【摘要】 目的 :探讨两水平方差成份模型在评价调查者间变异的应用价值。方法 :针对对问题的应答为连续性正态分布的数据 ,分别拟合了两水平方差成份模型进行对比分析。结果 :问卷中各个问题存在着一定的调查者间变异 ,但逐年改进。结论 :对于问卷项目的应答为连续性正态分布的数据 ,在拟合重复调查的情形下 ,可以采用两水平方差成份模型评价问卷项目应答的信度。更多还原

【Abstract】 Objectives:To explore the applicability of two level variance component model in research on variability between interviewers.Method:Based on the normally distributed data in response to the items of questionnaire the two level variance component models were employed separately in analysis for reliability of the three items in questionnaire.Results:Obtained the estimates of variability between interviewers of responding to the three items of questionnaire every years.Conclusion:In the condition of unrepeated measurement,the variability between interviewers can be estimated by fitting two level variance component model for normally distributed data.更多还原
