Positive Self-Beliefs as a Mediator of the Relationship Between Adolescents’ Sports Participation and Health in Young Adulthood

The present study examined the relationship between participation in sports during adolescence and physical activity and subjective health in young adulthood. A sample of 8,152 (males = 50.8%, females = 49.2%) adolescents from the National Longitudinal Study of Adolescent Health were used. Results of the study showed that participating in an organized sport during adolescence was associated with higher levels of physical activity and better subjective health during young adulthood after controlling for participation in general physical activities (e.g., jogging, biking, skateboarding) during adolescence. Participation in sports during adolescence was associated with more positive self-beliefs 1 year later that, in turn, were associated with higher levels of moderate to vigorous physical activity and better subjective health 6 years later. Results suggest that positive self-beliefs partially mediate the relationship between adolescents’ participation in sports and two health outcomes in young adulthood: moderate to vigorous physical activity and subjective health. Findings highlight the utility of youths’ participation in organized sports for promoting healthy outcomes. Implications for policy and practice are discussed.

Pathways from Childhood Adversity to Problem Behaviors in Young Adulthood: The Mediating Role of Adolescents’ Future Expectations

Adverse childhood experiences and pessimistic future expectations about college attendance or mortality are established risk factors for problem behaviors among youth. Data were from the National Longitudinal Study of Adolescent to Adult Health (N?=?14,800; 49?% female). Participants were 11–17-years-old at baseline and 24–32-years-old at outcome. Adolescents’ college expectations and fatalistic expectations mediated the effect of childhood adversity on violent behavior in young adulthood. Neither college nor fatalistic expectations were significant mediators in models predicting substance use and nonviolent antisocial behaviors. Although observed mediational effect sizes were small, they survived models that included multiple controls designed to rule-out alternative explanations. Intervening on adversity-exposed adolescents’ college and fatalistic expectations may reduce risk for violent behaviors.
