All study participants were assessed using the Clinician-Administered PTSD Scale (CAPS) (Blake et al., 1990; Blake et al., 1995)—a structured diagnostic interview that assesses the frequency and severity of the 17 DSM-IV PTSD symptoms, along with associated features of the disorder, and degree of functional impairment. Lifetime PTSD diagnosis inter-rater reliability was excellent (kappa=0.87).
