A concise description of single-case methodology


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.


  • Offers new options in experimental design, presenting combinations of designs that increase the range of questions that can be asked about alternative interventions
  • Details the underlying rationale and methods of evaluating intervention effects through visual inspection in the area of data evaluation
  • Provides an expanded description of methods (e.g., assessment) and a greater range of examples
  • Includes an appendix at the end of the book to encourage discussion of the challenges, advances, and dilemmas of data evaluation in the design
