What are the components of CBT for psychosis? a delphi study

There is strong evidence supporting the implementation of cognitive behavior therapy (CBT) for people with psychosis. However, there are a variety of approaches to the delivery and conceptual underpinnings within different research groups, and the degree of consensus or disagreement regarding what are the intrinsic components has not been explored. This study uses the Delphi method to try to establish what a group of experts in CBT for psychosis view as important. Experts were invited to participate in 3 rounds of producing and rating statements that addressed areas such as principles, assessment, models, formulation, change strategies, homework, and therapists' assumptions in order to consolidate consensus of opinion. Seventy-seven items were endorsed as important or essential for CBT for psychosis by >80% of the panel. These recommendations should ensure greater fidelity in clinical practice, allow greater evaluation of adherence within clinical trials, facilitate the development of competency frameworks, and be of value in relation to training and dissemination of CBT for psychosis.
