Youth traumatized by natural disasters report high levels of posttraumatic stress such as symptoms of posttraumatic stress disorder, other anxiety disorders, and depression. Research suggests that cognitive behavioral therapies are promising interventions for symptom reduction; however, few cognitive behavioral treatments have been systematically tested in youth hurricane survivors. The current study provides an examination of the efficacy of an intervention manual designed specifically for hurricane-exposed youth (i.e., the "StArT" manual) using a partially nonconcurrent multiple baseline design. Youth ages 8-13 (n=6) who met diagnostic criteria for posttraumatic stress disorder were provided the individual "StArT" treatment in their school. Youth were assessed at pretreatment, weekly during treatment, and at posttreatment. Results provide initial evidence for the efficacy of the "StArT" manual and suggest the feasibility of conducting the "StArT" manual in a school setting. The importance of large-scale tests of effectiveness and implementation of cognitive behavioral treatments in the wake of disaster among youth are discussed. (Contains 2 tables and 1 figure.)
