Framed within an ecological perspective of the onset of adolescent problem behaviors, the current study explored the joint role of parent-adolescents' relationships and youth's individual factors in binge eating and drinking. Firstly, in line with pieces of research highlighting the beneficial impact of effective parenting on youth development, the present paper sought to enhance the knowledge about the positive influence of parental monitoring on youth's binge drinking and eating. Moreover, since literature evidenced that the explanatory mechanisms of the association between parental monitoring and binge behaviors are not fully explored, the study focused on the potential intervening role of sensation seeking and life satisfaction as mediators. The study design was cross-sectional and self-report questionnaires were administered among a population of 944 high school students (M = 16.35, SD = 1.31) living in Palermo (Italy). Path analysis showed that parental monitoring was directly and negatively related to both binge eating and binge drinking. Moreover, sensation seeking negatively mediated the relationships between parental monitoring and both binge behaviors, whereas life satisfaction only mediated between parental monitoring and binge eating. The current study provided data useful to understand the complex interrelations between intrapersonal (life satisfaction and personality trait, i.e. sensation seeking) and contextual factors (parent-child relationships) that may discourage or cause eating and alcohol use disorders among youth. Finally, implications for parents and practitioners working with youngsters were discussed.
