Binge Eating Disorder (BED) Clinical Trial
Official title:
Feedback Versus no Feedback to Improve Patient Outcome in Group Psychotherapy for Eating Disorders: A Randomised Clinical Trial
The current trial aims to investigate the impact of continuous feedback on dropout and outcome in group therapy. The hypothesis is that continuous feedback to patient and therapist on treatment progress and alliance will 1) increase adherence and 2) increase treatment outcome.
Background: In the psychotherapy of eating disorders, a dropout rate between 30% and 50% is
reported internationally. The fact that up to half of the patients drop out of treatment
calls for ways to improve it. Research shows that feedback to patient and therapist
increases outcome and reduces the number of dropouts; however there is only three published
works on the effect of feedback in eating disorders treatment. Therefore, the present trial,
at the eating disorders unit at Stolpegaard Psychotherapy Centre, Gentofte, Denmark, may
contribute to necessary improvements in the field.
Objective: The current trial, which will be conducted from August 2012 to August 2014, aims
to investigate the impact of continuous feedback on adherence and outcome in group
psychotherapy. The hypothesis is that continuous feedback to patient and therapist on
treatment progress and alliance will 1)increase adherence 2) increase treatment outcome.
Method: The trial is set up in a randomized design with 159 patients allocated to a)
treatment with feedback intervention or b) treatment as usual.
Participants: The participants are diagnosed with Bulimia Nervosa, Binge Eating Disorder or
Eating Disorder Not Otherwise Specified.
Interventions: In the experimental group, two sets of feedback measures are added to the
standard treatment: Outcome Rating Scale (ORS) and Group Session Rating Scale (GSRS). The
ORS assesses areas of life functioning known to change as a result of therapeutic
intervention. The GSRS assesses key dimensions of effective therapeutic relationships.
