Online Cognitive Behavioural Therapy for Substance Use Disorder: The Impact of Peer Support

March 26, 2026 updated by: Lena Quilty, Centre for Addiction and Mental Health
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.

Study Overview

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Online Cogntivie Behavioural Therapy

Breaking Free Online (BFO) is an online intervention, supporting adults struggling with substance use. It provides psychoeducation and skills building exercises in CBT and compatible approaches. The intervention strategies contained within BFO are provided via a six-domain biopsychosocial model used in CBT. Each domain of the model corresponds to a module in the BFO program which contains psychoeducation and an 'action' strategy to facilitate behaviour change. Data captured at the baseline assessment is used by the program to provide feedback to the individual on their levels of functioning across the six domains. The program then guides the user to concentrate on intervention strategies for domains with the greatest level of impairment.

All groups will receive 'clinical monitoring,' including biweekly study assessments during the acute treatment period and monthly assessments during the six month follow-up period.

Interactive program utilizing cognitive behavioural therapy principles that guides users through its components and provides feedback, which facilitates behavior change (i.e., reduction in alcohol or substance use).
Other Names:
  • Breaking Free Online (BFO)
Experimental: Online Cognitive Behavioural Therapy Plus Individual Peer Support

BFO delivered with peer support will comprise BFO with at least weekly contact with a peer with lived experience. Peer support workers will receive training on how to facilitate participant engagement with and progress through the BFO program, as well as a weekly session plan. As part of this training, peer support workers will be given their own access code to use BFO and be encouraged to use the program. Session One constitutes an initial orienting to the program. Subsequent sessions review each information and action strategy in the BFO program, with a series of prompts to guide peer support of this content.

All groups will receive 'clinical monitoring,' including biweekly study assessments during the acute treatment period and monthly assessments during the six month follow-up period.

Other Names:
  • Breaking Free Online (BFO)
Weekly meetings with a trained peer support worker who guides participants through the BFO platform, reviews the platform's content with them, and supports them in the creation of an action strategy based on the platform's suggestions.
Other Names:
  • BFO Peer Support
Active Comparator: Group Peer Support

The control condition will consist of group peer support facilitated by trained peers and offered through the Community Addictions Peer Support Association (CAPSA). The group meets weekly and will offer participants a space to share their experiences and receive support.

All groups will receive 'clinical monitoring,' including biweekly study assessments during the acute treatment period and monthly assessments during the six month follow-up period.

Meetings with a group of peers led by a trained peer support worker/volunteer which will offer the participants an opportunity to discuss their experiences in a supportive and open environment.

Time Frame
Qualitative Interview
Time Frame: 10 months
This interview will follow established principles of qualitative research and include questions specifically designed for this study. This interview will have a two-pronged focus including (1) barriers and facilitators to the implementation of online CBT and (2) a complementary ethnographic focus on "health work" patients engage in to understand the impact of online CBT and explore ways to optimally deliver support during the care journey. Thematic analysis of interview data will be undertaken to offer a summative description of how patients give meaning to their experience.
