Genetic and environmental influences on problem behaviors were studied in 3-year-old twins. Fathers' and mothers' ratings of problem behaviors in twins-236 monozygotic (MZ) girls, 210 MZ boys, 238 dizygotic (DZ) girls, 265 DZ boys, and 409 DZ opposite sex pairs- were obtained with the Child Behavior Checklist for Ages 2-3 (T.M. Achenbach, 1992). Twin correlations and results from a model fitting approach showed that genetic, shared environmental, and nonshared environmental influences accounted on average for about 64%, 9%, and 27% of the variance. Although shared environmental influences were small for most scales, they were important for Total Problems and somewhat larger for Externalizing than for Internalizing behaviors. Significant sex differences in genetic and environmental influences and evidence for sibling contrast effects were found for the Overactive scale.
对3岁双胞胎的问题行为的遗传和环境影响进行了研究。通过使用《2 - 3岁儿童行为检查表》（T.M. 阿肯巴克，1992年），获得了双胞胎（236对同卵（MZ）女孩、210对MZ男孩、238对异卵（DZ）女孩、265对DZ男孩以及409对DZ异性双胞胎）父母对其问题行为的评分。双胞胎相关性以及模型拟合方法的结果表明，遗传、共享环境和非共享环境影响平均分别占方差的约64%、9%和27%。尽管对于大多数量表而言，共享环境影响较小，但它们对总问题很重要，并且外化行为方面的影响比对内化行为的影响稍大。在多动量表上发现了遗传和环境影响方面显著的性别差异以及兄弟姐妹对比效应的证据。
