摘要: 目的·编制社区医护人员骨质疏松症防控行为量表,并对量表的效度和信度进行评价。方法·在上海20家骨质疏松症规范化诊疗试点社区卫生服务中心,采用方便抽样的方式抽取400名医护人员进行调查,并在初次调查后的2周再从中随机抽取20名医护人员进行量表测定。采用内容效度、结构效度检测量表的效度。采用内部一致性克隆巴赫系数(Cronbachs α)、重测信度及分半信度3个指标检测量表的信度。结果·通过项目分析筛选,保留19条条目。在删除1条内容效度指数(item-level content validityindex,I-CVI)低于0.78的条目后,量表的全体一致量表内容效度指数(scale-level CVI/universal agreement,S-CVI/UA)和平均量表内容效度指数(scale-level CVI/average,S-CVI/Ave)分别为0.944和0.992。经探索性因子分析法提取了4个公因子,累积方差贡献率为85.94%;验证性因子分析结果与原假设一致,χ2/df3.323,CFI=0.971,GFI0.902,RMSEA0.076。该量表的总Cronbachs α系数为0.978,各维度的Cronbachs α系数也均大于0.9。各条目的重测信度大于0.7,总量表的重测信度为0.654;分半信度为0.932。结论·社区医护人员骨质疏松防控行为量表具有良好的信度和效度,可用于社区医护人员骨质疏松防控行为实施情况的测量。

Abstract:

Objective · To compile the osteoporosis prevention and control behavior scale for health care workers in community and evaluate its validity and reliability. Methods · In 20 standardized diagnosis and treatment pilot community health service centers for osteoporosis in Shanghai,400 healthcare workers were conveniently sampled to conduct the survey and 20 of them who were randomly sampled underwent retest 2 weeks later. The validity of the scale was evaluatedcontent validity and structural validity. The reliability of the scale was testedCronbachs α coefficient, retest reliability and split-half reliability. Results · A total of 19 items were retained after project analysis. Scale-level content validity index/universal agreement (S-CVI/UA) and scale-level CVI/average (S-CVI/Ave) were 0.944 and 0.992, respectively, after an entry with item-level CVI (I-CVI) less than 0.78 was deleted. Four common factors were extractedexploratory factor analysis, and the cumulative variance contribution rate was 85.94%. Results of confirmatory factor analysis indicated that the model was consistent with the theoretical assumption, and the fitness indexes χ2/df, CFI, GFI, and RMSEA were 3.323, 0.971,0.902, and 0.076, respectively. The overall Cronbachs α coefficient of this scale was 0.978 and the Cronbachs α coefficients of the four dimensions were all over 0.9. The intraclass correlation coefficient (ICC) of each item was greater than 0.7, and the ICC of the total scale was 0.654. The split-half reliability coefficient was 0.932. Conclusion · The osteoporosis prevention and control behavior scale has good reliability and validity and can be used to evaluate the implementation of osteoporosis prevention and control behavior of health care workers in community.
