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 beneits 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 signiicant 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. Keywords: Cognitive behavioral therapy for psychosis; Schizophrenia; Depressive symptoms; Psychosis; Depression in the UK and the United States [6-8]. here is evidence from meta analyses too, that it is efective; for example [3]. his review reported overall beneicial efects of the target symptom 0.40 (95% CI= 0.252, 0.548) from 33 studies. he same meta analysis reported an efect size of 0.363 [95% CI=0.079, 0.647] for its efect on depressive symptoms, on the basis of 15 studies. his latter inding has an intuitive appeal, in that CBT was originally developed for depressive symptoms, and both CBT for anxiety and depression and the CBT for psychosis use broadly similar principles. It is therefore important to examine this efect of CBTp on depressive symptoms. he aim of the current article is to investigate the number of studies that include or address changes in depressive symptoms in the course of CBT treatment for psychosis. Methods Searched source On March, 10, 2015, we searched the Embase, Medline, Current Contents, Web of Science, PsychInfo, and the Cochrane Collaborative Register of Trials. Additionally we hand searched grey literature, and cotacted leaders in the ield. Search strategy We performed our search using the following search terms either as key terms or as key words: (SCHIZO* or SCHIZOPHRENIA or SCHIZOAFFECTIVE DISORDER) AND (COGNITIVE THERAPY or COGNITIVE BEHAVIOUR THERAPY or COGNITIVE BEHAVIOR THERAPY) AND (RANDOM or RANDOMISED CONTROL TRIAL or CLINICAL TRIAL). Background Approximately one third of those diagnosed with schizophrenia have concurrent depression, with these prevalence rates remaining highly consistent over time, study population, phase of the illness, and measures of depression. Comorbid depression has a considerable impact on the diagnosis, progression, and treatment of schizophrenia [1,2]. Depressive symptoms are associated with considerable long- term hindrance on the treatment of schizophrenia; those with depressive symptoms are more likely to use relapse-related mental health services, have poor social and family relationships, pose a greater danger to self and others, and have a lower quality of life, motivation, mental and physical health, lower level of functioning, and lower level of medication adherence [1,2]. Since the 1980s, Cognitive Behavioural herapy (CBT) has been used as a method of treatment for afective disorders and has been integrated into common practice [3]. CBT was initially developed based on Beck’s priniciples of cognitive therapy for depression [4]. Although, Beck described use of CBT for psychosis [5], the irst controlled studies on Cognitive Behaviour herapy For Psychosis (CBTp) emerged in the early 1990s in the United Kingdom, and this treatment has developed and included some of the theoretical underpinnings of CBT from other disorders. he irst controlled studies on Cognitive Behaviour herapy For Psychosis (CBTp) emerged in the early 1990s in the United Kingdom, and this treatment has developed and included some of the theoretical underpinnings of CBT from other disorders. Reviews of studies of CBTp have suggested that they are useful for the treatment of schizophrenia, and CBT for psychosis is now recognised as an intervention for schizophrenia in clinical guidelines Research Article Effect of Cognitive Behaviour Therapy for Psychosis (Cbtp) on Depressive Symptoms: A Review of Literature Taalman HC 1 , Goldberg DM 1 , Ayub M 1 , Munshi T 1 , Rathod S 2 , Farooq S 3 and Naeem F 1 * 1 Queens University, Kingston, Canada 2 Southampton University, Southampton, UK 3 Staffordshire University, Staffordshire, UK *Corresponding author: Naeem F, Queens University, Kingston, Canada Received: November 09, 2015; Accepted: November 27, 2015; Published: November 30, 2015
