The UCLA PTSD Index for DSM-IV (UPID) (Pynoos, et al., 1998) is a revision of the Child PTSD Reaction Index: CPTS-RI. It is a 48-item semi-structured interview that assesses a child's exposure to 26 types of traumatic events and assesses DSM-IV PTSD diagnostic criteria. It includes 19 items to assess the 17 symptoms of PTSD as well as 2 associated symptoms (guilt and fear of event's recurring).
