Summary

Binge Eating Disorder (BED) affects as many as 3% of women and men in Ontario, 8% of obese individuals, and 30% to 50% of those participating in weight loss programs. BED, the most common eating disorder, is characterized by over-eating with loss of control (i.e., binge eating), but with no purging (e.g., vomiting).Our previous research indicates that the total health care costs for women with BED is 36% higher than the Canadian average for women of a similar age, and that health care costs significantly decreased following intensive treatment at our Centre. The main goal of our study is to inform the development of a stepped care approach to the treatment of BED. Stepped care involves providing easily accessible low intensity treatment first, and then providing more expensive intensive treatment second, if necessary. The second goal is to assess if a second more intensive step of treatment provides added value. Although stepped care for BED is suggested by a number of clinicians and researchers, no study adequately tests predictors of who might benefit from minimal treatment alone and who would require the more intensive second step. The results of this study will guide decision making regarding who benefits from stepped care, and will help to increase the accessibility, availability, and cost effectiveness of psychological treatments for BED.

Interventions

Type	Name	Description
BEHAVIORAL	Group Psychodynamic Interpersonal Psychotherapy	For those participants randomized to the USH + Group Psychodynamic Interpersonal Psychotherapy (GPIP) condition, this intervention will consist of 16 weekly 90 minute sessions of 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. Examples of the patient's cyclical relational patterns (CRPs) that may underlie their symptoms are discussed and the patient will be encouraged to work on these in the groups. Therapists will be given a written summary of each patient's CRP.
BEHAVIORAL	Unguided Self-Help	All participants will first receive 10 weeks of Unguided Self-help. The USH will be based on Dr. Christopher Fairburn's CBT-oriented and evidence based self-help treatment plan for binge eating explained in his book, Overcoming Binge Eating. The USH program follows six steps: (1) Getting Started: Self-monitoring, weekly weighing; (2) Regular Eating: Establishing a pattern of regular eating; (3) Alternatives to Binge Eating: Substituting alternative activities; (4) Problem Solving and Taking Stock: Practicing problem solving and reviewing progress; (5) Dieting and Related Forms of Avoidance: Tackling the three forms of dieting and other forms of avoidance eating; and (6) What Next? Preventing relapse and dealing with other problems.
