Research utility of a CAPS ‐IV and CAPS‐5 hybrid interview: Posttraumatic stress symptom and diagnostic concordance in recent‐era U.S. veterans

AbstractThe Clinician-Administered PTSD Scale (CAPS) is used to measure posttraumatic stress symptoms (PTSS) and diagnose posttraumatic stress disorder (PTSD). However, its use, particularly in settings involving longitudinal assessment, has been complicated by changes in the diagnostic criteria between the fourth and fifth editions of theDiagnostic and Statistical Manual of Mental Disorders (i.e.,DSM-IV andDSM-5, respectively). The current sample included trauma-exposed U.S. veterans who were deployed in support of military operations following the September 11, 2001, terrorist attacks (N = 371) and were enrolled in a longitudinal study focused on deployment-related stress and traumatic brain injury. A hybrid clinical interview using item wording from the CAPS forDSM-IV (CAPS-IV) with the addition of items unique to the CAPS forDSM-5 (CAPS-5) was used to assess bothDSM-IV andDSM-5 PTSD diagnostic criteria, allowing for the calculation of separate total scores and diagnoses. Diagnostic agreement, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and interrater reliability between CAPS-IV and CAPS-5 were evaluated for the entire sample and stratified by gender. We found high diagnostic agreement (92.9% –95.4%), sensitivity (94.4%–98.2%), specificity (91.7%–92.8%), PPV (89.5%–93.0%), NPV (95.7%–98.1%), and interrater reliability,κ = 0.86–0.91,) for both men and women. The current study supports the use of a hybrid PTSD ...
