Although there is a large body of research addressing predictors of relationship infidelity, no study to our knowledge has specifically addressed infidelity in a previous relationship as a risk factor for infidelity in a subsequent relationship. The current study addressed risk for serial infidelity by following adult participants (N = 484) longitudinally through two mixed-gender romantic relationships. Participants reported their own extra-dyadic sexual involvement (ESI) (i.e., having sexual relations with someone other than their partner) as well as both known and suspected ESI on the part of their partners in each romantic relationship. Findings from logistic regressions showed that those who reported engaging in ESI in the first relationship were three times more likely to report engaging in ESI in their next relationship compared to those who did not report engaging in ESI in the first relationship. Similarly, compared to those who reported that their first-relationship partners did not engage in ESI, those who knew that their partners in the first relationships had engaged in ESI were twice as likely to report the same behavior from their next relationship partners. Those who suspected their first-relationship partners of ESI were four times more likely to report suspicion of partner ESI again in their next relationships. These findings controlled for demographic risk factors for infidelity and held regardless of respondent gender or marital status. Thus, prior infidelity emerged as an important risk factor for infidelity in next relationships. Implications for novel intervention targets for prevention of serial relationship infidelity are discussed.
尽管有大量研究探讨了关系不忠的预测因素,但据我们所知,尚无研究专门探讨前一段关系中的不忠作为后续关系中不忠的风险因素。当前的研究通过对成年参与者(N = 484)进行纵向跟踪,考察其两段异性浪漫关系中的连续不忠风险。参与者报告了自己的婚外性行为(即与伴侣以外的人发生性关系),以及在每段浪漫关系中伴侣已知和疑似的婚外性行为。逻辑回归分析结果显示,与在第一段关系中未报告有婚外性行为的人相比,在第一段关系中报告有婚外性行为的人在接下来的关系中报告有婚外性行为的可能性高出三倍。同样,与那些报告其第一段关系中的伴侣没有婚外性行为的人相比,那些知道自己第一段关系中的伴侣有婚外性行为的人,报告其下一段关系中的伴侣有同样行为的可能性高出一倍。那些怀疑自己第一段关系中的伴侣有婚外性行为的人,在接下来的关系中再次怀疑伴侣有婚外性行为的可能性高出四倍。这些发现控制了不忠的人口统计学风险因素,且无论受访者的性别或婚姻状况如何均成立。因此,先前的不忠成为后续关系中不忠的一个重要风险因素。文中还讨论了预防连续关系不忠的新干预目标的意义。
