Analysis on Reliability and Validity of TCM Syndrome Questionnaire of primary Osteoporosis

目的考核调查问卷的信度和效度,以完善原发性骨质疏松症中医证候调查问卷。方法通过分析克朗巴赫系数α、分半信度和表面效度、结构效度,评价调查问卷的信度和效度。结果各领域、方面以及问卷总体的克朗巴赫系数α在0.3654～0.8525之间,折半信度在0.5429～0.7465之间。因子分析共提取了12个初始特征值大于1的公因子,累计贡献率达到66.24%,因子分析结果反映了问卷设计时的几个重要方面。结论原发性骨质疏松症中医证候调查问卷具有一定的信度和效度,但尚需修改和完善。

Objective To evaluate reliability and validity to perfect the syndrome questionnaire of osteoporosis. Methods The reliability was evaluated with Cronbach alpha and Guttman Split-half, the construct and content validity of the questionnaire was evaluated with factor analysis. Results Thc Cronbach alpha is from 0.3654 to 0.8525. The Guttrnan Split-half is from 0.5429 to 0.7465. The factor analysis had extracted 12 common factors which initial eigenvalues bigger than one. Thc Cumulative Proportion is 66.24%. The factors cover all the main facets of the questionnaire.
