Cognitive behaviour therapy for psychosis
This chapter outlines current cognitive behaviour therapy approaches for positive psychotic symptoms and their theoretical underpinnings. The difficulties of translating research into frontline practice are examined, with recommendations for effective implementation. Evidence for the effectiveness of cognitive behaviour therapy for psychosis (CBTp) is reviewed, identifying challenges in the design, conduct, and interpretation of evaluations. New developments are highlighted, including specific interventions designed to target single psychological processes hypothesized to cause or maintain distressing psychotic symptoms. The current evidence for CBTp specifically for those with persisting and distressing positive symptoms of psychosis, who either do not respond to medication or have chosen not to take medication, is outlined. Finally, predictors of good outcome in CBTp are presented.
