An analysis of domestic and foreign cohort studies of disaster victims can suggest directions for domestic cohort studies of disaster. Research papers on disaster cohorts were found with search engines such as PubMed and RISS. The key words used were disaster, trauma, cohort, and posttraumatic stress disorder (PTSD). Foreign research papers on human-made disaster (n=16), technological disaster (n=11), natural disaster (n=12), and domestic research papers on disaster (n=6) were reviewed. Analysis revealed that domestic cohort research on disaster victims is lacking compared to foreign countries. This results in the current limitations in planning for active intervention and support for disaster victims. To establish appropriate crisis intervention and management plans for disaster situations, a cohort study of disaster victims should be actively implemented through epidemiologic survey and assessment of risk factors on mental health, PTSD, depression, anxiety and other deleterious outcomes
