本研究旨在探讨人格特质与回顾性家庭环境的关系。从耶拿双胞胎社会态度研究中获得了226对同卵双胞胎和168对异卵双胞胎的数据。人格特质的测量使用自我和同行报告版本的德国NEO人格量表修订版。德国版本的块环境问卷被用来衡量两个广泛的方面的家庭环境回顾性的支持和组织。我们可以复制早期的研究结果，这些家庭环境方面的回顾性报告部分遗传影响。支持和组织的遗传方差分别有66%和24%可以由自评人格的遗传方差来解释。这一点通过使用个性的同伴报告得到了重复，41%的人解释了支持的遗传变异，17%的人解释了组织的遗传变异。环境因素的影响微不足道。这表明，性格和回顾性回忆的家庭环境之间的关系在很大程度上是遗传介导的。
In this study we analyzed the etiology of the relationship between personality traits and retrospectively recalled family environment. The data of 226 identical and 168 fraternal twin pairs reared together from the Jena twin study of social attitudes were available. Personality traits were measured using the self- and peer report versions of the German NEO-personality inventory-revised. A German version of Blocks Environmental Questionnaire was applied to measure two broad dimensions of the family environment retrospectively: support and organization. We could replicate earlier findings that retrospective reports of these family environment dimensions were in part genetically influenced. A total of 66% of the genetic variance in support and 24% in organization could be accounted for by heritable variance in self-rated personality. That was replicated by using peer reports of personality, 41% explained genetic variance in support and 17% in organization. Environmental mediations were negligible. This indicates that the relationship between personality and retrospectively recalled family environment is largely genetically mediated.
