导尿管相关尿路感染预防知信行量表的编制及信效度检验

Validity and reliability of the knowledge-attitude-practice scale for prevention catheter associatedurinary tract infection measurement

目的编制导尿管相关尿路感染（CAUTI）预防知信行量表并对其进行信效度检验，为临床评估医护人员CAUTI预防的知识、态度、行为提供有效测评工具。 方法以知信行理论为框架、CAUTI预防指南为依据，采用文献回顾、Delphi专家函询、预调查法形成CAUTI预防知信行初始量表；选取青岛大学附属医院（三级甲等医院）300名医护人员进行调查，采用项目分析和探索性研究因子分析调查数据，进一步筛选条目；3周后重测，检测量表的信效度。 结果最终形成正式量表包括知识-留置尿管适应证、知识-CAUTI预防策略、态度、行为4个维度共45个条目，累计方差贡献率为63.21%；总量表Cronbach α系数为0.914，折半信度为0.812；总量表内容效度为0.895，各条目的内容效度为0.846~1.000；各维度与量表总分的相关系数为0.711~0.862，各维度之间的相关系数为0.425~0.564。 结论CAUTI预防知信行量表具有良好的信效度，可以用于评价医护人员CAUTI预防相关知识、态度、行为。

ObjectiveTo develop a scale of catheter-associated urinary tract infection （CAUTI） knowledge-attitude-practice （KAP） and to test its psychometric properties, and to provide effective assessment tools for clinical evaluation of knowledge, attitude and practice of CAUTI prevention. MethodsBased on KAP theory and CAUTI preventive current guideline, the scale was developed by using literature review, Delphi expert inquiry. A questionnaire survey was conducted among 300 medical workers in a third grade A hospital in Qingdao. Exploratory factor analysis and confirmatory factor analysis were both conducted to screen the items further. The psychometric properties of scale was tested. ResultsThe finalized scale included 4 subscales and 45 items, amount to 63.21% of the variance contribution rate. The total Cronbach＇s alpha was 0.914, and the split half reliability was 0.812. The content validity of the scale was 0.895, while it ranged from 0.846-1.000 for each subscale. The correlation of item-to total was 0.711-0.862, and the correlation coefficient of item-to-item ranged from 0.425-0.564. ConclusionsThe scale of CAUTI KAP has good reliability and validity. It can be used to evaluate CAUTI related knowledge, attitude and practice level of medical workers.
