It is particularly gratifying to prepare a second edition of a book, because there is the necessary impli cation that the first edition was well received. Moreover, now an opportunity is provided to correct the problems or limitations that existed in the first edition as well as to address recent developments in the field. Thus, we are grateful to our friends, colleagues, and students, as well as to the reviewers who have expressed their approval of the first edition and who have given us valuable input on how the revision could best be structured. Perhaps the first thing that the reader will notice about the second edition is that it is more extensive than the first. The volume currently has 41 chapters, in contrast to the 31 chapters that comprised the earlier version. Chapters 3, 9, 29, and 30 of the first edition either have been dropped or were combined, whereas 14 new chapters have been added. In effect, we are gratified in being able to reflect the continued growth of behavior therapy in the 1980s. Behavior therapists have addressed an ever-increasing number of disorders and behavioral dysfunctions in an increasing range of populations. The most notable advances are taking place in such areas as cognitive approaches, geriatrics, and behavioral medicine, and also in the treatment of childhood disorders.

Mental retardation has probably existed for as long as mankind has inhabited the earth. References to seemingly retarded persons appear in Greek and Roman literature. Examination of Egyptian mummies suggests that some may have suffered from diseases associated with mental retardation. Mohammed advocated feeding and housing those without reason. There is other evidence for favorable attitudes toward the retarded in early history, but attitudes var ied from age to age and from country to country. The concept of remediation did not emerge until the nineteenth century. Earlier, in 1798, ltard published an account of his attempt to train the "wild boy of Aveyron." A rash of efforts to habilitate retarded persons followed. Training schools were developed in Europe and the United States in the 1800s; however, these early schools did not fulfill their promise, and by the end of the nineteenth century large, inhumane warehouses for retarded persons existed. The notion of habilitation through training had largely been abandoned and was not to reappear until after World War II.

Continuing the tradition of excellence established in previous editions, distinguished researcher, practitioner, and educator Alan Kazdin integrates pioneering and recent research with discussions and examples for altering behavior and the conditions that influence their effectiveness. The Seventh Edition reflects several developments within the field of behavior modification, without diminishing an essential emphasis on applied research and intervention techniques. Kazdin has expanded and refined discussions of functional behavioral assessment, antecedent events and their influence on behavior, assessment options, ensuring the quality of assessment, data evaluation, and ethical and legal issues. New to this edition is an Appendix to guide a behavior-change project that focuses on applying the content of the book in everyday life. In addition to comprehensive coverage and lucid explanations of how assessment, evaluation, and intervention work together to improve the care of individuals, the text contains many learning-oriented features, such as chapter outlines that convey content, direction, and key points; practical examples of principles and techniques; an abundant number of tables that summarize important concepts; exercises for designing or evaluating a specific intervention or for changing a program that is not working; and a list of key terms at the end of the chapters. By completing the exercises and understanding the terms, students can master the core content of the chapters. This outstanding text enables students and professionals with varied interests to implement effective techniques with individuals and in contexts where behavior change is desperately neededin a world challenged by a wide range of social problems.

Social problems in many domains, including health, education, social relationships, and the workplace, have their origins in human behavior. The documented links between behavior and social problems have compelled governments and organizations to prioritize and mobilize efforts to develop effective, evidence-based means to promote adaptive behavior change. In recognition of this impetus, The Handbook of Behavior Change provides comprehensive coverage of contemporary theory, research, and practice on behavior change. It summarizes current evidence-based approaches to behavior change in chapters authored by leading theorists, researchers, and practitioners from multiple disciplines, including psychology, sociology, behavioral science, economics, philosophy, and implementation science. It is the go-to resource for researchers, students, practitioners, and policy makers looking for current knowledge on behavior change and guidance on how to develop effective interventions to change behavior.

The Oxford Handbook of Cognitive and Behavioral Therapies provides a contemporary and comprehensive illustration of the wide range of evidence-based psychotherapy tools available to both clinicians and researchers. Chapters are written by the most prominent names in cognitive and behavioral theory, assessment, and treatment, and they provide valuable insights concerning the theory, development, and future directions of cognitive and behavioral interventions. Unlike other handbooks that provide a collection of intervention chapters but do not successfully tie these interventions together, the editors have designed a volume that not only takes the reader through underlying theory and philosophies inherent to a cognitive and behavioral approach, but also includes chapters regarding case formulation, requisite professional cognitive and behavioral competencies, and integration of multiculturalism into clinical practice. The Oxford Handbook of Cognitive and Behavioral Therapies clarifies terms present in the literature regarding cognitive and behavioral interventions and reveals the rich variety, similarities, and differences among the large number of cognitive and behavioral interventions that can be applied individually or combined to improve the lives of patients.

The assessment of criminal behaviours of clients in secure settings poses a number of particular problems; the behaviour in question is neither currently evident, nor can it ethically be elicited therefore recognising it is a complex and important skill. This assessment is used for making critical decisions about a person's liberty and treatment.

Provides a thorough examination of the components of behavior modification, behavior therapy, cognitive behavior therapy, and applied behavior analysis for both child and adult populations in a variety of settings. Although the focus is on technical applications, entries also provide the historical context in which behavior therapists have worked, including research issues and strategies.

Despite the occasional outcries to the contrary, the field of behavior therapy is still growing, and the asymptote has not been reached yet. The umbrella of behavior therapy continues to enlarge and still is able to encompass new theories, new con cepts, new research, new data, and new clinical techniques. Although the number of new behavioral journals now has stabilized, we still see a proliferation of books on the subject. In the past few years, however, we have seen considerable specialization within behavior therapy. No longer is it possible to be a generalist and remain fully abreast of all the relevant developments. Thus, we see behavior therapists who deal with adults, those who deal with children, those whose specialty is hospital psychiatry, and those who see themselves as practitioners of behavioral medicine. Even within a subarea such as behavioral medicine, specialization runs supreme to the extent that there are experts in the specific addictions, adult medical problems, and child medical problems. Given the extent of specialization, there are numerous ways "to skin" the pro verbial "cat." We therefore have chosen to look at the contemporary work in behavior therapy that is being carried out with adults, in part, of course, because of our long-standing interest in this area as teachers, researchers, and clinicians. In so doing, we have chosen to highlight the clinical aspects of the endeavor but not at the expense of the rich research heritage for each of the specific adult disorders.
