The Use of Public Health Indicators to Assess Individual Happiness in Post-Disaster Recovery

Very few studies have examined the influential factors of survivors' feelings of happiness in the context of nuclear accidents. This paper aims to fill this gap with reference to the recovery process in Fukushima City following the 2011 Tohoku Earthquake Tsunami in Japan.

Open access data were sourced from the 2015 Social Survey on Living and Disaster Recovery (SSLDR) (N = 1439) of Fukushima citizens. Pearson's Chi-square Test and the t-test were employed to examine gender differences with regard to happiness and exploratory variables. Following this, a multiple linear regression analysis was conducted to investigate the determinants of happiness.

The results showed that, compared to females, male respondents were unhappier and reported more property loss and less neighborhood connectedness. Individuals' mental and physical health and neighborhood connectedness were found to be significantly correlated with their happiness. However, the disaster-related variables of people's evaluation of recovery achievement, concerns around the health impacts of radiation, property loss in the disaster, and experiences of casualty, had no effects on happiness.

These findings indicate that policies and countermeasures dealing with disaster recovery over the long term should continuously focus on health issues and social relationships.
