The aim of this study was to examine the validity and reliability of the Persian version of the Short Form Self-Regulation Questionnaire (SSRQ) among Iranian community-dwelling older adults and to determine its optimal cutoff point. In Shiraz, Iran, a cross-sectional study of 500 older adults ≥ 60 years was conducted in two steps. The forward-backward method was used for translation. Psychometric properties, such as the face and content validity, based on the point of view of experts, construct validity based on exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), convergent validity by assessing the relationship with the Generalized Self-Efficacy Scale (GSE-10), and reliability based on Cronbach's α were examined. A receiver operating characteristic curve (ROC) was plotted to confirm the cutoff point. Validity of both the face and the content was confirmed. The first stage of construct validity was performed using the kurtosis test and the EFA, and finally, only 20 items in four subscales were loaded with 76.34% of the total variance. The CFA indicated a good fit to the data (root mean square error of approximation (RMSEA) = 0.059; comparative fit index (CFI) = 0.92; and goodness of fit index (GFI) = 0.89). Cronbach's α coefficient of the SSRQ-20 increased to 0.87. A significant positive correlation was found between the SSRQ-20 and the GSE-10 ( = 0.44), indicating acceptable convergent validity. The optimal cutoff score for differentiating older adults in terms of self-regulation was 71. This study demonstrates that the Persian version of the SSRQ, which contains 20 items, is a valid and reliable tool for assessing self-regulation in Iranian community-dwelling older adults.
本研究旨在检验波斯语版简短自我调节问卷（SSRQ）在伊朗社区居住老年人中的有效性和可靠性，并确定其最佳截断点。在伊朗设拉子，对500名60岁及以上的老年人进行了一项分两步进行的横断面研究。采用前后翻译法进行翻译。基于专家视角检验了心理测量学特性，如表面效度和内容效度，基于探索性因子分析（EFA）和验证性因子分析（CFA）的结构效度，通过评估与一般自我效能量表（GSE-10）的关系检验收敛效度，以及基于克朗巴哈α系数检验信度。绘制了受试者工作特征曲线（ROC）以确定截断点。表面效度和内容效度均得到证实。使用峰度检验和EFA进行结构效度的第一阶段分析，最终，四个子量表中的仅20个项目负荷了总方差的76.34%。CFA表明数据拟合良好（近似均方根误差（RMSEA）=0.059；比较拟合指数（CFI）=0.92；拟合优度指数（GFI）=0.89）。SSRQ-20的克朗巴哈α系数增至0.87。SSRQ-20与GSE-10之间存在显著正相关（=0.44），表明收敛效度可接受。区分老年人自我调节能力的最佳截断分数为71。本研究表明，包含20个项目的波斯语版SSRQ是评估伊朗社区居住老年人自我调节能力的有效且可靠工具。
