Given the high prevalence, chronicity and long-lasting health-related consequences of insomnia, together with the delay and limited help-seeking behavior, it calls the urgent need for early insomnia prevention and intervention in this vulnerable population.~Thus, this study aims to conduct a randomized controlled trial in comparing cognitive behavioral insomnia prevention program with the active control group in youths who are at risk of insomnia and to explore the effect of prevention program in preventing the incidence of insomnia problems.
