Am J Geriatr Psychiatry. 2014 Jun;22(6):545-50. doi: 10.1016/j.jagp.2013.03.009. Epub 2013 Sep 13.

Abstract

Objective: To assess the diagnostic performance of the PTSD Checklist (PCL) for three age groups (<50, 50-64, and ≥65 years).

Methods: The PCL was compared with the Clinician Administered PTSD Scale, a gold standard for the diagnosis of post-traumatic stress disorder. Receiver operating characteristic curves and the corresponding area under the receiver operating characteristic curve (AUC) and measures of sensitivity and specificity were used to assess the performance of and to determine optimal cutscores for the PCL across the three groups. Analyses were based on 858 randomly selected primary care patients who participated in a study conducted at four Veterans Administration medical centers.

Results: AUCs were high for all three age groups (87.55%-88.26%), and there were no significant differences in AUCs across age groups χ(2). Optimal cutscores, however, varied considerably: 24 for the oldest group, 34 for the middle group, and 43 for the youngest group.

Conclusion: Recommend use of lower PCL cutscore for older Veterans Administration primary care patients.
