Foreword

For two decades, I have been responding to questions about the nature of health psychology and how it differs from medical psychology, behavioral medicine, and clinical psychology. From the beginning, I have taken the position that any applica­tion of psychological theory or practice to problems and issues of the health system is health psychology. I have repeatedly used an analogy to Newell and Simon's "General Problem Solver" program of the late 1950s and early 1960s, which had two major functional parts, in addition to the "executive" component. One was the "problem-solving core" (the procedural competence); the other was the representa­tion of the "problem environment." In the analogy, the concepts, knowledge, and techniques of psychology constitute the core competence; the health system in all its complexity is the problem environment. A health psychologist is one whose basic competence in psychology is augmented by a working knowledge of some aspect of the health system.

Quite apparently, there are functionally distinct aspects of health psychology to the degree that there are meaningful subdivisions in psychological competence and significantly different microenvironments within the health system. I hesitate to refer to them as areas of specialization, as the man who gave health psychology its formal definition, Joseph Matarazzo, has said that there are no specialties in psychology (cited in the editors' preface to this book). With all respect to Mata­razzo, whose knowledge of the history of psychology is as immense as his experi­ence with present-day psychology, I would suggest that there are, at least, proto­specializations. We can recognize such functional specializations on the basis of the time required for a person trained to the level of joumeyperson in one or more areas of psychology to achieve an equal level of competence in some other specific area.

As one considers that statement, it is also apparent that the time required dependS" on the areas in which competence was previously attained. There are various bodies of theory, of technique, and of knowledge of environments (tacit and otherwise) that are essential to competent performance in many different settings where psychologists are to be found. There is a loosely defined disciplinary core of theory and knowledge that defines a psychologist. Beyond that, there is a vast amount of specialized theory and factual knowledge far too great to be mastered in total by any individual. So there is selective mastery of sections of the whole that produces, perhaps not specialties, but at least fuzzy sets of psychologists who communicate differently within and between their groupings.

xii FOREWORD

There appears to be a growing consensus that there is a core of knowledge and technique common to all practice of psychology, that is, the professional core. Evidence of such a core would be found, I suppose, in the demonstration that it takes less time for someone who has become a competent professional in one type of application to become competent in another than it takes for persons who have never practiced. Surely, that is a plausible expectation. Are there differing degrees of overlapping subsets of professional competence between industrial-organiza­tional, school, counseling, forensic, and clinical psychology? That seems less certain.

In the final analysis, the demonstration of competence must always occur in a particular environment and problem setting. It is at least an implicit assumption of this book that medical environments and problems have more in common with each other than they do with nonmedical settings, induding mental health settings. The book offers a powerful test of this assumption. For the most part, it takes for granted at least an adequate preparation in a generic clinical training program, and it undertakes to demonstrate how the competence acquired elsewhere must be modified and extended if proficiency in medical settings is to be achieved. The first 16 chapters are concerned with issues common to all practices in a medical environment. Of these, the first 6 chapters focus upon types of hospital structure, education and training, and professional and political issues. Chapters 7 through 10 examine quality assurance, finances, marketing, and computers in practice. Chapters 11 through 16 cover broad clinical and research topics that cross diagnostic categories.

The second half of the book consists of 15 chapters that discuss in detail the clinical considerations that arise as the general principles are put to work in specific work environments. These chapters were written by persons actually experienced in the delivery of such services, and they are rich in the practicalities that must be faced day to day. A special quality emerges from the authors' adl).erence to the principle of presenting the assessment and treatment of particular psychomedical problems in the context of developing and operating a successful service program. This reader found himself frequently surprised by the ingenious way that some practical, micropolitical, or administrative problems had been handled rather than avoided, as has often been the case in other presentations, in which common problems have been glossed over or simply ignored. As one reads about program after program, one has a chance to see how and to what degree the general principles advanced in the introductory sections are realized in actual medical settings.

The descriptions of each of the kinds of programs discussed here could be expanded into books in their own right. There are, in fact, books about a number of the chapter topics. Yet the presentations here are informative and comprehensive, and they are short enough so that they can be read for an overall impression. Thus, this book can serve as an orientation for postdoctoral trainees preparing for careers in medical settings, or for psychologists about to start new jobs in such settings, where the specific tasks to be undertaken are not fully defined, or for experienced clinical health psychologists who propose to expand their work into new settings. At this stage of the development of clinical psychology in medical settings, the psychologist associated with a medical center is likely to be functioning in a somewhat exploratory and entrepreneurial manner. Here is an excellent guidebook for such an exploration.

Preface

The strength of clinical psychology is its scientific basis and its application of scientific methodology to the practice of psychology. It is that psychology of empiricism and that style of problem definition and hypothesis testing that we believe has uniquely fitted the practice of clinical psychology into the medical setting. The expansion of roles and the numbers of psychologists in medical settings set forth in this volume support this position. It was our intent as editors to highlight this growth and the wide range of clinical and nonclinical services provided by psychologists in medical settings. In order to present the information on clinical practice within the proper context, we felt that it was necessary to set the scene by reviewing the characteristics of the medical environment in general, the hospital itself, the politics and professional issues of hospital practice, finances, marketing, quality assurance, research, and the educational and training issues that prepare psychologists for this milieu. In order to truly underscore the strength of psychological practice within medical settings, we asked the chapter authors to stress the scientist-practitioner focus of the field. Clinical programs are described and program development is offered to the reader based on the scientific founda­tions of the practice of clinical psychology.

Throughout the text, the reader will find various generic labels for the activities of clinical psychologists in medical settings. These include health psychology., medical psychology, clinical health psychology, neuropsychology, rehabilitation psychology, behav­ioral medicine, and clinical psychology. The title, Handbook of Clinical Psychology in Medical Settings, reflects our view that the success of psychology in medical settings is rooted in the core knowledge of the field of psychology as discussed by Joseph Matarazzo (1987; there is only one psychology, no specialties, but many applica­tions-American Psychologist).

A brief personal digression by the editors is in order. Each of us entered psychology with an interest in research and practice in "mental health." Under­graduate psychology backgrounds and graduate courses and seminars prepared us for a Boulder model outlook on the mental health field. None of us considered a priori that a medical facility would be a place to carry out the scientific or clinical life of a psychologist. Serendipity found each of us, as part of our training, assigned to a "medical facility." The graduate-student peers of one of us thought that he had received the least desirable practicum spot, as there were "real" mental health facilities within which he could have trained. As they say, the rest is history. The

applicability of the general skills we learned in clinical training fit so well and so successfully within the medical setting and with medical patients that each of us received strong reinforcement, and we have remained within, and in combination, now have experienced well over 40 years of professional time in, that environment. We hope that this text reflects our commitment to and excitement about the medical setting as a place for research on and the practice of clinical psychology.

Given our enthusiasm, we necessarily had to restrict the size and range of the topics so that they could be covered reasonably within this one book. Therefore, the reader will no doubt notice that not all topics, disease entities, diagnoses, or problems found in the medical setting are covered here. Again, the range of possible topics attests to the scope of clinical psychology in medical settings.

Throughout the text, the reader will find mention of guild, turf, or political issues that can and do influence the daily practice, academic, and financial free­doms of clinical psychologists in medical settings. The cartoon shown below appeared in the New Yorker and hangs in the office of Bryant Welch, Executive Director of the American Psychological Association's Practice Directorate. Little interpretation is needed to see the irony of the heretofore unwanted dragon being asked to address his foes. However, it is time that clinical psychologists in medical settings not see themselves as dragons (or the outsiders we once were) but begin to see themselves as sitting in the audience with the rest of the knights. Our armor may be less well heeled or just as shiny as the next knight's; our armor may be more­or-less tarnished; our helmets may sport blue rather than purple plumes; but we are now and will continue to be members of the modern-day health-care alliance. It is

think the fJery fact of my presence here today is a major breakthrough."

the theme of science and service and the politics of competence that support our place in the medical setting, not the appearance of our knightly accoutrements.

We would like to thank our chapter authors for their energy and enthusiasm. Their forbearance through the editorial process and their gracious acceptance of our comments are gratefully appreciated. We thank Eliot Werner, Executive Editor at Plenum, for his interest and guidance in bringing a dream and an outline to press. We also want to thank our secretaries, Vanessa Schaeffer, Pat Barnes, and Elaine Richardson, for their hours of typing, photocopying, phone calling, and patience.

We owe a debt of gratitude to our professors in psychology, who helped breathe life into the Boulder model, and to our colleagues in psychology, medicine, and psychiatry, who help reinforce the vitality of our professional lives. Thanks are also due to Edward Sheridan for his encouragement and helpful suggestions throughout this project. And a final, special thank you to Ira H. Sloan, Chairman, Department of Psychiatry, Evanston Hospital, for his support in providing a truly collegial, multidisciplinary environment.

Glenwick et al. (1987) have offered a discussion of helpful suggestions and encouragements for, and the pitfalls encountered in, editing a book. Thus far, all of their insights have rung true to the present editors. They suggested that working with coeditors who have a similar value system is a strength. The present editorial product, for us, represents that strength and reflects a process of equal input, equal energy, equal commitment, and equal responsibility of the editors for the whole of this project.

Time spent on this endeavor was personally and professionally enjoyable. Relationships renewed or established with colleagues across the continent reflect for us the vitality of clinical psychology in medical settings.
