Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Treatment: Other
Comparator / control treatment
Use of a similar existing feedback tool that focuses on general process-based outcomes as opposed to specific eating disorder symptoms.

The Outcome Rating Scale (ORS; Miller et al., 2003) is a self-report, brief visual analogue measure, providing a measure of general patient progress in relation to overall wellbeing, and individual, interpersonal, and social wellbeing.

In the control group this questionnaire will be administered weekly over the course of treatment, (duration 20-40 weeks), and takes no more than 2-3 minutes to complete.
