摘要
目的开发血液透析患者自我管理行为问卷,并进行信度和效度检验。方法在血液透析患者自我管理行为概念的基础上作成问卷。5名透析护士和10名血液透析患者分别评价问卷的内容效度和表面效度。问卷包含4个下位尺度59个项目,5个透析中心的120名患者参加了调查。结果有效问卷107份。主因子分析并正交旋转抽出4个因子,确定25个项目。问卷的结构与设计时的构想基本吻合。内部一致性信度Cronbach’sα系数为0·814。效标关联效度检验每日体重增加值与自我管理行为负相关,与液体、离子的限制行为和饮食量的管理行为显著负相关。结论此问卷有较好的信度和效度,为研究者提供了透析患者自我管理行为评估和干涉的工具。
Objective To develop a self-management behavior scale for hemodialysis patients, and verify its reliability and validity. Methods Scale was made based on the definition of hemodialysis patients＇ selfmanagement behavior. After 5 dialysis nurses and 10 hemodialysis patients performing to establish content validity and face validity, 4 sub-scales constructed with 59 items＇ scale was used to measure self-management behavior of 120 hemodialysis patients in 5 dialysis centers. Results one hundred and seven questionnaires were available. Four factors were extracted by using principal factor analysis and varimax rotation, and 25 items were selected. The structure of the scale was basically based on the initial designed structure. The internal consistency was supported by Cronbach＇ s alpha coefficient of 0.814. Testing of criterion-related validity found daily weight gain was negatively associated with self-management behavior and significandy negatively associated with the behavior of restriction of liquid, ion and management behavior in quantity of food. Conclusion the serf-management behavior scale is reliable, valid and practical. It provides a tool for researchers to evaluate the outcome of management programs that target to improve patients＇ self-management practices.
