Kahn (Ph.D., Southern California and Sc.D., University of Mainz, Germany), internationally known psychologist and educator, is Professor and Head of the Department of Behavioral Science, Southern Colorado State College. He has served as senior counselor at the University of California, psychological consultant to the Los Angeles City School System, chief clinical psychologist for a number of large diagnostic neuropsychiatric hospitals and community mental health clinics, and has held teaching positions at the University of Southern California, the University of Maryland, and Wittenberg University. Dr. Kahn has won numerous national awards for research and teaching, including Outstanding Educator in America. He has done pioneer work in audio-visual-tactile rhythm therapy and introduced hominology, a new way to view and study the whole man. Dr. Kahn is the author of several books and numerous professional articles as well as the designer of a number of psychological tests used in the United States and abroad. He is the Founder and first President of the International Society of the Study of Symbols and Honorary President of the Japanese Society for the Study of KTSA. James T. Cameron (Ph.D., University of Colorado) is Associate Professor of Psychology at Southern Colorado State College and Director of the Crisis Telephone Training Program. His other professional interests include private practice, direction of a sensitivity training program, and consultation and evaluation of educational and mental health programs. Martin B.

His primary interests are in the delivery of health care, forensic psychiatry, the professional training of psychiatrists, psychologists, and medical students, and development of concepts of acute and crisis triage facilities. Dr. Giffen is a member of several professional societies and his published works concern the use of hospital facilities and theory of forensic psychiatry. Preface This book represents the collaboration of a professor of psychiatry at The Medical School, The University of Texas Health Science Center, San Antonio, Texas; a counseling psychologist, who is a counselor and an associate professor of psychology at Southern Colorado State College; and the Chairman of the Department of Behavioral Science at Southern Colorado State College, who has had many years of practical experience in the field of clinical psychology. In effect, the book represents a greatly expanded edition of an early work, Psychological Techniques in Diagnosis and Evaluation (Pergamon Press, 1960) by Kahn and Giffen. The authors have rewritten the earlier materials and brought them up-to-date. There are many new chapters in addition to reviews and discussions on psychotherapy, counseling, in novative methods, and other features not found in the earlier edition. Dr. James T. Cameron has managed the production of this new book and as a coauthor has added to it considerable material reflecting his experience as a modern therapist and educator. The authors attempted to bring to the reader the many-sided problems that contemporary psychology faces. At the same time, the contributions that psychology can make in many areas of human concern have been described in some detail. We tried to answer as fully and clearly as possible the question: What do modern practicing psychologists do, and how do they do it? We wanted to make this answer intelligible to our colleagues in the other professions that deal with human welfare—social workers, correctional workers, and those who are employed in the various specialties of medicine, law, the ministry, and education. The xi xíi Preface book was also designed to be used as a textbook for courses in clinical and counseling psychology. It was the intention of the authors to make available to the reader the essential information that could explain the kinds of methods, skills, techniques, and services that clinical and counseling psychologists can render. A serious effort was made to present both sides of controversial issues and to give a balanced view throughout the book of all those topics that are subject to differences of opinion. An attempt was also made to present those methods, tests, and therapeutic techniques that are representative of the contemporary scene in psychology. However, if one of the authors had a special expertise or a unique experience within the field of clinical psychology we did not hesitate to include information on the topic if we felt that it might be of interest to the reader. We also kept in mind that the reader might be interested in the future role of psychology as a profession. Prediction is a hazardous matter; however, a number of topics were selected in Appendix A that the authors believed represent trends in the future development of psychol ogy as a science and profession. It is hoped that the reader, whether colleague or student of psychology, will find the contents of these pages interesting and stimulating. Further more, we hope that the book will give him an overview of that challenging and sometimes puzzling profession—psychology as it is practiced today. We wish to acknowledge with special gratitude the loyal support and invaluable editorial contributions of Shirley Kahn, Jean Cameron, and Margaret Giffen. Theodore C. Kahn, Ph.D., Sc.D. CHAPTER 1 Introduction The recognition of clinical psychology as a bona fide member of the psychological profession has less than 100 years of historical precedence. It is a mere infant historically when compared with the older, more established physical sciences. Even within the profession of psychology, the clinician is considered a "late bloomer." In view of this, the growth of the profession has been astonishing. Today, clinical psychologists consti tute approximately 29 percent of all psychologists and, when combined with the allied counseling field, this figure is increased to almost 40 percent [319]. Not only has the introduction of clinical psychology altered the complexion of the psychology profession, but its internal composition has constantly been subjected to experimentation, exploration, and an ever- changing image. It is remarkable that this comparatively young profession has attracted such a large number of members in less than a century while still reflecting an unsettled and ever-evolving identity. A perusal of historical antecedents and current movements may be helpful in bringing this complex and sometimes conflict-ridden profession into perspective. THE MEDICAL MODEL It is impossible to discuss the history of clinical psychology as an isolated movement. Other professions, especially medicine, have influ enced the clinical identity of psychology. Even the name clinical—which comes from the Greek word klinnikos, meaning "of the bed"—is adapted from medical terminology. 2 Introduction Medicine had the responsibility to treat the mentally ill and to provide services for the maladjusted. Thus, clinical psychology initially was modeled on the medical profession and psychologists concentrated their efforts on the assessment and treatment of mental and physically related pathologies. This alliance with the medical profession has provided the clinician with a useful function but it has also led to some problems, which will be discussed later. Other historical trends have affected the professional development of the clinical psychologist. His commitment to psychological research has guided much of his training and professional behavior. A growing emphasis has been placed on the integration of research and treatment and this has given the practice of clinical psychology its identity. Many different people have made significant contributions to the early movement in clinical psychology. The humanitarian efforts of such people as Philippe Pinel (who started the humanistic reform in mental institu tions) in France during the 19th century, the crusades of Dorothea Dix (American crusader for humane treatment of the mentally ill), and later the work of Clifford Beers (founder of the National Committee for Mental Hygiene and author of the book A Mind That Found Itself [35]) brought about major changes in the physical conditions of mental asylums and in the treatment of the mentally ill. Methods of diagnosis and treatment were also being developed during this period. Emil Kraepelin established a systematic method of classifying pathology by symptoms. His work had a major influence on the early establishment of a diagnostic model for pathology. Treatment, which was long neglected, was also being consid ered. Jean Martin Charcot demonstrated how physical symptoms in hysteria could be alleviated with the use of hypnosis. The impetus of his early discoveries greatly influenced the work of Sigmund Freud and others. It was Freud more than any other individual who established the first comprehensive system of psychological techniques for treatment. Freud's impact was phenomenal and his contributions affected almost every facet of psychology. Most important to the field of cHnical psychology were Freud's theories, hypotheses, and explanations of human behavior, particularly in the area of maladjustment. This, coupled with his treatment method (which he termed psychoanalysis), supplied the basic model for the many methods of therapy and the numerous theories of abnormal behavior that followed. His work also provided the stimulus for ensuing volumes of research that have greatly enhanced the understanding of psychology. The Scientific Model 3 Adherence to the medical model has given the clinician a useful and recognized position in the field of mental health. However, for some psychologists it has also led to some conflicts in professional role identification. Even more basic to this problem than the medical model was the psychologist's role in providing a variety of services to those who suffered from pathology. Historically, the clinician perceived himself as a provider of services to those who were ill; it was this position that narrowed his vision to other aspects of clinical psychology in which he participates today. THE SCIENTIFIC MODEL Other historical trends have affected the clinical model. The commit ment of psychologists to legitimize the field of psychology as a science has led to an emphasis on research and methodology, which has provided structure for much of the academic training and professional experience. The acceptance of the scientific method within psychology dates from the early work of Wilhelm Wundt, who established the first psychological laboratory in Leipzig, Germany, in 1879. The rigors of the laboratory allowed Wundt to apply objective measures and to utilize strict controls for his experiments. Possibly more important was the fact that the program established by Wundt was utilized in the training of a number of young psychologists who later became prominent and gave direction to the new science of psychology. Paralleling the work of Wundt was an equally ingenious laboratory approach developed by Ivan Pavlov in measuring the connection between a stimulus and a response. In his early work with dogs in the laboratories, Pavlov [284] was able to create what he termed a "psychic secretion" by pairing the tone of a tuning fork with meat powder blown into the animal's mouth, causing salivation. The pairing was repeated a number of times until the tone by itself could produce the response (salivation). Thus, Pavlov demonstrated by the use of objective experimental methods that behavior could be modified. It is from this basic premise that one therapeutic approach in the area of behavior modification was devel oped. One of the students trained at Leipzig was Lightner Witmer. At the University of Pennsylvania in 1896, this American psychologist adapted his laboratory training and techniques to a clinical setting designed for the assessment and treatment of emotional disorders in children. Witmer is given credit for applying the term "clinical" in psychology and for 4 Introduction demonstrating that the rigors of the laboratory can be utilized in a practitioner's setting. William James was another product of the Wundt laboratories. He became the most influential American psychologist and his work carried on Wundt's tradition of research and methodology. An even stronger advocate of objective experimentation was John Watson, who rejected the early ideas of introspection and, instead, stressed prediction and control of behavior through rigorous objective methodology. He started the behavioristic movement in the United States, which later fell into disrepute but still has a number of adherents. Continuing psychological inquiry into the area of learning were such researchers as E. L. Thorn- dike, who proposed specific laws of learning, and B. F. Skinner, who has become the major proponent of operant conditioning. The currently popular behavior modification therapy can trace its roots to the basic premises of these learning theorists. MEASUREMENT OF INDIVIDUAL DIFFERENCES The recognition and measurement of individual differences has also made a unique and major contribution to the role of the clinical psychologist. Possibly from the first written notation of individual differences (reflected in the disputed calculations of the distance to Venus by two astronomers, Kennybrook and Maskelyne, in 1796) to the work of Charles Darwin in the early 19th century, man has become increasingly aware of individual differences and the need to measure and understand them. Darwin's work stressed individuality and how differences made some animals more adaptable than others. He emphasized the scientific ap proach, which appealed to the infant science of psychology. However, more important to the development of psychology was the work of Darwin's cousin. Sir Francis Galton, who directly applied psychological techniques to the study of individual differences in human behavior. Galton's interest centered in the area of heredity and its effect on individual differences. He carried out a number of studies on lineages of successful, prominent families and also families who were marginal in their adjustment. He recognized the need and provided the impetus for the development of a quantitative method to validate his research. The statistical techniques of correlation were developed by Karl Pearson from a grant supported by Galton. Galton also designed a number of tests to measure the various facets of individual differences, including intelli-
