腰椎间盘突出症患者中医康复健康信息获取行为量表的编制及信效度检验

Development of TCM Rehabilitation Health Information Seeking Behavior Scale for patients with lumbar disc herniation and its reliability and validity

目的 编制腰椎间盘突出症患者中医康复健康信息获取行为量表,并检验其信效度。方法 以Wilson信息行为模型为指导,通过文献分析法、半结构访谈、2轮Delphi专家函询及预调查形成量表施测稿。对432例腰椎间盘突出症患者进行问卷调查,检验量表的信效度。结果 腰椎间盘突出症患者中医康复健康信息获取行为量表包括中医康复健康信息需求、中医康复健康信息来源和中医康复健康信息获取障碍3个维度,共30个条目,累计方差贡献率为64.912%。总量表的内容效度指数为0.969,Cronbach α系数为0.914,重测信度为0.836,分半信度为0.853,验证性因子分析结果显示该量表结构效度良好。结论 腰椎间盘突出症患者中医康复健康信息获取行为量表信效度良好,可作为评估腰椎间盘突出症患者中医康复健康信息获取行为水平的有效工具。

Objective To develop a TCM Rehabilitation Health Information Seeking Behavior Scale for Patients with Lumbar Disc Herniation,and to test its reliability and validity.Methods Guided by Wilson’s model of information behavior,a draft of the scale was developed through literature review,semi-structured interview,two-round of Delphi expert consultation and pre-investigation.A total of 432 patients with lumbar disc herniation were surveyed to test the reliability and validity of the scale.Results The final scale was composed of 3 dimensions of TCM rehabilitation health information needs,health information sources and health information acquisition barriers and 30 items,and it could explain 64.912%of the total variance.The content validity index at the scale level was 0.969;Cronbach’sαcoefficient was 0.914;the retest reliability was 0.836,and the split-half reliability was 0.853.Confirmatory factor analysis showed that the scale had good construction validity.Conclusion The TCM Rehabilitation Health Information Seeking Behavior Scale for Patients with Lumbar Disc Herniation in this study has good reliability and validity,which can be used as an effective measurement tool to assess TCM rehabilitation health information seeking behavior in patients with lumbar disc herniation.
