![]() ![]() ![]() The DSM-5 diagnostic criteria requires at least: 1 Criterion B item (questions 1-5), 1 Criterion C item (questions 6-7), 2 Criterion D items (questions 8-14), and 2 Criterion E items (questions 15-20). A score of 2 (Moderately on the likert scale ) or higher is an endorsed symptom. Given the PCL-5 questions closely reassembled the diagnostic criteria in the DSM-5-TR, a provisional PTSD diagnosis can be made based on the following rule. Extremely Severe – Average score above 3.265.Severe – Average score above 2.455 and less than or equal to 3.265.Moderate – Average score above 1.64 and less than or equal to 2.455.Mild – Average score above 1.23 and less than or equal to 1.64.Normal Range – Average score less than or equal to 1.23.These descriptors are determined by the distance from the normative mean: Symptom descriptors are also presented for the total score and each of the subscale scores. These scores range between 0 to 4, where higher scores represent higher severity. The average score can help determine elevated symptom clusters when comparing each of the four subscales. 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 within that subscale. Hyper-arousal (Criterion E, items 15-20, max score = 24).Negative alterations in cognition and mood (Criterion D, items 8-14, max score = 28).Avoidance (criterion C, items 6-7, max score = 8).Re-experiencing (criterion B, items 1-5, max score = 20).There are four subscales which match the four symptom clusters for PTSD within DSM-5: A normative percentile of 50 is indicative of an average score for someone who does not have PTSD, whereas a PTSD percentile of 50 is indicative of an average score for someone who is currently in care for PTSD. Percentiles are also presented for the total score in comparison to both a normative and clinical (PTSD) sample. ![]() Total scores can range from 0 to 80, with higher scores indicating greater PTSD symptom severity. The PCL-5 is widely used in clinical and research settings to screen for PTSD, assess symptom severity, and monitor treatment progress over time (Forkus et al., 2023). Individuals with hyperarousal symptoms may feel constantly on edge, as if they are in a state of heightened alertness or danger. ![]()
