| Annotation | The diagnostic validity of the Post-Traumatic Stress Disorder Checklist (PCL) was determined against the "gold standard" of the Clinician Administered PTSD Scale (CAPS) in a clinical sample of 100 UK older people aged 65+ being treated for medical and/or psychiatric conditions in a hospital setting. Participants completed the PCL measures of mood, cognition, physical health, alcohol use and the CAPS. A receiver operating characteristics curve was constructed to determine the optimal cut-point of the PCL. Analysis of variance was used to examine clinical differences between PTSD cases, sub-threshold cases and the remainder of the sample. Using the recommended cut-point of 50, the PCL had a sensitivity of 9.40, specificity of 0.97 and positive predictive value of 0.57. However, these values changed to 0.90, 0.87 and 0.45 respectively when the optimal cut-point of 36 was used. With an adjusted cut-point, the PCL is an acceptable brief screening instrument for PTSD in older people. (RH). |
