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.

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.
Behavioral: Integrative Response Therapy
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.
Behavioral: Cognitive Behavioral Therapy
A 10 session manualized version of CBT-GSH is employed . Each of the 10 group therapy sessions will be 60 minutes in length. Non-specialty trained Masters-level therapists will lead CBT-GSH after undergoing CBT-GSH training with the PI.
