![]() ![]() Evidence for the PCL for DSM-IV suggests that a 5-10 point change represents reliable change (i.e., change not due to chance) and a 10-20 point change represents clinically significant change. Good clinical care requires that clinicians monitor patient progress. A higher cut-point score should be considered when attempting to make a provisional diagnosis or to minimize false positives. A lower cut-point score should be considered when screening or when it is desirable to maximize detection of possible cases. The goal of assessment also should be considered. Further, because the population and the purpose of the screening may warrant different cutoff scores, users are encouraged to consider both of these factors when choosing a cutoff score.Ĭharacteristics of a respondent's setting should be considered when using PCL-5 severity scores to make a provisional diagnosis. Initial research suggests that a PCL-5 cutoff score between 31-33 is indicative of probable PTSD across samples.A provisional PTSD diagnosis can be made by treating each item rated as 2 = "Moderately" or higher as a symptom endorsed, 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).DSM-5 symptom cluster severity scores can be obtained by summing the scores for the items within a given cluster, i.e., cluster B (items 1-5), cluster C (items 6-7), cluster D (items 8-14), and cluster E (items 15-20). ![]() ![]()
