Details and patient eligibility

About

The purpose of this research is to conduct a randomized controlled trial (RCT) assessing the impact of CBT on neural responses to binge eating stimuli.

Full description

Females with a BMI>/=25 kg/m2 and BED will be randomized to either a 16-week, one-on-one CBT intervention (n=20) or a waitlist control (WL; n=20). Both groups will have blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) scans at baseline and after the 16-week intervention. During the scans, participants will complete the following tasks: 1) food-specific stop signal task (SST), and 2) script-driven imagery of binge foods.
