Negative alterations in cognition and mood (criterion D).Severity scores for clusters of questions are also calculated to help evaluate the diagnostic criteria for PTSD from the DSM-5: Research suggests that a total symptom severity score of 31 or higher is indicative of probable PTSD across samples, but different clinicians may wish to consider different cutoff scores for their particular population. The version of the PCL-5 included in Creyos Health does not include optional items about a specific traumatic event (criterion A). Items are summed to provide a total symptom severity score (range = 0-80). Respondents are asked to rate how bothered they have been by each of 20 items in the past month on a 5-point Likert scale ranging from 0 (“Not at all”) to 4 (“Extremely”). The questionnaire evaluates the presence and severity of symptomatology based on 20 questions. The PCL-5 is intended to assess patient symptoms occurring in the past month. Ease of administration provides the opportunity for clinicians to simply yet effectively monitor PTSD symptoms of patients. The computerized version of the PCL-5 featured within Creyos Health can be completed by patients in the clinic or at home, and results are automatically scored and summarized. It takes approximately 5-10 minutes to complete, and is primarily used to monitor symptom change during and after treatment, screen individuals for PTSD, and assist in making a provisional PTSD diagnosis. Items on the PCL-5 correspond with DSM-5 criteria for PTSD. The Post-Traumatic Stress Disorder Checklist for DSM-5 is a 20-item self-report measure that assesses the presence and severity of PTSD symptoms ( Weathers et al., 2013). Clinicians and research specialists commonly administer the PCL-5 to screen for the presence of PTSD and track the severity of symptoms in various patient populations, as it is important to measure the effects of PTSD when treating its symptoms or comorbid disorders. The PCL-5 is a widely used self-rated assessment tool that provides both diagnostic and symptom severity assessment ( Cohen et al., 2014). doi: 10.12140/.Post-traumatic stress disorder (PTSD) is a serious mental health condition associated with a range of negative health effects, including neurobiological impacts ( Sherin & Nemeroff, 2011). Preliminary Evaluation of the Psychometric Properties of the PTSD Checklist for DSM – 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. 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).
