Development and validation of prescription drug risk, efficacy, and benefit perception measures in the context of direct-to-consumer prescription drug advertising.

ABSTRACT:

Purpose

Understanding patient perceptions of prescription drug risks and benefits is an important component of determining risk-benefit tradeoffs and helping patients make informed medication decisions. However, few validated measures exist for capturing such perceptions. The purpose of this study was to develop and validate measures of perception of prescription drug risk, efficacy, and benefit.

Methods

We conducted a mixed-methods study to develop and validate the measures, including three waves of quantitative testing (item nonresponse, criterion-related validity, and convergent validity). We conducted quantitative testing with a probability-based online consumer panel of U.S. adults (n = 7635), eliminating weaker items after each testing wave.
