Brief summary

Exposure and Response Prevention (ERP), delivered individually, is the gold-standard treatment for Obsessive-Compulsive Disorder (OCD). However, there are significant barriers to accessing this form of treatment such as a limited number of specialists skilled in the provision of the treatment and long wait-lists. As such,attention has been given to exploring alternative modes of delivery of ERP. These alternatives include provision of ERP via the Internet and provision of ERP in a group format. A recent meta-analysis (Schwartz et al., 2016) found that ERP provided in a group format has equivalent effect sizes to individually administered ERP. The 12 studies in the meta-analysis were controlled trials comparing group ERP to wait-list and to individual ERP. The results of this meta-analysis lend support for the provision of ERP in group formats in clinical practice. However, most studies to date have been conducted in highly controlled settings (e.g. university clinics) and so little is known about how effective group ERP is in typical clinical settings. The aim of this study is to evaluate the effectiveness of group ERP in a ‘real-world’ clinical setting.

Interventions

The intervention is exposure and response (ERP) therapy delivered in a group format. ERP is the gold-standard treatment for obsessive-compulsive disorder. Each session involves the review of homework exercises, provision of psych education regarding the maintenance of OCD, setting up hierarchies and exposure exercises. Group numbers will not exceed 10 per group. All sessions administered by two clinical psychologists trained in ERP. Adherence to the treatment occurs at the beginning of each sess

The intervention is exposure and response (ERP) therapy delivered in a group format. ERP is the gold-standard treatment for obsessive-compulsive disorder. Each session involves the review of homework exercises, provision of psych education regarding the maintenance of OCD, setting up hierarchies and exposure exercises. Group numbers will not exceed 10 per group. All sessions administered by two clinical psychologists trained in ERP. Adherence to the treatment occurs at the beginning of each session when homework tasks are reviewed. Homework exercises include planned exposure exercises, reading and monitoring mood and anxiety levels. The intervention will consist of 1 group session every week of 2 hours duration conducted over 10 consecutive weeks. A final follow-up session will be held one-month post-treatment
