我们提出的两个假设下，锚定小插曲识别异质性的分类评价报告的测试。任何两个晕影状态之间的感知差异的系统变化足以拒绝晕影等效性。回答的一致性-回答者使用相同的回答尺度来评价小插曲和她自己-是可以检验的，因为有足够全面的客观指标，可以独立地确定回答尺度。这两个假设都被拒绝报告的认知和身体功能在一个样本的老年人的英语个人，虽然一个较弱的测试不太严格的假设不拒绝响应一致性认知。
We propose tests of the two assumptions under which anchoring vignettes identify heterogeneity in reporting of categorical evaluations. Systematic variation in the perceived difference between any two vignette states is sufficient to reject vignette equivalence. Response consistency - the respondent uses the same response scale to evaluate the vignette and herself – is testable given sufficiently comprehensive objective indicators that independently identify response scales. Both assumptions are rejected for reporting of cognitive and physical functioning in a sample of older English individuals, although a weaker test resting on less stringent assumptions does not reject response consistency for cognition.
