To evaluate the structural validity of the Rheumatology Attitudes Index (RAI), a widely used measure of rheumatic disease-related helplessness in patients with systemic sclerosis (SSc).
Patients with physician-confirmed SSc from the University of California, Los Angeles (UCLA) Scleroderma Quality of Life Study (n = 208) received clinical examinations and completed self-report questionnaires. The structural validity of the RAI was examined through confirmatory and exploratory factor analysis (CFA/EFA).
A tenable factor structure was not identified through CFA or EFA.
The present structural analysis did not support the use of the RAI with SSc patients.
评估风湿态度指数（RAI）的结构效度，该指数是广泛用于衡量系统性硬化症（SSc）患者风湿疾病相关无助感的指标。
来自加利福尼亚大学洛杉矶分校（UCLA）硬皮病生活质量研究中经医生确诊为SSc的患者（n = 208）接受了临床检查并完成了自我报告问卷。通过验证性和探索性因素分析（CFA/EFA）检验RAI的结构效度。
通过CFA或EFA未确定合理的因素结构。
目前的结构分析不支持将RAI用于SSc患者。
