Immediate Treatment

EXPERIMENTAL

Pocket Skills is a dialectical behavior therapy skills training (DBT-ST) webapp that includes video lessons, an interactive chatbot AI coach, and in-app exercises to practice DBT skills. The delivery of the app intervention will be primarily monitored for one month, but followed for up to 3 months, and will be supplemented with a walk through manual and links to DBT worksheets. The intervention will be delivered in conjunction with treatment as usual which includes standard psychosocial care (e.g., assessments, group, and individual programming) as part of the Addictions Program or greater community.

Behavioral: Dialectical behavioral therapy skills training (DBT-ST)

Waitlist and Delayed Treatment

ACTIVE COMPARATOR

Waitlist control whereby outpatients or members of the community will wait 1 month (4 weeks) to receive the intervention and then receive the Pocket Skills webapp for the subsequent 2 months (8 weeks). The waitlist period and subsequent intervention will be delivered in conjunction with treatment as usual which includes standard psychosocial care (e.g., assessments, group, and individual programming) as part of the Addictions Program.
