Berger, R., Gelkopf, M., and Heineberg, Y. (2012). A Teacher-Delivered Intervention for Adolescents Exposed to Ongoing and Intense Traumatic War-Related Stress: A Quasi-Randomized Controlled Study. (Abstract only.) Journal of Adolescent Health. 51(5): 453-461.
The authors of this study evaluate posttraumatic symptomatology in a sample of seventh- and eighth-grade students from Sderot, a town in Israel which faces near-constant threat of shelling and mortar attacks. They found efficacy of a teacher-delivered intervention in preventing and reducing adolescents' related symptoms. This may have applications for children that are displaced or exposed to continued ongoing stressors.
