Effect of Cognitive Behaviour Therapy for Psychosis (CBTp) on Depressive Symptoms: A Review of Literature

Objective: There is evidence from the literature that Cognitive Behavioral Therapy for psychosis (CBTp) might have a positive effect on depressive symptoms. The aim of this paper is to examine how treatment using CBTp for patients experiencing psychosis effects depressive symptoms associated with schizophrenia. Methods: 17 trials of CBTp that reported depressive symptoms were selected for this literature review. Results: Six out of 17 trials reported benefits for the depressive symptoms. In 3 of these trials CBT for anxiety and low self esteem was used that did not target psychotic symptoms as primary targets. In two trials effects on depression became statistically significant at followup only. Conclusion: CBTp can reduce depressive symptoms in patients with schizophrenia. However, there is a need for improving reporting of these symptoms in future studies
