Summary: | Binge eating within binge-eating disorder (BED) is a behaviour widely understood as a response to dietary restraint and emotion dysregulation. However, qualitative literature suggests that a wider range of functions of binge eating exist, with associations between functions of binge eating and adverse childhood experiences highlighted across this research. The present study sought to develop a scale to measure a wide range of functions of binge eating within BED. A secondary aim was to examine the relationship between these functions and adverse childhood experiences (ACEs).
The researchers developed an initial item pool for the Functions of Binge Eating Scale (FBES) and invited experts within the eating disorder (ED) field (n = 22) to review the items. The refined item pool was administered online to adults with self-reported binge eating symptoms (N = 882), along with related measures to establish scale validity.
Exploratory and confirmatory factor analyses produced an eight-factor structure (emotion regulation, hedonic hunger, compensatory eating, numbness/dissociation, emotion expression, self-punishment, control, self-protection). The scale demonstrated good internal reliability and adequate construct and predictive validity. Results also showed that functions theoretically related to childhood maltreatment were predicted by ACEs.
Findings extend our understanding of the range of functions of binge eating experienced in BED. Additionally, findings indicate that type of adverse childhood experience predicts functions of binge eating. Initial validation of the FBES suggests that functions of binge eating are wider than previously understood. Accordingly, clinicians are encouraged to explore and target more complex processes which might perpetuate binge-eating behaviour. |
