Other Clinical Trial - A Cluster RCT on TID

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Clinical Trial Summary

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. Assessments were conducted immediately (T1), two weeks (T2), one month (T3) and three months (T4) after the main intervention.
