Official Title: Promoting Alcohol-related Attitudinal and Behavioural Change Amongst Adolescents Through Internet Intervention: A Cluster Randomised Controlled Trial
Brief Summary:
Objectives The aims of this study are to test the effectiveness of an online quiz competition in changing adolescents' alcohol-related attitudes and behaviour and to explore the fe¬asibility of using Internet viral marketing to reach a significant number of adolescents.
Hypotheses to be tested
- The present online quiz competition is more effective in changing adolescents' alcohol-related attitudes and behaviours than traditional health promotion.
- Internet viral marketing is effective in reaching a significant number of adolescents.
Design and subjects The study will constitute a cluster randomised controlled trial for 20 secondary schools (6,720 Grade 7 to 9 students). Schools will be randomised to intervention or control arm with equal likelihood. Students in intervention schools will be invited to take part in the Internet campaign whereas those in control schools will receive relevant promotional leaflets.
Study instrument An alcohol attitude and behaviour survey will be compiled with reference to standardised, validated instruments.
Intervention Participants will log into the website and answer alcohol-related multiple-choice questions. They will be encouraged to promulgate the campaign to others.
Main outcome measures Alcohol-related attitude and behaviour will be the primary outcome measures.
Data analysis Multilevel regressions will mainly be used to evaluate the difference in attitude and behaviour.
Expected results The results of the proposed
Detailed Summary:
Intervention Arm: Internet Quiz Competition Campaign
The intervention is designed based on the Theory of Planned Behavior. Participants will gain alcohol-related knowledge through the participation of the intervention, which would in turn alter their attitude concerning drinking and alcohol use. According to the Theory of Planned Behavior, such knowledge and attitude improvement would reduce participants' intention to drink and thus change or prevent their drinking behavior [21]. To promote the intervention, we will conduct a briefing session and a demonstration session for all eligible students in participating schools in the intervention arm. Campaign promotion brochures and posters will be distributed within those schools.
Campaign Design
Participants of the campaign will receive a referral code from those who refer them to the online quiz website; starters of the campaigns will receive the code directly from the research team. These referral codes, sets of 8-digit numbers, will be unique to each user and used to track the referral process. During registration, participants will be asked to provide basic demographic information and their referral code. After registration, their baseline attitudes and behavior will be assessed using the Alcohol Attitudes and Behavior survey.
The campaign will last for 30 days, starting from the day of the school promotion session. The aim of the competition from the participants' perspective will be to obtain the highest score possible to win a prize. They will have two ways of doing so.
The first way will be to answer the online quiz questions. The po-ints gained in this way will constitute the "answer score." Alcohol-related mul
