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(jìn)行驗證；采用隨機(jī)單面交叉設(shè)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。
