The roles of genetic and environmental influences on stressful life events were examined in 3938 twin pairs (MZ, same-sex DZ, and opposite-sex DZ) using a sex-limitation model. Life events were assessed by personal interview, and were categorized as being either personal (i.e., events that occur directly to the individual) or network (i.e., events that occur to someone within the individual's social network, thus affecting the individual indirectly). Consistent with previous reports, genetic factors were found to exert more influence on personal events than network events. Genetic correlations between males and females suggest that many of the same genetic factors are acting within both genders.
利用性别限制模型，在3938对双胞胎（同卵双胞胎、同性异卵双胞胎和异性异卵双胞胎）中研究了遗传和环境因素对压力性生活事件的影响。通过个人访谈评估生活事件，并将其分为个人事件（即直接发生在个体身上的事件）或网络事件（即发生在个体社交网络中的某个人身上从而间接影响个体的事件）。与之前的报告一致，发现遗传因素对个人事件的影响比对网络事件的影响更大。男性和女性之间的遗传相关性表明，许多相同的遗传因素在两性中都起作用。
