Why is parenting in adolescence predictive of maladaptive personality in adulthood? This study sets out to investigate environmental and genetic factors underlying the association between parenting and maladaptive personality longitudinally in a large sample of twins. The present study addressed this question via a longitudinal study focused on two cohorts of twins assessed on aspects of perceived parenting (parent- and adolescent-reported) at age 14 years ( =1,094 pairs). Participants were followed to adulthood, and maladaptive personality traits were self-reported using the Personality Inventory for DSM-5 (PID-5) at age 24 or 34 years. We then modeled these data using a bivariate biometric model, decomposing parenting-maladaptive personality associations into additive genetic, shared environmental, and nonshared environmental factors. Numerous domains of adolescent-reported parenting predicted adult maladaptive personality. Further, we found evidence for substantial additive genetic ( ranging from 0.22 to 0.55) and (to a lesser extent) nonshared environmental factors ( ranging from 0.10 to 0.15) that accounted for the association between perceived parenting reported in adolescence and adult personality. Perceived parenting in adolescence and maladaptive personality in adulthood may be related due to some of the same genetic factors contributing to both phenotypes at different developmental periods.
为什么青春期的养育方式能预测成年后的适应不良型人格？本研究旨在通过对大量双胞胎样本进行纵向研究，探究养育方式与适应不良型人格之间关联背后的环境和遗传因素。本研究通过一项纵向研究解决了这个问题，该研究聚焦于两组双胞胎队列，在14岁时对他们在感知到的养育方式（父母报告和青少年报告）方面进行评估（n = 1,094对）。参与者被追踪至成年期，并在24岁或34岁时使用《精神疾病诊断与统计手册》第5版人格量表（PID-5）进行适应不良型人格特质的自我报告。然后，我们使用双变量生物统计学模型对这些数据进行建模，将养育方式与适应不良型人格的关联分解为加性遗传、共享环境和非共享环境因素。青少年报告的养育方式的多个领域预测了成年后的适应不良型人格。此外，我们发现有证据表明存在大量的加性遗传因素（范围从0.22到0.55）以及（在较小程度上）非共享环境因素（范围从0.10到0.15），这些因素解释了青少年报告的感知养育方式与成年人格之间的关联。青春期的感知养育方式和成年期的适应不良型人格可能由于一些在不同发育阶段对两种表型都有影响的相同遗传因素而相关。
