Inhibitory Control Adult Weight Management

Supplementing Evidence-based Commercial Weight Management Program With Inhibitory Control Training: a Pilot Study

The purpose of this pilot study is to explore the benefits of supplementing the WW (formerly Weight Watchers) online program with a cognitive training game (PolyRules!) among adults with overweight or obesity.

This two-arm pilot study will be used to estimate the effect size in weight loss of supplementing the WW (formerly Weight Watchers) online program with gamified inhibitory control training (PolyRules!) among adults with overweight or obesity. Participants ages 18 and older (n=30) will be randomly assigned to one of two study arms: (1) WW (formerly Weight Watchers) only or (2) WW + Gamified inhibitory control training (PolyRules!). All participants will complete demographic, medical history questionnaires and cognitive assessment battery at baseline/enrollment and after completing the 3-month intervention protocol. All interactions with PolyRules! and WW will be passively recorded to monitor the frequency of interaction with WW and PolyRules!.
