Extended Data Fig. 1: KSADS-5 item correlations.

Items indexing lifetime internalizing and eating disorder psychopathology demonstrated moderate to strong postive correlations with one another; however, lifetime emaciation demonstrated weak, negative associations with most items (see Supplementary Table 2 for corresponding p-values). Lifetime self-induced vomiting similarly was nonsignificantly correlated with other items. Correlation values were estimated in the maximum analytic sample for visualization. EMAC = emaciation, OBE = objective binge eating, VOM = self-induced vomiting, OB_FEAR = fear of becoming obese, L_MOOD = low mood, ANHED = anhedonia, WRRY = worry most days, SOC_FEAR = fear of social situations, PHOB = avoidance of phobic object, OBSES = obsessions, COMP = compulsions.
