Child PTSD Symptom Scale (CPSS) Popular
The Child PTSD Symptom Scale (CPSS) is a self-report measure designed to assess the severity of post-traumatic stress disorder among children and adolescents, ages 8 to 18 (Foa, Johnson, Feeny & Treadwell, 2001). The measure has a total of 24 items and includes two parts; the first has 17 items and measures the type and frequency of PTSD symptoms (mapping directly on to DSM-IV criteria), while the second has 7 items and measures the degree of functional impairment these symptoms cause.
This measure may be used by a trained practitioner as a diagnostic tool for PTSD (in the form of a semi-structured interview) or as a self-report measure. Clinicians and therapists should allow 20 minutes to administer the CPSS as an interview measure or 10 minutes for a respondent to complete it as a self-report measure. Both English and Spanish versions are available.
The CPSS is an adaptation of The PTSD Symptom Scale (PSS) (Foa, Riggs, Dancu, & Rothbaum, 1993), which has been used to assess symptom severity in US and non-US populations.
A total score for the 17 items corresponding to the DSM-IV criteria is rated on a scale from 0 to 3 (0=not at all; 1= once a week or less/once in a while; 2=2 to 4 times a week/half the time; and 3=5 or more times a week/almost always). Therefore, the range of the total score is 0 to 51. Higher scores indicating more severe symptoms. A clinical cutoff of 15 or greater is appropriate for diagnosing PTSD.
Scores for the functional impairment items (the last 7 questions) are scored dichotomously as absent (0) or present (1). Scores range from 0 -- 7, with higher scores indicating greater functional impairment.
