In Pursuit of Anchoring Vignettes That Work: Evaluating Generality Versus Specificity in Vignette Texts.

ABSTRACT:

Objective

Anchoring vignettes appear with growing frequency in surveys of health and aging, but little research investigates how to optimize their wording. This study experimentally tests whether mentioning specific health conditions and/or medical procedures enhances or undermines vignette validity.

Methods

Three series of general health anchoring vignettes were fielded to 2,550 respondents in the Wisconsin Longitudinal Study: one mentioning no specific health conditions or procedures, one mentioning heart disease-related ones, and one mentioning diabetes-related ones. Variations on hierarchical ordered probit models were used to test whether vignette wording affected adherence to the key measurement assumptions of vignette equivalence (VE) and response consistency (RC).
