A randomized controlled intervention program trial was carried out in 14 females' schools in East Jerusalem, selected randomly by a stratified sampling of four groups of schools. The primary target population was the students, while the secondary target populations were the mothers and the teachers at these schools. From the schools operating in East Jerusalem (Palestinian Authority, Jerusalem Municipality, private, and United Nations Relief and Works Agency) grades 4 and 5 were considered eligible to participate in the pre- and post-intervention studies.
