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.

Conditions

Attitudes Towards Tobacco Industry

Outcome Measures

Primary Outcomes (1)

• Attitudes towards tobacco industry in children

  Children will report their opinions towards 4 statements: 1); Tobacco companies are a trustworthy industry; 2) Tobacco industries use many tactics to resist tobacco control regulations; 3) Tobacco industries do everything they can to get young people to smoke; 4) Tobacco industries cheated the public for commercial gain. All the 4 questions have 5 options from definitely yes to definitely no. The options will be recoded into 0-4 or 4-0, as appropriate, with higher scores indicating more negative attitudes towards the industry. A sum of scores from the 4 questions will be deemed as measurement of attitudes towards tobacco industry in primary school students.
