Psychiatric comorbidity in childhood post traumatic stress disorder.
OBJECTIVE
The purpose of this study was to examine the psychiatric comorbidity between children presenting with Post Traumatic Stress Disorder (PTSD) and traumatized children not developing this disorder.


METHODS
One-hundred and seventeen severely maltreated children were examined for evidence of PTSD. Analyses probed for diagnostic relationship, between PTSD and other formal diagnoses on The Diagnostic Interview for Children and Adolescents, Revised Version (DICA-CR).


METHODS
All children presented before a juvenile/family court due to severe child maltreatment and psychological trauma. These children had been ordered removed from parental custody due to the trauma suffered by the child. For the purposes of analyses, this entire group of maltreated and traumatized children were dichotomized into a PTSD group and a non-PTSD group. Thirty-five percent (41 of 117) of the children met strict DICA criteria for PTSD.


METHODS
The children were examined by means of a structured clinical interview. The Diagnostic Interview for Children and Adolescents, revised version (DICA-Child-R), along with a more general psychiatric interview. The DICA-Child-R responses provided the only determination of whether the children met formal PTSD criteria. Data gathering on the sample also included a comprehensive review of risk factors for the development of PTSD, including demographics, and type(s) of trauma suffered.


RESULTS
Findings revealed that the PTSD diagnosis was significantly correlated with: 1. Attention Deficit Hyperactivity Disorder (ADHD) 2. Other anxiety disorders 3. Brief Psychotic Disorder or Psychotic Disorder NOS 4. The presence of suicidal ideation 5. A trend toward mood disorders. There were no differences between the two samples on measures of age, race, and family income.


CONCLUSIONS
Pediatric PTSD is a severe psychiatric disorder. In this study, PTSD was statistically related to other formal psychiatric diagnoses. The investigators attended to the issues relating to true comorbidity versus inaccurate diagnosis secondary to symptom overlap between different conditions. Applying strict criteria, the results suggest that the presence of PTSD in children confers a substantial likelihood of other formal diagnosis. Moreover, the symptom of suicidal ideation was overrepresented among PTSD subjects. Given these additional conditions, more extensive evaluation and specialized, multi-modal treatment should be considered in children presenting with PTSD.
