Purpose:This study was conducted to provide a systematic review of the evidence from controlled trials regarding social cognition interventions for patients with schizophrenia, a discussion of the methodological problems that limit current research, and suggestions regarding future directions for research. Methods: Using a predefined protocol, six electronic data bases were searched, studies selected, relevant data extracted and the methodological quality of the studies assessed. Results: Eight papers were found reporting on complex, generally heterogeneous interventions. Studies report positive results, including improvements in emotion cognition, theory of mind, and social perception, etc. There were six randomized controlled trials and two quasi-experimental studies. Five studies were based on theoretical background such as informational process theory, Frith's model, neurodevelopmental theory, systematic model, and social cognitive model. Contents of social cognitive interventions were 'theory of mind (TOM)', 'emotion recognition,' 'social context perception,' and combined neurocognitive intervention.' Those interventions had an effect on factors of social cognition and neurocognition generally. Conclusion: The review demonstrated that a great deal is known about the sources of social cognition, the impact on a range of outcomes and methodology. Although some useful evidence was reported for all interventions, further research needs to be carried out.
