Testing a Digital Intervention for Adolescents

Study Overview
=================
Brief Summary
-----------------
Teen participants (ages 13-17) will be randomly assigned to either an experimental (the Happify Teens digital platform), or a waitlist control group. The study includes an 8-week intervention period and a 1-month follow up period.

Detailed Description
-----------------
Teen participants (ages 13-17) will be randomly assigned to either the experimental group in which participants receive access to Happify Teens, a digital platform rooted in several therapeutic traditions that aims to improve wellbeing, or a waitlist control group. Both group conditions last 8 weeks. Participants assigned to the Happify Teens platform will have full access to the intervention, with featured tracks that focus on dealing with stress, worries and building skills for greater happiness. Participants assigned to the waitlist (control) condition will not have access to the Happify Teens platform for the full study period (12 weeks total). Participants in the waitlist control will receive access to Happify Teens after the full study period is complete (12 weeks). Perceived stress, rumination, and optimism will be assessed via self-report at baseline, end of the 8-week intervention, and at 1 month post intervention.
