    Author: Wong VZ, Christian C, Levinson CA.
    Journal: Eat Behav; 2021 Dec; 43():101560. PubMed ID: 34492594.
    Abstract:
    OBJECTIVE: Repetitive negative thinking (RNT) is associated with eating disorder (ED) symptoms, but few studies have evaluated how RNT may relate to specific ED behaviors (e.g., fasting, binge eating). Furthermore, little research has examined RNT in adolescent girls, a critical population for ED development. Concern over mistakes perfectionism (i.e., preoccupation with and overvaluation of errors) and social appearance anxiety are transdiagnostic risk factors for EDs that may be amplified by RNT, contributing to the development of ED behaviors. METHOD: The current study (N = 332 female high school students) explored RNT in an adolescent sample and tested whether RNT was uniquely associated with fasting/binge eating and moderated the relationships between social appearance anxiety/perfectionism and fasting/binge eating. RESULTS: RNT was not associated with fasting and did not significantly moderate the relationship between social appearance anxiety/perfectionism and fasting. RNT was positively associated with binge eating but did not moderate the relationship between social appearance anxiety/perfectionism and binge eating. CONCLUSIONS: RNT may contribute differentially to specific ED behaviors such as fasting and binge eating during ED development. If replicated in prospective data, these findings suggest targeting RNT in adolescence may decrease binge eating.
