Attitudes Towards Tobacco Industry

Brief summary

The brief RCT will be conducted in the form of a questionnaire survey, with two kinds of leaflets embedded in the same questionnaire. The RCT will be conducted in classrooms by teachers who will be given two kinds of questionnaires (with leaflet embedded) used for intervention and control groups. The questionnaires will be mixed in a way that two adjacent questionnaires are always different. The intervention leaflets will contain information for tobacco industry denormalisation. The control leaflets will contain information for tobacco control policy in Hong Kong. The study aims to test the effect of a leaflet-based intervention on primary school students' attitudes towards tobacco industry.
