Child PTSD Symptom Scale
Child PTSD Symptom Scale (CPSS) · Also known as: CPSS, CPSS-5, CPSS-IV
The Child PTSD Symptom Scale (CPSS), developed by Edna Foa and colleagues in 2001, is a child-report assessment of posttraumatic stress disorder (PTSD) symptoms in children and adolescents aged 8–18 years following traumatic exposure. The CPSS measures the three core symptom clusters of PTSD (re-experiencing, avoidance, hyperarousal) aligned with DSM-5 diagnostic criteria, making it a valuable screening and outcome measurement tool in trauma-focused clinical practice and research.

When to use it
The CPSS is recommended for children and adolescents aged 8–18 years exposed to traumatic events (abuse, violence, accidents, disasters, loss) presenting with trauma-related concerns in pediatric, mental health, school, and trauma-informed care settings. It is particularly valuable as an outcome measure in trauma-focused cognitive-behavioral therapy and other evidence-based trauma treatments. Less appropriate for children under 8 years or those with severe cognitive/communication impairment affecting report validity.
Strengths & limitations
- Directly assesses DSM-5 PTSD symptom criteria, aligning with current diagnostic standards.
- Child-report format captures subjective trauma symptom experience distinct from parent observation.
- Sensitive to change, making it valuable for outcome measurement in trauma treatment trials.
- Brief (31 items) and straightforward scoring, practical for busy trauma-informed clinics.
- Parent version (CPSS-Parent) enables multi-informant assessment complementing child report.
- Strong psychometric properties with sensitivity and specificity for PTSD ranging 75–90%.
- Screening and outcome tool, not diagnostic; elevated scores suggest PTSD but require comprehensive clinical interview for diagnosis.
- Child self-report subject to minimization of symptoms (shame, guilt) or exaggeration (attention-seeking) affecting validity.
- Parent-report discrepancies common; some children conceal trauma symptoms from caregivers.
- Limited normative data in non-English-speaking populations; translations available but cultural adaptation varies.
- Does not assess trauma-related dissociation, complex trauma sequelae, or developmental changes in PTSD presentation.
Frequently asked
Can the CPSS diagnose PTSD?
No. The CPSS screens for PTSD symptoms and is valuable for outcome measurement, but diagnosis requires comprehensive clinical interview, trauma history assessment, and evaluation of functional impairment. CPSS scores above 31 suggest probable PTSD and warrant specialist evaluation.
What is the difference between CPSS and CPSS-5?
The original CPSS (2001) followed DSM-IV criteria. The CPSS-5 (2016) was revised to align with DSM-5 changes, expanding symptom categories to better capture modern PTSD conceptualization. Use CPSS-5 for current assessments; older CPSS norms are less relevant.
Should I use child self-report or parent report?
Collect both when possible. Children often report more PTSD symptoms than parents due to internal experiences (intrusive thoughts, nightmares) not visible to caregivers. However, parents may observe behavioral changes (avoidance, irritability). Integrate perspectives rather than relying on one informant.
How do I administer the CPSS if the child has not disclosed trauma?
Do not administer the CPSS unless trauma exposure is known or suspected and discussed. If trauma is suspected but not disclosed, consult with caregivers, use gentle inquiry, and consider trauma-informed screening approaches before administering the full scale.
