Assess understanding of core principles of risk communication in public health emergencies, focusing on audience segmentation (demographic, sociocultural, and risk-perception factors), message framing (gain vs. loss framing, clarity, and communicating uncertainty), and trust-building strategies (transparency, consistency, and credible messengers). Quiz items will include applied scenarios requiring selection and justification of segmentation and framing choices, evaluation of trust-building tactics for diverse populations, and short analyses of sample communication plans.
