Brief Summary:
The "Brain Over Binge Recovery Guide" (Hansen, 2016), is a self-help approach that incorporates fundamental aspects of Acceptance and Commitment Therapy, Dialectical Behavioural Therapy, Motivational Enhancement Therapy and addictions treatment. This approach has been streamlined into a guided self-help protocol (Binge Focused Therapy, or BFT) that can be delivered by undergraduate students with minimal mental health experience in 3 group sessions spread over 8 weeks (i.e., Week 1, Week 2, Week 8). The aim of this proof-of-concept study is to provide preliminary data to examine whether this approach is feasible and has clinical potential for patients with binge eating disorder.

Binge Focused Therapy (BFT) Intervention
Behavioral: Binge Focused Therapy (BFT) Intervention
The intervention, Binge Focused Therapy, is a 3-session, 8-week, non-expert guided self-help program. Participants will attend sessions at Week 1, Week 2, and Week 8 at the Nova Scotia Health Authority Eating Disorder Clinic. Each session will be approximately 2 hours in length.

Primary Outcome Measures :
  1. Change in Binge Eating Frequency [ Time Frame: Baseline, Week 8, 1-year follow-up ]
    Self-reported binge eating frequency will be assessed with the Eating Disorder Examination Questionnaire 6.0 (EDE-Q). Binge eating frequency is measured on item 15 of the EDE-Q.

Secondary Outcome Measures :
  1. Change in Binge Eating Severity [ Time Frame: Baseline, Week 2, Week 8, 1-year follow-up ]
    Self-reported binge eating severity will be assessed with the Binge Eating Scale (BES). The BES is a 16-item measure, each item has 3-4 coded responses. The total score ranges from 0-46, where a higher score indicates greater binge eating severity.

  2. Remission Rate [ Time Frame: Week 8, 1-year follow up ]
    Remission defined as 100% reduction in binge episodes in the last 28 days of treatment phase preceding week 8, or in the last 28-days of follow-up phase.

  3. Response Rate [ Time Frame: Week 8, 1-year follow up ]
    Responders defined as ≥ 50% reduction in the number of binge episodes from baseline to either of the last two preceding weeks of treatment or follow-up.

  4. Change in General Eating Disorder Symptomatology [ Time Frame: Baseline, Week 8, 1-year follow-up ]
    Self-reported general eating disorder symptomatology will be assessed using the global score generated from the EDE-Q. The EDE-Q is a 28-item measure that assesses four areas of eating disorder psychopathology (eating concern, shape concern, weight concern, dietary restraint). Each item uses a Likert scale ranging from 0 (lowest frequency/severity) to 6 (highest frequency/severity). The global score ranges from 0-6 where higher scores indicate greater impairment. The global score is obtained using the mean of the four subscales.

  5. Change in Locus of Control of Behaviour [ Time Frame: Baseline, Week 2, Week 8, 1-year follow-up ]
    Self-reported locus of control of behaviour will be assessed using the Locus of Control of Behaviour scale (LCB). The LCB scale is a 17-item measure. Participants respond to each item using a Likert scale ranging from 0 (strongly disagree) to 5 (strongly agree). Total scores range from 0-85, with higher scores indicating a greater degree of externality.

  6. Change in Coping Self-Efficacy [ Time Frame: Baseline, Week 2, Week 8, 1-year follow-up ]
    Self-reported coping self-efficacy will be assessed using the Coping Self-Efficacy Scale (CSES). The CSES is a 26-item measure. Each item with be rated using a Likert scale from 1 (cannot do at all) to 10 (certain can do). An average score will be obtained. Higher scores indicate greater coping self-efficacy.

  7. Motivation/Confidence/Readiness for Behaviour Change [ Time Frame: Baseline and Week 2 ]
    This will be measured using responses to three Likert-style questions that assess the perceived value of changing binge eating, confidence in ability to change binge eating, and readiness to change binge eating. Each item will be scored on a scale of 1 (not at all important/confident/ready) to 10 (extremely important/confident/ready). Each item will be assessed independently. Higher scores indicate greater motivation, confidence, and readiness.

  8. Depression, Anxiety and Tension/Stress [ Time Frame: Baseline ]
    Self-reported depression, anxiety, and tension/stress will be assessed using the Depression Anxiety Stress Scale (DASS). Participants will respond to 21-items each scored on a Likert scale from 0 (did not apply) to 3 (applied very much or most of the time). A total score ranges from 0-126 with a higher score indicating greater impairment.

  9. Participant Satisfaction with Intervention [ Time Frame: Week 8 ]
    Participants will respond to 3 Likert-style questions on a scale of 1 (very poor) to 6 (excellent) and several open-ended questions asking about their perceptions of the program. Higher scores indicate greater satisfaction.

  10. Week 3 - 7 Adherence [ Time Frame: Week 8 ]
    Participants' adherence to tracking binge frequency and use of defusion skills (i.e., Homework) between Sessions 2 and 3.
