Abstract
INTRODUCTION: This study was designed to determine the reliability and validity of the Chinese version of the Personal and Social Performance scale (PSP-CHN) and assess the applicability of using the PSP-CHN in patients with severe mental disorders. METHODS: A total of 285 outpatients with severe mental disorders, 220 with schizophrenia and 65 with major depressive disorder, were enrolled into the study. Both diagnoses were made using the DSM-IV. All the patients were assessed with the PSP-CHN, the GAF, and the CGI-S. In addition, the PANSS and the MADRS were used to assess the patients with schizophrenia and major depressive disorder, respectively. RESULTS: The PSP-CHN showed good internal consistency (Cronbach α = 0.839, n = 285), high interrater reliability for total scores (intraclass correlation coefficient, ICC = 0.865, n = 48), and good test-retest reliability (ICC = 0.892, n = 130). The PSP-CHN total score showed a statistically significant positive correlation with the GAF score (r = 0.927, P < .01, n = 285), as well as a significant negative correlation with the CGI-S total score (r = -0.793, P < .01, n = 285), the PANSS total score (r = -0.694, P < .01, n = 220), and the MADRS total score (r = -0.721, P < .01, n = 65). DISCUSSION: We were able to demonstrate that the PSP-CHN is a reliable and valid measurement tool to assess the personal and social functioning in patients with severe mental disorders.
