Background:

Trust is an important component in romantic relationships. However, posttraumatic stress symptoms (PTSS) can alter an individual’s appraisal of others resulting in difficulties with interpersonal trust. Indeed, prior literature has established associations between PTSS and trust, and relations between trust and relationship distress. Even so, there is a dearth of research examining the association between PTSS and trust specifically within ones’ romantic relationship as well as how dyadic trust may help explain the relation between PTSS and overall relationship distress.

Method:

This study examined a sample of 57 opposite-sex adult community couples where at least one partner had a lifetime history of trauma-exposure. Mediated actor-partner interdependence modeling (APIMeM) examined the intraindividual and interpersonal pathways in the association between PTSS and relationship distress as well as potential sex differences.

Results:

Findings demonstrated actor and partner effects between dyadic trust and relationship distress; however, males’ dyadic trust was only marginally associated with their female partners’ relationship distress. Sex differences were demonstrated in the relation between PTSS and dyadic trust whereby females’ dyadic trust was related to their own and their partners’ PTSS. There was a partner effect between females’ PTSS on their male partners’ relationship distress but not from males’ PTSS to females’ relationship distress. Finally, females’ dyadic trust was supported as a full mediator between PTSS and relationship distress for all pathways in the model.

Conclusion:

There is a unique effect of females’ dyadic trust on the relation of PTSS and relationship distress. Future directions and clinical implications are discussed.

Dyadic信任作为创伤后压力症状与社区夫妻关系困扰之间的中介者

背景：

信任是恋爱关系中的重要组成部分。但是，创伤后压力症状（PTSS）可能会改变个人对他人的评价，从而导致人际信任困难。实际上，现有文献已经建立了PTSS与信任之间的关联，以及信任与关系困扰之间的关系。即便如此，仍缺乏研究来具体研究PTSS与信任之间在恋人关系中的关联，以及二元信任如何帮助解释PTSS与整体关系困扰之间的关系。

方法：

这项研究调查了57个异性恋成年社区夫妇的样本，其中至少一个伴侣有一生经历过创伤暴露史。中介演员-伴侣相互依存模型（APIMeM）研究了PTSS与关系困扰以及潜在的性别差异之间的个体和人际关系。

结果：

研究结果证明了二元信任和关系困扰之间的演员和伙伴效应；然而，男性的二元信任只与女性伴侣的恋爱困扰有关。在PTSS与二分信任之间的关系中证明了性别差异，其中女性的二分信任与自己和伴侣的PTSS相关。女性的PTSS对男性伴侣的关系困扰有伴侣效应，但从男性的PTSS到女性的关系困扰没有伴侣效应。最后，在模型中所有途径的PTSS与关系困扰之间，女性的二元信任得到了充分的支持。

结论：

女性的二元信任对PTSS的关系和关系困扰有独特的影响。讨论了未来的方向和临床意义。
