Description:

The study involves a behavioural intervention with social norms approaches to correct smoking misperceptions, reduce smoking susceptibility and change smoking-related behaviours in Hong Kong adolescents. A 2-arm stratified clustered randomised controlled trial (RCT) will be conducted to evaluate the effectiveness of the intervention. A total of 18 secondary schools will be randomly selected from the 5 regions in Hong Kong and invited to the RCT. The schools will then be randomly allocated to intervention or control group in the ratio of 1:1. Secondary 1 to 5 (US Grade 7 to 11) students will be invited. Students in both intervention and control group will complete a baseline survey, and the intervention group will receive the intervention after the baseline.
