Child Posttraumatic Stress Reaction Index (CPTS-RI)

 

Child Posttraumatic Stress Reaction Index (CPTS-RI)

Frederick, Pynoos, & Nader, 1992

Description

The CPTS-RI (also known as the Reaction Index) is a 20-item interviewer-administered scale for children between ages 6 and 17 that assesses some of the DSM-III-R/DSM-IV symptoms for PTSD as well as guilt, impulse control, somatic symptoms, and regressive behaviors. Items are rated on a five point frequency scale (ranging from "none" to "most of the time"). The CPTS-RI yields total scores ranging from 0 to 80 that reflect the frequency of symptoms. Categories of degree of disorder (from doubtful to very severe) can be assigned based on the total scale score. This interview is available in a child’s and a parent’s report version.

Sample Item

Do you ever get scared, afraid, or upset when you think about (event)?

Versions

The UCLA PTSD Index for DSM-IV (UPID) (Pynoos, et al., 1998) is a revision of the 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).

The CPTS-RI Revision 2 (also referred to as the PTSD Index for DSM-IV; Rodriguez, 2002) is also a revision of the CPTS-RI. It was designed to increase the sensitivity of screening of trauma exposure and criterion A1 and A2 and to provide more guidance for the interviewer and child throughout the interview.
