The Investigation of a Remotely Delivered Behavioral Intervention for Postoperative Weight Regain
This project aims to evaluate a newly developed Internet-delivered (via e-learning modules)
acceptance-based behavioral intervention (ABTi) for individuals who are experiencing weight
regain after bariatric surgery. Specifically, the investigators aim to assess ABTi's efficacy
on stopping and/or reversing weight by comparing it to a wait-list control (WLC) condition.
The investigators also aim to evaluate its effect on targeted weight control behaviors and
acceptance-based skills. Finally, the investigators will examine the relationship between
weight outcomes and changes in process variables through exploratory analyses. Treatment
outcomes (i.e., weight, maladaptive behaviors, physical activity, acceptance-based skills)
will be measured at assessments pre-, mid-, and post-treatment, as well as at 3 months after
treatment has ended.
Primary Aims.
1. To test the hypothesis that participants randomly assigned to ABTi will display greater
weight loss from pre- to post-treatment than those assigned to WLC.
2. To test the hypothesis those receiving ABTi, compared to WLC, will display decreased
maladaptive eating behaviors (i.e., loss of control episodes, grazing, emotional eating,
disinhibition), increased physical activity, and greater improvements in
acceptance-based skills (i.e., mindfulness, defusion, food-related acceptance).
Exploratory Aim.
(1) To assess if changes in acceptance-based skills, maladaptive eating behaviors, and
physical activity are associated with pre- to post-treatment weight outcomes.
