Summary

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.

BEHAVIORAL

Acceptance Based Behavioral Intervention

This intervention focuses on acceptance-based strategies with an emphasis on willingness to experience less pleasurable internal experiences (e.g., pleasure from eating calorically-dense foods) and aversive internal experiences (e.g., hunger, food cravings). Strategies to increase this willingness will be taught, including defusion (i.e., getting psychological distance from internal experiences to allow oneself to act independently of them). Mindful decision-making, as it relates to eating and exercise, will also be emphasized. Clarification and commitment to core values is another key component, as living life in accordance with one's values (e.g., health) makes willingness to make difficult choices worthwhile. Standard behavioral techniques for weight loss (i.e., self-monitoring, stimulus control, psychoeducation) will also be included.
