The investigators will enroll 200 justice-involved youth on probation 13-18 years old of all genders who report regular access to an Apple or Android smartphone. Following completion of a baseline questionnaire, participants will be individually randomized at a 1:1 ratio to 1 of 2 smartphone app conditions: (1) Bodhi AIM (Action In Mindfulness), a 30-day mindfulness-based intervention, or (2) HIB (Health In Balance), a health promotion control app matched to Bodhi AIM for time and structure. Follow-up assessments will occur at 1 and 6 months.
This study is a randomized controlled trial (RCT) testing the effects of a mindfulness-based intervention delivered to justice-involved youth on probation via smartphone app on youths' emotion regulation and HIV/sexually transmitted infection (STI) risk-taking behaviors (i.e., alcohol use, cannabis use, sexual behaviors, and aggressive behaviors).
