Community Engagement for Disaster Risk Reduction (CEDRR): A Novel Community-Engaged Mixed Methods Approach for Measuring Impacts and Spillover Effects

Community-engaged research (CER) in disaster risk reduction requires novel approaches that move beyond raising awareness and instead employ methods that support and measure actual impacts on household risk reduction. This study introduces Community Engagement for Disaster Risk Reduction (CEDRR), a longitudinal CE-MMR approach that involves an initial dialogic engagement with a 6-month follow-up to examine how participants learned about risk, adopted protective actions, and shared insights within their social networks. By integrating quantitative indicators with qualitative impact narratives expressed during the follow-up in a joint display, CEDRR demonstrates how impacts emerge and evolve across time and place. CEDRR contributes to MMR by extending interventionalist traditions with a longitudinal design that captures nuanced participant-level change and traces its diffusion through communities.
