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.
我们针对锚定 vignettes 识别分类评估报告中的异质性所依据的两个假设提出了检验方法。任意两个 vignette 状态之间感知差异的系统变化足以拒绝 vignette 等价性。响应一致性——即受访者使用相同的响应量表来评估 vignette 和其自身——在有足够全面的独立识别响应量表的客观指标时是可检验的。在一组年长的英国个体样本中,对于认知和身体功能的报告,这两个假设均被拒绝,不过基于较宽松假设的较弱检验并未拒绝认知方面的响应一致性。
