Previous research has shown that positive intergroup contact among disadvantaged group members may predict a so‐called sedative effect according to which positive contact is associated with reduced support for social change. Conversely, positive contact is associated with increased support for social change toward equality among advantaged group members. This raises the important question of under which circumstances intergroup contact can encourage support for social change among both disadvantaged and advantaged groups. In this theoretical article, we tackle this question by introducing a new Integrated Contact‐Collective Action Model (ICCAM). We first provide an up‐to‐date review of how intergroup contact may promote or hinder social change for both disadvantaged and advantaged groups. We, then, use ICCAM to examine when the many forms of intergroup contact promote or hinder support for social change, proposing the existence of two different paths for disadvantaged and advantaged group members. Finally, we discuss the implications of the model for social intervention and make policy recommendations stemming from a review of available evidence.

群体间的接触与社会变革：一个综合的接触-集体行动模型

先前的研究表明，弱势群体成员之间的积极的群体间接触可以预测所谓的镇静作用，根据这种镇静作用，积极的接触与对社会变革的支持减少有关。相反，积极的接触与增加对有利于团体成员平等的社会变革的支持有关。这就提出了一个重要的问题，即群体间的联系在什么情况下可以鼓励双方支持社会变革弱势群体和优势群体。在这篇理论文章中，我们通过引入新的综合接触-集体行动模型（ICCAM）解决了这个问题。我们首先提供有关群体间接触如何促进或阻碍处境不利和处于有利地位的群体的社会变革的最新综述。然后，我们使用ICCAM来检查群体之间的多种形式的联系何时促进或阻碍了对社会变革的支持，并提出了对处于不利地位和处于有利地位的群体成员存在两种不同的途径。最后，我们讨论了该模型对社会干预的意义，并根据对现有证据的审查提出了政策建议。
