Guided Self-Help for Binge Eating Disorder
Comparison of Integrative Response Therapy and Cognitive Behavioral Therapy Guided Self-Help for Binge Eating Disorder

Intervention / Treatment
Detailed Description
The focus of this proposal is on BED among an adult population. Guided self-help treatments (GSH) for BED appear promising and may be more readily disseminated than efficacious specialty treatments such as Cognitive Behavioral Therapy (CBT) and Interpersonal Psychotherapy (IPT) given the latter's administration costs and time requirements. The proposed study uses a new group-based, guided self-help BED treatment called Integrative Response Therapy (IRT). IRT is primarily based upon the affect regulation theory of binge eating (e.g., binge eating is an attempt to alter distressing emotional states), while adding cognitive restructuring techniques. IRT teaches effective ways to cope with aversive emotions and reframe faulty cognitions while reducing vulnerabilities that are likely to lead to problematic emotional responding & cognitions such as physical needs (e.g., hunger, sleep deprivation), interpersonal conflict, and, when possible, unpleasant external events. IRT's primary goal is to significantly decrease episodes of binge eating and associated eating disorder pathology.
CBT-GSH is a frequently used manual-based form of GSH that has demonstrated efficacy. CBT, based on the restraint model, intervenes via behavioral techniques to replace restrained eating with more regular eating patterns and cognitive techniques to restructure an individual's problematic thoughts that over-evaluate shape and weight. Research literature indicates that CBT-GSH is a viable self-help BED treatment that appears to be superior to wait-list control conditions, equivalent to IPT, a specialty treatment, and superior to Behavioral Weight Loss treatment at 2-year follow-up. There are then, a number of reasons for further research on GSH in general and CBT-gsh specifically.
The proposed study will lay the groundwork for identifying which GSH treatment should be investigated in a subsequent, larger trial that would evaluate a clinically relevant algorithm for the treatment of BED.

Genders Eligible for Study
Description
Inclusion Criteria:
- Meet DSM-IV research criteria for Binge Eating Disorder (although frequency criteria will be lessened to that proposed in DSM-V;1 time per week for 3 months).
- Be male or female between 18 and 75 years.
- Be available and committed to attend full treatment and follow-up
- Adequate transportation to the clinic.
- Be literate in English (this is required for inclusion because sessions will be conducted in English and written and visual materials are in English).
- Have a Primary Health Care Provider.
Exclusion Criteria:
- Current psychosis or severe depression with suicidal risk; a severity that would likely require additional psychotherapeutic or psychopharmacologic treatment or interfere with participation in this group therapy or with day to day functioning. Depressive disorders not meeting the intensity factor of the exclusion criteria may be entered to the study.
- Current Anorexia or Bulimia Nervosa or purging behaviors over the past six months.
- Current drug and/or alcohol abuse/dependence.
- Current medication primarily indicated for its effect on appetite or weight, unless the participant is willing to withdraw from such medications under supervision of their primary care physician.
- Current chemotherapy.
- Current participation in psychotherapy, unless the participant is willing to discontinue treatment.
- Psychotropic medication use, including antidepressants, are acceptable if doses were stable for at least 1 month prior to assessment.
- Pregnant or plans to become pregnant within the next 12 months.
- BMI greater than 45.
- Planning to have Bariatric surgery within the next 12 months.
- No transportation

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Integrative Response Therapy
IRT is based on affect regulation theories of binge eating and adds emphasis on cognitive restructuring techniques.
IRT is a 10 session, group-based, guided-self-help treatment that works to decrease binge eating by primarily enhancing emotion coping skills, in addition to transforming faulty interpretations and reducing vulnerabilities (e.g., interpersonal events) that risk overwhelming emotion and problematic cognitions.
|
A 10 session manualized version of IRT is employed .
Each of the 10 group therapy sessions will be 60 minutes in length.
Non-specialty trained Masters-level therapists will lead IRT after undergoing IRT training with the PI.
|
Active Comparator: Cognitive Behavioral Therapy
Cognitive Behavioral Therapy guided self-help (CBT-GSH), based on the restraint model of binge eating, has been adapted from individual format to a 10 session, group-based therapy for the purpose of this study.
The book 'Overcoming Binge Eating' is employed in the present study and consists of Part 1, an educational background on BED, and Part 2, a 6 step treatment program to overcome binge eating.
