Abstract

Comparing self-assessed indicators of subjective outcomes (such as health, or job satisfaction) across countries or socio-economic groups is often hampered by the fact that different groups use different response scales. Anchoring vignettes are used as a tool to identify and correct for such differences. The paper develops a model in which objective measurements are used to validate such vignette-based corrections. The model is illustrated with an application to objective and subjective self-assessments of drinking behaviour by students in the Republic of Ireland. Model comparisons using the Akaike information criterion favour a specification with response consistency and vignette-corrected response scales. Put differently, vignette-based corrections appear quite effective in bringing objective and subjective measures closer together.
