采用483对双胞胎志愿者(236对同卵和247对)的数据，研究了遗传和非遗传对人格问题维度评估(DAPP-DQ)量表测量的人格障碍特征等级的遗传和非遗传影响。DAPP-DQ测评人格障碍的4个高阶因子、18个基本维度和69个方面特征。同卵双生子和异卵双生子的相关系数分别为0.26~0.56和0.03~0.41。广义遗传力估计范围从0到58%(中值为45%)。加性遗传效应和独特的环境效应是影响这些尺度的主要因素，其中独特的环境影响在所有等级的大多数性状的方差中所占比例最大。
Genetic and non-genetic influences on the hierarchy of traits that delineate personality disorder as measured by the Dimensional Assessment of Personality Problems (DAPP-DQ) scale were examined using data from a sample of 483 volunteer twin pairs (236 monozygotic pairs and 247 dizygotic pairs). The DAPP-DQ assesses four higher-order factors, 18 basic dimensions and 69 facet traits of personality disorder. The correlation coefficients for monozygotic and dizygotic twin pairs ranged from 0.26 to 0.56 and from 0.03 to 0.41, respectively. Broad heritability estimates ranged from 0 to 58% (median value, 45%). Additive genetic effects and unique environmental effects emerged as the primary influences on these scales, with unique environmental influences accounting for the largest proportion of the variance for most traits at all levels of the hierarchy.
