Behavioral experiments are one of the central and most powerful methods of intervention in cognitive therapy. Yet until now, there has been no volume to guide clinicians wishing to design and implement behavioral experiments. Behavioural Experiments in Cognitive Therapy fills this gap. It is written by clinicans for clinicians. It is a practical, easy to read handbook, which is relevant for practicing clinicians at every level, from trainees to cognitive therapy supervisors.Following an introduction by David Clark, the first two chapters provide a theoretical and practical background for the understanding and development of behavioral experiments. Therafter, the remaining chapters of the book focus on particular problem areas. These include problems which have been the traditional focus of cognitive therapy, such as depression and anxiety disorders, as well as those which have only once more recently become a subject of study, such as bipolar disorder and psychotic symptoms. Additionally, it includes some which are still int their relative infancy--physical health problems, and brain injury.The book includes several chapters on transdiagnostic problems, such as avoidance of affect, low self-esteem, interpersonal issues, and self-injurious behavior. A final chapter by Christine Padesky provides some signposts for future development. Containing examples of over 200 behavioral experiments, this book will be of enormous practical value for all those involved in cognitive behavioral therapy, as well as stimulting exploration in both its readers and their patients.
