Abstract

In the current study, common and unique genetic and environmental influences on personality and a broad range of well-being measures were investigated. Data on the Big Five, life satisfaction, quality of life, self-rated health, loneliness, and depression from 14,253 twins and their siblings (age M: 31.82, SD: 14.41, range 16–97) from the Netherlands Twin Register were used in multivariate extended twin models. The best-fitting theoretical model indicated that genetic variance in personality and well-being traits can be decomposed into effects due to one general, common factor ( Mdn: 60%, range 15%–89%), due to personality-specific ( Mdn: 2%, range 0%–78%) and well-being-specific ( Mdn: 12%, range 4%–35%) factors, and trait-specific effects ( Mdn: 18%, range 0%–65%). Significant amounts of non-additive genetic influences on the traits’ (co)variances were found, while no evidence was found for quantitative or qualitative sex differences. Taken together, our study paints a fine-grained, complex picture of common and unique genetic and environmental effects on personality and well-being. Implications for the interpretation of shared variance, inflated phenotypic correlations between traits and future gene finding studies are discussed.

从基因信息化设计中解读人格与幸福的关系

在目前的研究中，研究了常见和独特的遗传和环境对个性的影响以及广泛的幸福感测量。来自荷兰双胞胎登记处的14253对双胞胎及其兄弟姐妹（年龄M:31.82，SD:14.41，范围16-97）的五大数据、生活满意度、生活质量、自评健康、孤独和抑郁被用于多变量扩展双胞胎模型。最佳拟合理论模型表明，个性和幸福感特征的遗传变异可以分解为一个一般的共同因素（Mdn:60%，范围15%-89%）、个性特异性因素（Mdn：2%，范围0%-78%）和幸福感特异性因素的影响（Mdn:12%，范围4%-35%），以及特异性效应（Mdn:18%，范围0%-65%）。发现了大量的非加性遗传对性状（共）方差的影响，而没有发现数量或质量性别差异的证据。总之，我们的研究描绘了一幅精细而复杂的画面，描绘了常见和独特的遗传和环境对个性和幸福感的影响。讨论了共享方差的解释、性状之间膨胀的表型相关性和未来基因发现研究的意义。

期刊介绍： It is intended that the journal reflects all areas of current personality psychology. The Journal emphasizes (1) human individuality as manifested in cognitive processes, emotional and motivational functioning, and their physiological and genetic underpinnings, and personal ways of interacting with the environment, (2) individual differences in personality structure and dynamics, (3) studies of intelligence and interindividual differences in cognitive functioning, and (4) development of personality differences as revealed by cross-sectional and longitudinal studies.
