依恋理论和研究的一个长期问题是，儿童的遗传特征是否会影响依恋安全性的发展及其随时间的稳定性。本研究试图复制和扩展最近的研究结果表明，发展稳定性的附件安全性是由催产素受体（OXTR）的遗传变异。使用来自550多个个体的纵向数据，没有证据表明OXTR rs53576在18岁的成人依恋访谈期间调节了幼儿期依恋安全性与整体心理一致性（“安全性”）之间的关联。涉及第二种常见研究的OXTR变体（rs2254298）和个体的忽视和专注依恋心理状态指数的其他分析也未能提供强有力的证据，证明催产素调节了整个发展过程中依恋安全性的稳定性。讨论的重点是研究策略，调查整个生命周期的依恋安全的遗传贡献。
A longstanding question for attachment theory and research is whether genetically based characteristics of the child influence the development of attachment security and its stability over time. This study attempted to replicate and extend recent findings indicating that the developmental stability of attachment security is moderated by oxytocin receptor (OXTR) genetic variants. Using longitudinal data from over 550 individuals, there was no evidence that OXTR rs53576 moderated the association between attachment security during early childhood and overall coherence of mind (“security”) during the Adult Attachment Interview at age 18 years. Additional analyses involving a second commonly investigated OXTR variant (rs2254298) and indices of individuals’ dismissing and preoccupied attachment states of mind also failed to provide robust evidence for oxytonergic moderation of the stability in attachment security across development. The discussion focuses on research strategies for investigating genetic contributions to attachment security across the life span.
