NCT06857903

Brief Summary

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.
