Declarations
:
: Natsal-2 received ethical approval by the University College London and North Thames Multi-Centre Research Ethics Committees and all the Local Research Ethics Committees in Britain. Natsal-3 received ethical approval from the Oxford Research Ethics Committee A (reference number 10/H0604/27), including for the informed verbal consent procedures. Informed consent was obtained for all participants in all three rounds of the survey. For Natsal-1 participants, the survey and its purposes were fully explained to participants, and eligible respondents were given letters outlining the aims of the study and then invited to engage with the study. In the case of 16- and 17-year-old subjects, parental consent was sought before the young person was interviewed. For Natsal-2 participants, the survey and its purposes were fully explained to participants, and a leaflet was provided which described the study in some detail, explaining the confidentiality issues. If the selected person was aged 16 or 17 and living in the parental home, then the interviewer gave a parent information letter and agreement from one of the parents was also obtained. All Natsal-3 participants were given an information leaflet to read prior to participation, and verbal consent for study participation was obtained. All participants provided their own consent to participate, however for 16- and 17 -year-olds living at home, a parent/guardian provided additional verbal assent for participation. Methods for all surveys were carried out in accordance with relevant guidelines and regulations in the Declaration of Helsinki.
