A number of factual and attitudinal questions asked in the 1973 Taiwan KAP-4 survey were repeated in a postenumeration survey one month later in order to assess the reliability of responses of the 286 women reinterviewed. The level of reliability is found to vary depending on the measures used and on whether the focus is aggregate data or individual responses. Analysis of consistency of responses shows that while overall reliability at both aggregate and individual levels is reasonably good, there is greater reliability for factual than for attitudinal data. Nevertheless, consistency of responses on factual questions varies considerably depending on the salience of the topic to the respondent. Estimates of reliability are shown to depend on the measure used and on the skewness of the distributions of the responses.
1973年台湾知识、态度与实践-4调查中提出的一些事实性和态度性问题，在一个月后的事后调查中再次被问及，以便评估再次接受访谈的286名女性回答的可靠性。结果发现，可靠性水平因所采用的测量方法以及关注的是汇总数据还是个体回答而有所不同。对回答一致性的分析表明，虽然汇总层面和个体层面的总体可靠性都相当不错，但事实性数据的可靠性高于态度性数据。然而，关于事实性问题的回答一致性会因主题对受访者的显著程度而有很大差异。结果表明，可靠性估计取决于所使用的测量方法以及回答分布的偏度。
