Abstract
Objective: To explore the prevalence and determinants of chronic posttraumatic stress disorder (PTSD) among flood victims.
Method: A cross-sectional survey was carried out in 2014 among individuals who had suffered floods and diagnosed with
PTSD in 1998 in Hunan, China. Cluster sampling was used to select the subjects from the areas that had been surveyed in
1999. PTSD was diagnosed according to DSM-IV criteria, social support was measured according to a Social Support Rating
Scale (SSRS), coping style was measured according to a Simplified Coping Style Questionnaire (SCSQ), and personality was
measured by Eysenck Personality Questionnaire Short Scale Revised China (EPQ-RSC). Data were collected through faceto-
face interview using a structure questionnaire. Binary logistic regression analysis was used to reveal the determinants of
chronic PTSD.
Results: Out of a total of 123 subjects interviewed, 5 subjects were excluded for the incomplete information, 17 (14.4%) were
diagnosed as having chronic PTSD. Chronic PTSD was significantly associated with disasters stressors (odds ratio [OR] 1.736,
95% confidence interval [CI], 1.220~2.469), nervousness (OR 1.086, 95%CI, 1.011~1.168), and social support (OR 0.848,
95CI%, 0.737~0.977).
Conclusions: Chronic PTSD in flood victims is significantly associated with disasters stressors, nervousness and social support.
They may play important roles in identifying the high risk group of chronic PTSD.
