这项纵向同卵双胞胎差异研究探索了出生体重和早期家庭环境以及教师评定的行为问题和7岁时的学习成绩之间的关系。MZ在焦虑、多动症、品行问题、同伴问题和学业成就方面的差异与MZ在出生体重和早期家庭环境方面的差异显著相关，显示出高达2%的效应大小。正如早期研究预测的那样，在不协调的极端情况下，关联性增加，即使在纵向的交叉评分者设计中，影响大小高达12%。与之前的研究一样，这些非共享环境(NSE)关系中的一些似乎在一定程度上是由于SES、家庭混乱和母亲抑郁的作用。高危家庭通常表现出更强的负面关联。
This longitudinal monozygotic (MZ) twin differences study explored associations between birthweight and early family environment and teacher-rated behaviour problems and academic achievement at age 7. MZ differences in anxiety, hyperactivity, conduct problems, peer problems and academic achievement correlated significantly with MZ differences in birthweight and early family environment, showing effect sizes of up to 2%. As predicted by earlier research, associations increased at the extremes of discordance, even in a longitudinal, cross-rater design, with effect sizes reaching as high as 12%. As with previous research some of these nonshared environmental (NSE) relationships appeared to operate partly as a function of SES, family chaos and maternal depression. Higher-risk families generally showed stronger negative associations.
