The CPSS is a 26-item self-report measure that assesses PTSD diagnostic criteria and symptom severity in children ages 8 to 18. It includes 2 event items, 17 symptom items, and 7 functional impairment items. Symptom items are rated on a 4-point frequency scale (0 = "not at all" to 3 = "5 or more times a week"). Functional impairment items are scored as 0 = "absent" or 1 = "present". The CPSS yields a total symptom severity scale score (ranging from 0 to 51) and a total severity-of-impairment score (ranging from 0 to 7). Scores can also be calculated for each of the three PTSD symptom clusters (i.e., B, C, and D).
The following are a few of the symptom items for this scale:
Circle the number that describes how often that problem has bothered you in the past month: Feeling upset when you think about it or hear about the event (for example, feeling scared, angry, sad, guilty, etc.).
(Areas of functioning items): Have the above problems gotten in the way of ... Relationships with your family (yes/no).
The CPSS is a child version of the Posttraumatic Diagnostic Scale (PDS; Foa et al., 1997). The language of the PDS was modified to incorporate developmentally appropriate language to maximize children's understanding of the items.
