Due to the current identification of PTSD as a recognized disorder, important concerns such as determinant of failure to recuperate from a neurosis and the advancement and assessment of effective treatments have recently started to be dealt with in research employing thorough methodology (Vasterling amp. Brewin, 2005). In this literature review, the diagnostic measure for PTSD will be discussed and the prevalence of PTSD related with different stressors will be considered. And then, the literature on current treatment outcome will be critically reviewed.The DSM-IV analysis of PTSD comprises six measures. The first is the distinguishing trauma (McLean amp. Woody, 2001). A distressing episode is described as one wherein: (a) the individual witnessed, experienced, or was faced with an incident that involved perceived or real danger to physical reliability or threat to life. and (b) the emotional response of an individual to this incident included severe anxiety, defenselessness, or shock (McLean amp. Woody, 2001). Psychological indicators of PTSD are grouped into three categories: (1) reexperiencing. (2) avoidance/numbing. and (3) increased arousal (Vasterling amp. Brewin, 2005).Based on the epidemiological data detailed by Helzer and associates (1987), more or less 1-2% of the overall population of the United States qualifies for PTSD (p. 1631), though it has been claimed that Helzer and associates miscalculated the frequency of the disorder (Foa amp. Meadows, 1997). Reflective epidemiological investigations of particular trauma populations determine the occurrence of PTSD at higher rates (Foa amp. Meadows, 1997). Resnick and colleagues (1993), for instance, discovered that women rape victims, 12.4% qualified for recent PTSD and 32% for lifetime PTSD (p. 986).
