Scale available from the National Center for PTSD at References (PCL-5)īlevins, C. Weathers, F.W., Litz, B.T., Keane, T.M., Palmieri, P.A., Marx, B.P., & Schnurr, P.P. Response: 5-point Likert (0 = "Not at all" to 4 = "Extremely").Item: In the past month, how much were you been bothered by: "Repeated, disturbing, and unwanted memories of the stressful experience?".We recommend following the DSM-IV recommendations until new information is available. It is expected that reliable and clinically meaningful change will be in a similar range. Therefore, it was recommended to use 5 points as a minimum threshold for determining whether an individual has responded to treatment and 10 points as a minimum threshold for determining whether the improvement is clinically meaningful using the PCL for DSM-IV.Ĭhange scores for PCL-5 are currently being determined. 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.
