While community psychologists often work with coalitions, these entities engage in a wide range of activities and structures that are not well defined within the field. In this paper, we explore the following questions: (a) What are the characteristics of coalitions community psychologists study? (b) What are the themes in the way authors define coalitions in their work? To address these questions, we conducted a systematic review of articles about coalitions in journals serving community psychologists. Findings suggest coalitions in community psychology can be characterised by a focus on a wide variety of local level community issues and include a diverse group of stakeholders. Coalitions are defined by a focus on three types of coordination: knowledge coordination, negotiated coordination, and action coordination. These types of coordination are used to address specific problems coalitions encounter and define the goals and techniques appropriate for resolving them.

什么是联盟？社区心理学联盟的系统评价

虽然社区心理学家经常与联盟合作，但这些实体参与的活动和结构范围广泛，在该领域没有明确定义。在本文中，我们探讨了以下问题：（a）联盟社区心理学家研究的特点是什么？(b) 作者在作品中定义联盟的方式的主题是什么？为了解决这些问题，我们对服务于社区心理学家的期刊中关于联盟的文章进行了系统审查。调查结果表明，社区心理学联盟的特点是关注各种地方层面的社区问题，并包括不同的利益相关者群体。联盟的定义侧重于三种类型的协调：知识协调、协商协调和行动协调。这些类型的协调用于解决联盟遇到的特定问题，并定义适合解决这些问题的目标和技术。请参阅补充材料部分以查找本文的社区和社会影响声明。
