Mindfulness and compassion-based programs on eating behavior of post-bariatric surgery patients: A two phased clinical trial protocol

Introduction: Weight regain after bariatric surgery remains a relevant and worrisome topic, requiring greater understanding and involvement in research into new adjuvant treatments. This study aims to compare the preliminary effectiveness and feasibility of the Mindfulness-Based Health Promotion and Attachment-Based Compassion Therapy programs as opposed to usual treatments (workshops) on the eating behavior of patients with progressive weight gain after bariatric surgery in Brazilian patients at a private clinic. It was hypothesized that both interventions are feasible and that the self-compassion program may be more effective than the mindfulness program. Methods: The study will be divided into two phases: a cross-analytical study of those who underwent bariatric surgery and a randomized controlled trial only with the ones who had weight regain. Interventions will be conducted for eight weeks synchronously with three assessment points (baseline, post intervention, and 6-month follow-up), both online. The primary outcome will be a change in eating behavior. Secondary outcomes will include improved quality of life, enhanced body image satisfaction and reduced distortion (Brazilian Silhouette Scales for adults), better weight management (maintenance or weight reduction), increased frequency of activity and monitoring with the surgery team. Qualitative data will also be collected by online identification of a sub-sample of participants. Results: Improvements are expected in eating behavior, weight, reverse progressive weight gain, classification of self-image, quality of life, and levels of mindfulness, self-compassion, and anxiety. Conclusion: This study seeks to gather preliminary evidence on the effectiveness of mindfulness and compassion training for the adjunctive treatment of progressive weight gain in post-bariatric patients.
