Treatment of Posttraumatic Stress Disorder in Postwar Kosovar Adolescents Using Mind-Body Skills Groups: A Randomized Controlled Trial. Journal of Clinical Psychiatry, 2008 Sep;69 (9):1469-76.

This study demonstrates that CMBM’s groundbreaking model can be used to produce highly significant and lasting changes in levels of posttraumatic stress symptoms in highly traumatized children.

82 high school students in Kosovo participated in this randomized-controlled study. The program was conducted by teachers in an educational, supportive small group setting and included meditation, guided imagery, breathing techniques, and biofeedback as well as self-expression through words, drawings, and movement. All the students met the criteria for posttraumatic stress disorder (PTSD) which was measured using the Harvard Trauma Questionnaire. Following the program, the number of students having symptoms indicating PTSD was significantly reduced from 100% to 18%. The reduction in symptoms was maintained at a 3 month follow-up.
