The brief intervention comprised the main intervention (tobacco industry denormalisation \[TID\] video, TID worksheet and sugar-sweetened beverages \[SSB\] worksheet) and booster intervention (worksheets where key contents in the main intervention reappeared). The worksheets in the main intervention were printed in colour and contained eight pictures and eight texts which described the pictures. Students needed to match the pictures and texts. The booster worksheets contained the previous eight coloured pictures for the TID and SSB worksheet groups or six coloured screenshots from the TID video. Students needed to complete the six true or false questions based on the pictures provided.
