Integrating approaches to psychotherapy in psychosis*.

Objective: The evidence base for specific psychological treatments for psychosis is now well established, but many practitioners see themselves as integrationist in approach. The basic tenets of integration are explored with an emphasis on understanding how different levels of need can be conceptualized and then used to 'adapt' a treatment to meet those needs in an individual. The needs are then incorporated into an integrated treatment formulation.

Method: The evidence base is strongest for cognitive behavioural and family approaches, but the present paper summarizes concepts from two specific models of therapy that are intrinsically integrational in their approach: cognitive analytic therapy and psychodynamic interpersonal therapy.

Results: Both approaches show aspects of integration. However, following this approach to integration to its limit would ultimately lead to one undifferentiated therapy.

Conclusions: Both approaches share a common set of values of developing specific ways of increasing collaboration and working together, and these values are shown to underpin adaptive ways of working with psychosis, but further critical analysis of the development of integrative models is needed.
