Utility

The CPSS provides a symptom severity score by assessing PTSD symptoms in three clusters, reexperiencing, avoidance, and arousal (the three clusters defined by the DSM-IV). Its classification as a self-report measure requires "minimal clinician and administration time". It should be seen as a practical tool for use in schools, communities, and research settings. [1]

"Results suggest a large discrepancy between rates of probable PTSD identified through standardized assessment and during the emergency room psychiatric evaluation (28.6% vs. 2.2%). Upon discharge, those with probable PTSD were more than those without to be assigned a diagnosis of PTSD (45% vs. 7.1%), a comorbid diagnosis of major depressive disorder (30% vs .14.3%), to be prescribed an antidepressant medication (52.5% vs. 33.7%), and to be prescribed more medications. The underidentification of trauma exposure and PTSD has important implications for the care of adolescents given that accurate diagnosis is a prerequisite for providing effective care. Improved methods for identifying trauma-related problems in standard clinical practice are needed" [2]

The CPSS scale assesses avoidance and change of activities, which may not accurately reflect pathology. This could possibly result in higher PTSD prevalence estimations. In a study, the CPSS scale correctly classified 72.2% of children. Nearly one quarter of children were misclassified and 5.6% were misclassified (false negative) [3]
