我们进行了一项生物特征研究，在17岁至24岁的男性和女性双胞胎社区样本中检查人格的稳定性和变化。使用Tellegen的多维人格问卷（MPQ），方面的负非理性（NEM）大幅下降，在平均值和个人水平，而方面的约束（CON）随着时间的推移而增加。此外，在青春期后期，NEM最低，CON最高的个体随着时间的推移保持最稳定，而那些表现出相反的轮廓（较高的NEM，较低的CON）的变化最大的方向朝着生长和成熟。性别差异的分析产生了更大的平均水平增加，随着时间的推移，女性相比，男性的CON和更大的平均水平增加，男性比女性的方面的积极主动性（PEM）。生物统计学分析表明，人格的等级稳定性在很大程度上是遗传的，等级变化由非共享环境（和错误）以及基因介导。研究结果与先前的证据相一致，即在成年期出现的人格成长和成熟的规范趋势。
We conducted a longitudinal-biometric study examining stability and change in personality from ages 17 to 24 in a community sample of male and female twins. Using Tellegen's (in press) Multidimensional Personality Questionnaire (MPQ), facets of Negative Emotionality (NEM) declined substantially at the mean and individual levels, whereas facets of Constraint (CON) increased over time. Furthermore, individuals in late adolescence who were lowest on NEM and highest on CON remained the most stable over time, whereas those exhibiting the inverse profile (higher NEM, lower CON) changed the most in a direction towards growth and maturity. Analyses of gender differences yielded greater mean-level increases over time for women as compared to men on facets of CON and greater mean-level increases for men than women on facets of Agentic Positive Emotionality (PEM). Biometric analyses revealed rank-order stability in personality to be largely genetic, with rank-order change mediated by both the nonshared environment (and error) as well as genes. Findings correspond with prior evidence of a normative trend toward growth and maturity in personality during emerging adulthood.
