Table 4 Diagnostic utility of different PCL cutoff scores

From: The German version of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5): psychometric properties and diagnostic utility

PCL-5 Cutoff Sensitivity Specificity PPP NPP OE % PTSD according to this criterion
31 .88 .66 .81 .77 .79 67%
32 .87 .67 .81 .76 .79 66%
33 .86 .68 .81 .75 .79 65%
PCL-5 symptom scoring .84 .68 .81 .73 .78 64%
  1. Sensitivity probability that someone with a CAPS-5 diagnosis will test positive on the PCL-5, Specificity probability that someone without a CAPS-5 diagnosis will test negative on the PCL-5, PPP positive predictive power, NPP negative predictive power, OE overall efficiency, PCL-5 symptom scoring: each PCL-5 rated at least 2 (moderately) is treated as a symptom endorsed and the DSM-5 diagnostic rule is then used to establish a provisional PTSD diagnosis
