A total of 225 outpatients receiving standard care for substance use disorder from the Centre for Addiction and Mental Health will be randomized to receive clinical monitoring (CM) with group peer support, Breaking Free Online only, or Breaking Free Online with individual peer support, in an eight-week trial with a six-month follow-up period. The primary outcome is substance use frequency; secondary outcomes include substance use problems, depression, anxiety, quality of life, treatment engagement, and cost-effectiveness.
The purpose of this study is to evaluate the efficacy and cost-effectiveness of Breaking Free Online, in a comparison of outpatients seeking treatment for substance use disorder who receive standard care with group peer support, versus with access to Breaking Free Online, versus with access to Breaking Free Online and individual peer support.
