RemI for Post-Bariatric Surgery Weight Regain

Summary

The goal of this clinical trial is to test the effectiveness of remotely-delivered interventions (utilizing acceptance-based behavioral treatment skills (ABTi)) amongst bariatric surgery populations who are experiencing weight regain postoperatively (\> 5% from their lowest postoperative weight and after postoperative Month 6). Investigators aim to evaluate ABTi's efficacy for reversing weight regain and its effect on targeted weight control behaviors and weight-related comorbidities by comparing participants randomly assigned ABTi (n = 100) to those assigned to a Control group that also receives brief phone calls but that focus on reiterating instruction on the dietary and behavioral changes required of surgery and initially taught preoperatively (C, n = 100).

The main research aims are:

1. To compare changes in body weight over 12 months in 200 bariatric patients who have regained \> 5% of their weight and are randomly assigned to ABTi or Control.
2. To compare changes in eating behaviors (i.e., caloric intake, frequency of maladaptive eating behaviors), physical activity, and weight-related comorbidities (i.e., biomarkers of diabetes, hypertension) over 12 months in the two groups.
3. Exploratory - To test ABTi's theoretical mechanisms of action, including a) effects of theory-based active ingredients (i.e., acceptance, defusion, values clarity, mindfulness) on weight outcomes and b) changes in impact of internal states (i.e., hunger, cravings) on eating behavior.

Interventions

BEHAVIORAL

Acceptance-Based Behavioral Intervention

Intervention will evaluate acceptance-based behavioral treatment (ABT) for individuals who are experiencing weight regain after bariatric surgery. ABT builds acceptance and mindfulness skills that increase the capacity to experience uncomfortable internal states (e.g., food cravings, hunger, negative affect). Online treatments include video modules demonstrating session content as well as interactive features. These interventions are particularly desirable, reduced participant burden, and are cost effective. ABT provides patients unique skills that directly target causes of dietary non-adherence. ABT provides patients specialized skills to directly target causes of dietary nonadherence (rather that solely repeating behavioral strategies they received during preoperative medical weight management required by their third party payers and bariatric surgery programs).
