Comparing a Group-based Guided Self-help Approach to Pure Self-help for the Treatment of BED
Binge Eating DisorderBinge eating disorder (BED) is the most common eating disorder in adults, affecting 2.8% of the population. The disorder is characterized by recurrent episodes of binge eating which are not followed by inappropriate compensatory behaviours such as self-induced vomiting. BED is associated with an increased risk of health complications, significant impairment to social and occupational functioning, and reduced quality of life. Despite the negative consequences associated with this disorder, standard therapy for BED is often inaccessible and costly. To address the limitations of standard therapy for BED our research team has developed Binge Focused Therapy (BFT) as an innovative, guided self-help approach to BED treatment. BFT was derived from elements of "The Brain Over Binge Recovery Guide" by Kathryn Hansen, which incorporates fundamental aspects of Acceptance and Commitment Therapy, Dialectical Behaviour Therapy, Motivational Enhancement Therapy, and addictions treatment. We further streamlined this approach into a protocol that can be delivered by non eating disorder specialists (e.g., honours psychology students, nurses, occupational therapists). In 2018, our research team conducted a proof-of-concept pilot study with a sample of 40 individuals with BED. Unpublished results of this uncontrolled study indicated that the sample experienced significant reductions in binge episodes per month, binge eating severity, general eating disorder symptomology, and improved confidence in changing binge eating behaviours. Although the results from this small, uncontrolled, proof-of-concept study are encouraging, qualitative and quantitative data highlighted several aspects of the BFT intervention that could be altered and tested in a randomized controlled trial that compares BFT to an active comparator.
Repetitive Transcranial Magnetic Stimulation of the DMPFC for Anorexia and Bulimia: an Open-Label...
Bulimia NervosaAnorexia NervosaThis project proposes to perform a pilot study of fMRI targeted Dorsomedial Prefrontal Cortex repetitive transcranial magnetic stimulation (DMPFC-rTMS) on individuals diagnosed with Bulimia Nervosa (BN) and Anorexia Nervosa (AN). The DMFPC is a novel target for rTMS, is heavily implicated in the regulation of mood and affect, and has been suggested to be involved in AN, BN, major depression, OCD, and PTSD. Improved function in this area might lead to reduced AN and BN symptoms, such as bingeing, purging, and over-activity, perhaps by improved regulation of mood and affect. Improvements in important areas of comorbidity might allow for better response to intensive treatment for AN and BN, and reduce relapse rates after such treatment. The DMPFC may be a more appropriate target for compared to the Dorsolateral Prefrontal Cortex (DLPFC), which has typically been the focus of stimulation in the past. Our initial preliminary pilot work has noted unexpected and significant improvements in some core ED symptoms (bingeing and purging) and in important areas of comorbidity (OCD and PTSD), along with expected improvements in mood. These changes have allowed some treatment resistant patients to either complete intensive treatment or be successful in maintaining their progress post intensive treatment. Subjects will receive up to 30 sessions of bilateral DMPFC-rTMS. Response will be evaluated clinically, via psychometric measures, and pre and post fMRI.
Pilot Intervention for Social Biases in Eating Disorders
Eating DisordersAnorexia Nervosa2 moreBoth behavioral, psychological, and cognitive differences related to social cognitive function have been related to illness-state in eating disorders, but interventions that directly target these problems are limited. This pilot intervention explores whether a brief art-therapy team-building intervention coupled with psychoeducation about social behavior can change self-concept or clinical symptoms in patients with eating disorders. Participants will complete pre-treatment assessments related to social behaviors and clinical symptoms, attend four two-hour group sessions, and provide two follow-up post-treatment assessments at 1-4 weeks after the treatment and 3-5 months later. Comparisons between the pre-intervention data and the first follow-up will be the primary outcome measures. The primary hypotheses are that participants will show increases in self-esteem and positive self-attributions and decreases in eating disorder symptoms after the intervention. The secondary hypothesis is that other clinical symptoms (depression, anxiety) will be improved after the intervention. Feedback from participants about their experience with the study will assess perceived benefits as well as acquisition of the psychoeducation targets.
Integrative Cognitive-Affective Therapy for Binge Eating Disorder
Binge Eating DisorderThe purpose of the study is to test a newly developed individual psychotherapy treatment for binge eating disorder in adults. This treatment is a type of individual psychotherapy called Integrative Cognitive-Affective Therapy (ICAT) that focuses on helping people change their behaviors, feelings, thoughts about themselves, and relationships. This new treatment is being compared to an existing treatment called Cognitive-Behavior Therapy-Guided Self Help (CBTgsh), which focuses on changing behavior patterns through the use of reading and homework assignments along with sessions with a therapist. The primary hypothesis of this investigation is that ICAT will be associated with greater reductions in binge eating at end of treatment and follow-up compared to CBTgsh.
Treatment for Obesity and Binge Eating Disorder
Binge Eating DisorderObesityThis study is a test of cognitive behavioral therapy(CBT) and behavioral weight loss (BWL) treatments for obese patients with binge eating disorder (BED). The study involves a comparison of three treatment conditions: (1) CBT; (2) BWL, and (3) a sequential (two-part) treatment consisting of CBT followed by BWL.

An Integrative Intervention for Loss of Control Eating Among Adolescent Girls
Binge Eating/Loss of Control EatingThis study aims to develop a manualized and culturally sensitive intervention for adolescent girls targeting binge and loss of control (LOC) eating. The investigators will evaluate the feasibility and acceptability of the intervention in a controlled pilot trial. The investigators hypothesize that this intervention will serve to reduce binge and LOC eating, as well as improve psychosocial functioning as evidenced by decreased depression, anxiety, eating disorder cognitions, and impulsivity, and improved quality of life.
