The PCL-5 is easy to administer, and clinicians can be confident that results from the questionnaire yield high diagnostic accuracy without subjecting patients to unnecessary testing. Research studies have demonstrated evidence of improved patient outcomes ( Valenstein et al., 2009) and accurate detection of PTSD when clinicians include the PCL-5 in their toolkits ( Geier et al., 2018). It is often recommended that health practitioners include standardized psychological questionnaires in routine clinical assessment. The PCL-5 has been used in diverse clinical populations including first responders, veterans, trauma-exposed women. Recommendations from the National Center for PTSD suggest that the PCL-5 is a psychometrically sound measure of DSM-5 PTSD. A recent meta-analysis also found evidence for acceptable construct validity and the ability to index sensitivity to clinical change ( Forkus et al., 2023). The PCL-5 has demonstrated strong internal consistency, test-retest reliability, convergent and discriminant validity ( Blevins et al., 2015). In general, use of a total severity cutoff score to assist in a provision diagnosis tends to produce more reliable results than rules based on DSM-5 criteria alone. 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). 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).
