The cognitive behavioural analysis system of psychotherapy: a new psychotherapy for chronic depression

Abstract

The cognitive behavioural analysis system of psychotherapy (CBASP) is a new therapy specifically designed to treat chronic depression. Conceptually the bio-psychosocial signs and symptoms of chronic depression are viewed as the result of either arrested maturational development at a Piagetian preoperational stage (in early-onset patients) or heightened emotionality and general functional regression (in late-onset patients). In this therapy, patients learn how their cognitive and behavioural patterns produce and perpetuate interpersonal problems and how to alter maladaptive patterns of interpersonal behaviour. The focus is primarily on interpersonal interactions, including with the therapist, through the latter's disciplined personal involvement. In this article we outline the therapy process and key mechanisms of change using examples to illustrate specific techniques. We also outline the theoretical model underpinning CBASP and summarise the evidence from a large clinical trial.
