The genetic and environmental sources of variance in mothers' and fathers' ratings of child temperament in middle childhood were estimated and compared. Parents of 88 MZ twin pairs and 109 same-sex DZ twin pairs completed a temperament questionnaire. For Effortful Control, significant genetic and environmental effects were indicated across mothers' and fathers' ratings, but parent differences were found for the Negative Affectivity factor. When present, sibling contrast effects were not consistent for mothers and fathers. Parental ratings of the Effortful Control factor were best explained by the Biometric model whereas the Negative Affectivity factor was best explained by the Rater Bias model. Overall, mothers' and fathers' ratings yielded similar evidence of genetic and environmental etiology of temperament in middle childhood.
对儿童中期母亲和父亲对孩子气质评分的遗传和环境变异来源进行了估计和比较。88对同卵双胞胎和109对同性异卵双胞胎的父母完成了一份气质问卷。对于努力控制,母亲和父亲的评分都显示出显著的遗传和环境影响,但在消极情感因素上发现了父母差异。当存在时,兄弟姐妹的对比效应在母亲和父亲之间并不一致。努力控制因素的父母评分最好用生物测量模型来解释,而消极情感因素最好用评分者偏差模型来解释。总体而言,母亲和父亲的评分在儿童中期气质的遗传和环境病因方面产生了相似的证据。
