Objectives : Deficits in functional outcome are marked in schizophrenia. Recently, social cognition has been identified as a contributor to functional outcome. The purpose of this study is to identify the relationship among psychopathology, social cognition and neurocognition with functional outcome in schizophrenia.
Methods : Participants were twenty-six inpatients fulfilling criteria for schizophrenia according to Diagnostic and Statistical Manual of Mental disorders-Fourth Edition-Text Revision (DSM-IV-TR). We administered ¡®First-order and second-order false belief tasks and Strange story¡¯ for social cognition, ¡®Seoul Computerized Neurocognitive Test (SCNT)¡¯ for neurocognition, ¡®Positive and Negative Syndrome Scale (PANSS)¡¯ for psychopathology, ¡®the Korean Version of 4th Revision of Schizophrenia Quality of life Scale (SQLS-R4K)¡¯ for functional outcome.
Results : We identified that the reaction time and errors of trail making test significantly predicted second-order Theory of Mind (ToM) (p£¼.01). ¡®Trials to Complete 1st Categories¡¯ (p£¼.05) of Wisconsin card sorting test, ¡®second false belief¡¯ (p£¼.05) of social cognition, ¡®depression/anxiety factor¡¯ (p£¼.05) of PANSS predicted quality of life in schizophrenia. Finally, we found that the higher depression/anxiety factor¡¯ the lower quality of life was observed among patients who understood ¡®second false belief¡¯ to a greater extent.
Conclusion : In summary, our results support the importance of social cognition, depression and anxiety symptoms in quality of life in schizophrenia. the results of this study suggest that social cognition acts as a moderator between psychopathology and quality of life.
