This research project is conducted jointly with academics from Tokyo University -Japan. We are investigating how health literacy is understood locally; then developing a health literacy instrument in line with findings obtained from the ground up. The project also entails conducting a cross sectional study among adolescents 12-15 years old in the Ramallah District of the West Bank, using an internationally validated health literacy instrument developed specifically for adolescents and the locally developed one, then comparing their psychometric properties and determining the prevalence of health literacy and its associated factors in the Ramallah District.
