title: Psychometric properties of Darryl, a cartoon based measure to assess community violence-related PTSD in children.
abstract: OBJECTIVE
  To examine the reliability and validity of Darryl, a cartoon-based measure of PTSD symptoms and a screening tool for identifying children and adolescents with a PTSD diagnosis.
  
  
  METHODS
  Exposure to community violence, PTSD symptoms and diagnostic status were assessed in a sample of 49 children and adolescents at an urban outpatient psychiatry clinic.
  
  
  RESULTS
  Darryl has good internal consistency for the full scale and adequate reliability for each DSM-IV PTSD symptom cluster. Darryl correlates significantly (r = 0.64, P < 0.001) with the most frequently used measure for assessing PTSD in children (CPTSD-RI). As a screening tool, Darryl has excellent sensitivity and specificity in relationship to the KID-SCID.
  
  
  CONCLUSIONS
  In comparison to other child PTSD measures, Darryl has comparable or better psychometric properties and assesses PTSD symptoms in a more developmentally appropriate manner, especially in the domain of community violence. The value of Darryl as a screening tool remains preliminary given the limited number of diagnosed cases of PTSD in the study sample. Full scale efforts at replication are warranted.
