【摘要】目的 构建血液透析患者液体摄入依从动机量表并检测其信效度。方法 以保护动机理 论为基本框架,通过文献分析法、患者访谈法、专家咨询法形成初始版量表。采用便利抽样法,于2019年 4— 7 月,在江苏省内 10 所血液净化中心选取 170 例血液透析患者进行预调查,通过项目分析、探索性 因子分析形成暂定版量表;选取 550 例血液透析患者进行正式施测,评价量表信度和效度。结果 最终 形成的量表包括 22 个条目,探索性因子分析提取 7 个公因子,累积方差贡献率为 75.949%;总量表的 Cronbach's α 系数为 0.928,Spearman-Brown 系数为 0.841,重测信度系数为 0.899;量表的内容效度指数 为 0.987;验证性因子分析模型拟合良好。结论 血液透析患者液体摄入依从动机量表具有良好的信效 度,可用于评估患者液体摄入依从动机。
【摘要】Objective To establish fluid intake compliance motivation scale for hemodialysis patients and to test its reliability and validity. Methods With protection motivation theory as the basic framework, the initial scale was established by means of literature analysis, patient interview and expert consultation. From April 2019 to July 2019, a total of 170 patients with hemodialysis in 10 blood purification center in Jiangsu Province were selected for preliminary investigation by convenient sampling method, and the tentative scale was formed through project analysis and exploratory factor analysis. A total of 550 hemodialysis patients were selected for formal testing to evaluate the reliability and validity of the scale. Results The final scale consisted of 22 items. 7 common factors are extracted by exploratory factor analysis and the cumulative variance contribution rate was 75.949%. The Cronbach's α coefficient of the total scale was 0.928, Spearman-Brown coefficient was 0.841 and the retest reliability coefficient was 0.899. The content validity index of the scale was 0.987. The confirmatory factor analysis model fitted well. Conclusions Fluid intake compliance motivation scale for hemodialysis patients has good reliability and validity, which can be used to assess fluid intake compliance motivation of patients.
