RemI for Post-Bariatric Surgery Weight Regain
What this study is about
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).
View original scientific description
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).
Primary outcome measures
Weight
Time frame: 12 Months (Assessment points at baseline, 3 Month, 6 Month, 12 Month)
Weight will be measured with a digital scale with participants dressed in light clothes and without shoes. Percent weight loss will be calculated from participants' current weight (at each assessment point) as compared to their baseline weight. Weight will be measured in lbs.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
