Long-term implications of childhood and adolescent popularity for social behavior and status in emerging adulthood

Peer status is associated with social functioning throughout childhood and adolescence, but little is known about its’ long-term implications. This study examined longitudinal associations of childhood and adolescent popularity with social behavior and status in emerging adulthood. In line with concurrent associations of popularity with social behavior, we hypothesized that childhood popularity would be associated with a positive, prosocial profile, and adolescent popularity would be associated with a powerful and forceful profile. As research has shown curvilinear associations of popularity with aggression in childhood and adolescence, we also examined whether longitudinal associations were curvilinear. Peer-nominated popularity was measured at 9 and 16 years of age for 118 longitudinal participants. At age 24, they participated in a survey and an online video call session together with three unfamiliar peers, after which everyone in the session rated each other's social behavior. Results showed significant curvilinear associations of childhood and adolescent popularity with emerging adult social behavior and status. Childhood popularity was associated with positive, prosocial behavior and status indicators, showing that in addition to high childhood popularity, also low childhood popularity was associated with higher peer-reported positive, prosocial behavior. High adolescent popularity was associated with both positive, prosocial, and powerful and forceful behavior and status indicators, with especially low adolescent popularity associated with lower levels of these behaviors and status in emerging adulthood. Childhood and adolescent popularity were thus uniquely and differentially associated with social behavior and status in emerging adulthood.
