风险沟通可用于告知、说服和促进公众对减轻和准备灾害风险的支持。一些常见的风险沟通做法，如使用基于恐惧的呼吁，可能会无意中引发适应不良行为。宣传册、电影或广告可能只是一项更大的危险准备运动的一部分，在广泛部署之前，可以而且应该分别测试这些物品的有效性和有效性。本文旨在介绍一种调查工具--25项抗震建筑知识与意见量表(EKO)的研制。这个量表是为了测试一种非紧急通信干预措施，旨在鼓励学校抗震建设。它被用于一项随机对照试验，测量观看20分钟电影后结果的变化(试验结果在其他地方报道)。这部干预电影的主角是尼泊尔的社区成员，他们为确保学校建筑的地震安全而努力。研究参与者是761名成年社区成员，他们居住在建筑需要抗震的学校。因子分析得到知识、可行性、愿意帮助学校和愿意推荐他人四个问卷分量表，解释了55.7%的变异。内部一致性是可以接受的，克朗巴赫的α为0.78-0.93，但知识因素除外(α=0.48)。EKO量表可以用来衡量其他环境中的风险沟通。对EKO量表和其他类似问卷的进一步开发和应用进行研究，可能有助于评估风险沟通干预措施，并有助于提高对影响干预效果的因素的理解。
Risk communications can be used to inform, persuade and facilitate public support for hazard risk mitigation and preparedness. Some common risk communications practices, such as the use of fear-based appeals, may inadvertently trigger maladaptive behavior. A brochure, film or advertisement may be just one part of a larger campaign to promote hazard readiness, and these items can and should be tested separately for efficacy and effectiveness prior to broad deployment. The purpose of this article is to show the development of a survey instrument, the 25-item earthquake-resistantconstruction knowledge and opinions (EKO) scale. This scale was created to test a non-emergency communications intervention designed to encourage earthquake-resistant school construction. It was utilized in a randomized controlled trial measuring change in outcomes after viewing a 20-minute film (trial results are reported elsewhere). The intervention film featured community members in Nepal who had worked toward making their school buildings earthquake safe. Study participants were 761 adult community members at schools with buildings in need of seismic work. Factor analysis yielded four questionnaire subscales labeled knowledge, feasibility, would-help-school and would-recommend-to-others, accounting for 55.7 % of the variance. Internal consistency was acceptable, with Cronbach’s α of 0.78–0.93 for all but the knowledge factor (α = 0.48). The EKO scale may be adapted to measure risk communications in other settings. Research on further development and application of the EKO scale and other similar questionnaires may facilitate the evaluation of risk communication interventions and help improve understanding of factors that contribute to intervention effectiveness.
