Communication with local officials, self-efficacy, and individual disaster preparedness : a case study of rural northwestern China

Abstract

Promoting individual disaster preparedness is one of the most effective ways to reduce disaster risk. Effective disaster risk communication is widely known to motivate individuals to take protective measures. However, the mechanisms underlying the communication of risk, particularly between local officials and individuals, and its effects on individuals' disaster preparedness are still unclear. This study established a moderated mediation model to investigate the mediating and moderating roles of individuals' level of disaster preparedness knowledge and self-efficacy, respectively, with a focus on local officials as the disaster information source. To test this conceptual model, 1080 villagers from Weinan city, Shaanxi province, China were randomly selected and interviewed. The results showed that frequent interpersonal communication with local officials enhanced villagers' disaster preparedness. However, this relationship was mediated by the extent of villagers' disaster preparedness knowledge. Moderated mediation analysis further indicated that those with a higher level of self-efficacy were more likely to prepare for disasters after receiving disaster risk-reduction information with village officials, but this effect was not significant for villagers with low self-efficacy. These findings indicated that individuals' preparedness level can be increased if local officials regularly communicate disaster risk reduction knowledge to villagers, and that this effect is stronger for individuals with a higher level of self-efficacy.
