Implementing an Interdisciplinary Eating Disorder Screening and Treatment Program for Post-Bariatric Surgery Patients in Nova Scotia

The goal of this interventional study is to evaluate the Treatment and Evaluation for After Metabolic Surgery with Eating Disorders (TEAM-ED) program, which combines streamlined access to screening, diagnostic assessment, and treatment with an interdisciplinary team approach to treatment planning, for managing disordered eating in adults who have recently had weight loss surgery in Nova Scotia. The main question it aims to answer is 'can an interdisciplinary program for identifying and managing disordered eating after weight loss surgery be implemented in Nova Scotia? This study will determine the feasibility and impact of the TEAM-ED program by assessing the following objectives: 1. Reach (how effectively the program engages the target population \[post-weight loss surgery patients\]) 2. Effectiveness (the extent of the program's impact on key clinical outcomes related to disordered eating and weight management) 3. Adoption (the extent to which the program is adopted and accepted by clinicians) 4. Implementation (how consistent program delivery is and factors impacting consistent delivery) Participants will complete a disordered eating screening questionnaire online every 3 months after weight loss surgery until they reach 18-months post-surgery. Participants found to have disordered eating will be referred to the Nova Scotia Provincial Eating Disorder Service (NSEDPS) for standard disordered eating treatment (brief cognitive behavioral therapy \[CBT-T\]) plus treatment plan oversight by both weight loss surgery and eating disorder specialists. Standard outcome measures will be collected at baseline, during eating disorder treatment, post-treatment, and at follow-ups. Participants may also be asked to do a one-on-one research interview about their experiences with the program.

Inclusion Criteria: * ≥19 years old * Between 3- and 18-months post-weight loss surgery. * Able to complete English computer-based self-report questionnaires (with adequate accommodation, if necessary).
