As children enter adolescence, social status within the peer hierarchy gains importance. Variable-oriented research has linked adolescent popularity with both positive and negative adjustment outcomes. Popularity may be better understood with reference to types or subgroups of similar individuals, identified through person-oriented approaches. Resource Control Theory (RCT: Hawley, 1999) posits three distinct types of popular adolescents: coercive, prosocial, and bistrategic. The existence and adjustment correlates of the prosocial and coercive groups have been well-established, but little evidence supports the existence of a bistrategic popular group of adolescents, and even less is known about their adjustment correlates. The present study aims to confirm the existence of the popularity groups hypothesized by RCT and to identify group differences in social adjustment and problem behaviors. A sample of 568 adolescents (n = 288 girls, 280 boys; M age = 12.50) completed peer nomination procedures and self-report questionnaires in the Fall and Spring of the 7th and 8th grades. Longitudinal latent profile analyses classified adolescents into profile groups on the basis of initial physical aggression, relational aggression, and prosocial behavior, and four time points of popularity spanning the 7th and 8th grades. Repeated measures ANOVAs examined profile group differences in social adjustment (peer acceptance, peer rejection, physical victimization, relational victimization, and preference for solitude) and problem behaviors (disruptiveness and delinquency) across the 7th and 8th grades. Results indicate that adolescents fall into one of four distinct groups: aggressive popular, prosocial popular, bistrategic popular, and average. Bistrategic popular adolescents evinced positive social adjustment, exhibiting the highest levels of popularity and peer acceptance and the lowest levels of peer rejection, victimization, and preference for solitude. Despite their social skill advantages, bistrategic popular adolescents were also at risk for problem behaviors. Bistrategic popular adolescents scored above average on problem behaviors, including physical and relational aggression, disruptiveness, and delinquency. Bistrategic popular adolescents successfully navigate the social world in a manner that both offers hope for positive long-term adjustment and concern for the same. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Prior research has shown that both lead users and opinion leaders may propel the diffusion of innovation. This raises the question of whether lead users and opinion leaders are positioned similarly in social networks, which we address using a sample of 23 school classes consisting of 537 children. Research among children is very scarce in this particular domain. Our statistical analyses based on hierarchical linear modeling reveal two general results: first, lead users among children appear to possess a variety of links between clusters; second, opinion leaders are locally positioned within clusters of children and have many direct links.
