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.
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).
