Posttraumatic stress disorder among professional and non-professional rescuers involved in an earthquake in Taiwan.

This study investigated the prevalence of posttraumatic stress disorder (PTSD) among professional and non-professional rescue workers involved in the 1999 Chi-Chi Earthquake in Taiwan. One month following the disaster, 252 rescue workers (167 professional rescue workers, 85 non-professional volunteers) were surveyed with the Chinese version of the Davidson Trauma Scale (DTS-C) and the Chinese version of the SPAN (SPAN-C). Non-professional rescuers had significantly higher scores than professional rescuers on both the DTS-C and the SPAN-C.
