研究人员通常会分析双胞胎样本，以便将性状差异分解为遗传和环境因素。这种方法技术被称为基于双胞胎的研究，它建立在几个假设的基础上，为了产生公正的结果，必须满足这些假设。虽然研究已经分析了某些假设的可行性，如平等的环境，但很少有人关注从双胞胎样本中收集的结果是否可以推广到更广泛的非双胞胎人群。目前的研究分析了来自全国青少年健康纵向研究的数据，结果表明双胞胎在许多行为和发展方面与非双胞胎的普通人群没有系统的不同。此外，特定协变量对反社会行为测量的影响似乎没有因双胞胎状态而异。总之，从基于双胞胎的研究中收集到的关于反社会行为的病因的证据（例如，遗传力估计）很可能推广到非双胞胎人群。
Researchers typically analyze samples of twin pairs in order to decompose trait variance into genetic and environmental components. This methodological technique, referred to as twin-based research, rests on several assumptions that must be satisfied in order to produce unbiased results. While research has analyzed the tenability of certain assumptions such as equal environments, less attention has been given to whether results gleaned from samples of twins generalize to the broader population of non-twins. The current study analyzed data drawn from the National Longitudinal Study of Adolescent Health and findings suggested twins do not systematically differ from the general population of non-twins on many measures of behavior and development. Furthermore, the effects of specific covariates on measures of antisocial behavior did not appear to differ across twin status. In sum, evidence concerning the etiology of antisocial behavior (e.g., heritability estimates) gleaned from twin-based research is likely to generalize to the non-twin population.
