Construction and reliability and validity test of knowledge,attitude and practice questionnaire on Helicobacter pylori infection in physical examination population

目的编制体检人群幽门螺杆菌感染知信行问卷,并进行信效度验证。方法本研究为横断面调查。依据知信行理论框架,通过回顾性文献研究、质性访谈、课题组讨论等方法自行设计体检人群幽门螺杆菌感染知信行问卷初稿,通过专家咨询法(Delphi法)对问卷的结构和条目进行咨询修订;2021年5—6月对华东疗养院体检中心的186名体检人员进行调查,经问卷信效度调整和验证,形成"体检人群幽门螺杆菌感染知信行问卷"终稿。结果形成的体检人群幽门螺杆菌感染知信行问卷包含3个维度、28个条目,累计方差贡献率为56.271%。问卷I-CVI为0.75~1.00,S-CVI为0.94。问卷知识、态度、行为维度Cronbachα系数分别为0.862、0.901、0.798。问卷总体Cronbachα系数为0.890,折半信度为0.698。问卷的重测信度为0.919,各维度重测信度为0.924、0.917、0.845。结论体检人群幽门螺杆菌感染知信行问卷具有良好的信效度,可用于体检人群幽门螺杆菌感染知信行水平的测定。
