Development of anxiety disorders in a traumatized pediatric population: a preliminary longitudinal evaluation.

OBJECTIVE

The current study was conducted to determine if post-traumatic stress disorder (PTSD) symptomatology predicted later development of non-PTSD anxiety disorders in children and adolescents victimized by interpersonal trauma.

METHODS

Thirty-four children with a history of interpersonal trauma and no initial diagnosis of anxiety disorder participated in the study. Children were assessed at time one (T1) and then 12-18 months later at time two (T2). At T1, the Clinician Administered PTSD Scale for Children and Adolescents (CAPS-CA) and the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL) were used to evaluate children's PTSD symptoms and comorbid non-PTSD anxiety disorder diagnosis. At T2, the CAPS-CA and the K-SADS-PL were repeated.

RESULTS

The diagnosis of PTSD and PTSD symptoms in children exposed to interpersonal trauma at T1, particularly the symptoms associated with avoidance and constricted emotional expression (criteria C) as well as physiological hyperarousal (criteria D), predicted the development of other anxiety disorders at T2.

CONCLUSION

Traumatized children with initial PTSD symptomatology may be at risk of later development of other anxiety disorders.
