Examining Food-Specific and General Inhibitory Control and Working Memory as Moderators of Relations Between Emotion Regulation Difficulties and Eating Pathology in Adults With Overweight/Obesity: A Preregistered, Cross-Sectional Study.

Abstract

OBJECTIVE Empirical research and theory support the interaction of executive functions (e.g., inhibitory control, working memory) and emotion regulation in guiding goal-oriented behavior; however, applications to eating pathology (e.g., binge eating) are limited. Such research is scant with adults with overweight/obesity (AwO/O), a population reporting high levels of binge eating, emotion regulation difficulties, and deficits in inhibitory control and working memory. We tested interactions between emotion regulation and executive functioning in relation to eating pathology in AwO/O while considering stimuli-specific deficits (e.g., food-specific deficits) in behavioral task performance. METHOD AwO/O (N = 204; MBMI = 32.11; Mage = 38.30 [SD = 12.16]) completed a preregistered, online study assessing demographics and emotion regulation difficulties (Difficulties in Emotional Regulation Scale), inhibitory control (go/no-go task, food and general stimuli), working memory (N-Back Task, food and general stimuli), binge eating (Binge Eating Scale), and disordered eating (Eating Disorder Examination-Questionnaire). RESULTS There was limited evidence of moderation in models examining food-specific and general inhibitory control and working memory, emotion regulation difficulties, and binge eating. Preliminary support was found for emotion regulation difficulties to be more strongly associated with more disordered eating in AwO/O reporting more food-specific and general working memory deficits. Consistent, positive associations between emotion regulation difficulties and eating pathology were observed. CONCLUSIONS Among adults with AwO/O, emotion regulation difficulties are closely related to eating pathology, regardless of performance on working memory and inhibitory control tasks. Clinicians and researchers working with AwO/O may consider how emotion regulation difficulties and working memory deficits work together to influence disordered eating.
