Prevalence and Determinants of Chronic Post-Traumatic Stress Disorder After Floods

Abstract

Objective: To explore the prevalence and determinants of chronic post-traumatic stress disorder (PTSD) among flood victims. Methods: A cross-sectional survey was carried out in 2014 among individuals who had experienced the 1998 floods and had been diagnosed with PTSD in 1999 in Hunan, China. Cluster sampling was used to select 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, coping style was measured according to a Simplified Coping Style Questionnaire, and personality was measured by use of the revised Eysenck Personality Questionnaire Short Scale for Chinese. Data were collected through face-to-face interviews by use of a structured questionnaire. Multivariate logistic regression analysis was used to reveal the determinants of chronic PTSD. Results: A total of 123 subjects were interviewed, 17 of whom (14.4%) were diagnosed with chronic PTSD. Chronic PTSD was significantly associated with disaster stressors (odds ratio

Understanding the Relationship between Rainstorm-Related Experiences and PTSD among Chinese Adolescents after Rainstorm Disaster: The Roles of Rumination and Social Support

“…Consistent with previous studies ( Bokszczanin, 2007 ; Chen et al, 2015 ; Dixon et al, 2015 ), our findings suggest that rainstorm-related experiences can directly lead to PTSD. This supports the shattered world assumption ( Janoff-Bulman, 2010 ), which proposes that traumatic experiences can challenge people’s stable belief systems such that more negative cognition and emotion emerges ( Janoff-Bulman, 1989 ), and in turn more PTSD symptoms are elicited.…”

Long-term psychological outcomes of flood survivors of hard-hit areas of the 1998 Dongting Lake flood in China: Prevalence and risk factors

“…Personality traits are traditionally conceptualized as dimensions of individual differences in tendencies to show consistent patterns of feelings, thoughts, and actions across developmental periods and contexts [ 59 ]. The interface between personality and psychopathology is well established, and the trait of neuroticism has been reported to be a predictor of many psychological disorders, including PTSD and anxiety [ 60 , 61 ]. In this study, participants with emotional instability, indicating a high level of neuroticism, were at a higher risk of suffering from PTSD and anxiety a long time after the flood.…”

Impact of personality and social support on posttraumatic stress disorder after traffic accidents

“…[ 38 ] This study showed the neuroticism (N) and psychoticism (P) are independent factors for PTSD symptom score, as in Holeva V's study. [ 39 ] There is strong correlation between PTSD and negative emotions, including neuroticism, avoidance, novelty-seeking, and self-transcendence, and hostility, anger, and anxiety. [ 40 ] These findings may assist in further uncovering the etiology, identification, and prevention strategies of PTSD.…”
