养育行为的个体差异部分归因于遗传因素。在本研究中，作者试图确定遗传影响的程度是否根据所考虑的父母行为类型而变化。基于人口的 2,334 对芬兰双胞胎样本对他们的父亲和母亲在童年时期表现出的身体感情、控制、虐待和冷漠进行了评级。遗传影响、共同环境影响和非共同环境影响分别占每个养育措施方差的小到中等比例（17%-30%）、小到大比例（22%-44%）和中到大比例（37%-55%）。母亲和父亲或四种父母行为的效应大小没有显着差异。遗传结果可能反映父母对受遗传影响的个体行为（基因-环境相关性）或个体对这种关系的看法（基因-人相关过程）做出反应的特征风格。这些发现对于家庭的干预和预防工作以及解释基因与养育行为之间相互作用的证据具有重要意义。
Individual differences in parenting behaviors are due, in part, to genetic factors. In the present study, the authors sought to determine whether the degree of genetic influence varied according to the type of parental behavior under consideration. A population-based sample of 2,334 pairs of Finnish twins provided ratings on the physical affection, control, abusiveness, and indifference shown by their father and mother during childhood. Genetic influences, shared environmental influences, and nonshared environmental influences accounted for a small-to-medium proportion (17%-30%), a small-to-large proportion (22%-44%), and a medium-to-large proportion (37%-55%) of the variance in each parenting measure, respectively. There were no significant differences in effect sizes for mothers and fathers or across the 4 types of parental behavior. The genetic results may reflect characteristic styles with which parents respond to genetically influenced behaviors of individuals (gene- environment correlations) or individual perceptions of this relationship (gene-person correlation processes). The findings have implications for intervention and prevention work with families and for interpretation of evidence for interactions between genes and parenting behaviors.
