Most health research focuses on the independent associations of positive or negative aspects of close relationships with health outcomes. A small but growing literature has begun to examine interactive effects of positive and negative aspects. These interactive effects frequently predict health independently or above-and-beyond main effects of either the positive or the negative aspects, suggesting unique relationship processes or emergent features of these close relationship patterns. Our goal in this review is to lay out the existing approaches to studying the interactive effects of positive and negative aspects of close relationships, and to review available evidence linking these interactive effects to health outcomes. We conclude by discussing important unresolved issues and highlighting critical directions for future research.

亲密关系和健康：正面和负面方面的互动影响

大多数健康研究关注与健康结果密切相关的正面或负面方面的独立联系。少量但正在增长的文献已开始研究积极和消极方面的互动影响。这些互动效应经常独立地或以正面或负面方面的主要作用预测健康状况，表明这些紧密关系模式的独特关系过程或新出现的特征。我们在这篇综述中的目标是提出研究亲密关系正面和负面方面的相互作用影响的现有方法，并综述将这些相互作用与健康结果相关联的现有证据。最后，我们讨论了尚未解决的重要问题，并强调了未来研究的关键方向。
