Summary

This study looked at how certain personality traits and brain activity are linked to eating disorder symptoms in teenage girls. Researchers used brain scans to measure responses to rewards and followed up one year later to see how symptoms changed. The goal was to better understand the biology behind eating disorders, not to test a treatment.
