A set of cognitive theories says depressions arise because of the interaction between depressogenic thought styles and painful events. The depressogenic thought patterns presumably precede the depression and are a central cause of the subsequent depressions. 0n the other hand, a second set of theories says these depressive thought styles arise out of the depression but do not precede it and are thus not a cause of depression. To test these alternate thought-first and affect-first models of depression, two experiments were conducted. The subjects in the first experiment were 62 Michigan State University undergraduate women; in the second experiment, the subjects were 24 male and 23 female M.S.U. undergraduates. The two experiments followed a similar design: subjects completed a set of questionnaires on their thought style, their level of depression and their mood; they were then randomly assigned to either a control condition or to an experimental condition designed to induce a mood change; afterwards, the initial questionnaires were again completed. The two experiments differed in the experimental induction used to alter mood states and in the timing: in experiment one subjects returned for a second session, while experiment two was entirely completed at one sitting. Experiment one used the Velten Mood Induction Procedure (or VMIP) to create neutral, depressed and elated moods. This procedure consists of having students sit alone in a room and read aloud a set: of 60 mood related statements. In experiment two, mood was altered by watching the movie "Peege"; the control group saw a neutral science movie. The following instruments were used in both experiments to measure depressed mood: the Beck Depression Inventory or BDI; the Multiple Affect Adjective Check List or MAACL; and a Personal Feelings Scale or PFS. The measure of depressive thought style was the Attribution Style Questionnaire or ASQ. The results supported two conclusions. First both inductions successfully created depressed moods, although the procedures also induced additional emotions, most noticeably increased anxiety. Second, there was some support for the thought-first hypotheses of depression. There were significant predicted differences on one of three depressixnn comparisons in experiment one and on two of six comparisons in experiment two. This support is stronger than it seems because sex interactions in experiment two necessitated separate analyses by sex, making the cells used for the comparison quite small in size. In addition, no comarisons were ever significant in a direction opposite to the predictions. The affect-first hypotheses were not supported. Furthermore, no relation was found between induced elation in experiment one and either the affect-first model or the thoughtrfirst model. The discussion suggested future avenues of research which might use naturalistic studies rather than experimental studies. The failxxre to find any support for the affect-first model was explained as being partly due to the experiment’s failure to fully test the affect-first model, most notably because informed consent procedures made it impossible to alter mood without subjects being aware of the mood change. Finally, the discussion raised the possibility that the two models are actually alternate phases of a single feed-back loop process. This dissertation is dedicated to the loving memory of my father Max Ermann who died this year before he could see me graduate. ii ACKNOWLEDGEMENTS I would like to thank Professor Rabin, my dissertation committee chairman, for his advice and support. His careful reading of the dissertation made it a much better manuscript. His belief that the basic research question I was considering was worth investigating provided reassurance during the uncertain transition between early conception and the final prOposal. His research advice moderated my impetuosity; his insistence that I do a pilot study, for example, enabled me to skirt some mistaken approaches. But most of all, I wish to thank Dr. Rabin for his friendship and support throughout my graduate school career. He was an excellent teacher, a model of professional integrity and decorum, and the very exemplar of the scientist- practitioner clinician he sought to create in his graduate students. In saying he will always have my esteem and affection, I know I am only joining a long line of like students. Dr. Messe' was the methodologist on this dissertation, a capacity he had previously served on my masters thesis. On this work, as on the earlier work, most of the credit for the analysis belongs to him; any errors are naturally my own. Clinicians, I suspect, generally have a better conceptual understanding of research design than they have a strict mathematical understanding, and I am no exception. The value of the methodologist to peOple like me is directly prOportional to both their knowledge and their patience, and in these regards, Dr. Messe’ is iii the methodologist par excellence. I take the knowledge for granted, but the patience I know of first hand, since I sorely put it to the test whenever I started my tortured explanations of the project. Such clarity as may exist in my plan of analysis and results sections owe much to his careful reading of an early draft. In addition, Dr. Messe' has been a friend and source of encouragement in all my research endeavors; I especially treasured this research encouragement as my most severe doubts early in my graduate school career centered on my ability to perform research. Dr. Ferguson made a number of valuable suggestions which improved the basic experiment of this dissertation. Her advice here, as elsewhere during my graduate school career, was astute and sensible. She has always been an excellent teacher, a fine clinical supervisor and a friend throughout my graduate school career. One of my comprehensive questions was written for her this year, and she gave me enough leeway on the project so that it became the most exciting theoretical endeavor I attempted while in graduate school and one which I expect will engage my interest for some time to come. This is typical; looking back, I see many of the areas which are of most interest to me started in various classes of hers. Dr. DeRath focused my attention back onto the clinical issues raised by the theoretical question I was addressing. His ability to bring me back to earth, as it were, continues a long pattern in our relationship, for Dr. DeRath was one of my first clinical supervisors, both at the M.S.U. Psychological Clinic and later during my first internship at Ingham Community Mental Health Center, and supervisors for novice clinicians must always see that their students do not lose the iv actual clinical data in a propensity for abstracting. Dr. DeRath has always shown a personal interest in my career develoPment and has been the source of quite useful career advice to me over the last six years; I only regret that I did not follow even more of it. My wife Mary was helpful in more ways than I can ennumerate, but perhaps most of all for her support and c00peration in seeing this to completion. She not only picked up the slack in family matters whenever I was spending long days and nights collecting data or writing, but even well before this year, she tolerated and reduced my bouts of anxiety during the long stretches when I was afraid I might never find a research topic, and, in what was surely the most torturous part of this all for her, she patiently listened to me as I wove through and then rejected dozens of research ideas, ranging from the ridiculous to the impossible. My son, Sam, too, deserves some mention, if only because his easy-going nature made it easier to forgive myself for those times when my anxiety about this work left less of me available for him than he deserved. David Hayes deserves a special place in this list of acknowledgements. I was in constant touch with David during the germinal stages of this proposal and he read and commented on the prOposal before I presented it to my committee. Most of all, he was an ever-available sounding board for my ideas and my worries, and a touch- stone of reassurance that I would eventually complete this project. David and his wife Peggy also fed me supper and offered me a place to sleep many a night when my data collection in East Lansing was continuing too late for me to return to my home in Ann Arbor in time. The food was always good, but the encouragement was even more nourishing. I deveIOped an interest in doing research on depression.
