Abstract
The aim of this meta-analysis was to assess the effectiveness of cognitive behavioural therapy (CBT) in reducing negative symptoms in patients with schizophrenia. The search period was from the beginning of the database creation to 30 September 2022. An initial search of 169 articles was conducted through database searches and other means. After applying inclusion and exclusion criteria, seven randomised controlled studies were included in the final analysis. The intervention group included a total of 293 patients with schizophrenia, and the control group included 291 patients with schizophrenia. Meta-analysis showed that there was a statistically significant difference in negative symptom reduction between the CBT intervention group [SMD = −0.26,95% CI (−0.45, −0.07), p = 0.006] and the control group. We analysed the effectiveness of CBT based on previous studies and found that CBT was effective in improving negative symptoms in patients with schizophrenia.

The International Journal of Psychology (IJP) is the journal of the International Union of Psychological Science (IUPsyS) and is published under the auspices of the Union. IJP seeks to support the IUPsyS in fostering the development of international psychological science. It aims to strengthen the dialog within psychology around the world and to facilitate communication among different areas of psychology and among psychologists from different cultural backgrounds. IJP is the outlet for empirical basic and applied studies and for reviews that either (a) incorporate perspectives from different areas or domains within psychology or across different disciplines, (b) test the culture-dependent validity of psychological theories, or (c) integrate literature from different regions in the world.
