Diagnostic utility of CPSS vs. CAPS-CA for assessing posttraumatic stress symptoms in children and adolescents
Hukkelberg, S. S., Ormhaug, S. M., Holt, T., Wentzel-Larsen, T., & Jensen, T. K. (2014). Diagnostic utility of CPSS vs. CAPS-CA for assessing posttraumatic stress symptoms in children and adolescents. Journal of Anxiety Disorders, 28(1), 51-56. doi:10.1016/j.janxdis.2013.11.001
Objectives
This study compared the diagnostic utility of the symptom part of the child PTSD symptom scale (CPSS) screening instrument with the clinician-administered PTSD scale for children and adolescents (CAPS-CA).
Methods
The study included a clinical sample of traumatized children and adolescents (mean age 15.1, range 10–18) living in Norway, who were assessed for posttraumatic stress symptoms using the CPSS and the CAPS-CA. Diagnostic utility was investigated using receiver operating characteristic analyses.
Results
The results showed that CPSS reached medium effect sizes (AUC from .63 to .76). The sensitivity was good (.80), but the specificity was relatively low (.56). Kappa between CPSS and CAPS-CA was low (? = .27).
Conclusions
Findings suggests that CPSS is a good tool for screening purposes, but not as a diagnostic instrument in an early phase of assessment. Implications and limitations of the findings are discussed.
