先前的研究表明，外向性和神经质很大程度上受到基因型和环境的影响。这项研究评估了遗传和环境对五因素人格模型的其他三个组成部分的影响：体验开放性、宜人性和尽责性。对 82 对同卵双胞胎和 171 对分开抚养的异卵双胞胎以及 132 对同卵双胞胎和 167 对一起抚养的异卵双胞胎进行了简化版的 NEO 人格量表 (NEO-PI)。对开放性和尽责性的遗传和环境影响的估计与其他人格研究中发现的相似：遗传影响很大，并且几乎没有证据表明共同的养育环境。宜人性的结果有所不同：遗传影响仅占方差的 12%，共同的养育环境占方差的 21%。在模型拟合分析中几乎没有发现遗传和环境参数存在显着的性别或年龄差异。
Previous research has indicated that extraversion and neuroticism are substantially affected both by genotype and environment. This study assesses genetic and environmental influences on the other three components of the five-factor model of personality: Openness to Experience, Agreeableness, and Conscientiousness. An abbreviated version of the NEO Personality Inventory (NEO-PI) was administered to 82 pairs of identical twins and 171 pairs of fraternal twins reared apart and 132 pairs of identical twins and 167 pairs of fraternal twins reared together. Estimates of genetic and environmental effects for Openness and Conscientiousness were similar to those found in other studies of personality: Genetic influence was substantial and there was little evidence of shared rearing environment. Results for Agreeableness were different: Genetic influence accounted for only 12% of the variance and shared rearing environment accounted for 21% of the variance. Few significant gender or age differences for genetic and environmental parameters were found in model-fitting analyses.
