NCT06831123

Brief Summary

This study involves a 3-arm randomized controlled trial designed to investigate the feasibility and acceptability of three preventive interventions designed to reduce risk for escalations in adolescent conduct problems. High school students identified to be at risk for conduct problems will be randomly assigned to one of three intervention options, including a mindfulness-based program, a mindfulness-based program augmented by a new mobile app, and a life skills program. Assessments related to intervention outcomes will be completed by adolescents, parents/guardians, and teachers at baseline, 2 weeks post-intervention, and at a 3-month follow-up.
