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.
方法利用一次性調(diào)查資料，建立問卷的理論模型并采用驗證性因子進行驗證；采用隨機單面交叉設計的一元概化模型和多元概化模型分析問卷的信度；采用Cronbachα信度系數(shù)估計問卷的內(nèi)部一致性信度。
