本研究探讨了人格和气质特征的遗传力估计的准确性的线人评估的修改作用。以7199名被试的1118对双生子为研究对象，分析了双生子对同伴评价的相关性，并将其作为评价同伴评价信息准确性的指标。此外，估计的遗传效应和信息准确性之间的相互作用进行了测试，自我报告的特定方差不占同行报告。遗传力估计的基础上的双胞胎同伴报告之间的相关性增加的程度同伴报告的准确性，而它减少了自我报告的残差，由于增加的遗传重叠之间的自我和同伴报告的信息的准确性程度。这表明：（1）当对了解目标的被试的报告进行建模时，气质和人格特质的遗传度估计值更大;（2）人格特质自我报告中的遗传方差确实反映了准确的特质方差，而不是自我评价者偏差中的遗传方差。
This study examined the modifying role of accuracy of informant assessments for heritability estimates of personality and temperamental traits. Data from 7199 individuals including data of 1118 twin pairs were analyzed to estimate heritability on the basis of twin correlations of peer assessments for different levels of familiarity between peers and target twins treated as an index of information accuracy of peer assessments. Moreover, interactions between estimates of genetic effects and information accuracy were tested for self-report-specific variance not accounted for by peer reports. Heritability estimates on the basis of correlations between peer reports on twins increased with the degree of peer reports’ accuracy, whereas it decreased for self-report residuals due to an increase of the genetic overlap between self- and peer-reports with the degree of information accuracy. This indicates (1) that estimates of heritability of temperamental and personality traits are larger when modeling reports of informants who know the targets well and (2) that genetic variance in self-reports on personality traits indeed reflects accurate trait variance rather than genetic variance in self-rater biases.
