This clustered randomised controlled trial evaluated the effectiveness of the intervention. Members of the Action for Children team delivered training on The Guide Cymru to teachers, who then delivered the content to a cohort of Year 9 pupils aged between 13 and 14 in secondary schools across Wales. We aimed to administer the Guide Cymru to a younger age group (13–14 years) compared to Milin et al.’s [A recent review identified a lack of psychometrically sound mental health literacy scales for use in children and adolescents, which highlights a significant limitation in the current methods of child focused mental health literacy and evaluation of programmes [We hypothesised that children that received the Guide Cymru would show greater mental health literacy as indicated by: (1) greater knowledge of mental health and mental health problems, (2) reduced stigma towards people with mental health problems, (3) reduced levels of self-stigma, (4) a greater intention to seek help if they have a mental health problem, and (5) better mental health-related behaviours.
