Overview

The goal of this clinical trial (CT) is to learn more about emerging adults' and their peers. Here, we will see how co-participating with a peer in health program might impact brain and behavior change over time.

Eligible youth will be invited to come in for a "Participation Day," during which they and a peer will independently complete questionnaires. With a peer, they will then complete a short health program, and undergo a brain scan (fMRI) while completing activities. Our study team will reach out to each participant individually again 3, 6, and 12 months later to learn about health behaviors over time.
