Abstract
Loss of control (LOC) eating is characterized by a reported sense of being unable to control food intake, regardless of the amount of food consumed. It is the hallmark feature of binge-eating episodes, which involve consuming an unusually large amount of food within a discrete time frame, accompanied by a sense of LOC over eating. Some studies investigating the progression of LOC-eating symptoms in children and adolescents suggest that LOC-eating may be a precursor to binge-eating disorder (BED) in adults. To explain the progression from LOC-eating in childhood and adolescence to BED in adulthood, Tanofsky-Kraff and her colleagues developed a theoretical model highlighting three main constructs: negative affectivity, reward sensitivity, and executive functioning. However, a thorough empirical validation of this model has not yet been performed. The current study aims to empirically test Tanofsky-Kraff and her colleagues’ model via structural equation modeling (SEM) and explore potential gender and age differences within this framework. We surveyed 969 adolescents aged 12 to 18 years from the Quebec City area who completed self-report questionnaires. Our findings revealed that both negative affectivity and reward sensitivity are significantly associated with binge-eating symptomatology, whereas self-reported executive functioning is not significantly associated with binge-eating symptomatology. These results support several key components of the proposed model and provide insights into the interactions between the variables when tested simultaneously. Additionally, our study underscores the importance of considering individual factors such as age and gender in understanding binge-eating symptomatology. Some young people feel they can’t control how much they eat, even if they aren’t eating large amounts. This is called loss of control (LOC) eating. Some research suggests that LOC eating in children and adolescents could lead to binge-eating disorder (BED) later in life. To better understand why this might happen, experts have identified three key factors: struggling with negative emotions, being more sensitive to food rewards, and having difficulties with executive functioning. However, this idea hasn’t been fully tested yet. We surveyed 969 teenagers, aged 12 to 18, from the Quebec City area to explore how these three factors might be linked to binge-eating symptomatology. Our results suggest that adolescents who struggle with negative emotions or feel strongly rewarded by food might be at higher risk to report binge-eating symptoms. These findings underscore the importance of teaching young people how to manage their emotions from an early age. The also highlight the differential role of these factors depending on age and gender, which is important for developing more personalized prevention and treatment strategies.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
