The importance of development standards for anchoring vignettes: an illustrative example from pediatric localized scleroderma quality of life.

ABSTRACT:

Purpose

Anchoring vignettes (AVs) are a promising measurement technique to reduce bias in patient-reported outcome (PRO) measures by helping researchers understand differences in how individuals and groups interpret response options. However, little attention has been paid to ensure quality development of AVs, and their performance has not been well assessed in pediatric populations. In this study, we explore the application of a rigorous development process for AVs based upon current standards for PROs, as well as feasibility of AVs when administered to children and adolescents.

Methods

We developed AVs using a rigorous, patient-centered mixed methods process including three phases: (1) development, (2) a pilot study, and (3) a field test. Our proposed process included the
