本研究的目的是评估假设，双胞胎的关系是附件，使用全国代表性样本的数据。结果表明，双胞胎兄弟姐妹比非双胞胎兄弟姐妹更容易依恋他们的兄弟姐妹。此外，分析表明，这两个依恋理论和包容健身的角度是必要的解释这些发现。也就是说，双胞胎比非双胞胎兄弟姐妹更容易被依恋，正如从依恋的角度所预期的那样。但是，同卵双胞胎比异卵双胞胎更有可能相互依恋，这从包容性健康的角度来看是可以预期的。横断面分析表明，老年人比年轻人更不可能使用他们的兄弟姐妹作为一个附件数字相比，年轻人，已婚成年人更不可能使用他们的兄弟姐妹作为一个附件数字比未婚的人。
The objective of this research was to evaluate the hypothesis that twin relationships are attachments, using data from a nationally representative sample. The results indicated that twin siblings were more likely than nontwin siblings to be attached to their siblings. Moreover, analyses indicated that both attachment theoretical and inclusive fitness perspectives are necessary for explaining these findings. Namely, twins were more likely to be attached than nontwin siblings, as expected from an attachment perspective. But identical twins were more likely than fraternal twins to be attached to one another, as might be expected from an inclusive fitness perspective. Cross-sectional analyses indicated that older people are less likely than younger people to use their sibling as an attachment figure compared to younger people and that married adults are less likely to use their sibling as an attachment figure than nonmarried people.
