"Now in its fifth edition, this classic text helps readers learn how to design, conduct, analyze, and report high-quality clinical studies"-- Provided by publisher.

Alan Kazdin, a well-known and highly respected researcher in behavior modification, offers a scholarly, thoroughly contemporary look at behavior modification principles and their application in clinical, home, school, and work settings. By including both applied research and clinical intervention techniques, Kazdin's text provides a balance between research and practice. The new edition is now written in a more conversational style and offers an expanded "how to" focus, giving students opportunities to practice the principles.

Single-case research has played an important role in developing and evaluating interventions that are designed to alter a particular facet of human functioning. Now thoroughly updated in its second edition, acclaimed author Alan E. Kazdin's Single-Case Research Designs provides a notable contrast to the quantitative methodology approach that pervades the biological and social sciences. While focusing on widely applicable methodologies for evaluating interventions--such as treatment or psychotherapy using applied behavior analysis--this revised edition also encompasses a broader range of research areas that utilize single-case designs, demonstrating the pertinence of this methodology in various disciplines, from psychology and medicine to business and industry. This well-written, clear, and thoroughly updated text is ideal for practitioners, instructors, and students alike.

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.
