精神病态的特征包括人际操纵、冷酷无情、不稳定的生活方式和反社会行为。虽然成人精神病特征来自遗传和环境风险，但没有研究研究探讨成人精神病特征与儿童时期养育经历之间的病因学关联，或者使用遗传信息设计的养育实践可能影响成人精神病特征遗传性的程度。总共有1842名来自社区的成年双胞胎报告了他们目前的精神病特征和童年时期的消极育儿经历。我们拟合双变量遗传模型的数据，分解的方差内，和协方差之间，精神病特征和感知到的消极养育到他们的遗传和环境成分。然后，我们拟合了一个基因型×环境相互作用模型，以评估是否消极的父母调节精神病特征的病因。精神病特征是中度遗传与大量的非共享的环境影响。有显着的相关性之间的感知消极养育和四个精神病方面（人际操纵，不稳定的生活方式，反社会倾向，但不是无情的影响）。这些关联归因于共同的非共享环境途径，而不是重叠的遗传效应。此外，我们发现，主要是共享的环境影响更强的心理变态特征的个人与历史上更大的负面养育。利用遗传信息设计，我们发现遗传和非共享环境因素都会导致精神病特征的出现。此外，消极的父母的看法出现了一个明确的环境影响的发展，人际关系，生活方式和反社会功能的精神病。
Psychopathic traits involve interpersonal manipulation, callous affect, erratic lifestyle, and antisocial behavior. Though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design. In total, 1842 adult twins from the community reported their current psychopathic traits and experiences of negative parenting during childhood. We fit bivariate genetic models to the data, decomposing the variance within, and the covariance between, psychopathic traits and perceived negative parenting into their genetic and environmental components. We then fit a genotype × environment interaction model to evaluate whether negative parenting moderated the etiology of psychopathic traits. Psychopathic traits were moderately heritable with substantial non-shared environmental influences. There were significant associations between perceived negative parenting and three of four psychopathy facets (interpersonal manipulation, erratic lifestyle, antisocial tendencies, but not callous affect). These associations were attributable to a common non-shared environmental pathway and not to overlapping genetic effects. Additionally, we found that primarily shared environmental influences were stronger on psychopathic traits for individuals with a history of greater negative parenting. Utilizing a genetically-informed design, we found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits. Moreover, perceptions of negative parenting emerged as a clear environmental influence on the development of interpersonal, lifestyle, and antisocial features of psychopathy.
