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

Table 4 Diagnostic utility of different PCL cutoff scores

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%

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
