This study investigates extradyadic sex (EDS) among contemporary opposite-sex married and cohabiting young adults and examines how EDS is associated with union dissolution. By analyzing data from 8301 opposite-sex spouses and cohabiters in the National Longitudinal Study of Adolescent to Adult Health, we estimate the prevalence of self-reported EDS, reports of partners' EDS, and reports of mutual EDS (i.e., both partners' engagement in EDS). Roughly 1 in 4 respondents reported that either they, their partner or both engaged in EDS. Young men were more likely than women to self-report EDS, while young women were more likely to report partners' EDS. Relative to no EDS, partners' EDS was associated with union dissolution, but self-reported EDS and mutual EDS were not. A partner's EDS was also associated with union dissolution relative to self-reported EDS. Associations between a partner's EDS and dissolution were consistent among spouses and cohabiters and among men and women.
本研究调查了当代异性已婚和同居的年轻成年人中的婚外性行为（EDS），并探讨了婚外性行为与关系解体之间的关联。通过分析“青少年到成人健康全国纵向研究”中8301名异性配偶和同居者的数据，我们估计了自我报告的婚外性行为、伴侣的婚外性行为报告以及双方都有婚外性行为（即双方都参与婚外性行为）的报告的发生率。大约四分之一的受访者报告称，他们自己、他们的伴侣或双方都参与了婚外性行为。年轻男性比女性更有可能自我报告有婚外性行为，而年轻女性则更有可能报告伴侣有婚外性行为。与没有婚外性行为相比，伴侣的婚外性行为与关系解体有关，但自我报告的婚外性行为和双方都有婚外性行为则不然。相对于自我报告的婚外性行为，伴侣的婚外性行为也与关系解体有关。伴侣的婚外性行为与关系解体之间的关联在配偶和同居者以及男性和女性中是一致的。
