摘要
目的 编制炎症性肠病(IBD)患者菌群移植知信行量表,并对其进行信效度检验.方法 以知信行理论为指导,通过文献回顾、德尔菲专家函询、预调查形成量表初稿.采用便利抽样法,选取2022年5-8月在江苏省3所三级甲等综合医院消化科门诊就诊的200例IBD患者为研究对象进行问卷调查.采用临界比值法、相关分析法、内部一致性法、共同性与因素负荷量对量表进行项目分析;采用探索性因子分析、内容效度指数、内部一致性信度检验量表的信效度.结果 本研究共发放问卷200份,回收有效问卷181份,问卷有效回收率为90.50％(181/200).IBD患者菌群移植知信行量表包含认知、态度、行为3个维度,共21个条目.量表水平的内容效度指数为0.917,条目水平的内容效度指数为0.833～1.000.探索性因子分析提取出3个公因子,累积方差贡献率为74.197％.总量表的Cronbach's α系数为0.951,各维度的Cronbach's α系数为0.914～0.942;总量表的重测信度系数为0.918,各维度的重测信度系数为0.737～0.833.结论 IBD患者菌群移植知信行量表具有良好的信效度,可帮助医护人员评估患者对菌群移植的了解及接受程度,为医患共同决策的个性化沟通提供依据.
Abstract
Objective To develop the Fecal Microbiota Transplantation Knowledge,Attitude,and Practice Scale for Patients with Inflammatory Bowel Disease(IBD),and test its reliability and validity.Methods Guided by the theory of knowledge,attitude,and practice,a preliminary draft of the scale was formed through literature review,Delphi expert consultation,and pre-survey.From May to August 2022,convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three Class Ⅲ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey.The critical ratio method,correlation analysis method,internal consistency method,commonality and factor loadings were used for item analysis of the scale.Exploratory factor analysis,content validity index,and internal consistency reliability were applied to test the reliability and validity of the scale.Results A total of 200 questionnaires were distributed,and 181 valid questionnaires were collected,with an effective response rate of 90.50％(181/200).The Fecal Microbiota Transplantation Knowledge,Attitude,and Practice Scale for Patients with IBD included three dimensions of knowledge,attitude and practice,with a total of 21 items.The content validity index at the scale level was 0.917,and the content validity index at the item level ranged from 0.833 to 1.000.Exploratory factor analysis extracted three common factors,with a cumulative variance contribution rate of 74.197％.The Cronbach's α coefficient of the total scale was 0.951,and the coefficients of each dimension were 0.914 to 0.942.The test-retest reliability coefficient of the total scale was 0.918,and the test-retest reliability coeficients of each dimension ranged from 0.737 to 0.833.Conclusions The Fecal Microbiota Transplantation Knowledge,Attitude,and Practice Scale for Patients with IBD has good reliability and validity,which can help medical and nursing staff evaluate patients'understanding and acceptance of microbial transplantation,so as to provide a basis for personalized communication in shared decision making between doctors and patients.
