Arm Description
16 weeks of Group Psychodynamic Interpersonal Psychotherapy for patients with Binge Eating Disorder, matching them by attachment anxiety dimensions in order to enhance the impact of the therapy. It is hypothesized that by optimally matching patients to groups, they will have better clinical and health outcomes.

Outcomes
Primary Outcome Measures
Frequency of Binge Eating in the Past 28 Days
Secondary Outcome Measures
Depression Symptoms
Early response to treatment is indicated by a reduction in depression symptoms measured by The Beck Depression Inventory II (BDI-II; Beck, Steer, & Brown, 1996). The BDI-II is scored by summing the ratings for the 21 items. Each item is rated on a 4-point scale ranging from 0 to 3. The range for this scale is 0-63. Higher scores represent more depressive symptoms. We included cases that were missing up to 8 missing items and calculated scores for participants with missing items by taking the weighted mean and multiplying by 21.

5. Study Description
Brief Summary
The main objective of the proposed study is to determine whether the effectiveness of a group therapy treatment for Binge Eating Disorder (BED) is improved and attrition reduced by optimally matching women with BED who have high attachment anxiety to Group Psychodynamic Interpersonal Psychotherapy (GPIP). This study represents the next phase in a program of research stemming from a previously conducted randomized controlled trial (RCT).

Group Psychodynamic Interpersonal Psychotherapy
Intervention Description
This intervention will consist of 16 weekly 90 minute sessions of Group Psychodynamic Interpersonal Psychotherapy (GPIP). GPIP was developed and empirically tested in a randomized controlled trial (RCT) at our Centre.
