Abstract
Although there is ample evidence linking academic and behavioral domains, few studies have examined the long-term, varied impacts of academic performance trajectories on problem behavior outcomes, particularly in early and middle adolescence. This study examined the different three-year academic performance trajectories, their links with behavioral outcomes, and the demographic and educational predictors that distinguish these patterns. The sample consisted of 10,279 Chinese adolescents (46.43% girls; Mage = 12.97 years, SD = 0.89). Three trajectory groups emerged: Moderate Start with Steady Growth (45.93%), High Start with Accelerated Growth (36.89%), and Low Start with Minimal Growth (17.17%). Demographic and educational factors (i.e., age, parents’ education, family income, family size, school climate, rank, and sector) predicted group membership. The High Start with Accelerated Growth group exhibited fewer externalizing problems than the other groups. The results underscored the differences in academic performance trajectories and their associations with the predictors and outcomes of problem behaviors, which has implications for academic and behavioral development.
