Teens Achieving Mastery over Stress (TEAMS) has been adapted for use with youth with I/DD. The intervention consists of virtual, manualized treatment groups for 10 weekly, 75-minute sessions plus 6 monthly, 60-minute sessions. Caregivers of participants will meet twice: weeks one and 16.

Teens Achieving Mastery over Stress (TEAMS) has been adapted for youth with I/DD. TEAMS Prevention is a 10-session group depression prevention program teaching teens how to deal with stress and negative moods, and ways to manage low mood based on cognitive behavioral therapy (CBT) principles and strategies. Efficacy has been demonstrated by several trials over time.

Competent Adulthood Transition with Cognitive-behavioral \& Interpersonal Training (CATCH-IT) has been adapted for youth with I/DD. CATCH-IT is an internet-based depression prevention program that targets decreasing modifiable risk factors while enhancing protective factors in at-risk adolescents, and that includes a parent program. It has been shown to be safe, feasible, and efficacious. All adolescents will receive 8 engagement texts during their participation in the study - at 1-week, 1-month, 6-weeks, and 2-, 3-, 5-, and 5.5-months - to encourage participation in the online modules.

The Strengthening Families caregiving curriculum is an evidence-based, self-directed, virtual skills training for caregivers. Information and instructions on accessing the Strengthening Families parenting skills training curriculum will be included on the virtual resource website https://strengtheningfamilieslessons.org/.

The BEST project will host a total of 10 virtual psycho-educational workshops per year (5 for participants and 5 for caregivers) for the duration of the intervention period of the study. Workshops will be delivered remotely via Zoom and facilitated by graduate students in health/behavioral health. Simultaneous language interpreter services will be provided. Principles of universal design in learning will be applied to the content and delivery of workshops. Workshops are an optional resource available to all participants and families in the intervention condition. Topics for the virtual discussion groups will be determined based on pilot data and input from participants and caregivers.
