Working Memory and Inhibition as Mediators in the Relationship Between Adverse Childhood Experiences and Emotional Eating.

Abstract

Objective: Previous studies have focused on the dual relationship among adverse childhood experiences (ACEs), cognitive abilities, and emotional eating. The current study aims to test the mediating role of executive functioning (working memory and inhibition) between ACEs and emotional eating. Methods: A total of 1105 community-based participants, aged 18-45 (Mean = 26.28, SD = 7.09), were included in the study. Among the participants, 698 (63.16%) were female, and 407 (36.84%) were male. Participants completed the Childhood Trauma Questionnaire; the Adult Executive Functioning Inventory; the Dutch Eating Behaviour Scale; the Life Events Checklist; and the Depression, Anxiety, Stress Scale Short Form. Multiple mediation analyses were employed using MPlus 8.3. Results: Multiple mediation analysis results showed that working memory and inhibition mediate the relationship between ACEs and emotional eating. Furthermore, working memory and inhibition were positively correlated with emotional eating. Discussion: Our findings indicate that difficulties in working memory and inhibition may increase the risk of emotional eating. Early intervention targeting executive functions may prevent emotional eating. Public Significance: Our findings highlight the relationship among ACEs, executive functioning, and emotional eating. Intervening in executive function may have clinical benefits for individuals with ACEs.
