Disaster management agencies invest differing levels of resources into guiding communities to get ready for a range of hazards, and are increasingly turning to community engagement as a way of increasing preparedness. This paper presents a systematic literature review that reports on the effect of community communication and engagement techniques that have been used in a hazard preparedness context. The review findings suggest that most community engagement techniques are effective in generating some level of increased preparedness. For techniques that were found not to work, lack of benchmarking research, context and skill levels of those implementing the engagement were thought to be at fault rather than structural or conceptual problems with the technique itself. Face to face techniques were more consistently successful than mass media campaigns. However, all of the intervention types reported had some measure of success, even though there were individual failures. The 41 studies included used a wide variety of research methods that also varied greatly in rigor and replicability. Agency efforts to engage communities in preparedness should include a wide range of techniques that work together to change behaviour, including face-to-face community engagement that triggers and supports community-led preparedness activity.

灾难管理机构投入了不同级别的资源来指导社区为各种灾害做好准备，并且越来越多地转向社区参与，以此来提高防范能力。本文提供了系统的文献综述，报告了在灾害防范环境中使用的社区沟通和参与技术的效果。审查结果表明，大多数社区参与技术都可以有效地提高准备水平。对于发现无效的技术，人们认为缺乏基准研究，实施项目参与人员的背景和技能水平是错误的，而不是技术本身的结构或概念问题。面对面的技术比大众媒体的运动更为成功。但是，报告的所有干预类型都有一定程度的成功，即使有个别失败也是如此。包含的41项研究使用了各种各样的研究方法，这些方法在严谨性和可复制性上也相差很大。机构为使社区参与备灾而做出的努力应包括广泛合作以改变行为的各种技术，包括触发并支持社区主导的备灾活动的面对面社区参与。
