univariate generalizability model

MethodsBased on once-administrated investigation data, the questionnaire's theoretical model was established and validated by Confirmatory Factor Analysis. Random one-facet crossed design Univariate Generalizability Model and Multivariate Generalizability Model were used to estimate the reliability of the administrated questionnaire.
方法利用一次性调查资料，建立问卷的理论模型并采用验证性因子进行验证；采用随机单面交叉设计的一元概化模型和多元概化模型分析问卷的信度；采用Cronbachα信度系数估计问卷的内部一致性信度。
