Single Case Experimental Designs provides a clear and comprehensive introduction to the use of single case experimental designs.  Single case experiments are a flexible and efficient type of research design that can be easily learned and used in both scientific and practical settings to make causal inferences about the relations between an intervention or manipulation and change in the individual.    The purpose of this book is to provide a comprehensive sourcebook on single case experimental designs with practical guidelines for their use in a range of research and clinical settings.  It is suitable for use as a textbook for a course on research methodology or clinical assessment and treatment, or as a desk reference for seasoned researchers and practicing clinicians.   Written in a non-technical style, this book is designed to be accessible to individuals from a range of backgrounds including advanced undergraduates, graduate students, researchers, and mental health practitioners–and to those working from a wide range of perspectives, including clinical psychology, educational or school psychology, social work, psychiatry, nursing, and other fields focused on human behavior change.
