Data were collected from 5 Dutch high schools
as part of the Utrecht Healthy School (UHS) study
(N = 2425),22 the UHS pilot study school and its 4
sister schools from the UHS itself.These schools
were part of a convenience sample of schools that
were recruited for the UHS. All 5 schools participated
out of intrinsic motivation and were not
provided with funds or other incentives to participate.
All were all assisted with the questionnaire
procedures by the research team. All are situated
in suburban areas of middle-to-large cities in the
Netherlands. Therefore, all 5 schools should be
categorized as in-between rural and urban.
