One-third of these students (n= 106), surveyed during their surgical clerkships, reported apprehension about observing and assisting in surgical procedures. The present study attempted to investigate the effect of a treatment program on these adverse reactions and on medical students' learning, attitudes, and career preference. Forty-five first and second year students from the Colleges of Human and Osteopathic Medicine at Michigan State University participated in the study. A three-group posttest-only control group design was used. Group One received two Interpersonal Process Recall (IPR) laboratory sessions. These students were then videotaped while observing an operation, watched the videotape, and disCussed their reactions. Group Two students observed one operation. Group Three received no treatment. All students observed an operation and completed eight instruments measuring emotional-physiological reactivity, learning, attitudes toward themselves and surgeons, career preference, and impressions of the operating room experience. Analysis of variance and chi-square analysis indicated no significant differences among the groups. The results of chi-square analysis of the career preference measure approached significance, suggesting a more positive attitude toward aurgery on the part of Group'One students. Sample size, however, required cautious interpretation of this result. Medical student interest in surgical experiences early in medical school was discussed. The collaboration of psychology and medicine in this surgical education study was emphasized.

The investigation was an exploratory experimental study evaluating the effectiveness of an Interpersonal Process Recall (IPR) (Kagan, 1975, 1979) pre-surgical clerkship experience. The purpose of the treatment was to increase learning and decrease the negative impact of common operating room stimuli on medical students in their early surgical training. This chapter includes a discussion of the events lea- ding to the explication of the incidence of the problem, the need for the study, the theoretical framework in which the problem was conceptualized, a brief description of the treatment approach, definition of terms, assumptions employed in the study, and a general statement of the research questions. Incidence Of The Problem Through discussions with students before, during, and after the students' participation in the surgical clerkship, Coppola and Cochran (1979) noted that some students tended to be frightened by or apprehensive about observing, assisting in, or performing surgical procedures“ Coppola and Cochran reasoned that, depending upon the actual incidence of such reactions in medical students, these reac- tions might have significant effects in two areas: 1) the medical student's attention to the learning of necessary information and skills involved in surgery and 2) the student's viewpoint toward and possible consideration of surgery as a career specialty.‘ Coppola and Cochran's specific concerns were that students' apprehension about surgery might detract from their learning in the operating room, contribute to a.re1atively negative attitude toward surgery and/or surgeons, and perhaps dissuade some students from considering surgery as a career specialty. The latter concerns related to issues of medical student self-percep- tion and attitudes about surgery and surgeons, and the influence of these factors on career selection. If some students perceived themselves as overly reactive to common surgical stimuli and judged that this over-reactivity was unchangeable or maladaptive in terms of consideration of surgery as a career specialty, then these students might rule out surgery as a career option. Stated another way, if some medical students held a stereotypical view of surgeons 3 as insensitive to surgical stimuli, and if these students saw themselves as highly sensitive to these stimuli, they might have viewed themselves as unsuitable for surgical careers. The stereotype of the surgical personality for some students may have been transformed into a self- fulfilling prophecy. "The underlying assumption . .. is that surgical professional competency requires traits and characteristics in the surgeon which are incompatible with the needs of patients for sensitivity, compassion, and understanding during an experience of great personal pain and danger" (Coppola 8 Cochran, 1979). If this was in fact occurring, then surgery may be losing a group of bright, sensitive and thoughtful recruits who might otherwise be interested in surgical careers if they could be trained to cope successfully with their reactions to noxious surgical stimuli (Coppola, 1980). In.order to first investigate the actual incidence of this phenomenon, Coppola and Cochran devised the Apprehen- sion to Surgical Procedures Questionnaire (ASPQ) which was administered in March and June, 1979, to Michigan State University College of Human Medicine students at the end of the ninth week of their twelve-week surgical clerkships. These were third and fourth year students, a11«of whom had completed a minimum of two years of pre-clinical coursework. The questionnaire asked several short-answer questions about the presence, nature, extent, intensity, duration and change of such adverse reactions to surgical stimuli. The results 4 from this first questionnaire confirmed Coppola and Cochran's earlier observations. Of 72 medical students surveyed on their surgical clerkships, one—third indicated they had experienced physiological reactions such as feeling faint or nauseated while they were in the operating room. Students were asked to describe the reactions they had experienced, to determine if these reactions were related to specific types of operations or operating room stimuli, and to describe what they had done to cope with these reactions. They were also asked to check the extent to which each of 42 specific stimuli bothered.thenu The data indicated there were emotional as well as physiological components to these reactions and that the reactions frequently seemed tied to specific (”excision of nails of great toes") or general 1 is used") opera- ("1ong operations; operations where Bovie ting room stimuli. Interpersonal stimuli (e4L "surgeon's expression of anger," "surgeon making disparaging remarks", distinct from actual surgical or anatomical stimuli (e4p ”intubation," "incision," "blood"), also were identified by students as contributing to their adverse reactions in the operating room. The confirmation of the existence of adverse physiological/emotional reactions to both "surgical” and ”interpersonal” operating room stimuli on the part of 1Bovie: electro-cautery unit 5 approximately one-third of the medical students surveyed led Coppola and Cochran to consider more seriously the implica- tions of this phenomenon. Did these adverse reactions interfere in some way with the students' learning process while in the operating room? Did these reactions perhaps affect the medical studentfs attitudes about self or toward surgeons and surgery in such a way that the student might: 1) have a relatively negative attitude toward surgeons or surgery, or 2) decide against surgery as a career specialty? The incidence and intensity of medical students' reac— tions to surgical stimuli as reported on this questionnaire seemed to be inversely related to surgery-related experi- ence, that is, the more experience the less reported reac- tion, but neither the level of the reactions nor the process by which the reactions decreased was clear. For example, if the student's initial adverse reaction to surgical stimuli was 20 on a scale measuring the intensity or duration of the reaction, it was not clear if the reaction decreased to 10 or 5. Since this was unclear, the relative effect that a preparatory treatment experience might have on the level of these reactions was also unclear. With these issues in mind, Coppola and Cochran began considering strategies for further verifying the incidence of the problem as well as for investigating the possible relationship>between these reactions and the learning and attitudes of medical students on their surgical clerkships. Though still in an exploratory stage, these ideas seemed 6 sufficiently well defined to be subjected to experimental study. Realizing that these reactions to various operating room stimuli were the dependent variables in this situation, Coppola and Cochran began considering means of ameliorating the impact of these stimuli on medical students and thereby perhaps increasing their learnimg and improving their attitudes toward surgeons and surgery. A training experience was sought which would be pertinent to: l) The identified stimuli, both surgical and interpersonal 2) 'The physiological/emotional components of the medical student's reactions to these stimuli. In addition, Coppola and Cochran sought a training experience which would be positive, both in process and outcome, for the medical students by fostering increased awareness, acceptance, and perception.of control of their reactions and of themselves. Aware of the research of Kagan to increase the interpersonal effectiveness of medical students in patient interviews through the use of the Interpersonal Process Recall (IPR) method (Kagan, 1975, 1979), Coppola and Cochran (1979) concluded that this method might influence students' adverse reactions to surgical stimuli and students' learning in their surgery clerkships. Embelton's study, conducted in 1979, grew out of the collaboration of Embelton, Kagan, Coppola, and Cochran in the initial exploration of this possibility. Embelton used a matched- 7 pairs design to test the effectiveness of a treatment consisting of two laboratory I.P.R. sessions (viewing videotaped "vignettes" of actual and simulated surgical situations) on early surgical learnimg and anxiety in medical students. Embeltonfis study is reviewed in Chapter 2. The IPR method employed in Embeltonls study and in this study is discussed specifically in this chapter and in Chapter 2, and the general rationale for the choice of this treatment approach is presented in Chapter One. The present study grew directly from the Embelton study and was an attempt to: 1) Strengthen the Embelton treatment by adding an instructional videotape and an actual operating room IPR session. 2) Improve the design by using three groups instead of two and by using experience as a blocking variable. 2” Improve and expand the scope of the outcome measures by improving their objectivity and validity. 4) Incorporate an exploration of medical student attitudes toward themselves and surgery. The remaining sections of this chapter address the need for the study, the theoretical framework used in the present study, a discussion of the treatment approach, definition of terms, assumptions, and a statement of the research ques- tions. Need For The Study Although Embelton found no significant differences between experimental and control groups on either learning or anxiety, this lack of significant differences could have resulted from weaknesses in the treatment, design, and/or outcome measures (Embelton, 1981). The present study addressed these weaknesses in a more rigorous attempt to discover any differences which might exist but were not found by Embelton. Specific modifications and additions made in this study are presented in Chapter Two. The need for the present study was further indicated by the results of the administration of the 1980 ASPQ question- naire to sixty-eight medical students on their surgical clerkships. These results confirmed the earlier finding that nearly one-third (29%)iof theSe students experienced some unpleasant reaction to operating room stimuli. The present investigation was significant for two reasons. First, the investigation attempted to determine if a relationship existed between students' reactions and subse- quent learning (observation) in the operating room. The importance of such a relationship becomes clear when one considers the ubiquity of the surgical clerkship in American medical education. Of the 130 North American allopathic medical schools indexed ix: the 1978-79 Association of .American Medical Colleges Curriculum Directogy, 120 included a required surgical clerkship of between four and sixteen weeks. These clerkships include general surgery clerkships 9 as well.as clerkships in various surgical specialties. If adverse emotional/physiological reactions to surgical stimuli were present in about one-third of all medical students entering their surgical clerkships and if these reactions were found to significantly interfere with observation in the operating room, important issues would be raised for surgical education. The meaningful significance of the results, as well as other specific data to be gathered in the study, could be a guide for further research as well as foster consideration of a heretofore largely ignored phenomenon in surgical education. Secondly, a study was needed to determine if a relationship existed among these adverse reactions to surgical stimuli and medical students' attitudes toward themselves and toward surgery as a career specialty. Embelton (1981) confined his study to the investigation of the adverse reactions/learning relationship. In addition to exploring this relationship more rigorously, the present study sought to investigate this adverse reactions/attitudes relationship. Previous reports (Burke, 1979; Linn, Pratt, & Zeppa, 1979; Chapman, 1976) have indicated the importance of clerkships in the career decisions of medical students, especially the approximately one-third of students who have not made fairly firm career decisions by their senior year (Chapman, 1976). But there has been little actual research on the influence»of clerkships on career choice. If there is a link between the medical studentls experience on the 10 surgical clerkship and later career choice, then the possible influence of adverse reactions to surgical stimuli on the student's surgical clerkship experience becomes an important issue. This issue is perhaps most clearly focused in the medical student who is one of the one-third who seem to‘experience adverse reactions as well as one of the one- third who are unsure of their career choices. The present study, though it did not undertake a longitudinal analysis of actual career choices of the participating students, did attempt to explore student attitudes toward surgery and other specialties and the possible relationship of these to adverse reactions to surgery. In addition, apart from concerns regarding the effects of adverse reactions on learning and attitudes toward surgery, the present study also addressed the relationship between these reactions and medical students attitudes toward themselves in general and specifically toward themselves in the operating room. The need for investigation of this question related to the issue of the possible relationship between medical student self- perception regarding these adverse reactions and the stereotype of the surgeon as a cold, insensitive mechanic. The following section outlines the theoretical framework in which the adverse reactions/learning (observation) relation- ship was conceptualized in the present study. 11 Theoretical Framework An investigation of the early surgical learning of medical students requires some conceptualization of the phenomenon of learning. Of the three major schools of psychological thought, psychoanalytic and its derivatives, behavioral, and existential/phenomenological, the behavioral school has concentrated most on investigating the specific processes and events by which learning occurs. From its origins of classical and operant conditioning, in which the organism was thought to respond quite simply and directly to external stimuli and in which response strength was determined by reinforcement, mainstream behaviorism gradually moved to a position of recognition of "intervening variables” CTolman, 1938) in its basic stimulus-response- reinforcement paradigm. This position marked acceptance of the organism's mediation of its response through the occurrence of internal processes and events, the "intervening variables." Central among these variables were sensation, perception, memory, and thinking. The acceptance of variables present in the learning process other than those which are observable pointed toward the possibility of common ground with psychodynamic approaches, which emphasized intrapsychic structures and processes, and with existential approaches to the person, which emphasize the individual's unique experience. From this point, investiga- tion into the nature of these intervening variables, the hypothesized internal structures and processes by which 12 learning occurs, moved toward research and theorizing which focused primarily on building conceptual models to represent the learning process and on testing these models experimen- tally. Animal learning and verbal learning studies concen- trated primarily on the investigation of relatively simple processes of association. In contrast, a new line of research extended in recent years to the study of more complex mental structures and processes, e4L, perception and memory. The field of cognitive psychology, drawing on information theory, computer science, and linguistics, has gradually emerged as an integrative effort espousing gener- ally the following set of beliefs regarding the way by which the mind processes information: 1. The importance of the selection of stimulus information. Most of the time more information impinges on us than our limited capacities can handle. 2. The importance of selecting appropriate processing strategies (largely under voluntary control) to meet the demands of the task. 3. The development of cognitive structures. After repeated applications of processing procedures, stable cognitive structures emerge. 4. The interrelated functions of the parts of the human mind as a coherent system. 5. The constantly active nature of cognitive processes. The system is always active and at 13 work. (Reynolds & Flagg, 1977: p. 12) Inherent in the cognitive psychology view of learning is a reliance on models to approximate and attempt to explain the processes of learning. These information-processing models posit internal mental structures and the kinds of processing which these structures accomplish. One such model drawing on several others, was proposed by Gagne' (1977). This model, as well as a discussion of the specific structures and processes it contains, is presented below. Although learning can be explained in psychodynamic and, perhaps less clearly so, in existential terms, the information processing model is the theoretical model of learning employed in this study. The model has the advantages of relative precision, parsimony and operationalism and does hold promise for learning research, but a significant weakness of the model, and of cognitive psychology in general, is discussed following the presentation of the model.
