This 30-item semi-structured interview provides a dimensional and categorical measure of PTSD. The severity score is based on frequency and intensity of PTSD symptoms. Categorically, it determines presence of both lifetime and current PTSD. Current and lifetime PTSD will be assessed at pre-treatment. Only current PTSD will be assessed at post-treatment. This interview also assesses the onset and duration of symptoms, distress, impact of symptoms on functioning (social and occupational), change in symptoms since a previous administration, response validity, and dissociative subtype of PTSD. Total score ranging from 0 to 80, with higher scores indicating greater severity of PTSD symptoms.
