  1. Values are numbers; (percentage by column), (percentage by row)
  2. aData from New Zealand Ministry of Education (Ministry of Education 2012), based on schools in the Auckland region comprising years 7–13, 9–13, 7–10, or 11–13
  3. bParents were encouraged to make the consent decision in consultation with their children. Where parents gave consent for children to participate, 96% of adolescents gave assent
  4. cSES categorization for New Zealand schools is based on the SES of families within the school’s catchment area, calculated from census data relating to household income, educational qualifications, and occupation of adults within the household, household crowding, and income support provided to the household. Decile 10 includes the 10% of schools with the lowest proportion of low SES families within the catchment. Decile 1 includes the 10% of schools with the highest proportion of low SES families within the catchment (Ministry of Education, 2017)
