Background: People’s participation in solving their own health problems is needed to be promoted. The oral health promotion
model development (youth’s health alliances) was expected to promote oral health awareness and increase public’s consciousness.
Objective: To develop the model for youth’s participation toward oral health promotion and to evaluate the model’s effectiveness on creating cleft lip-cleft palate perception.
Material and Method: This research had 3 steps, including situation analysis, developing the model and testing the model.
In the 1st step, a survey was conducted with 1,192 students. During the 2nd step, an action research was conducted with 103
volunteers, resulting in the CHANYA model. For the final step, an experiment was applied to 53 out of 103 volunteers. The data were analyzed with descriptive statistics and inferential statistic using paired t-test.
Results: The model promoted youths’ participation in the high to highest range and prepared oral health messages through
drama at the high to highest range. The model’s effectiveness in creating cleft lip-cleft palate perception was statistically
significant (p<0.05).
Conclusion: The CHANYA model was developed for supporting youth participation toward oral health promotion and the
model was effective in creating cleft lip- cleft palate perception. Moreover, the model could increase self-esteem, congruence,
self-awareness, thoughtful and collaboration within their team.
