Mind-body Skills Groups for War-Related Trauma in Adolescents in Gaza

The goal of this clinical trial is to learn if mind-body skills groups can reduce posttraumatic stress disorder and emotional and behavioral problems in war-traumatized adolescents in Gaza. The main questions it aims to answer are: * Do mind-body skills groups reduce posttraumatic stress disorder symptoms in war-traumatized adolescents in Gaza? * Do mind-body skills groups reduce emotional and behavioral problems in war-traumatized adolescents in Gaza? Researchers will compare the results of adolescents who do not attend mind-body skills groups to adolescents who attend mind-body skills groups see if those who attend groups have less posttraumatic stress disorder symptoms and emotional and behavioral problems. Participants will: * Be screened to determine whether they qualify to be in the study * If they qualify, they will attend 5 mind-body skills group sessions (if they are not in the control group) * Fill out research packets before the first session, after the last session, and at 2-month follow-up.
