Exploring the Relationship Between Disordered Eating and Executive Function in a Non-Clinical Sample

Abstract

Previous research suggests that individuals diagnosed with eating disorders (ED) may experience executive functioning deficits that help maintain their ED. Although this relationship is reported consistently in clinical samples, it is important to consider whether it holds for individuals with sub-clinical ED symptoms. One hundred eighty-eight university students participated in the present study examining the relationship between executive function (EF) and disordered eating behaviors. Participants completed a demographics questionnaire, self-report questionnaires measuring atypical eating behaviors (EAT-26; EDI-3), and a self-report measure of EF (BRIEF-A). Correlational analyses demonstrated significant positive associations between ED behaviors and problems with emotional control, shifting, inhibition, and self-monitoring. Six hierarchical multiple regressions were conducted, using EF scores to predict scores on EAT-26 subscales (Dieting, Bulimia, Total ED Risk) and EDI-3 scales (Drive for Thinness, Bulimia, Risk Composite). In all regression analyses, BRIEF-A Emotional Control emerged as a significant predictor. As would be expected, EDI-3 Bulimia scores were also predicted by problems with inhibition. These results provide preliminary evidence of an association between non-clinical patterns of disordered eating and executive dysfunction, specifically including the ability to control one's emotions, suggesting that emotional control problems may help predict ED risk. Future research could examine how these factors predict the development of eating disorders.
