Teenthrive 2: Treatments for Improving Mood in Teens

In this study, we will conduct a pilot RCT of a yoga-based intervention (YBI) vs. group cognitive-behavioral therapy (gCBT) at two sites. We will recruit 48 adolescent participants each in Columbus, OH and Boston, MA (96 total). We have a priori targets for indices of feasibility and acceptability, including recruitment rate, retention for assessments, class attendance, interventionist fidelity to manuals, and participant satisfaction. We hypothesize that we will meet these metrics at both sites.
