This study investigates the role of couple identity gaps in romantic partners' communicative and physiological management of stress during a conflict-inducing discussion task. A total of 118 couples participated in a laboratory study in which they engaged in a conflict-inducing discussion. Perceptions of intra- and extrarelationship couple identity gaps were associated with greater self-reported anxiety and stress for men and greater negativity for women during the conversation. Extrarelationship identity gaps were also significantly associated with heightened cortisol and (salivary alpha-amylase) sAA reactivity and delayed recovery, especially for women. The study extends the research on couple identity by introducing the concept of identity gaps into relational contexts to help explain why couples vary in their ability to manage stress.

夫妻身份差距，冲突处理以及浪漫关系中的生物和自我报告的压力

这项研究调查了在引发冲突的讨论任务中，情侣身份差异在浪漫伴侣的压力沟通和生理管理中的作用。共有118对夫妇参加了实验室研究，他们在其中进行了引发冲突的讨论。在对话期间，对内部和外部关系对情侣身份差距的感知与男性自我报告的焦虑和压力增加以及女性的负面情绪更大有关。关系外身份差异也与皮质醇和（唾液α-淀粉酶）sAA反应性升高以及恢复延迟有关，尤其是对女性而言。这项研究通过将身份差距的概念引入关系情境中，扩展了对夫妇身份的研究，以帮助解释为什么夫妻在压力承受能力上有所不同。
