COVID-19 measures have necessarily disrupted vaccinations and have been detrimental to measles prevention. As of October 2021, nearly 41 countries had paused their measles campaigns, leaving more than 94 million people at risk of missing vaccines. Therefore, it is critical for public health officials to continue to provide resources, promote vaccination, and change behaviors despite the pandemic. The study’s purpose is to enhance the information-environment level, population-level, and system-level outcomes to determine infectious disease outbreak and measles outbreak communications effectiveness among parents. Methods: A 2020 web survey using a panel of 460 U.S. adults with children 10 years old or younger. Results: Infectious disease outbreak efficacy was the best individual predictor (? = 0.34, p < .001) of individuals’ information vetting intentions. Information vetting was the best predictor of information seeking intentions (? = 0.38, p < .001) and infectious disease outbreak history salience was the best predictor of information sharing intentions (? = 0.48, p < .001). Discussion: This Risk Communications Evaluation Framework extension demonstrates the applicability in understanding and predicting parents’ infectious disease outbreak information responses, mapping contributing factors, information-environment level outcomes, population-level outcomes, and system-level outcomes to determine risk communications effectiveness. The two new population-level outcomes demonstrate the importance of understanding infectious disease outbreak communications’ dynamics and complexities. Moreover, this study offers public health professionals insight into parents’ infectious disease outbreak information processing and response mechanisms, whom, with varied infectious disease outbreak history salience and involvement level, are confronted by multiple infectious disease outbreak challenges.

新冠疫情防控措施不可避免地打乱了疫苗接种工作，并对麻疹预防工作造成了不利影响。截至2021年10月，已有近41个国家暂停了麻疹疫苗接种行动，导致超过9400万人面临疫苗接种缺失的风险。因此，即便仍处于新冠疫情大流行期间，公共卫生从业者仍需持续投入资源、推广疫苗接种并引导民众调整行为，这一点至关重要。
本研究旨在优化信息环境层面、人群层面与系统层面的相关成果，以明确家长群体对传染病暴发及麻疹暴发的信息传播有效性。
研究方法：本研究于2020年开展一项网络调查，调研样本为460名育有10岁及以下子女的美国成年人组成的固定调研面板。
研究结果：传染病暴发信息认知效能是个体信息审核意向的最佳独立预测因子（β=0.34，p<0.001）；信息审核行为是信息寻求意向的最佳预测因子（β=0.38，p<0.001）；而传染病暴发历史显著性是信息分享意向的最佳预测因子（β=0.48，p<0.001）。
讨论：本研究对风险传播评估框架（Risk Communications Evaluation Framework）的拓展，验证了其在理解与预测家长群体对传染病暴发信息的反应、梳理影响因素、映射信息环境层面、人群层面及系统层面成果以判定风险传播有效性方面的适用性。两项新增的人群层面成果，凸显了理解传染病暴发信息传播动态性与复杂性的重要意义。此外，本研究为公共卫生从业者提供了关于家长群体传染病暴发信息处理与反应机制的洞见——这类群体面临多重传染病暴发相关挑战，且其传染病暴发历史显著性与参与程度各不相同。
