The correspondence between survey responses to a number of factual questions and information from independent verification sources (i.e., concurrent validity) was examined by age of respondents. The relevant data were drawn from four different surveys that included questions referring to issues of physical health, voting behavior, transportation, charitable contributions, library patronage, and age. Generally, there was little evidence that older respondents report factual information less validly than younger respondents; only chronological age was reported somewhat less validly by older respondents.
根据受访者年龄，对一些事实性问题的调查回复与来自独立核实来源的信息之间的对应关系（即同时效度）进行了检验。相关数据取自四项不同的调查，这些调查包含了涉及身体健康、投票行为、交通、慈善捐款、图书馆借阅以及年龄等问题。总体而言，几乎没有证据表明年长受访者报告事实信息的效度低于年轻受访者；只有实际年龄在年长受访者中报告的效度略低。
