Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this investigation is to identify the potentially crucial role of anticipatory reward mechanisms maintaining bulimic behavior (i.e., binge eating and purging) in bulimia nervosa (BN). The research will investigate neural and psychological anticipatory processes in BN, both in the scanner and the natural environment.
