本文探讨了社会控制和社会风险机制和多巴胺能系统(DAT 1和DRD 2)内的基因之间的相互作用,与青少年和年轻人的严重和暴力形式的犯罪行为。我们使用来自全国青年调查家庭研究的九波数据,在基因-环境相互作用框架内,在四个社会层面(包括学校、邻里、朋友和家庭)研究保护性或风险性社会因素的相关性。我们扩展了以前在这方面的工作,提供了一个可测试的类型学的基因-环境相互作用,从目前的理论在这一领域。我们发现了一致的证据表明,pupper-risky基因型和犯罪行为之间的关联被抑制在保护性的社会环境。我们还提供了一些证据,支持这些结果的差异易感性假说。我们的研究结果在很大程度上证实了先前工作的结论,并继续强调社会环境在复杂行为的候选基因研究中的关键作用。
This paper examines the interaction between social control and social risk mechanisms and genes within the dopaminergic system (DAT1 and DRD2) as related to serious and violent forms of delinquent behavior among adolescents and young adults. We use nine waves of data from the National Youth Survey Family Study to examine the relevance of protective or risky social factors at four social levels including school, neighborhood, friends, and family within the gene-environment interaction framework. We extend previous work in this area by providing a testable typology of gene-environment interactions derived from current theories in this area. We find consistent evidence that the associations between putatively risky genotypes and delinquent behavior are suppressed within protective social environments. We also provide some evidence that supports the differential susceptibility hypothesis for these outcomes. Our findings largely confirm the conclusions of previous work and continue to highlight the critical role of the social environment within candidate gene studies of complex behaviors.
