The promise of cognitive behavior therapy for treatment of severe mental disorders: a review of recent developments.

Cognitive behavior therapy (CBT), as exemplified by the model of psychotherapy developed and refined over the past 40 years by A.T. Beck and colleagues, is one of the treatments of first choice for ambulatory depressive and anxiety disorders. Over the past several decades, there have been vigorous efforts to adapt CBT for treatment of more severe mental disorders, including schizophrenia and the more chronic and/or treatment refractory mood disorders. These efforts have primarily studied CBT as an adjunctive therapy, i.e., in combination with pharmacotherapy. Given the several limitations of state-of-the-art pharmacotherapies for these severe mental disorders, demonstration of clinically meaningful additive effects for CBT would have important implications for improving public health. This paper reviews the key developments in this important area of therapeutics, providing a summary of the current state of the art and suggesting directions for future research.
