A Modified Pilot Randomised Controlled Trial (RCT) on the Effectiveness of an Online Quiz Game to Promote Tobacco-Related Knowledge, Attitudes, and Behaviours Among Primary School Students

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 8-12th days

Students reported their opinions towards 5 statements in pre and post tests: \[Pre-test\] 1) Smoking causes wrinkles to form on the skin; 2) Third-hand smoke can remain on surfaces for weeks; 3) E-cigarettes can help with smoking cessation; 4) Tobacco companies aim to prevent teenagers from smoking; 5) The Hong Kong government has already banned the sale of e-cigarettes. \[Post-test\] 1) Smoking can cause hair loss; 2) Opening windows or turning on a fan can eliminate the effects of thirdhand smoke; 3) E-cigarettes avoid the problem of secondhand smoke; 4) Tobacco companies hire influencers to promote tobacco products; 5) The Hong Kong government has already banned the sale of heated tobacco products. Students' knowledge 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 better knowledge.

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 8-12th days.

Students will report their opinions towards 5 statements: 1) Smoking is a selfish behavior; 2) I hope to avoid exposure to secondhand smoke; 3) Vaping is a trend.; 4) Tobacco companies use different methods to attract people to smoke; 5) The government should prohibit people from smoking while walking. 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.

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 8-12th 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.
