【摘要】 目的 编制糖尿病患者运动自我管理行为量表并行信效度检验，为临床开展糖尿病患者运动自我管理行为评价提供测量工具。方法 采用文献研究、半结构化访谈和专家函询法，构建糖尿病患者运动自我管理行为量表条目池。通过预调查拟定糖尿病患者运动自我管理行为初始量表，采用便利抽样法选取120例2型糖尿病患者进行项目分析、Cronbach’s α系数、重测信度、折半信度、内容效度和探索性因子分析，另选取200例2型糖尿病患者进行验证性因子分析、聚合效度和区分效度分析。结果 编制的糖尿病患者运动自我管理行为量表含运动评估与准备、运动实施与监测、运动评价与支持3个维度，共18个条目，Cronbach’s α系数为0.887,重测信度为0.995,折半信度为0.903。3个维度与总量表的相关系数为0.669～0.945(P<0.01),条目水平的内容效度指数为0.833～1.000,量表整体内容效度指数为0.944。探索性因子分析产生3个公因子，累计方差贡献率69.23%;验证性因子分析卡方自由度比为1.866,标准拟合指数为0.818,非规准适配指数为0.885,拟合优度指数为0.809,增值拟合指数为0.907,比较拟合指数为0.905,近似误差均方根为0.094,模型拟合效果良好，聚合效度和区分效度良好。结论 糖尿病患者运动自我管理行为量表结构合理、内容全面、表述清晰、信效度良好，为调查糖尿病患者的运动自我管理行为提供了一个适当的工具。更多还原

【Abstract】 Objective To prepare the self-management behavior scale on exercise for patients with diabetes mellitus and test its reliability and validity, so as to provide a measuring tool for clinical evaluation of self-management behavior on exercise in patients with diabetes mellitus. Methods With literature review, semi-structured interviews, and expert consultation, an item pool of self-management behavior scale on exercise for patients with diabetes mellitus was developed. The initial self-management behavior scale on exercise for patients with diabetes mellitus was proposed through pre-investigation. Using a convenience sampling method, a total of 120 patients with type 2 diabetes mellitus were selected for item analysis, Cronbach’s α coefficient, test-retest reliability, split-half reliability, content validity, and exploratory factor analysis. Another 200 patients with type 2 diabetes mellitus were selected for confirmatory factor analysis, convergent validity, and discrimination validity assessments. Results The prepared self-management behavior scale on exercise for patients with diabetes mellitus included three dimensions: exercise assessment and preparation, exercise implementation and monitoring, and exercise evaluation and support. It consisted of 18 items, with a Cronbach’s α coefficient of 0.887, test-retest reliability of 0.995, and split-half reliability of 0.903. The coefficients of correlation between the three dimensions and the overall scale were 0.669-0.945(P<0.01). The content validity indices for individual items were 0.833-1.000, and the overall content validity index of the scale was 0.944. Exploratory factor analysis generated 3 common factors with a cumulative variance contribution rate of 69.23%. Confirmatory factor analysis showed a χ~2/df of 1.866, a normed fit index of 0.818, a Tucker-Lewis index of 0.885, a goodness-of-fit index of 0.809, an incremental fit index of 0.907, a comparative fit index of 0.905, and a root mean square error of approximation of 0.094, indicating good model fit, as well as satisfactory convergent and discriminant validity. Conclusion The self-management behavior scale on exercise for patients with diabetes mellitus has a reasonable structure, comprehensive content, clear expression, good reliability and validity, which provides an appropriate tool for investigating the self-management behavior on exercise of patients with diabetes mellitus.更多还原
