Low Maternal Care and Protection and Body Image Dissatisfaction as Psychopathological Predictors of Binge Eating Disorder in Transitional-Age Youth

Background: Binge eating disorder (BED) frequently arises during the transitional age (18–25 years), a critical developmental period characterized by challenges in autonomy, identity formation, and interpersonal functioning. This study investigated psychopathological predictors of BED risk in this age group, with particular focus on parental bonding, attachment style, body dissatisfaction, alexithymia, and depressive symptoms. Methods: A total of 287 participants aged 18–25 years completed the Binge Eating Scale (BES), Beck Depression Inventory-II (BDI-II), Body Shape Questionnaire (BSQ), Toronto Alexithymia Scale (TAS-20), Attachment Style Questionnaire (ASQ), and Parental Bonding Instrument (PBI). Sociodemographic information and body mass index (BMI) were also collected. Results: Compared with non-BED risk groups, individuals at risk of BED exhibited significantly higher BMI, greater alexithymia, higher body dissatisfaction, more insecure attachment patterns, and lower recalled paternal and maternal care. Hierarchical binary logistic regression revealed that the final model explained 56.1% of the variance (Nagelkerke R2) and correctly classified 92.1% of cases. Significant predictors of BED included body dissatisfaction, elevated BMI, low maternal care, and low maternal protection. Conclusions: This study is the first to examine BED risk factors specifically during the transitional age. Findings indicate that body image dissatisfaction, higher BMI, and inadequate maternal emotional care and protection are salient predictors at this life stage. Preventive interventions should integrate parental psychoeducation, nutritional guidance, and therapeutic strategies addressing both eating disorder symptoms and attachment-related difficulties to reduce BED onset and improve psychosocial outcomes in emerging adults.
