父亲的参与对儿童的发展成果有独特的贡献。然而，来自农村地区的未婚非裔美国父亲参与父亲的前因在很大程度上被忽视了。本研究测试了一个概念模型，该模型将童年创伤和成年早期社会不稳定的回顾性报告与生活在美国东南部资源贫乏的农村社区的未婚非洲裔美国男性的父亲参与联系起来。我们假设这些因素会通过催产素受体基因（OXTR）的DNA甲基化间接影响父亲的参与。192名父亲在成年早期参与了三波数据收集。父亲在第1波报告了社会不稳定性，在第2波通过唾液样本评估了OXTR甲基化，在第3波收集了父亲参与、回顾性童年创伤和父亲与子女母亲关系质量的测量结果。结构方程模型表明，童年创伤直接关系到父亲参与水平的降低和社会不稳定性的增加。社会不稳定与OXTR甲基化水平升高有关，这反过来又预示着父亲参与的减少。社会不稳定性通过OXTR甲基化对父亲参与的间接影响是显着的。这些协会没有通过父亲与孩子的母亲的关系，并仍然显着，甚至占之间的关联，父母间的关系质量和父亲的参与。研究结果表明，OXTR甲基化可能是一种生物学机制，将社会不稳定与未婚非裔美国人父亲在弱势环境中的父亲参与联系起来，并强调了童年创伤对父亲参与的不利影响。
Father involvement contributes uniquely to children’s developmental outcomes. The antecedents of father involvement among unmarried, African American fathers from rural areas, however, have been largely overlooked. The present study tested a conceptual model linking retrospective reports of childhood trauma and early adulthood social instability to father involvement among unmarried, African American men living in resource-poor, rural communities in the southeastern United States. We hypothesized these factors would influence father involvement indirectly, via DNA methylation of the oxytocin receptor gene (OXTR). A sample of 192 fathers participated in three waves of data collection in early adulthood. Fathers reported on social instability at Wave 1, OXTR methylation was assessed via saliva samples at Wave 2, and measures of father involvement, retrospective childhood trauma, and quality of the fathers’ relationships with their children’s mothers were collected at Wave 3. Structural equation modeling indicated that childhood trauma was related directly to reduced levels of father involvement and to increased social instability. Social instability was associated with elevated levels of OXTR methylation, which in turn predicted decreased father involvement. The indirect effect from social instability to father involvement via OXTR methylation was significant. These associations did not operate through fathers’ relationship with the child’s mother, and remained significant even accounting for associations between inter-parental relationship quality and father involvement. Findings suggest that OXTR methylation may be a biological mechanism linking social instability to father involvement among unmarried, African American fathers in vulnerable contexts and underscore the detrimental influence of childhood trauma on father involvement.
