A study conducted by the World Health Organization revealed that 10% of their respondents reported witnessing violence (21.8%) or experiencing interpersonal violence (18.8%), accidents (17.7%), exposure to war (16.2%), or trauma to a loved one (12.5%). It is likely that victims of these incidents might sit with lasting psychological trauma if not assisted. Symptoms of post-traumatic stress disorder are scary, anxiety-provoking, and intrusive, often having a significant negative influence on the client’s quality of life and daily functioning. The Davidson Trauma Scale (DTS) is a quick screening tool available to practitioners to evaluate the frequency and severity of symptoms in their clients. Although still corresponding to the DSM-IV criteria for PTSD, the outputs of the DTS provides practitioners with both a total PTSD score as well as scores for each cluster (intrusion, avoidance/numbing, and hyperarousal) to aid practitioners in effectively suggesting suitable intervention or treatment plans.
