Oxytocin has been shown to be important for social behavior and emotional attachments in early life and may also mediate effects of early experiences on social motivation in adulthood. In animal models, early maternal separation results in alterations in the oxytocin system, with effects on sexual, maternal, and stress reactivity behaviors in adulthood. Studies of children experiencing parental divorce find effects on mood disorders, substance abuse, and other behaviors in adulthood. Here, we examine the effect of divorce on adult urine oxytocin levels. To stimulate oxytocin release, participants, aged 18 to 62, were asked to complete a set of questionnaires on attachment style, parental history of divorce (age at parental divorce ranged from 0 to 20), and other measures. A sample of urine was then collected for the oxytocin assay. Urine oxytocin concentrations were substantially lower (p = .016) in subjects who experienced parental divorce (M = 3.70, Standard Error of the Mean = 0.73), compared to those who did not (M = 8.00, Standard Error of the Mean = 1.21), and correlated with responses on several attachment instruments. These results suggest that oxytocin levels are adversely affected by parental divorce in humans and may be related to attachment measures in adulthood.

儿童时期的父母离婚与成年期尿中催产素浓度降低有关。

催产素已被证明对早期生活中的社交行为和情感依恋很重要，并且还可能介导早期经历对成年期社会动机的影响。在动物模型中，早期的母体分离会导致催产素系统发生变化，从而影响成年期的性，母体和应激反应行为。对经历过父母离婚的孩子的研究发现，它们对情绪障碍，药物滥用和成年后的其他行为有影响。在这里，我们检查了离婚对成人尿中催产素水平的影响。为了刺激催产素的释放，要求年龄在18至62岁之间的参与者填写一套有关依恋类型，父母离婚史（父母离婚年龄为0至20岁）和其他措施的问卷。然后收集尿液样本进行催产素测定。经历过父母离婚的受试者（M = 3.70，平均值的标准误差= 0.73）的尿中催产素浓度明显低于未经历父母离婚的受试者（M = 8.00，平均值的标准误差= 1.21）（p = .016） ），并与几种附件工具的响应相关。这些结果表明催产素水平受到人类父母离婚的不利影响，并且可能与成年期的依恋措施有关。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。这些结果表明催产素水平受到人类父母离婚的不利影响，并且可能与成年期的依恋措施有关。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。这些结果表明催产素水平受到人类父母离婚的不利影响，并且可能与成年期的依恋措施有关。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
