虽然人们普遍认为青少年自我能力感知的来源在于共同的家庭环境影响，但尚未探索非共同环境或遗传影响的贡献。我们对720对10至18岁的青少年进行了兄弟姐妹相似性调查，采用双胞胎、全兄妹和同父异母兄妹设计。我们的目标是评估共享和非共享环境影响的程度，并将由于共享遗传遗传而产生的相似性与由于共享环境经验而产生的相似性区分开来。共享环境在任何尺度上都不显著。在学业、社会、身体和运动能力这四个分量表中，有显著的遗传影响。我们还探讨了基因对感知能力影响的可能来源。双变量模型揭示了学业能力与词汇量、社会能力与社交能力之间共同的遗传变异。然而，这些措施并不能解释感知到的社会和学术能力的所有遗传差异。
Although it is generally assumed that the origins of adolescents' perceptions of self‐competence lie in shared family environmental influences, the contributions of nonshared environmental or genetic influences have not been explored. We investigated sibling resemblance for perceived competence and self‐worth in 720 adolescent pairs aged 10 to 18 years, using a twin, full sibling, and step‐sibling design. Our goals were to assess the magnitude of shared and nonshared environmental influences and to disentangle resemblance due to shared genetic heritage from that due to shared environmental experiences. Shared environment was not significant for any of the scales. 4 of the subscales showed significant genetic influence: scholastic, social, physical, and athletic competence. We also explored possible sources of genetic influences on perceived competence. Bivariate models revealed common genetic variance between scholastic competence and vocabulary and social competence and sociability. These measures, however, did not account for all of the genetic variance in perceived social and scholastic competence.
