PTSD is defined by four symptom clusters: avoidance, negative alterations in cognition and mood, intrusion, and hyperarousal per DSM-5. The transition from DSM IV to DSM-V acknowledges this inconsistency, made evident by the additional criteria specific to PTSD for children six years or younger.

Children often react differently to stressful events, and because of this, the pediatric phenomenology of PTSD differs from that of adults. It has been suggested that a substantial number of children have gone inappropriately undiagnosed because of the insufficient sensitivities of previous guidelines. Moreover, recent studies have unmasked unsettling discoveries regarding pediatric considerations in the setting of PTSD. Not to be misled by the putative simplistic nature of the etiology, the consequent psychiatric sequelae can, in turn, be debilitating. The temporal association between the event exposure and the subsequent symptom manifestation is not simply a post hoc fallacy. Thus, the causal nature of posttraumatic stress disorder (PTSD) places it in the company of a scant few psychiatric diagnoses where etiology is known. To the detriment of humanity, these endeavors frequently resulted in fruitless pursuits, as we still can only postulate the etiologies of many illnesses. Since time immemorial, scientists have pursued the ever-elusive causal origins of disease processes. Traumatic events may include incidents that involve serious harm to self or others and include accidents, natural disasters, sexual or physical trauma, natural disasters, and violence. doi: 10.12140/.Posttraumatic stress disorder (PTSD) is a mental disorder that may develop in some children and adolescents after exposure to a traumatic event. Preliminary Evaluation of the Psychometric Properties of the PTSD Checklist for DSM – 5. Scale available from the National Center for PTSD at ReferencesĬohen, J., et al. (2013).The PTSD Checklist for DSM-5 (PCL-5). Weathers, F.W., Litz, B.T., Keane, T.M., Palmieri, P.A., Marx, B.P., & Schnurr, P.P. If the scale is used to track symptoms over time, a minimum 10 point change represents clinically significant change (as based on the PCL for DSM-IV change scores). Examine items rated as 2=”Moderately” or higher as an endorsed symptom, then following the DSM-5 diagnostic rule which requires at least: 1 B item (questions 1-5), 1 C item (questions 6-7), 2 D items (questions 8-14), 2 E items (questions 15-20).This cut-off has high sensitivity (.78) and specificity (.98) (Cohen et al., 2015). A cut-off raw score is 38 for a provisional diagnosis of PTSD.There are two methods for determining a provisional PTSD diagnosis. These scores range between 0 to 5, where higher scores represent higher severity.Ġ = Not at all 1 = A little bit 2 = Moderately 3 = Quite a bit 4 = Extremely In addition to a raw score being presented, a “mean score” is also computed, which is the subscale score divided by the number of items. Hyper-arousal (items 15-20 – max score = 24).Negative alterations in cognition and mood (items 8-14 – max score = 28).Re-experiencing (items 1-5 – max score = 20).Scores consist of a total symptom severity score (from 0 to 80) and scores for four subscales: In a student validation sample (n = 2490) PTSD prevalence was 1.4% using both methods. There was also a high correlation between the two scoring methodologies: symptom severity and diagnostic classification scoring methods (Cohen et al., 2015). PCL-5 validation studies show all four criterion scales demonstrate high internal consistency (Cohen et al., 2015). The PCL-5 can be used to monitor symptom change, to screen for PTSD, or to make a provisional PTSD diagnosis. Negative alterations in cognition and mood (criterion D).Included in the scale are four domains consistent with the four criterion of PTSD in DSM-5: The PCL-5 is a 20 item self-report measure of the 20 DSM-5 symptoms of Post Traumatic Stress Disorder (PTSD).
