24项康复评估量表（RAS）是衡量精神疾病患者康复的最广泛使用和最有效的工具。本研究旨在评估中国精神分裂症患者的8项简短RAS量表（RAS-8）的信度和效度。招募了400名精神分裂症患者进行规模验证。通过计算Cronbach’s α来检验内部一致性。用总分的类内相关系数（ICC）和每个项目的加权kappa计算重测信度。采用验证性因子分析检验因子结构，并通过调查RAS-8与患者症状、残疾、抑郁、焦虑、患者功能、生活质量和一般健康的相关性来检验并发效度。RAS-8全量表和分量表与Cronbach 's alpha在0.87 ~ 0.92之间具有良好的内部一致性。ICC值为0.99，加权kappa值为0.62 ~ 0.88，总体上表明重测信度较好。结果支持先验双因素结构，χ2/df = 2.93, CFI = 0.98, TLI = 0.98, RMSEA = 0.07, SRMR = 0.035。RAS-8与患者症状（r = - 0.24, p < 0.01）、残疾（r = - 0.30, p < 0.01）、抑郁（r = - 0.16, p < 0.05）和焦虑（r = - 0.14, p < 0.05）呈显著负相关，与患者功能（r = 0.26, p < 0.01）、生活质量（r = 0.39, p < 0.01）和总体健康（r = 0.34, p < 0.01）呈显著正相关，进一步支持了RAS-8的并发效度。本研究证实了8项简短RAS量表对中国社区精神分裂症患者的信度和效度。RAS-8的验证允许其作为完整RAS的替代方案，作为临床和研究环境中的快速评估工具。讨论了研究结果对其他人群和其他国家的应用和验证的影响。
The 24-item Recovery Assessment Scale (RAS) is the most widely-used and well-validated tool for measuring recovery for people with mental illness. The current study aims to assess the reliability and validity of an 8-item short form of RAS (RAS-8) among a Chinese sample of people living with schizophrenia. A sample of 400 people living with schizophrenia were recruited for scale validation. Internal consistency was tested by calculating Cronbach's α. Test–retest reliability was calculated using the intraclass correlation coefficient (ICC) for the total score and weighted kappa for each item. Factor structure was tested with confirmatory factor analysis, and concurrent validity was examined by investigating the correlation of the RAS-8 with patient symptoms, disability, depression, anxiety, patient functioning, quality of life and general health. The RAS-8 full scale and subscales showed good internal consistency with Cronbach’s alpha ranging from 0.87 to 0.92. ICC of 0.99 and weighted kappa ranged from 0.62 to 0.88, which generally indicates good test–retest reliability. The findings supported an a priori two-factor structure, χ2/df = 2.93, CFI = 0.98, TLI = 0.98, RMSEA = 0.07, SRMR = 0.035. Concurrent validity of the RAS-8 was further supported by its significant negative correlations with patient symptoms (r = −0.24, p < 0.01), disability (r = −0.30, p < 0.01), depression (r = −0.16, p < 0.05), and anxiety (r = −0.14, p < 0.05), and its significant positive relationships with patient functioning (r = 0.26, p < 0.01), quality of life (r = 0.39, p < 0.01) and general health (r = 0.34, p < 0.01). This study confirmed the reliability and validity of an 8-item short-form RAS for people living with schizophrenia in Chinese communities. The validation of the RAS-8 allows for its use as an alternative for the full RAS as a rapid assessment tool in clinical and research settings. The findings are discussed for their implications for application and validation with other populations and in other countries.
