![]() 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). In 2013 DSM-5 created a new category called Trauma- and Stressor-Related. 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) The proposed posttraumatic stress disorder (PTSD) criteria for the International Classification of Diseases (ICD) 11th revision are simpler than the criteria in ICD-10, DSM-IV or DSM-5.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).
