This study compared the Children's Depression Inventory (CDI) scores of traumatized youth with or without PTSD to the scores of a nonclinical comparison group. Diagnostic interviews identified children with PTSD (28), traumatized PTSD negatives (64), and a nonclinical comparison group (41). In the absence of major comorbid disorders, the CDI scores of children and adolescents with PTSD significantly exceeded the CDI scores of traumatized PTSD negatives and controls on the CDI Total, Negative

... d, Ineffectiveness, and Anehdonia scales. The PTSD group also had significantly higher scores than the traumatized PTSD negatives on the Negative Self Esteem scale. Furthermore, as hypothesized, the CDI scores of the traumatized PTSD negatives and controls were not significantly different on any of the six subscales measured. On the other hand, there were three unexpected nonsignificant findings. First, the PTSD group mean CDI Interpersonal Problems score did not significantly differ from the traumatized PTSD negative group. Second, the PTSD group mean CDI Interpersonal Problems score also did not significantly differ from the control group. Finally, the PTSD group mean CDI Negative Self Esteem score did not significantly differ from the control group. Overall, PTSD was associated with increased depression across the majority of the CDI scales and trauma exposure without PTSD was not. Implications for research and practice are considered.
