Abstract
By investigating the impact of dark personality traits on adolescent health, this study explores the interplay among economic disadvantage, spectator sports involvement, and cyber victimization. We analyzed data from 1844 students aged 13-17 in a school district in the USA, and our findings reveal positive associations between economic disadvantage and both Machiavellianism and psychopathy, influencing negative emotions-driven eating. Spectator sports engagement exhibits links with Machiavellianism and narcissism, suggesting potential drawbacks to competitive behaviors. Cyber victimization shows associations with psychopathy and negative emotions-driven eating. The results illuminate the dynamic associations between emotional eating and health outcomes, including BMI and perceived quality of life. These findings deepen our understanding of how dark personality is shaped and subsequently influences adolescents' well-being, offering insights for targeted interventions.
