveytxadetermine Type A/B behavior patterns and a survey developed from the Friedman and Rosenman interview schedule. Testing was done in the two weeks prior to and in the two weeks after a ten week program of physical condi- tioning. The conditioning program utilized by Blumenthal et al. was 10 minutes of stretching exercises followed by 30 to 45 minutes of continuous walking/jogging (approximately three miles) three times a week for 10 weeks. The subjects were also encouraged to limit their dietary intake of total calories, salt, cholesterol and saturated fats. A general improvement in overall physical condition was documented by significant increases in treadmill performance by the entire group; significant reductions in blood pressure and weight were observed, as well as significant increases in plasmino- gen activator release and high density lipOproteins. Clausen (1977) and Saltin, Bloomquist, Mitchell, Johnson, Wildenthal and Chapman (1968) also documented the utility of physical exercise in reducing blood pressure, blood lipids, and resting heart rate, strengthening lungs and heart, and reducing the risk of heart disease. Additionally, Blumenthal and his colleagues were the first to provide evidence that the Type A behavior pattern may be modified by participation in a regular exercise program. These researchers demonstrated 47 a reduction of Type A behaviors in conjunction with their fitness program. Although their findings are limited by their failure to use a control group, they have provided valuable evidence suggestive of a link between Type A behavior patterns and the future occurrence of coronary heart disease in healthy individuals. The relationship between moderate forms of activity as compared toaasedentary role has been studied by Miller et a1. (1970) Who found more adrenal cortical stress responses in pilots actively engaged in aircraft carrier landing practice than in radar intercept officers who have more of a passive role in the Operation. The radar intercept officers reported more somatic complaints and anxiety; the more active pilots evidenced greater physiological activity and fewer reports of psychological distress. This finding of this study indicates that active physical involvement may be seen as a coping strategy to reduce perceived stress. Psychological Coping and Defending The concept of coping is used to refer to any response to external life stressors that serves to prevent, avoid, or control emotional distress. As an individualized defense against threats in specific situations, c0ping involves responses to both environmental and internal emotional stressors by appraising the threat and responding to it (Lazarus, 1966). Defenses serve to protect the ego against unrest. Regression, repression, reaction formation, isolation 48 undoing, projection, introjection, turning against self, intellectualization, sublimation, displacement and denial are many of the popular defenses the psyche uses to protect itself from perceived threat or emotional distress, at times acting unconsciously (Haan, 1977). Gentry, Foster and Harvey (1972) suggest that defensive functioning may be adaptive, designed to deal with a stressful situation. Hinkle's (1974) research indicates that this mode of functioning may be less situational and more of an overall personality characteristic. He compared the personality variables of healthy people to those with frequent physical illness. Those who remained healthy showed a lack of concern for others, life goals, and involvement in life affairs. Lazarus et al. (1962), Fenz and Epstein (1962) and others have shown that defenses are inversely related to threat and ultimately to the stress reaction on the body. Defenses, then, serve to prevent the emotional correlates of vulnera- bility, depression, and possible decompensation. As part of a holistic model, then, it is necessary to examine coping and defending styles, as they determine how an individual will perceive and react to the environment. Nutritional intake and physical exercise are often overlooked as important determinants of stress, or, they are seen individu- ally as a contributor to stress. The holistic model emphasizes that coping and defending styles, nutritional intake and physical exercise cannot be separated; it is their integration which makes the person and determines how an individual responds to the stresses of everyday life. CHAPTER III DESIGN OF THE STUDY The population and sample, research procedures, hypothe- ses, instrumentation necessary to collect the data, data analysis, and experimental design will be discussed in this chapter. ‘Sample and Population Research subjects were people who telephoned in response to radio, newspaper advertisements and public service messages about a stress management workshOp offered free of charge to the Greater Lansing Community. At the time of the first phone contact subjects were told that the workshop was part of a research project. They were informed that they would be randomly assigned to one of two groups at the first meeting; one group would meet over the next five weeks, the second would begin five weeks later for the same five-week treatment. Subjects were also told that they would be tested on two or three occasions. All respondents were then told a date, time, and place to meet on the Michigan State University campus.' A total of 38 phone contacts were made, with 36 subjects present for the pretest session. One subject decided he could not participate at that time and, thus, the final sample at 49 50 pretest was comprised of 35 subjects, 14 of whom were males and 21 females. Ages ranged from 20 to 64, with a mean Of 38.6 years. Almost all subjects were employed and were well established in their careers as executives for the state government, Oldsmobile, or other large corporations. There were also secretaries, teachers, students, cardiac rehabili- tation patients and retirees (see Tables 4, 5, 6, and 7.)

All subjects were pretested with the same instruments, which are described in further detail in this chapter. All testing instruments were paper- and-pencil, except for blood pressure readings. ~At the con- clusion Of the pretesting period, subjects were randomly assigned to one of two groups. One group was asked to return at the same time and place on a particular date six weeks 52 later. The treatment group then met in the same room for the next five weeks, in which five three-hour sessions were held on the same day of the week, time, and place. On the sixth week, all subjects were posttested. For the next five weeks, the second group then received the same treat- ment under the same conditions, and were posttested again. In order to hold testing procedures constant, the same day of the week, time and room were maintained throughout the workshop period. All testing instruments were the same pre—and posttesting, and were administered in the same format. The room used at all times was a classroom on the MSU campus with a capacity for forty people. Seating consisted Of 40 desk-chairs. A blackboard and overhead projector were available as an aid to the instructor. The two workshOps were conducted by the same instructor in order to maintain consistency Of treatment. For the same reasons, the same nurse was maintained throughout the work- shops and testing intervals. The nurse was told that there would be two five-week stress management workshops and three testing intervals, for which blood pressure readings would be needed. She was paid an agreed-upon sum Of five dollars per hour compensation. In order to have their blood pressure taken, subjects were asked to quietly, one-by-one go to the back of the room. Subjects sat in a chair, and after one minute Of rest, the reading was taken from their right arm. The nurse had a card on each subject, for which she recorded the readings on a weekly basis. 53 The design described above is a Pretest/Posttest Control Group Design with randomization: Pretest/Posttest Control Group Design R 01 X 02 R 01 02 X 03 Where: R = Randomization 1 = Observation 1, or pretest (all subjects) = Five-week treatment 0 X 02 Observation 2, or first posttest (all subjects) 0 3 Observation 3, or posttest after control group received five-week treatment. The independent variables in this study were those of nutrition, physical exercise, and psychological coping and defending mechanisms. A curriculum was devised from the literature review of this dissertation, with articles to supplement and support the information presented. Care was taken to maintain the subjects' interest. Participation from the subjects was encouraged and easily obtained. In order to describe the contents Of the workshOp, a summary is presentedl ”What is Stress?" was the focus of the first week. Hans Selye's definition of stress was discussed, along with the concept of ”wellness." Definitions and illustrations Of atherosclerosis, arteriosclerosis, myocardial infarction,and blood pressure were presented so that participants might understand the relationship between 54 stress and heart disease. The psychophysiology of stress, with a focus on the autonomic system was also presented with the use of visual aids. In the second week, small groups of approximately five each were formed for participants to discuss when, where, why, and with whom stress occurs in their lives. These findings were then discussed as a large group. Internal and external sources of stress were identified as an outcome of this process. The Holmes and Rahe Social Adjustment Scale was administered as an aid to the above. Time was available for reactions to this scale. In the third week, Type A personality and heart disease was discussed, with reference made to Freidman and Rosenman's research. Indicators for Type A personality and suggestions for changing these behaviors were part of this session. Psychological COping and defending were also discussed, with a review of defensive and COping styles. The fourth week was based on self-help techniques, with a description of biofeedback, meditation, concentration, and deep relaxation. All subjects participated in a forty- minute relaxation procedure. The importance of physical exercise and a well-balanced diet were the topics for the fifth week. A consultant came to both workshOp groups and showed subjects how to do aerobic exercises, in which they participated. Practical nutritional information was also discussed, such as the importance Of the essential nutrients, the effects Of alcohol and caffeine on 55 the nervous system, habits revolving around the buying, cooking and eating of food. The conclusion of the workshop servedtflmapurpose of integrating the information presented to support the holistic approach to stress management. - Hypotheses The hypotheses of this study follow from the purpose of the study. The dependent variables, measuring coping and defending behaviors, are scales from Norma Haan's COping Inventory, the Millon Behavioral Health Inventory and scales from the Minnesota Multiphasic Personality Inventory. Nutri- tional intake and physical exercise variables were measured using a checklist. In addition, blood pressure readings were recorded as a dependent physiological variable. Null Hypothesis I: There is no difference in posttest scores between the treatment and control groups on the dependent variable emotional disorder (MMPI). Alternate Hypothesis I: The treatment group will show a decrease in posttest scores as compared to the control group on the dependent varia- ble emotional disorder (MMPI). Null Hypothesis II: There is no difference in posttest scores between the treatment and control groups on the dependent variable ego strength (MMPI). Alternate Hypothesis II: The treatment group will have anincrease in posttest scores as compared to the control group on the dependent varia- ble ego strength (MMPI). 56 Null Hypothesis III: Alternate Hypothesis III: Null Hypothesis IV: Alternate Hypothesis IV: Null Hypothesis V: Alternate Hypothesis V: Null Hypothesis VI: Alternate Hypothesis VI: There is no difference in posttest scores between the treatment and control groups on the dependent variable basic COping scales (Millon Behavioral Health Inventory). The treatment group will have a decrease in posttest scores as compared to the control group on the dependent varia- ble basic COping scales (Mil- lon Behavioral Health Inven- tory). There is no difference in post- test scores between the treat- ment and control groups on the dependent variable psychogenic attitudes scales (Millon Behavioral Health Inventory). The treatment group will have a decrease in posttest scores as compared to the control group on the dependent varia- ble psychogenic attitude scales (Millon Behavioral Health Inventory). There is no difference in posttest scores between the treatment and control groups on the dependent variable Haan's coping scales. The treatment group will have an increase in posttest scores as compared to the control group on the dependent varia- ble Haan's coping scales. There is no difference in posttest scores between the treatment and control groups on the dependent variable Haan's defensive scales. The treatment group will have a decrease in posttest scores as compared to the control group on the dependent varia- ble Haan's defensive scales. 57 Null Hypothesis VII: Alternate Hypothesis VII: Null Hypothesis VIII: Alternate Hypothesis VIII: Null Hypothesis IX: Alternate Hypothesis IX: Null Hypothesis X: Alternate Hypothesis X: There is no difference in posttest scores between the treatment and control groups on the dependent variable systolic blood pressure. The treatment group will have a decrease in posttest scores as compared to the control group on the dependent varia- ble systolic blood pressure. There is no difference in posttest scores between the treatment and control groups on the dependent variable diastolic blood pressure. The treatment group will have a decrease in posttest scores as compared to the control group on the dependent varia- ble diastolic blood pressure. There is no difference in posttest scores between the treatment and control groups on the dependent variable nutrition (checklist). The treatment group will have improved dietary intake in posttest scores as compared to the control group on the dependent variable nutrition (checklist). There is no difference in posttest scores between the treatment and control groups on the dependent variable physical exercise (checklist). The treatment group will exhi- bit increased physical exer- cise in posttest scores as compared to the control group on the dependent variable physical exercise (checklist). 58 Instrumentation The holistic approach to stress management takes into account variables thought to be significant in current stress levels. Previous research has indicated that individual aspects of functioning can be measured as possible stress inducers. Many researchers, however, have not con- trolled for other environmental and internal variables that are also stress producing. For example, Pelletier (1977) cites environmental and cultural influences that create stress (Rosenman et al., 1979; Wolff, 1968). These include nation- ality, eating habits, and place of residence. Recently, nutritional factors have been suggested as stressors, with supporting evidence from physiological research (Julien, 1978; Jenkins, 1978). Julien discussed the chemical reactions triggered through excessive consumption of meat and Jenkins conducted research on the Type A personality and its associa- tion with heart disease. Robbins and Angell (1976)—discuss predisposing epidemiological factors such as elevated lippo- proteins, increased blood pressure, cigarette smoking, and elevated blood sugar. Clausen (1977) and Saltin, Bloomquist, Mitchell, Johnson, Wildenthal and Chapman (1968) have docu- mented the utility Of physical exercise in reducing blood pressure, blood lipids, and resting heart rate. Lazarus (1966) states that psychological stress results when one appraises threat to the system, and the research of Shannon, Szmyd and Prigmore (1962) showed how anticipation of stress resulted in adrenal cortex stress responses. These scientists have 59 sought specific answers in their own fields, overlooking other potentially important variables. This holistic study will, therefore, combine the concepts of nutrition, psycho- logical coping, physical exercise, and physiological responses. A review oftflmaliterature suggests that comprehensive understanding of coping measures and other stress indicators is still in the infancy of its development. For this reason, a variety of inventories are used in this study. The dependent variables in this study include ten measures. The emotional disorder scale and ego strength scale are derived from research on the Minnesota Multiphasic Personality Inventory. Haan has developed coping and defending scales consis- tent with her theory and derived from the California Psychological Inventory and the MMPI. Another inventory used in measuring psychological coping is based on Theodore Millon's theory and research, whose psychogenic attitude scales are used in this study to determine the level of psychosocial stressors, and basic coping scales provide information about personality styles. Physiological measures include systolic and diastolic blood pressure readings. Nutritional intake and physical exercise patterns.are measured from the behavioral checklist. All the subjects were tested at pretest, posttest I, and the second group at posttest II phases of the study. The instruments and their content, reliability, and validity are as follows: 1. Behavioral Checklist--consisting Of items relating to nutrition, psychological coping, and physical exercise. Food 60 group intake and physical exercise patterns were measured from this checklist. The Cronbach Alpha interitem reliability for the total checklist is .74. A pilot study was performed prior to the use of the checklist on a similar sample. 2. Coping Scales--developed by Norma Haan. These COping and defense scales are derived from the Minnesota Multiphasic Personality Inventory (MMPI) and California Psychological Inventory (CPI). They have a mean reliability of .70 based on the Kuder-Richardson formula, and are validated with the CPI and MMPI. COping tended to be positively correlated to the standard scales and defense was negatively correlated on the CPI. Haan refined the scales using a larger sample and cross-validation data. Validity coefficients were lower, but more consistent, ranging from .21 for denial to .57 for intellectuality. The scales follow from Haan's theory and research on ego develOpment. Haan believes that COping is a normative mode to the extent that an individual can deal with internal and environmental situations. If the person's perceptions are beyond assimilatory or accommodatory capa- bility, defenses are used to distort reality. The COping scales and their defending counterparts are as follows: Objectivipy--the ability to separate ideas from feelings to achieve Objective evaluations. Isolation--when the subject is unable to put ideas together and affect does not appear related to ideas. Intellectuality--using many words and abstractions to retreat from the use of affect. 61 Intellectualization--the analysis of a problem in purely intellectual terms in order to avoid or defend from the related affect. Logical Analysis--a systematic organization of personal and environmental situations. Rationalization--explaining and justifying behaviors. Tolerance of Ambiguity--coping with cognitive and affective stimuli and tolerating complex negative and positive feelings toward others. Eggpg--when one is unable to resolve ambiguity. The subject doubts his own perceptions and judgments and is un- able to make up his mind. Empathy--when the subject is able to imagine how another person thinks and feels. Projection--Attributing an objectional tendency to another person insteadcfifrecognizing it as part of oneself. Regression in the service of the ego--using preconscious functioning in a flexible way and in a form of play or humor. Regression--resorting to demanding, dependent, non-age appropriate behavior to avoid responsibility, aggression and demands. Concentration--the subject is able to set aside disturb- ing feelings or thoughts in order to focus on the task at hand. Denial--denying facts and feelings that are painful. Sublimation--finding alternative channels which are socially acceptable to express more primitive affect. 62 Displacement--temporarily and unsuccessfully attempting to control unacceptable feelings or impulses in their original state, and altering their meaning for greater internal or external tolerance. Substitution--expressing tempered, domesticated feelings with flexibility as a substitute to rigidity. Reaction Formation--transforming impulses and affects into their Opposites. Suppression--controlling inapprOpriate feelings for the right time, place, and person. Affect is expressed when apprOpriate. Repression--unconscious1y and purposely forgetting. Haan's COping scales include objectivity, intellectuality, logical analysis, tolerance of ambiguity, empathy, regression in the service of the ego, concentration, sublimation, substi- tution, and suppression. The defensive modes include isola- tion, intellectualization, rationalization, doubt, projection regression, denial, displacement, reaction formation, and repression. The coping mechanisms represent normative modes Of functioning, the defensive operations are used in response to threat to the system. 3. Selected MMPI Scales--emotional disorder (Ed) and ego strength (Es) scales. The emotional disorder scale is very closely related to the Health Opinion Survey (HOS) formulated by Dohrenwend and Dohrenwend (1969). The HOS focuses on psychosomatic complications arising from emotional disorders Of anxiety or depression. The Ed scale is most sensitive to emotional distress, anxiety, guilt, and self-alienation. 63 This scale has moderately high positive correlations with the MMPI faking scale (F) (.66) and negative correlations with Lie (L) (-.23) and K (-.6l). It also correlates posi- tively with depression, psychoasthenia, schizophrenia, and other MMPI clinical scales. The ego strength (Es) scale measures psychological adaptation and emotional disturbances or psychiatric disor- ders. Spiegel (1969) fOund the Es scale to be the single best MMPI predictor separating psychological health in nonpathological subjects from severe psychOpathology in hospitalized psychometric cases. Roessler et al. (1963) found that subjects who were relatively free of serious psychOpathology, as identified by a high Es scale, used less effort in the moment-tO-moment control Of homeostatic processes and, as a result, these psychologically healthy subjects were able to respond promptly, apprOpriately, and effectively to new demands made on adaptational defenses arising from environmental or immuno- logical situations. Roessler (1966, 1967) also found that subjects high in ego strength (as measured by the Es scale) can tolerate greater intensities of cold, heat, and noise, and are able to withstand higher levels of electric shock without complaint. These subjects also manifested relatively greater ranges of autonomic reaction to brief stressors. 4. The Millon Behavioral Health Inventory--this inventory was developed to provide clinical information about psycho- social attitudes and stressors, as well as physical problems. 64 The eight personality scales are called Basic Coping Styles and are derived frombujjrnfs theory of personality (Millon, 1969). The Basic Coping Styles include the following scales: Introspective Style: (32 items) High scorers are emotionally flat, quiet, and untalkative, often appearing unconcerned about their problems. Inhibited Spyle: (43 items) High scorers tend to be hesitant with others and are often shy and ill-at-ease. These subjects tend to keep their problems to themselves but they do seek understanding and attention. COOperative Style: (33 items) High scorers tend to be eager to establish themselves with others and will follow advice closely. They may be inclined to deny the existence Of problems. Sociable Style: (40 items) High scorers tend to be outgoing, talkative and charming. They may be changeable in their likes and dislikes. Confident Style: (33 items) High scorers act in a calm and confident manner. They are likely to fear bodily ail- ments and will follow a treatment plan that will ensure their well-being. Forceful Style: (33 items) High scorers tend to be somewhat domineering, tough-minded, and somewhat distrustful. Respectful Style: (42 items) High scorers are likely to be responsible, conforming and COOperative. They hold their feelings inside and appear well-controlled and serious- minded. These patients usually follow therapeutic 65 recommendations, but there is a strong tendency to deny symptoms. They do not like being sick since this signifies weakness and inefficiency. Sensitive Style: (48 items) High scorers tend to be unpredictable and moody. These patients often seem dis- pleased with their physical and psychological state. Mood changes seem to occur for no apparent reason. Six psychogenic attitude scales were developed to reflect psycho-social stressors. The first two of these scales pertain to relatively objective events which have been experienced as either chronically or recently stressful. The second two relate to attitudes that intensify the subjective impact of past or future stressful events. The last two scales attempt to gauge the status of two significant sources Of potential stress, interpersonal relationships and bodily functioning. The scales are as follows: Chronic Tension: (29 items) High scorers on this scale are disposed to suffer various psychosomatic and physical (ailments. These peOple are constantly on the go, live under self-imposed pressure, and have trouble relaxing. They are most likely to exhibit the Type A behavior pattern (Friedman & Rosenman, 1974). Recent Stress: (20 items) High scorers on this scale have an increased susceptibility to serious illness for the year following test administration. Recent marked changes in their lives predict a significantly higher incidence of poor physical and psychological health than the population 66 at large (Andrew, 1970; Rahe and Arthur, 1968). This scale, then, addresses subjects' perceptions of stress in the recent past. Premorbid Pessimism: (40 items) High scorers on this scale are disposed to interpret life as a series of mis- fortunes that are likely to intensify real physical and psychological difficulties. Depression is ruled out by noting characterological tendencies toward viewing the world in a negative manner on the Future Despair Scale. Future Despair: (38 items) High scorers do not look forward to a productive future life. They view medical difficulties as seriously distressing and potentially life threatening. Social Alienation: (33 items) This scale measures the level of familial and friendship support, both real and perceived. Cobb (1977) and Rabkin and Struening (1976) have found that level Of support is a significant moderator in the impact Of life stresses. Somatic Anxiety: (34 items) High scorers tend to be hypochondriacal and susceptible to minor illnesses, experi- encing an unusual amount of fear concerning bodily functions. Six psychogenic attitude scales were develOped to reflect psychosocial stressors. Six additional scales called psycho- somatic correlates were empirically derived to appraise other emotional factors which complicate psychosomatic ailments or predict psychological complications. 67 The Millon Inventory has been validated on three dimensions: theoretical-substantive, internal-structure, and external criterion. In addition, the test was cross- validated for better generalizability. The median biserial correlation for the items on the personality scales was .47. The psychogenic attitude scales were develOped on theoretical- substantive grounds. Lists were developed and rated by clinicians, with items selected by more than 75 percent of the raters included in the inventory. It was also validated externally with the MMPI, CPI, Rotter's Locus of Control, Beck's Depression Scale, the Life Events Survey, and the Webber-Johansson Temperament Survey. Test-retest reliability on the personality scale range from .77 to .88, with a mean of .82. The psychogenic scale is .85 and the empirical scale .80. 5. Blood Pressure Res.Ponses-‘systolic and diastolic readings were taken by a trained practitioner at all testing intervals and at each weekly workshop meeting. All readings were taken on the right arm in a sitting position after one minute rest. Systolic and diastolic blood pressure readings were found by using a baumanometer merconical blood pressure device with a cuff and stethoscope. Diastolic blood pressure is the pressure on the vascular walls when the heart is at rest. Cattell (1966) found diastolic blood pressure to be signifi- cantly related to trait anxiety or constant stress. A higher diastolic reading reflects greater stress on the vascular walls. Systolic blood pressure refers to the pressure on 68 the vascular walls at the peak of the heart's thrust. Systolic blood pressure is a measure Of situational stress and is therefore more labile than diastolic (Turek, Van Durkuy, Pelgrim, De Keyzer, Von Der Furh, and Voerman, 1977). Blood pressure readings have been correlated with health, with readings greater than 140/90 predictive of potential heart and kidney damage (Wheatly, 1977). Data Analysis Due to the large number of dependent variables used in this treatment, an attempt was made to collapse certain scales into meaningful groups, thereby reducing the possibility of reaching significance merely by chance. As the dependent variables increase, so does the possibility of accidentally achieving significance. Multivariate Analyses of Covariance were used to determine significance levels without com- pounding the alpha level, Or increasing the probability Of rejecting the null hypothesis when it is actually true. Research Design The Pretest/Posttest Control Group Design was used in this study. This is a true experimental design and meets Campbell and Stanley's (1963) criteria for internal validity. Equivalency of groups can be assumed through randomization and a control group is used for comparison. All subjects interested in this intervention received the treatment. 69 Pretest/Posttest Control Group Design R 01 X 02 R 01. 02 X 03 Where: R = Randomization 01 = Observation 1, or pretest (all subjects) X = Five-week treatment O2 = Observation 2, or first posttest (all subjects) 0 3 = Observation 3, or posttest after control group received five-week treatment. CHAPTER IV ANALYSIS OF DATA The data derived from the instruments in Chapter III and a discussion of statistical procedures used to analyze the data will comprise this chapter. Each hypothesis will be restated, with a statement as to whether its null form was supported or rejected. Pearson product-moment correlations were performed on all pretests in order to determine if, and to what extent, relationships existed among the dependent variables. The correlations revealed that there were relationships among the dependent variables; however, the correlations were not large enough to recommend the exclusion of dependent variables due to common factor variance (see Table 8). One high correlation (.793) was found, between diastolic and systolic blood pres- sure, which was expected due to the physiological similarity. Diastolic blood pressure measures the rate at which blood flows through the vascular walls when the heart is at rest, while systolic pressure measures the rate of blood flow while the heart is at work. The diastolic reading is a measure of chronic stress, systolic is more sensitive to situational stress. Both measures were retained as dependent variables in order to determine if subtle differences could be found. 70 71 ooo.~ nah. ~«o.u vv~.n «no. nv«.s dun. ~«~.u vpo.u coo. moo. ens-noun poo—n u«~0uu>m coo.~ was. oo~.- eoa. v-.- ohm. non.- coo. no”. co~. ous..u.m oooun.

Idl‘h 72 Multiple analysis of covariance (MANCOVA) was the method of data analysis chosen for the statistical design described iJI this study. This statistical. procedure, like all regression analyses, expresses the statistical significance of the relationship of the treatment group as compared to the control. Multiple regression is especially useful when there are varied cell sizes, or when other variables are included for control purposes. Multiple analysis of covariance is a more sophisticated multiple regression procedure which tests the significance of the differences among means. Initial mean differences between the experimental groups on a co- variate, a variable correlated with the dependent variable, are thus controlled. In this study, analysis of covariance was used to ensure equivalency of groups at pretest time; therefore pretests, and the additional variable of sex, were covaried. Sex was not tested as a main effect because it would reduce cell size to five observations in one particular cell, thereby limiting statistical inferences. The Hotelling-Lawley Trace and Pillai's Trace tests of MANCOVA were tested for overall group effects on the following posttest dependent variables: emotional‘disorder, ego strength, basic coping scales, psychogenic attitude scales, Haan's coping scales, Haan's defense scales, systolic blood pressure and diastolic blood pressure, with pretest and sex serving as covariates. This MANCOVA test indicated an overall group effect [F(8,8) = 7.01, p<.006], meaning there was a statisti- cally significant difference when the treatment group was 73 compared to the control on the dependent variable posttest scores, with pretest and sex differences adjusted. Subsequent uni- variate analyses were conducted on this group effect to determine which particular variables accounted for the over- all significance. The psychogenic attitude scales proved significant [F(l,15) = 34.86, p<.0001], as well as Haan's defense scales [F(5,15) = 11.65, p<.004]. (See Tables 9 and 10). Hotelling-Lawley Trace and Pillai's Trace MANCOVA tests were then applied to the checklist, with sex and pretest means again covaried. A main effect for group resulted [F(3,18) = 3.81, p<.03], again indicating a statistically significant difference when the treatment group was compared to the control on checklist posttest scores, with initial differences on the pretest adjusted. Subsequent univariate analyses indicated that three variables contributed to the main effect: nutrition [F(l,20) = 8.77, p<.007]; psychologi- cal coping [F(l,20) = 3.50, p<.072]; and physical exercise [F(l,20) = 4.05, p<.057]. (See Tables 9 and 10 for least square means). For purposes Of clarity, each hypothesis is restated below in its null and alternate form, with a subsequent state- ment pertaining to whether the hypothesis was maintained or rejected in the analyses of the data. Null Hypothesis I: There is no difference in posttest scores between the treatment and control groups on the dependent variable emotional disorder (MMPI). 74 TABLE 9 DEPENDENT VARIABLE POSTTEST LEAST SQUARE MEANS (COVARIED) Standard Error Dependent Least Square Least Square Variable Group Mean Mean Ego Strength treatment 22.905 1.205 control 25.939 1.096 Emotional Disorder treatment 13.675 0.723 control 14.279 0.657 Basic Coping Scale treatment 414.264 12.671 control 426.274 11.523 Psychogenic treatment 322.061 10.895 Attitude Scale control 418.519 9.908 Haan's treatment 3.934 0.185 Defensive Scales control 4.881 0.168 Haan's Coping treatment 5.588 0.145 Scales control 5.402 0.132 Diastolic treatment 74.038 2.211 Blood Pressure control 78.539 2.011 Systolic treatment 115.800 3.095 Blood Pressure control 122.600 2.815 Nutrition treatment 24.204 0.773 control 27.542 0.712 Physical Exercise treatment 10.063 0.906 control 21.545 0.061 Psychological treatment 37.603 1.252 Coping control 40.904 1.150 TABLE 10 DEPENDENT VARIABLE PRETEST MEANS Dependent Standard Variable Group Mean Deviation Ego Strength treatment 24.688 5.665 control 26.105 5.685 Emotional Disorder treatment 14.813 2.373 control 14.211 3.242 Basic Coping Scale treatment 412.866 26.779 control 406.684 67.181 Psychogenic treatment 404.600 111.331 Attitude Scale control 356.000 106.277 Haan's treatment 4.069 0.581 Defensive Scales control 4.199 0.509 Haan's Coping treatment 5.381 0.568 Scales control 5.519 0.608 Diastolic' treatment 76.133 9.731 Blood Pressure control 82.737 13.068 Systolic treatment 123.869 17.840 Blood Pressure control 123.316 19.209 Nutrition treatment 25.313 5.023 control 27.789 5.138 Physical Exercise treatment 20.375 3.243 control 20.526 4.647 Psychological treatment 39.313 4.362 Coping control 41.158 4.349 Alternate Hypothesis I: F(1,15) = .31, p
