The study investigated whether religiosity mediates or moderates the relationship between war atrocities and inattention-hyperactivity in children from Gaza Strip and South Lebanon. Participants were 600 children aged 12-16 years, of whom 273 were males and 327 were females from public schools. Questionnaires were administered by two psychologists. To examine the mediating and moderating effects of religiosity, Baron and Kenney's mediational criteria and hierarchal regression analysis were conducted. Results indicated that religiosity mediated and moderated the relationship between war atrocities and inattention-hyperactivity in children. The clinical and research implications of these conclusions are discussed.
