ObjectiveEarly adolescence is marked by elevated psychopathology, including disrupted eating attitudes and behaviors. Reward processing is an identified mechanism in portending eating pathology, that is, aberrant reward responsivity may contribute to disrupted reward‐seeking behaviors (e.g., food consuming). This literature has focused on adults or mid‐to‐late adolescents, with little work done on early adolescence. We examined the linkages between reward feedback processing, indexed by event‐related potentials (ERPs), and changes of emerging disordered eating in community‐dwelling early adolescents.MethodAt T1, 115 youths (66 girls, mean/SD age = 11.00/1.16 years) completed an EEG monetary reward Doors task. Youths completed the Eating Disorder Examination‐Questionnaire Short at T1 and ~6 months (T2) and ~12 months (T3) after T1. In the ERP data, we isolated a reward positivity (RewP) and a late positive potential (LPP) via principal component analysis. We applied multilevel modeling to examine whether baseline ERPs interacted with Time in predicting disordered eating and whether these interactions varied by sex.ResultsWe found a significant Time × LPP interaction in girls but not boys. Among girls, only those with a smaller LPP toward the losses (versus wins), which might reflect suboptimal evaluation and regulatory processes in undesired situations, showed increases in disordered eating from T1 to T3.DiscussionWe provided preliminary yet novel evidence concerning the prospective associations between reward processing and changes of disordered eating in early adolescents. Future studies along this line will be critical for understanding the early mechanisms of eating pathology, identifying youths at risk, and developing prevention strategies.

ObjectiveEvidence suggests that interpersonal stress plays a role in maintaining binge eating and purging (e.g., self‐induced vomiting, misuse of laxatives). Stress is especially likely to promote engagement in maladaptive behaviour if the behaviour is habitual; therefore, individuals whose binge eating and/or purging are habitual may be particularly likely to engage in these behaviours in the context of interpersonal stress. We aimed to investigate this hypothesis in a sample of women with binge eating and/or purging using ecological momentary assessment (EMA).MethodWomen (N = 81) with binge‐eating and/or purging symptoms completed a self‐report measure assessing habit strength of binge eating and purging followed by a 14‐day EMA protocol assessing daily perceived interpersonal stress and binge‐eating and purging episodes.ResultsHabit strength of purging moderated the within‐person effect of interpersonal stress on purging frequency, such that higher daily stress was associated with greater same‐day purging frequency when purging was more habitual. Contrary to expectations, the interactive effect of habit strength of binge eating and daily interpersonal stress on same‐day binge‐eating frequency was non‐significant.ConclusionsFindings suggest that individuals with habitual purging may be vulnerable to engaging in purging when they are experiencing high levels of interpersonal stress.
