摘要

Pubertal timing is linked to adolescents’ social and behavioral adjustment, yet whether these associations vary across peer contexts remains unclear. This study examined whether group popularity and group social preference moderated longitudinal associations between pubertal timing and aggression among 941 Chinese adolescents (Mage = 12.78, SD = 0.46 years; 46.2% female) followed for one year. Peer groups were identified using Social Cognitive Mapping, and group-level popularity and social preference were derived by aggregating member scores. Multilevel models showed that late-maturing boys exhibited greater relational aggression than on-time boys, an effect amplified in popular groups but attenuated in socially preferred groups. For girls, late pubertal timing was associated with lower overt aggression within socially preferred groups. Findings underscore that peer group status amplifies or attenuates the effects of pubertal timing on aggression in sex-specific ways.
