In this successful text, Dr. Alan Kazdin describes research methods in psychology and provides criteria for conducting and evaluating clinical research. Unlike its competitors, the emphasis is on clinical psychology, but the issues and methods are relevant to counseling, education, school psychology, psychiatry, and social work. Also, the various stages of research are covered, with an emphasis on the special demands that are placed on the investigator. Research Design in Clinical Psychology, Third Edition continues to explain how methodology is an approach toward problem solving, thinking, and acquiring knowledge. This revised edition includes three new chapters which reflect the evolving nature of methodology and the proliferation of clinical research into many topic areas. In essence, students and clinicians will have a thorough knowledge of the entire research process from developing the idea, selecting methods, analyzing the results, and preparing the written scientific report.
