Binge Eating Disorder Treatment Study

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).

Treatment and study plan

Group Psychodynamic Interpersonal Psychotherapy

Behavioral

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. GPIP will be preceded by an individual pre-group preparation session conducted by a psychologist trained in GPIP to orient the patient to the therapy. Patients are given a rationale for the treatment.

Primary outcomes

  1. Frequency of Binge Eating in the Past 28 Days

    Time frame: Pre and Post treatment, 6 months and 1 year

Secondary outcomes

  1. Depression Symptoms

    Time frame: 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.
