To describe (1) the developmental trajectories of peer victimization from 6 to 17 years of age and (2) the early childhood behaviors and family characteristics associated with the trajectories.
We used data from 1760 children enrolled in the Quebec Longitudinal Study of Child Development, a population-based birth cohort. Participants self-reported peer victimization at ages 6, 7, 8, 10, 12, 13, 15, and 17 years. Participants' behavior and family characteristics were measured repeatedly between ages 5 months and 5 years.
We identified 4 trajectories of peer victimization from 6 to 17 years of age: low (32.9%), moderate-emerging (29.8%), childhood-limited (26.2%), and high-chronic (11.1%). Compared with children in the low peer victimization trajectory, children in the other 3 trajectories were more likely to exhibit externalizing behaviors in early childhood, and those in the high-chronic and moderate-emerging trajectories were more likely to be male. Paternal history of antisocial behavior was associated with moderate-emerging (odds ratio [OR] = 1.54; 95% confidence interval [CI] = 1.09-2.19) and high-chronic (OR = 1.93; 95% CI = 1.25-2.99) relative to low peer victimization. Living in a nonintact family in early childhood was associated with childhood-limited (OR = 1.48; 95% CI = 1.11-1.97) and high-chronic (OR = 1.59; 95% CI = 1.09-2.31) relative to low peer victimization.
Early childhood externalizing behaviors and family vulnerabilities were associated with the development of peer victimization. Some children entered the cascade of persistent peer victimization at the beginning of primary school. Support to these children and their families early in life should be an important component of peer victimization preventive interventions.
描述（1）6 至 17 岁期间同伴侵害的发展轨迹，以及（2）与轨迹相关的儿童早期行为和家庭特征。
我们使用了来自魁北克儿童发展纵向研究的 1760 名儿童的数据，这是一个基于人群的出生队列。参与者在 6、7、8、10、12、13、15 和 17 岁时自我报告了同伴侵害情况。参与者的行为和家庭特征在 5 个月至 5 岁之间反复测量。
我们从 6 岁到 17 岁确定了 4 种同伴侵害轨迹：低（32.9%）、中度出现（29.8%）、儿童期有限（26.2%）和高慢性（11.1%）。与低同伴侵害轨迹的儿童相比，其他 3 种轨迹的儿童在儿童早期更有可能表现出外化行为，而高慢性和中度出现轨迹的儿童更有可能是男性。父亲有反社会行为史与中度出现（优势比 [OR] = 1.54；95%置信区间 [CI] = 1.09-2.19）和高慢性（OR = 1.93；95% CI = 1.25-2.99）相关，而不是低同伴侵害。儿童早期生活在不完整的家庭中与儿童期有限（OR = 1.48；95% CI = 1.11-1.97）和高慢性（OR = 1.59；95% CI = 1.09-2.31）相关，而不是低同伴侵害。
儿童早期的外化行为和家庭脆弱性与同伴侵害的发展有关。一些孩子在小学开始时就进入了持续的同伴侵害的连锁反应。在生命早期为这些孩子及其家庭提供支持应该是同伴侵害预防干预的一个重要组成部分。
