童年晚期至青少年早期攻击和同伴侵害的关系:交叉滞后研究

采用整群抽样法抽取2178名小学生为被试（平均年龄11.05±0.69岁，男生1132人）自5年级追踪至8年级，通过纵向交叉滞后模型对攻击与同伴侵害间的关系进行考察。结果发现，各年级关系攻击均可预测之后的关系侵害，7年级身体攻击预测8年级身体侵害，此外6年级关系侵害经历对7年级关系攻击具有预测作用。攻击与同伴侵害间的纵向联系不存在性别差异。这些结果表明，童年晚期至青少年早期攻击与同伴侵害之间总体上符合连续性社交过程模型，即攻击对随后的同伴侵害具有更明显预测作用，但在小学升初中的学校过渡阶段关系侵害预测随后的关系攻击，部分支持两者间存在双向关系。该结果提示需关注儿童青少年的攻击与同伴侵害经历，采取措施避免其陷入攻击与同伴侵害间的恶性循环之中。

The Bidirectional Associations between Aggression and Peer Victimization from Late Childhood to Early Adolescence: A Cross-lagged Study

In a sample of 2178 children (M_age=11.05, SD_age=0.69 years, 1132 boys) who were recruited from 14 elementary schools and followed from grade 5 to grade 8, the current study examined the cross-lagged longitudinal associations between aggression and peer victimization. The results revealed that relational aggression at grade 5, 6, and 7 predicted increases in relational victimization 1 year later, physical aggression at grade 7 predicted increases in physical victimization at grade 8, and experience of relational victimization at grade 6 predicted increases in relational aggression at grade 7. These results did not differ across gender. The results indicated that the longitudinal association between aggression and peer victimization was generally consistent with a sequential model stating that aggression predicts later experience of peer victimization, while at the same time partially supported the bidirectional association between aggression and peer victimization. The finding had implications for intervention and prevention of children's aggression and victimization.
