Ethics approval and consent to participate
: University of the Highlands and Islands Research and Ethical Committee approved the study (REF: OLETHSHE1004). The committee approved the parent/legal carer opt-out consent procedures. Written consent was given by all student participants. The consent procedure was as follows: Once a school had consented to participate, the named parent/carer on the school register was sent a study information pack, which included a form to be returned to the school if they wished to opt their child out of the study. The parent/carer was given the opportunity to contact the research team to discuss the study by telephone or email. Students who were not opted out by a parent/carer were given their study information sheet and consent form in the classroom. Students who had been opted out of the study were given education assignments to do while their classmates completed the questionnaires.
