来自明尼苏达州成人发展和衰老双胞胎研究的833对双胞胎样本完成了两次多维人格问卷（MPQ; Tellegen, 1982），第一次测试的平均年龄为59.4 （sd=9.7）岁，第二次测试的平均年龄为64.4 （sd=10.2）岁（平均复测间隔5.0年，sd=2.36，范围1.0-10.4年）。从第一次到第二次测试，量表得分的均值和标准差都非常稳定。此外，样本参与者倾向于保留他们在量表上的等级顺序（各量表的平均r= 0.76）。双变量生物计量分析表明，基因对大多数量表得分的影响在两个波范围内几乎是完全相关的。95 - 1.00)。非共享的环境影响也在两个波（范围）之间高度相关。53到0.73)。在两个时间点指定相同方差成分并将遗传相关性固定为1.00的模型提供了更好的拟合。结果表明，成年后期人格的高度稳定性有很强的遗传基础，并辅以环境影响的稳定性。
A sample of 833 twins from the Minnesota Twin Study of Adult Development and Aging completed the Multidimensional Personality Questionnaire (MPQ; Tellegen, 1982) twice, averaging 59.4 (sd=9.7) years of age at first and 64.4 (sd=10.2) years of age at second testing (average retest interval 5.0 years, sd=2.36, range 1.0-10.4 years). Both means and standard deviations of scale scores were extremely stable from first to second testing. In addition, sample participants tended to retain their rank order on the scales (average r=.76 across scales). Bivariate biometric analyses showed that the genetic influences on most of the scale scores were almost perfectly correlated across the two waves (range .95 to 1.00). The nonshared environmental influences were also highly correlated across the two waves (range .53 to .73). Models specifying identical variance components at the two time points and fixing the genetic correlation to 1.00 provided improved fit. The results suggest that the high stability of personality in later adulthood has a strong genetic foundation, supplemented by stability of environmental effects.
