Summary

This project aims to evaluate the relative efficacy of a peer-led intervention based on the Social Cognitive Theory and Health Belief Model versus the control (only pamphlet delivery) on increasing the prevalence of healthy oral behaviors and oral health status among adolescents in Hong Kong. A two-arm non-blinded randomized controlled trial will be conducted among random samples of adolescents enrolling in secondary schools in Hong Kong. In addition to a baseline survey, two follow-up evaluative surveys will be conducted at months 6 and 12. Survey questionnaires will be conducted to participants at three time points (baseline, 6-, 12-month follow-up). Dental check-up examinations will be evaluated at two time points (baseline, 6-month follow-up). Repeated measures will be used to record participants' background, oral behaviors, theory based cognition, and potential confounders. Validated scales will be used. DMFT, plaque index and CPI index will be used to assess the oral health status of participants.

Interventions

BEHAVIORAL

peer-led theory-based intervention group

We plan to select 2-8 peer leaders in S2 students within each school in the intervention group. A total of 25-48 peer leaders will be selected and trained in this study. An experienced behavioural scientist will train the peer leaders through lectures, workshops, and individual counselling. A total of 6 hours training (3 hours per day x 2 days) will be conducted during weekends. Peer leaders will practice in groups, and only those who pass the evaluation are allowed to conduct peer-led interventions. We will record the performance and give specific feedback to each peer leader.
