Is the Anchoring Vignette Method Sensitive to the Domain and Choice of the Vignette?
研究了锚定情景法在不同健康领域（认知、呼吸、行动能力）中是否因情景选择不同而结果不同，发现认知和呼吸领域的结果对情景选择敏感，行动能力领域则更稳健。
Summary Analysis of self-assessments may yield biased results when respondents use the response categories of survey questions in different ways. An anchoring vignette is a short description of relevant aspects of a hypothetical person’s life and can be used to correct self-assessments for heterogeneity in reporting behaviour. The paper studies the validity of the parametric model for the anchoring vignette method. Rather than testing separately the assumptions of this model, we take the following two approaches. First, we study whether different vignettes within a certain domain lead to similar adjusted self-assessments. Second, we study whether different adjusted self-assessments, each adjusted by using a single vignette, are closer to a measure of the actual situation than the unadjusted self-assessments. We use data from the 2004 and 2007 waves of the Survey of Health, Ageing and Retirement in Europe for three domains of health: cognition, breathing and mobility. Our results indicate that the anchoring vignette method is sensitive to the choice of the vignette for cognition and breathing, whereas the results for mobility are more encouraging.
