Cognitive Behavioral Therapy for Psychosis

Abstract

Cognitive behavioral therapy for psychosis (CBTp) is recommended by the National Treatment Guidelines in both the U.K. and the U.S. Consistent reports of moderate effect sizes have led to such interventions being suggested as part of routine clinical practice. However. Access to CBTp is poor due to a variety of factors, including training and resources. Therapeutic developments should be based on the theoretical understanding of cognitive models and psychological process associated with stress-vulnerability model. Cognitive models of psychosis incorporate the role of negative core beliefs, hypervigilance for threat, scanning for confirmatory evidence and safety behavior. The current evidence about CBTp is reviewed regarding various methods such as low-intensity of CBTp, different formats of therapy (e.g., individual or group), and phase of illness (e.g., acute or treatment-resistant) of subjects. This review suggests that that patients with psychosis with various disease phase need to be derived more benefit from appropriate adjunctive CBTp.
