The ABCD Study Eating Disorder Symptom Index (EDSI) provides reproducible, item-level decision rules to identify youth with subthreshold and diagnostic-like ED symptom patterns across anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified feeding or eating disorders.
- Why it matters: ED symptoms emerge during adolescence, but ABCD has lacked clinically informed definitions to capture youth at risk for ED-related concerns. Clear, transparent symptom indices are needed to track risk markers and outcomes for earlier intervention.
- What they did: The authors developed EDSI with ED researchers and clinicians, specifying item definitions and decision rules, then compared youth meeting EDSI criteria with those identified using existing ED categorical definitions in ABCD data releases.
- The result: The EDSI framework enables more reproducible, interpretable identification of youth with potentially clinically meaningful ED behaviors, supporting longitudinal analyses of emergence, persistence, and change from adolescence into young adulthood.
