About the PCL-5
PCL-5: developed by staff of the VA National Center for PTSD; in the public domain per ptsd.va.gov. Items reproduced from the Standard form (Aug 2023).
The PCL-5 is the PTSD Checklist for DSM-5, published by the US Department of Veterans Affairs National Center for PTSD (Weathers, Litz, Keane, Palmieri, Marx and Schnurr, 2013). Its 20 items assess the 20 DSM-5 symptoms of PTSD, each rated 0 (not at all) to 4 (extremely) over the past month, for a total severity score of 0 to 80. The National Center states that initial research suggests a cutoff between 31 and 33 is indicative of probable PTSD across samples, that a lower cut point suits screening and a higher one suits a provisional diagnosis, and that interpretation of the PCL-5 should be made by a clinician. The National Center also describes reading the items by DSM-5 symptom cluster, counting any item rated 2 (moderately) or higher, to reach a provisional diagnosis.
How this page scores it: it adds your answers into a total of 0 to 80, and reads the result against the bands the source publishes: 0 to 30 is below the probable-ptsd cut-point; 31 to 80 is at or above the probable-ptsd cut-point. Every band's wording on the result page is ours, written from the source's guidance for that range, and a result at or above the follow-up threshold says so in plain words rather than as a color.
Scored 0 to 80 by summing the 20 items. The VA states a cut-point of 31 to 33 is indicative of probable PTSD across samples, with the threshold adjusted by setting and purpose. Only a clinician can diagnose PTSD. The instrument is reproduced as published and scored the way its published source scores it. A screening questionnaire estimates symptom severity over the past month; only a clinician can diagnose, and scores can be elevated by grief, medical illness or medications.
