Did Disaster Risk Communication Workshop Improve Disaster Risk Reduction Literacy?:

Impact Evaluation Based on Propensity Score Analysis

Abstract

This study aimed to evaluate the impact of disaster risk communication workshops participation on disaster risk reduction literacy that were held in Onoji and Itoshima cities. The subjects consisted of those who responded to the post-workshop surveys (n=321). Propensity score analyses were performed to infer the causal effects on the disaster risk reduction literacy. The results showed that full workshop participation significantlly improved workshop participants' understanding of threats. The risk of non-balanced analysis and the efficacy of propensity score balancing were discussed.
