This study examined the associations between children's co-occurring relational and physical aggression trajectories and their peer relations (i.e., peer rejection, peer acceptance, and reciprocated friendships) from late childhood (Grade 4; Mage = 10.0) to early adolescence (Grade 8; Mage = 13.9). Using a sample of 477 children (240 girls), the findings indicated there were multiple heterogeneous subgroups of children who followed distinct co-occurring aggression trajectories. For each of these subgroups, multiple indices of their relational development were assessed and findings revealed notable group differences. These results have implications about the potential costs and benefits of aggression, and how its associations with children's peer relationships may vary as a function of aggression subtype, developmental timing, and gender.
本研究考察了童年晚期（四年级；平均年龄=10.0岁）至青春期早期（八年级；平均年龄=13.9岁）儿童同时出现的关系攻击和身体攻击轨迹与其同伴关系（即同伴拒绝、同伴接纳和互惠友谊）之间的关联。以477名儿童（240名女孩）为样本，研究结果表明，有多个不同的儿童亚组遵循不同的同时出现的攻击轨迹。对于这些亚组中的每一组，都评估了其关系发展的多个指标，结果显示出显著的组间差异。这些结果对于攻击行为的潜在成本和收益，以及其与儿童同伴关系的关联如何随攻击亚型、发展时机和性别而变化具有启示意义。
