目的:考核骨质疏松症危险因素和中医证候调查问卷的信度,以完善调查问卷的条目。方法:采用横断面调查的方法,在上海市徐汇区和北京市东城区社区40-65岁妇女开展问卷调查,建立数据库并以获得的1 740例调查数据为基础,通过分析信度指标(概化系数Eρ2)和可靠性指数(φ),评价调查问卷的信度。结果:被调查者与条目的交互效应变异分量的估计值为0.8350,占总变异70.31%,是变异的主要来源。决策研究中相对误差变异σ2(δ)为0.0226,概化系数Eρ2为0.9121。结论:调查问卷的整体信度高,质量较好,但在条目数量上尚需精简。
Objective: To assess a osteoporosis questionnaire's reliability on risk factors and traditional Chinese medicine(TCM) syndromes,and to improve the questionnaire.Methods: Through a cross-sectional survey,we conducted an questionnaire survey on osteoporosis risk factors and TCM syndromes among women aged 40-65 in Xuhui District(Shanghai) and Dongcheng District(Beijing) communities,and established a database and obtained 1 740 cases of survey data.The reliability was assessed through analyzing the reliability index(generalized coefficient Eρ2) and index of dependability(Φ).Results: The estimated value of interaction effects variance component was 0.8350,70.31% of the total variance,and was the main source of variance.On decision study,the relative error variance was 0.0226,and generalized coefficient Eρ2 was 0.9121.Conclusion: The questionnaire has good reliability,but the number of items needs to be reduced.
