The protective influence of social relationships on health is widely documented; however, not all relationships are positive, and negative aspects of relationships may be detrimental. Much less is known about the relationships characterized by both positivity and negativity (i.e., ambivalence). This article provides a theoretical framework for considering the influence of ambivalent relationships on physical health, including reasons why ambivalence should be considered separately from relationships characterized as primarily positive (supportive) or primarily negative (aversive). We introduce the social ambivalence and disease (SAD) model as a guide to understanding the social psychological antecedents, processes, and consequences of ambivalent relationships. We conclude by highlighting gaps in the literature and features of the SAD model that may serve as a guide to future research on potential health-relevant pathways of ambivalent relationships.

社会矛盾心理与疾病（SAD）：旨在理解矛盾关系对健康影响的理论模型。

社会关系对健康的保护性影响已被广泛记录；然而，并非所有关系都是积极的，关系的消极方面可能是有害的。人们对于同时具有积极性和消极性（即矛盾心理）的关系知之甚少。本文提供了一个理论框架，用于考虑矛盾关系对身体健康的影响，包括为什么应将矛盾关系与主要为积极（支持）或主要消极（厌恶）的关系分开考虑的原因。我们引入社会矛盾心理与疾病（SAD）模型作为理解矛盾关系的社会心理前因、过程和后果的指南。最后，我们强调了文献中的空白和 SAD 模型的特征，这可以作为未来研究矛盾关系的潜在健康相关路径的指南。
