收养研究提供了一个机会，以检查双胞胎研究的推论，遗传和环境对人格的影响。德克萨斯州收养项目从300个收养家庭的成员那里获得了性格测试和评级：成年人的MMPI和16 PF，儿童的卡特尔量表和父母评级。总的来说，家庭成员之间的性格相似性很小，无论是生物学上还是收养关系。中位相关性通常为正，但低于0.10。消除评级偏差和使用多重相关性并没有产生显着更高的预测水平，但限制到一个子样本的测量良好的儿童提供了更高的相关性和更多的遗传性的证据，特别是在外向性领域。
Adoption studies provide an opportunity to check on twin-study inferences about genetic and environmental effects on personality. The Texas Adoption Project obtained personality tests and ratings from members of 300 adoptive families: MMPIs and 16PFs for adults, and Cattell scales and parents' ratings for children. Overall there was little personality resemblance among family members, either biologically or adoptively related. Median correlations were typically positive, but under 0.10. Elimination of a rating bias and the use of multiple correlations did not yield notably higher levels of prediction, but restriction to a subsample of well-measured children provided higher correlations and more evidence of heritability, particularly in the extraversion domain.
