RESUMEN
OBJECTIVE: To identify predictive factors associated with the improvement of social functioning of schizophrenia patients in a community. METHODS: 101 schizophrenia patients undergoing community rehabilitation were assessed with the Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance Scale (PSP), Self-Esteem Scale (SES), Family Function Questionnaire (APGAR), and the World Health Organization Disability Assessment Scale II (WHODAS-II) twice 6 months apart. Pearson correlation and hierarchical multiple linear regression analyses were performed to identify the influencing and predictive factors associated with the improvement of social functioning. RESULTS: The increase of PSP score was correlated with age (r = 0.220), reduced PANSS negative score (r = 0.468), reduced PANSS general score (r = 0.392), reduced PANSS total score (r = 0.472), and reduced WHODAS-II Score (r = 0.247). The predictive factors of the change of PSP score followed the following order: change of PANSS negative score [the change of coefficient of determination (deltaR2 ) = 0.197], age of onset (deltaR2 = 0.048), change of WHODAS-II score and psychiatric rehabilitation (deltaR2 = 0.031). CONCLUSION: Improvement of negative symptoms predicts the short-term improvement of social functioning of schizophrenia patients.
