Abstract:
Non-adherence to post-operative dietary guidelines contributes to poorer outcomes following bariatric surgery. The current pilot study evaluated the impact of Adapted Motivational Interviewing (AMI) on patients' readiness for change, self-efficacy, and adherence to dietary guidelines following bariatric surgery.A randomized wait-list controlled trial was conducted. Post-operative bariatric patients (N=51) were randomly allocated to receive the single session AMI intervention either immediately (AMI group; n=23), or in 12weeks while continuing to receive standard bariatric care (wait list control [WLC] group; n=28).Completer analyses (n=44) indicated that participants reported improvements in readiness, confidence, and self-efficacy for change immediately following the AMI intervention. They also reported improvements in binge eating symptomatology and some measures of dietary adherence across the 12-week follow-up period. Significant GroupĂ—Time interactions for confidence for change, dietary adherence, and binge eating symptomatology suggest that the AMI group improved on these outcomes whereas the control group did not.These preliminary findings suggest that AMI is an acceptable and feasible intervention with the potential to improve bariatric patients' confidence for change and eating behaviors. Future research should examine these results in comparison to routinely collected postsurgery follow-up data to learn more about AMI's efficacy for improving post-surgical adherence.
