Post-Traumatic Stress Disorder (PTSD) is a psychological consequence experienced by many disaster survivors. Risk factors for PTSD among this population have been extensively documented. Most recently, studies have acknowledged the psychological impact disasters also have on responders. Common consequences for this population also include PTSD but few studies have examined the risk factors associated with PTSD in this population. This study aims to determine the prevalence of as well as risk factors for PTSD among Chinese medical rescue workers one year after their response to the 2008 Wenchuan earthquake in China.
A sample of 337 medical rescue workers who had performed response work within the first three months after the earthquake completed a website questionnaire 14- 17 months after their response work. The questionnaire included questions on rescue
work experience, pressure management strategies, general health, the impact of the events, coping style, personality traits and demographic factors. Presence of PTSD was determined by a score greater than 33 on the Impact of Event Revised-Scale.
Seventeen percent (95% CI: 13%-21%) of the responders tested positive for clinical PTSD after an average of 14 months. Similar to the survivors of disasters, responders' PTSD is associated with getting injured or sick and a lack of social support. The multivariate regression showed that neurotic personality, passive coping style, communication with relief headquarters, and having been injured while performing response work were significantly associated with PTSD.
Future research should further examine the relationship between these variables and PTSD and identify preventive measures that could mitigate their impact. For example, additional logistical measures could ensure that the rescue workers have regular contact with headquarters during the response. Similarly, the number of injuries might be reduced with safety training and equipment.
