A453 Personalized, Multi-Component Interventions for Behavioral Weight Management: Yes, but How? A Hybrid Intervention of Compulsory and Personalized Elements Based in Self-Determination Theory

Abstract

Bariatric surgery is the most effective treatment for severe obesity. However, with more than 40% of postoperative bariatric patients experiencing excessive weight regain (i.e., 25%+ of total lost weight) and the majority of patients regaining some weight, there is a need for individualized behavioral interventions to promote sustained, lifelong maintenance of surgical weight loss. Given the multifactorial nature of weight regain, interventions must be multicomponent and personalized. This recommendation represents best practice; however, clinicians may lack knowledge or experience for pragmatic implementation. This session will address these issues, highlighting self-determination theory (SDT) as optimal for conceptualizing personalized treatments. Emphasis will be placed on the utility of the three components of SDT – autonomy, competence, and relatedness – to inform personalized, holistic interventions for patients who have lost or are trying to lose weight. SDT-based, personalized behavioral interventions can be tailored for both surgical and non-surgical populations with obesity, and they are ideal for preventing recidivism following weight loss. A brief overview of the BOSS intervention (Bariatric Outcomes: Sustaining Success) will be provided: this is an SDT-based, multicomponent intervention for promoting sustained weight loss and preventing recidivism. Five adult case examples will highlight how the intervention is tailored across SDT domains of autonomy, competence, and relatedness. Preliminary outcome data will also be provided: all patients are actively losing weight or maintaining weight loss. The session will demonstrate the implementation and personalization of evidence-based interventions, emphasizing the need for both compulsory and individualized elements within a multi-component program for lifelong behavioral weight management.
