Post-Traumatic Stress Disorder

Post-traumatic stress disorders following disasters: a systematic review Summarize
This article is about post-traumatic stress disorders. Post-traumatic stress disorders is probably the most commonly studied post-disaster psychiatric disorder. This review aimed to systematically assess the evidence about post-traumatic following exposure to disasters (Neria, Nandi, & Galea, 2007).

The research is comprehensive because of the data that was used in the research starting from 1980 until it was terminated in 2007.

Design and the Methods
A systematic search was performed. Eligible studies for this review included reports based on the DSM criteria of PTSD symptoms (Neria, Nandi, & Galea, 2007). The time-frame for inclusion of reports in this review is from 1980 (when PTSD was first introduced in DSM-III) and February 2007 is when the literature search for this examination was terminated (Neria, Nandi, and Galea, 2007).

Method of Analysis
Neria, Nandi, & Galea (2007) identified 284 reports of PTSD following disasters published in peer-reviewed journals since 1980. Neria, Nandi, & Galea (2007) categorized them according to the following classification: (1) human-made disasters (n=90), (2) technological disasters (n=65), and (3) natural disasters (n=116). Since some studies reported on findings from mixed samples (e.g. survivors of flooding and chemical contamination) we grouped these studies together (n=13) (Neria, Nandi, & Galea, 2007).
