CPSS is used to measure PTSD diagnosis and severity in the past month in youth. It contains a trauma screening as well as a 27-item semi-structured interview that includes questions assessing DSM-5 PTSD symptoms as well as questions assessing impairment of endorsed symptoms on daily functioning. The screener takes about 10 minutes to complete and asks about intrusion, avoidance, changes in cognition and mood, and increased reactivity.
