Positive Psychology & Motivational Interviewing for Post-Bariatric Surgery

(GOALS Trial)

This trial explores whether a combination of positive psychology and motivational interviewing, known as Positive Psychology-Motivational Interviewing, can increase physical activity in individuals who have undergone bariatric surgery. The study compares this approach to a control group receiving general physical activity information and a Fitbit. Ideal participants are adults who had bariatric surgery 6-12 months ago, wish to become more active, and currently engage in less than 200 minutes of moderate to intense exercise weekly. Participants should also be comfortable using a phone and speaking English to join the sessions. As an unphased trial, this study provides a unique opportunity to explore innovative methods to enhance physical activity post-surgery.

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

Research has shown that positive psychology and motivational interviewing (MI) are safe and well-received. In past studies, participants attended 85% of the sessions, indicating that this approach is both feasible and liked. People rated the sessions highly, with scores over 8 out of 10 for being helpful and easy to understand, suggesting that most found the sessions useful and simple to follow.

Motivational interviewing is particularly known for its supportive and non-judgmental nature. It aims to increase motivation without being pushy or making participants feel uncomfortable, creating a welcoming environment.

Researchers are excited about using Positive Psychology and Motivational Interviewing for post-bariatric surgery patients because this approach focuses on enhancing mental well-being and motivation, rather than just physical recovery. Unlike traditional post-surgery care that often emphasizes physical exercise through general recommendations, this method incorporates psychological skills to boost positive emotions and motivation during physical activity. Additionally, the use of a Fitbit to set personalized activity goals makes the approach highly individualized, aiming to improve adherence and long-term success in maintaining a healthy lifestyle. This mental and motivational focus offers a fresh perspective that could significantly enhance patient outcomes beyond what standard care achieves.

Research has shown that combining positive thinking with motivational conversations can help individuals who have undergone weight-loss surgery become more active. In this trial, participants in the Positive Psychology-Motivational Interviewing Intervention arm will engage in these activities. Studies indicate that these methods can lead to better control over eating habits and adherence to healthy routines. Specifically, participants in similar activities reported fewer binge eating episodes and better diet adherence over 12 weeks. Additionally, focusing on positive feelings may help patients overcome emotional challenges, making it easier to stay active and maintain weight loss. Overall, this approach could increase motivation and support long-term health improvements after surgery.³⁶⁷⁸⁹
