Methods: Participants learned the symptoms of mental health issues among children and adolescents in the context of post-trauma, provision of early intervention, and channel for professional supports. They also answered a packet of measurements of mental health literacy before and after the programme.

Results: The paired sample t-test showed that participants reported higher willingness to contact with people having mental health problems (t = 2.787, P = 0.008, Cohen's d = 0.394), less stereotypes toward mental illness (t = 4.603, P < 0.001, d = 0.651) and a better understanding of self-help strategies (t = 2.16, P = .036, d = 0.322) than baseline.
