We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of Swedish adolescents (N = 1,515, 51% girls, $\overline{X}$_age at T1 = 13.0 years). The results revealed negative developmental trends for peer victimization and offending. Early pubertal timing was linked to higher initial levels and a steeper decrease of peer victimization and offending. The only effect of pubertal timing that differed between the genders was that the initial level of offending was stronger for boys than girls. In conclusion, the negative impact of early pubertal timing on peer victimization and offending occurs in the early stages of adolescence and disappears thereafter.

我们通过研究青春期时机在同龄人受害和青春期初期到中期的发展轨迹中的作用，利用潜伏增长曲线分析扩展了青春期早期与不良同伴关系之间关联的研究。我们利用了每年从一组瑞典青少年中收集的三波纵波数据（N = 1,515，其中51％是女孩，$\overline{X}$T1的_年龄= 13.0岁）。结果显示同伴受害和犯罪的消极发展趋势。青春期的早期时机与较高的初始水平以及同伴受害和犯罪的急剧减少有关。性别不同，青春期时机的唯一影响是男孩的初始犯罪水平强于女孩。总之，青春期早期对同伴受害和得罪的负面影响发生在青春期的早期，并在此后消失。
