he objective of the study was to estimate the chronicity rate and to identify the prognostic factors of posttraumatic stress
disorder (PTSD) in flood victims. Simple cluster sampling was used to select subjects from 540 flood victims diagnosed
with PTSD in our 2000 study. We ascertained chronic PTSD using the same questionnaire (PTSD Checklist-Civilian version) as
our previous study, according to DSM-IVcriteria. Data were collected in face-to-face interviews and analyzed using univariate
analysis. A total of 76 subjects (42.0% of the selected subjects) were interviewed. The chronicity rate of PTSD was 17.1%.
The current occurrences of re-experiencing, avoidance/numbing and hyper-arousal symptom groups were 82.9%, 17.1% and
51.3%, respectively. Significant prognostic factors for chronic PTSD include smoking status, alcohol use status, frequency
of general collective action, and financial aid situation. Our findings indicated that PTSD can persist 13 years after flood.
The occurrence of avoidance/numbing symptom cluster is the most important criterion for chronic PTSD. Social behavior
characteristics, represented by frequency of general collective action, are important predictors of chronic PTSD.
