Self-Esteem and Binge Eating among Adolescent Boys and Girls: The Role of Body Disinvestment

Abstract

Although low self-esteem and body disinvestment have been recognized as potential risk factors for disordered eating, no studies have explored how these factors may work together to predict binge eating in adolescents. Therefore, we hypothesized a path model for girls and boys separately to investigate whether the body’s investment dimensions (feelings towards the body, physical touch, body care, body protection) mediate the relationship between self-esteem and binge eating, and age moderate such relationships. Participants were 1046 Italian students aged between 11 and 19 years (472 girls, Mage = 14.17; 574 boys, Mage = 14.60) screened through self-report measures. Both models showed an acceptable fit (males: χ2(22) = 30.441; RMSEA = 0.026; CFI = 0.99; TLI = 0.97; SRMR = 0.023; females: χ2(22) = 34.723; RMSEA = 0.35; CFI = 0.98; TLI = 0.95; SRMR = 0.029). Negative body feelings and reduced body protection fully mediated the relationship between self-esteem and binge eating, regardless of gender. Our findings highlight the importance of interventions promoting body emotional investment to reduce adolescents’ vulnerability to binge eating.
