Registration Number

Lead Sponsor
University of Manchester
Brief Summary

The aim of the present research is to test the effect of helping people to reward themselves when they have successfully lost weight and the impact this will have on subsequent weight. Each participant will be randomly allocated to one of four conditions. The trial requires 200 participants to perform a fully powered statistical analysis. The four conditions are: (1) a control condition, (2) intervention 1 (form a single self-incentivising implementation intention from a drop-down menu), (3) intervention 2 (form multiple self-incentivising implementation intentions from a drop-down menu), or (4) intervention 3 (asked to form a single self-incentivising implementation intention of their own devising). The main outcome measure will be BMI, which will be self-reported.
