The main author and two trained research assistants did the
data collection. Prior to the survey, the questionnaire was
pilot tested on a young volunteer and areas of difficulties
were modified. In all the schools, the questionnaires were
completed by the students in their classrooms and by the
teachers in their staff rooms. It was clearly stated on all the
questionnaires that participants’ responses would remain
anonymous. Participation was voluntary and participants
were free to withdraw at any stage without any unpleasant
consequences.
