简要总结
The goal of this pilot RCT is to evaluate the effectiveness of comics containing tobacco-related content in improving tobacco-related knowledge and attitudes among Hong Kong primary school students. The main questions it aims to answer are:
- Is the intervention (i.e. comics) effective in improving tobacco-related knowledge (including alternative smoking products (ASPs) and tobacco control development in the world and Hong Kong) compared to controls (i.e. information sheets)?
- Is the intervention (i.e.comics) effective in improving tobacco-related attitudes and intentions (including ASPs and tobacco control development in the world and Hong Kong) compared to controls (i.e. information sheets)?
Researchers will compare the questionnaire results from students to see if intervention groups (students reading comics) will have better tobacco-related knowledge, higher anti-tobacco attitudes and lower intention to smoke compared to the control group (students reading information sheets).

研究组 & 干预措施
Intervention
Intervention group students will receive a series of five tobacco-related comics during the 2-week study period.
干预措施: Tobacco-related comics (Other)
Control
Control group students will receive five conventional health leaflets or related educational materials.
干预措施: Conventional health leaflet (Other)
结局指标
主要结局
Effectiveness of intervention on tobacco-related intentions (including ASPs and tobacco control development in the world and Hong Kong)
时间窗: Right before the intervention and at 12-16th days.
Students were asked: If one of your good friends offers you a traditional cigarette, e-cigarette or heated tobacco product, ask you to have a few puffs, and no one will know about this as no more smoking in the future. Will you use them? Students' intention will be assessed using a 5-point Likert scale, with each item rated on a 5-point Likert scale ranging from 1 (Definitely no) to 5 (Definitely yes). Lower scores indicate a lower intention to use ASPs.
Effectiveness of intervention on tobacco-related knowledge (including ASPs and tobacco control development in the world and Hong Kong)
时间窗: Right before the intervention and at 12-16th days
Students reported their opinions towards 5 statements in both pre-test and post-test: 1\) Smoking accelerates skin ageing; 2) Secondhand smoke can trigger asthma and middle ear infections in children; 3) Opening windows or using a fan can eliminate the effects of thirdhand smoke; 4) E-cigarettes with added flavors are harmless to the body; 5) Hong Kong prohibits smoking while queuing for public transport. Questions may be subject to change, as they will be adjusted according to the leaflets/comics, while maintaining a similar format. Students' knowledge will be assessed using a 3-point Likert scale, with each item rated on a 3-point Likert scale ranging from -1 (wrong) to 1 (correct).
Effectiveness of intervention on tobacco-related attitudes (including ASPs and tobacco control development in the world and Hong Kong)
时间窗: Right before the intervention and at 12-16th days.
Students will report their opinions towards 5 statements: 1) Banning smoking in all places would harm smokers' rights; 2) I will actively avoid secondhand smoke; 3) Using e-cigarettes is safer than smoking traditional cigarettes; 4) Tobacco companies use various methods to encourage people to smoke; 5) The government should ban the sale of flavored smoking products. Questions may be subject to change, as they will be adjusted according to the leaflets/comics, while maintaining a similar format. Students' attitudes will be assessed using a 5-point Likert scale, with each item rated on a 5-point Likert scale ranging from 1 (Strongly disagree) to 5 (Strongly agree). Item scores will be recoded as appropriate, so that higher scores consistently reflect more negative attitudes.
次要结局
- Effectiveness of intervention on SHS and THS exposure at home(Right before the intervention and at 12-16th days.)
- Effectiveness of intervention on tobacco use(Right before the intervention and at 12-16th days.)
- Adherence to the 5-day intervention(At 12-16th days)
- Satisfaction of students towards intervention(At 12-16th days)
