PTSD Rating Scales: Two rating scales can be used by clinicians to help identify children's or adolescents' exposure to child abuse, interpersonal violence and other traumatic events, to identify PTSD symptoms, and to monitor symptoms. These are the UCLA PTSD Reaction Index (RI) and the Child PTSD Symptom Scale (CPSS). The RI is rated separately by the child or adolescent and a parent; the CPSS is rated only by the child or adolescent. This is the Child PTSD Symptom Scale. | Accessed online February 2019
