Objective: The aim of this study is to review empirical studies that were carried out to evaluate the effectiveness of Cognitive-Behavioral Group Treatment programs for the treatment of schizophrenia and other psychotic disorders.Method: The PsycINFO, PsycARTICLES and MEDLINE databases were searched to identify articles in English that were published between the years of 1980 and 2011 (July) using the following keywords: “(1) psychosis and cognitive treatment (2) schizophrenia and cognitive treatment, (3) schizophrenia and cognitive therapy, (4) psychosis and cognitive therapy, (5) schizophrenia and cognitive intervention (6), psychosis and cogni- tive intervention, (7) hallucination and cognitive therapy, (8) hallucination and cognitive treatment, (9) hallucination and cognitive intervention”. The articles that were identified by these search terms were read and those that were not related to therapy effectiveness and group therapies were eliminated.Results: The remaining 42 studies that satisfied the search criteria were included in this review and were summarized in terms of the methods utilized (characteristics of the study population, measures, randomization, results, follow-up, etc.) and therapy characteristics (number of sessions, frequency of sessions, number of therapists and members, etc.).Conclusion: Taken together, the studies included in this review suggested that cognitive behavioral therapy plus standard treatment given to schizo- phrenic patients and patients with other psychotic disorders is effective in decreasing the symptoms of the disorder (positive and negative symptoms) and/or the problems that accompany the disorder (anxiety, hopelessness etc.).
