方差成分模型在职业紧张研究个体效度评价中的应用

Applying Variance Component Model to Evaluate the Individual Validity in Occupational Stress Research

目的探讨如何用方差成分模型评价职业紧张研究的个体效度,即量表是否反映了个体特征,以及个体是否如实完成了问卷的效度评价方法。方法通过方差成分模型获得单位内相关系数对个体效度进行评价。结果分析结果提示对一些填表随意性大,非临床一线科室及组织不力的科室个体效度偏低。结论方差成分模型可用于评价个体完成问卷的情况,对个体效度偏低的数据可以合理地剔除。
