Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Compassion-focused therapy (CFT) seeks to lower shame and help people develop compassion for personal distress and shortcomings. There is increasing evidence to support the benefits of incorporating CFT-based interventions into the treatment of eating disorders (EDs). Building on the investigators' prior research, this study will examine the effects of a two-week CFT-based self-compassion letter-writing intervention on patients with eating disorders. Participants will be recruited from the wait-list of patients scheduled to begin treatment at the outpatient St. Joseph's Healthcare Hamilton Eating Disorders Program, and will be randomly assigned to the two-week letter-writing intervention or to a control group. Results will inform the integration of new empirically-derived interventions into ED treatments to improve the currently dismal rates of ED recovery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study consists of two phases. In phase one, participants will be randomly assigned to a two-week daily letter-writing intervention condition or a two-week control condition; phase one will occur two to four weeks prior to the start date of group ED treatment. Participants will complete a brief set of online questionnaires pre-, mid-, and post- two-week condition (i.e. baseline, after one week, and after two weeks).

Following these two weeks of intervention/control condition, all participants will complete a 25-week group treatment program as scheduled by the Eating Disorders Program. For phase two of the study, participants will be asked to complete questionnaires after 5 weeks, after 11 weeks, and post-group treatment. Data that is routinely collected as part of patients' clinical care pre- and post-treatment (i.e. on the first day and last week of group treatment) will also be collected.
