尽管关系攻击的研究在文献中越来越受到关注，但人们对这种行为的根本原因以及各种信息提供者的相对有效性知之甚少。这些问题在 1,981 对 6 至 18 岁双胞胎样本中得到解决（36% 为女性，34% 为男性，30% 为异性）。通过结构化访谈通过母亲和自我报告来评估关系攻击性。单变量模型估计了知情者对遗传和环境的影响，并检查了性别差异的证据。心理测量模型结合了两位受访者的数据来估计受访者共有的和特定受访者的病因影响。在两性中，反映母亲和孩子对孩子关系攻击行为的共同看法的潜在变量在很大程度上受到加性遗传（63%）和共同环境（37%）的影响，尽管这一潜在变量在母亲报告（66%）中比在青少年报告（9%）中造成的差异要大得多。此外，仅在青少年报告中发现了特定于线人的附加遗传和共同环境影响，而母亲报告中所有剩余的差异都归因于非共同环境影响。在衡量关系攻击性和多个线人的重要性的背景下讨论了结果。
Although the study of relational aggression is gaining attention in the literature, little is known about the underlying causes of this behavior and the relative validity of various informants. These issues were addressed in a sample of 1,981 6-to 18-year-old twin pairs (36% female, 34% male, 30% opposite-sex). Relational aggression was assessed via maternal and self-report using a structured interview. Univariate models estimated genetic and environmental influences by informant and examined evidence for gender differences. A psychometric model combined data from both informants to estimate etiologic influences that were both common to the informants and informant specific. In both sexes, the latent variable reflecting the mother’s and child’s shared perception of the child’s relational aggression was substantially influenced by both additive genetic (63%) and shared environmental (37%) influences, although this latent variable accounted for much greater variance in the maternal report (66%) than it did in the youth report (9%). In addition, informant-specific additive genetic and shared environmental influences were found only for the youth report, with all remaining variance in the mother’s report attributed to nonshared environmental influences. Results are discussed in the context of measuring relational aggression and the importance of multiple informants.
