Evaluation of the Child and Family Traumatic Stress Intervention

A randomized controlled trial of this brief secondary prevention model for intervening with children and families exposed to violence and trauma was completed in 2009. 106 youth were randomly assigned to the Intervention (n = 53) or a four‐session supportive Comparison condition (N = 53). At baseline, youth in both groups had similar demographics, including thCFe nature of their past traumatic experiences, the number of past trauma exposures, and symptom severity. 

The traumatic events that brought participants to the study were: 

  • 24% motor vehicle accident (MVA) 
  • 18% sexual abuse 
  • 19% witnessing violence 
  • 21% physical assaults
  • 8% injuries (e.g., sports, cycling) 
  • 5% animal bite 
  • 5% threats of violence (e.g., mugging)

At follow‐up, the Intervention group demonstrated significantly fewer full and partial PTSD diagnoses than the Comparison group on a standardized diagnostic measure of PTSD. Full results are published in the Journal of Child Psychiatry and Psychology.
