Using Nudges to Recruit for Health-Related Research

August 31, 2025 updated by: Kimberly Kaphingst, University of Utah

Using Nudges to Recruit Human Subjects in Clinical & Translational Research

The goal of this clinical trial is to examine the effect of using behavioral nudges in recruitment into a minimal risk interview study among healthy adult volunteers.

Individuals will be randomized to receive recruitment materials that do or do not contain a set of behavioral nudges. Researchers will compare the effect on participation in an interview study (primary outcome) between these conditions.
