精神病倾向和自闭症特征之间存在一些行为重叠，这两种表型都被认为与共情问题有关。然而，与这两种情况相关的广泛的行为特征和认知情感缺陷至少部分是可分离的。这项研究的主要目的是评估精神病倾向的病因学在多大程度上独立于自闭症特征。第二个目的是研究情绪归因能力的病因学及其与精神病倾向和自闭症特征的关系。基于642对双胞胎的样本数据，与精神病倾向相关的遗传和非共享环境影响在很大程度上是每个表型所独有的。精神病倾向和自闭症特征之间的共同环境影响重叠。抑郁情绪归因能力与精神病倾向和自闭症特征的增加有关，这些关联主要由共同的遗传因素解释。
Some behavioural overlap exists between psychopathic tendencies and autistic traits, and both phenotypes are thought to be associated with problems in empathy. However, the broad behavioural profiles and the cognitive-affective deficits associated with the two conditions are at least partly separable. The main aim of this study was to assess the extent to which the aetiology of psychopathic tendencies is independent of autistic traits. A secondary aim was to study the aetiology of emotion attribution ability and its association with psychopathic tendencies and autistic traits. Based on data from a sample of 642 twin pairs, the genetic and nonshared environmental influences related to psychopathic tendencies were largely unique to each phenotype. Common environmental influences between psychopathic tendencies and autistic traits overlapped. Poorer emotion attribution ability was associated with increased psychopathic tendencies and autistic traits, and these associations were mainly explained by common genetic factors.
