摘要
为评价问卷的信度，探讨组内相关系数的简单算法及其假设检验，作者用一实例说明怎样通过方差分析表较为简便地计算和检验组内相关系数。结果表明：实例中问卷的复测信度较高。通过方差分析表可方便地计算并检验组内相关系数，该方法既可用于定量资料。
To evaluate the reliability of questionnaire and expound the simple
method of calculating and testing the intraclass correlation coefficient (ICC), the authors gave an
example of how to simply calculate and conduct the hypothesis testing of ICC by using the
analysis table of variance. The results demonstrated a high test retest reliability of the
illustrative questionnaire. By using ANOVA table, the calculation and hypothesis testing of the
ICC is easy to do. The method can be used in the analysis of quantitative data, and categorical
data as well.
