A Study on the Typology of Mental Health Issues among Disaster Victims and Their Transferring Influential Factors

Abstract

The purpose of this study is to classify latent subgroups of posttraumatic stress disorder, depression, and anxiety comorbidity among disaster victims and analyze their longitudinal changes. To do this, this study utilized data from the Disaster Victim Life Change Tracking Survey, which was conducted by the National Disaster Safety Research Institute. The study sample consisted of 1,069 disaster victims who participated in the 2nd and 4th waves of the survey. First, two years after the disaster, mental health latent subgroups among disaster victims were classified into three groups (the general, at-risk, and high-risk groups). Second, four years after the disaster, mental health latent subgroups among disaster victims were categorized into two groups (the general group and the at-risk group). Third, the probability of transitioning from the general group in the second year to the at-risk group in the fourth year was 10%, while disaster victims in the at-risk and high-risk groups in the second year had probabilities of transitioning to the at-risk group in the fourth year of 41.7% and 60.8%, respectively. Fourth, for those in the general group in the second year, the probability of remaining in the general group in the fourth year was higher when the disaster was a natural disaster, income was higher, and resilience was greater compared to transitioning to the at-risk group. Fifth, regarding victims in the high-risk group in the second year, as their age increased, the probability of transitioning to the at-risk group in the fourth year was higher than remaining in the general group. Based on these results, this study discussed practical and policy implications for interventions dealing with the comorbidity of mental health issues among disaster victims.
