Posttraumatic stress disorder (PTSD) is a widespread disorder that affects certain individuals psychologically, behaviorally, and emotionally following the experience of a traumatic event (Lee et al., 2005, p. 135). However, because of inconsistencies regarding the percentage of individuals who experience PTSD and the percentage of individuals who subsequently develop PTSD, researchers hypothesize that both biological and environmental factors contribute to the development of PTSD (Wolf et al. 2010, p. 328). In order gain a better understanding of this disorder and to discover contributing and predicative factors which contribute to the development of PTSD, this paper analyses the historical context and prevalence of PTSD, the biological and environmental contributing factors, and types of intervention used to mediate the effects of PTSD. In conclusion, the paper advocates the interrelated nature of environmental and biological influences on the development of PTSD and suggests future areas of research which may increase an interventionists ability to assist an individual suffering from PTSD.
Posttraumatic Stress Disorder
Posttraumatic Stress Disorder (PTSD) is a severe anxiety disorder that may occur after an individual has experienced one or more intense or traumatic experiences (Friedman, 2007). These experiences may include anything that causes an individual to experience trauma such as combat exposure, sexual assault, physical abuse, or a life-threatening situation (Gersons & Carlier, 1992). However, not all individuals who are exposed to traumatic level of stress develop PTSD which suggests that some individuals may be more susceptible to the disorder than others (Lee et al., 2005, p. 135). Consequently, research regarding PTSD typically involves an examination of both environmental and biological factors which may contribute to the development of PTSD. Most researchers agree that while PTSD may partially arise from an individual’s... [continues]
