The objective of this study is to determine whether participation in a group program incorporating mind-body techniques decreases symptoms of posttraumatic stress in adolescents. Students will be screened for posttraumatic stress using the Harvard Trauma Questionnaire and eighty-two qualifying students will be randomly assigned to a 12-session mind-body group program or a wait-list delayed intervention group. The program will be conducted by the teachers at a high school in Kosovo and include meditation, biofeedback, drawings, autogenic training, genograms, and a variety of movement and breathing techniques. Changes in posttraumatic stress symptoms will be measured using the Harvard Trauma Questionnaire.
