A considerable amount of research has been conducted since posttraumat
ic stress disorder (PTSD) was included in the American Psychiatric Ass
ociation's taxonomy of mental disorders. Despite this rapidly expandin
g literature base, it must be acknowledged that the majority of these
studies have involved traumatized adults. It is of interest to observe
however that child-clinical investigators have made a number of theor
etical and applied contributions involving the treatment of traumatize
d youth. Whereas different treatment modalities have been applied with
differential degrees of efficacy with traumatized youth, this article
considers exposure-based interventions that have evinced efficacy ove
r time. Adult studies are also reviewed as the child-adolescent litera
ture has drawn from the adult literature and as comparatively fewer in
vestigations have been conducted with traumatized youth.
