Arm && Interventions

Group	Intervention	Description
High attachment anxiety condition	Group Psychodynamic Interpersonal Psychotherapy	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.
Low attachment anxiety condition	Group Psychodynamic Interpersonal Psychotherapy	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.

Primary Outcome Measures

Name	Time	Method
Frequency of Binge Eating in the Past 28 Days	Pre and Post treatment, 6 months and 1 year

Secondary Outcome Measures

Name	Time	Method
Depression Symptoms	Pre and Post treatment, 6 months and 1 year	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.
