The purpose of this study is to compare the feasibility, acceptability, and efficacy of a dialectical behavior therapy skills training webapp known as "Pocket Skills" in outpatients and community members seeking treatment for substance use, across those who receive immediate versus delayed access to the intervention (e.g., a waitlist control condition).
Seventy adult outpatients and community members seeking treatment for substance use from the Centre for Addiction and Mental Health Addictions Program will be randomized to receive immediate or delayed (1 month) access to a web-based DBT skills training intervention called Pocket Skills in addition to standard care. Participants will complete interviews and questionnaires at baseline. Following baseline, participants complete questionnaires at months 1, 2, and 3 months. Measures will assess alcohol and drug consumption, substance use disorder symptoms, and other clinical features.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| 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. |
