The study aimed at testing the validity and reliability of the Persian version of the treatment self-regulation questionnaire (TSRQ-15) across healthy diet, exercise and medication-use/glucose-monitoring among Iranian people with type-2 diabetes.
Cross-sectional design.
Content validity was investigated by 16 experts. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed. Construct validity, convergent/discriminant validity and internal consistency were examined. Concurrent validity was assessed using Spearman's rho correlation across different behaviours.
Content validity was confirmed for Persian TSRQ-15. A three-factor structure was revealed, in which external regulation and introjected regulations were validated, while amotivation and autonomous failed to show discriminant validity. Internal consistency was sound, and concurrent validity was approved. The Persian version of TSRQ-15 was shown to be a valid and reliable tool for assessing motivation behind the practice of healthy diet, exercise and medication-use/glucose-monitoring in people with type 2 diabetes.
本研究旨在检验治疗自我调节问卷(TSRQ-15)波斯语版本在伊朗 2 型糖尿病患者健康饮食、运动和药物使用/血糖监测方面的有效性和可靠性。
横断面设计。
通过 16 名专家评估内容效度。采用探索性因子分析(EFA)和验证性因子分析(CFA)。检验结构效度、聚合/区别效度和内部一致性。通过不同行为的 Spearman rho 相关评估同时效度。
波斯语 TSRQ-15 的内容效度得到确认。揭示了一个三因素结构,其中外部调节和内化调节得到验证,而动机缺乏和自主则未能表现出区别效度。内部一致性良好,同时效度得到认可。波斯语 TSRQ-15 是一种有效且可靠的工具,可用于评估 2 型糖尿病患者健康饮食、运动和药物使用/血糖监测行为背后的动机。
