The Personal and Social Performance Scale (PSP) is a 100-point single-item rating scale that assesses four important domains of patients with mental disorders. This study was designed to examine the validity and reliability of a Chinese version of the PSP. The study was conducted in a sample of 157 patients with schizophrenia (confirmed by DSM-IV-TR criteria, SCID-P interview). The internal consistency (Cronbach's alpha=0.84) and the inter-rater reliability (kappa value=0.82, ICC=0.94 for PSP total score) was good. The test-retest reliability was high (intraclass correlation coefficient (ICC) of 0.95). The scale showed good construct validity with statistically significant correlations with the Global Assessment of Functioning Scale (GAF) (ICC of 0.95). The PSP score had a good negative correlation with the Positive and Negative Syndrome Scale (PANSS) total score. The improvement in PSP after 8 weeks of treatment was significantly correlated with the reduction in PANSS: after 8 weeks of treatment, the responders (defined as those with a reduction in PANSS total score ≥50%) experienced a greater improvement in PSP than the non-responders. The Chinese version of the PSP is a convenient and valid instrument to assess the personal and social functions of stabilized and acute patients with schizophrenia.
个人和社会功能量表（PSP）是一个 100 分的单项评定量表，用于评估精神障碍患者的四个重要领域。本研究旨在检验 PSP 中文版的效度和信度。研究对象为 157 名精神分裂症患者（DSM-IV-TR 标准确诊，SCID-P 访谈）。该量表具有良好的内部一致性（克朗巴赫系数为 0.84）和评分者间信度（kappa 值为 0.82，PSP 总分的 ICC 值为 0.94）。重测信度也较高（ICC 为 0.95）。该量表与总体功能评估量表（GAF）具有良好的结构效度（ICC 为 0.95），与阳性和阴性症状量表（PANSS）总分呈显著负相关。治疗 8 周后 PSP 的改善与 PANSS 总分的降低显著相关：治疗 8 周后，PANSS 总分降低≥50%的缓解者与未缓解者相比，PSP 改善更明显。PSP 中文版是一种评估稳定期和急性期精神分裂症患者个人和社会功能的简便、有效的工具。
