The survey was organized by the Chinese University of Hong Kong and was one of the activities the Healthy Sleep School Campaign. TWGHs S.C.Gaw supported the program. Students and parents from F.1 to F.3 were asked to complete a packet of questionnaires on their sleep habits and sleep knowledge for baseline and follow-up evaluations, i.e., at the beginning of the second school term (Jan-Feb/2012), at the end of the second term (Jun/2012), at the beginning of another new academic year (Sep/2012) and at the end of first school term of that year (Jan-Feb/2013).

It was hoped that the project would benefit the school by promoting good sleep hygiene practice and enhancing understanding of sleep-related health problems among students, parents and teachers, and in the long run, would enhance physical and mental wellbeing among school-aged children and adolescents.
