Mass gatherings are routinely viewed as posing risks to physical health. However, social psychological research shows mass gathering participation can also bring benefits to psychological well‐being. We describe how both sets of outcomes can be understood as arising from the distinctive forms of behavior that may be found when people—even strangers—come to define themselves and each other in terms of a shared social identity. We show that many of the risks and benefits of participation are products of group processes; that these different outcomes can have their roots in the same core processes; and that knowledge of these process provides a basis for health promotion interventions to mitigate the risks and maximize the benefits of participation. Throughout, we offer practical guidance as to how policy makers and practitioners should tailor such interventions.

通常，群众聚会被视为对身体健康构成威胁。但是，社会心理学研究表明，群众参与也可以为心理健康带来好处。我们描述了如何将两组结果理解为源自人们甚至是陌生人来以共同的社会身份来定义自己和彼此时发现的独特行为形式。我们证明了参与的许多风险和收益是团队过程的产物；这些不同的结果可以源于相同的核心流程；并且对这些过程的了解为健康促进干预措施提供了基础，以减轻风险并最大程度地提高参与的利益。自始至终，
