Stress and vulnerability to posttraumatic stress disorder in children and adolescents

OBJECTIVE

This study examined the experiential factors and interacting vulnerabilities that contribute to the development of posttraumatic stress disorder (PTSD) in children and adolescents.

METHOD

Of 100 consecutive referrals to an inner-city child and adolescent psychiatry clinic, 59 had experienced a trauma that qualified as a precipitant of PTSD. For those with trauma, ages ranged from 3 to 18 years (mean=9.9, SD=4.10); 39 (66%) were males. The authors used a series of multiple regression analyses to examine the contribution of demographic characteristics, the nature of the stressor(s), and the role of preexisting clinical signs in the development of PTSD.

RESULTS

Twenty-two percent of the 59 children who had been traumatized met full criteria for PTSD, 32% had some symptoms of PTSD but did not meet full criteria, and 46% had no symptoms of PTSD. Witnessing domestic violence or being physically abused predicted severity of PTSD. Children with preexisting aggressive behavior were more likely to be victims of physical abuse.

CONCLUSIONS

Traumatic experience interacts with factors in the child and family to contribute to the development of PTSD. Trauma that threatens family integrity appears to make a strong contribution to the development of PTSD. Increased understanding of the factors contributing to PTSD may provide additional opportunities for developing effective interventions.
