Sequencing of symptom emergence in anorexia nervosa, bulimia nervosa, binge eating disorder, and purging disorder and relations of prodromal symptoms to future onset of these disorders.

ABSTRACT: The objective of this study was to characterize the temporal sequencing of symptom emergence for anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD), as well as to test whether prodromal symptoms increase risk for future onset of each type of eating disorder and compare the predictive effects to those of established risk factors. Data from four prevention trials that targeted high-risk young women with body image concerns (N = 1,952; Mage = 19.7, SD = 5.7) and collected annual diagnostic interview data over 3-year follow-up were combined to address these aims. Regarding behavioral symptoms, compensatory weight control behaviors typically emerged first for AN, BN, and PD, whereas binge eating typically emerged first for BED. Regarding cognitiv
