Intervention(s)

A clinical feedback tool that provides a trajectory of eating disorder symptomatology for both "good" and "poor" outcomes over the course of therapy. It will be implemented into a regime of enhanced CBT for individuals with eating disorders.

A subset of Eating Disorder Examination- Questionnaire (EDE-Q; Fairburn & Beglin, 2008) items will be administered at pre-treatment and every subsequent week during treatment. (duration 20-40 weeks). This brief questionnaire will take approximately 2-3 minutes to complete. The scores will be utilised by the clinician between sessions to monitor the patient's progress. This will enable the clinician to to examine whether clients are making reliable change in their questionnaire scores (and thus eating disorder psychopathology), and to monitor when clients are approaching, or have reached, a score indicative of reaching the "healthy" range.. Patients' individual progress will be monitored weekly by the clinician.

Primary Outcome(s)

Change in eating disorder psychopathology over the course of treatment. To assess this, the EDE-Q global score will be used to assess change in eating disorder psychopathology over the course of treatment. [Pre and post-treatment, and at 5-session intervals over the course of treatment]

Secondary Outcome(s)

Treatment completion versus drop out[End of treatment (post-treatment, at 20 weeks for patients with a BMI > 18.5, post-treatment at 40 weeks for patients with a BMI < 18.5)]

Remission versus non-remission. Full Remission is defined as complete absence of eating disorder symptoms in the last 28 days, that is, 1) cessation of all key eating disorder behaviours, 2) BMI > or equal to 18.5, 3) not meeting the DSM criteria for an Eating Disorder Partial remission is defined as meeting all but 1 of the above criteria for full remission
[End of treatment (post-treatment, at 20 weeks for patients with a BMI > 18.5, post-treatment at 40 weeks for patients with a BMI < 18.5)]
