The PCL-5 is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. The PCL-5 has a variety of purposes, including:
The PCL-5 can be administered in one of three formats:
Several important revisions were made to the PCL in updating it for DSM-5:
The PCL-5 is a self-report measure that can be completed by patients in a waiting room prior to a session or by participants as part of a research study. It takes approximately 5-10 minutes to complete. Interpretation of the PCL-5 should be made by a clinician.
The PCL-5 can be scored in different ways:
Characteristics of a respondent's setting should be considered when using PCL severity scores to make a diagnosis. The goal of assessment also should be considered. A lower cutoff should be considered when screening or when it is desirable to maximize detection of possible cases. A higher cutoff should be considered when attempting to make a definitive diagnosis or to minimize false positives.
Good clinical care requires that clinicians monitor patient progress. 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. 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.
Change scores for PCL-5 are currently being determined. It is expected that reliable and clinically meaningful change will be in a similar range.
