The Child Behavior Checklist (CBCL) was completed by parents of 181 pairs of same-sex twins ages 7-15 (mean age = 11.0 years). Correlations between scores on the CBCL scales for 99 pairs of monozygotic twins and 82 pairs of dizygotic twins indicated significant genetic influences that varied according to the specific area of competence and problem behavior. Model-fitting estimates derived from multiple regression analyses indicated significant genetic influence on competence in school and on all areas of problem behavior. In addition, significant shared environmental influence was detected for amount and quality of participation in activities, quality of social relationships, performance in school, anxiety/depression, and delinquent behaviour. Implications for future work on the mechanisms underlying these effects are discussed.
181对年龄在7至15岁（平均年龄 = 11.0岁）的同性双胞胎的父母完成了儿童行为检查表（CBCL）。99对同卵双胞胎和82对异卵双胞胎在CBCL量表上的得分之间的相关性表明，存在显著的遗传影响，且这种影响因能力和问题行为的具体领域而异。多元回归分析得出的模型拟合估计表明，遗传因素对学业能力和所有问题行为领域都有显著影响。此外，在活动参与的数量和质量、社会关系质量、学业表现、焦虑/抑郁以及违法行为方面，检测到显著的共享环境影响。文中还讨论了这些影响背后机制的未来研究工作的意义。
