## TL;DR

This study explores how emotions and emotion regulation influence eating behaviors in adults, focusing on the role of positive and negative affect.

## Contribution

The study investigates the mediating role of emotion regulation in the relationship between affect and eating behavior in non-clinical populations.

## Key findings

- Negative affect is significantly linked to maladaptive eating behavior and emotion regulation difficulties.
- Positive affect is negatively related to emotion dysregulation but does not directly predict disordered eating behavior.
- Emotion regulation does not mediate the relationship between affect and maladaptive eating behavior.

## Abstract

Background: Emotions substantially influence human eating behavior, but while negative affect has been consistently associated with maladaptive eating patterns, the role of positive affect remains underexplored. Thereby, emotion regulation (ER) is considered a key mechanism through which affective states may influence eating behavior. However, its mediating role remains unclear, particularly among non-clinical populations. Objectives: This study aimed to investigate the potential mediating role of ER in the relationship between negative and positive affect and maladaptive eating behavior in a non-clinical adult sample. Methods: This cross-sectional online survey was administered to a general-population convenience sample of 189 adults. Participants completed four standardized self-report questionnaires: Eating Attitudes Test (EAT-26), Positive and Negative Affect Schedule (PANAS), Difficulties in Emotion Regulation Scale (DERS-36), and Depression Anxiety Stress Scale (DASS-21). Correlational analyses and multiple regression models were used to examine the relationships between variables and to test the mediating role of ER. Results: Negative affect was significantly associated with both maladaptive eating behavior (r = 0.29, p < 0.01) and ER difficulties (r = 0.51, p < 0.01). Positive affect was only negatively related to emotion dysregulation (r = −0.47, p < 0.01). ER did not mediate the relationship between either positive or negative affect and maladaptive eating behavior. Conclusions: Findings underscore the influence of negative affect in maladaptive eating behavior, independently of ER. Although positive affect did not directly predict disordered eating behavior, its association with reduced ER difficulties warrants further exploration of its potential protective role.
