What this study is about

This national, prospective, multicenter, and randomized study seeks to evaluate the effect of financial incentives on weight loss in individuals who experience weight regain following bariatric surgery. The study also aims to conduct a cost-utility analysis to measure the effectiveness of the intervention and assess the potential budgetary implications if it were to be implemented on a wider scale.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Treatments and study arms

Control

Other

Participants will receive the standard care that includes setting a weight-loss target based on the weight achieved at 12 months post-bariatric surgery following the standard multidisciplinary follow-up at the inclusion center

Threshold financial incentive

Behavioral

Participants will receive the standard care with an additional financial incentive of 300 € if they successfully achieve the weight loss target corresponding to their weight at 12 months after bariatric surgery. This financial incentive will be awarded 12 months after their inclusion in the study.

Proportional financial incentive

Behavioral

Participants will receive the standard care with an additional financial incentive, which will be determined based on the proportion of their actual weight loss in relation to the predefined weight loss target corresponding to their weight at 12 months after bariatric surgery. The financial incentive can be up to 300 € if the weight loss target is achieved 12 months after their inclusion in the study.
