Psychopathology, cognitive function, and social functioning of patients with schizophrenia.

OBJECTIVES. To explore the relationship between cognitive functions, social functioning, and psychopathology in schizophrenia. METHODS. Patients diagnosed with schizophrenia, according to the ICD-10 criteria, were enrolled from the Department of Psychiatry of 2 postgraduate hospitals in Kolkata, India. The Positive and Negative Syndrome Scale for Schizophrenia, Schizophrenia Research Foundation India-Social Functioning Index, and a cognitive test battery were administered. RESULTS. Regarding the 100 patients recruited into the study, 4 subtests (self-care, occupational role, social role, and family role) of the social functioning were found to be significantly correlated with cognitive functions. Cognitive function battery performance scores were more inversely correlated with negative symptoms than with positive symptoms. CONCLUSION. Positive and negative symptoms along with verbal fluency were able to predict social functioning.
