The purpose of this study was to investigate a psychological model on young people’s help-seeking behaviours. A quantitative cross sectional design was utilised. A sample of 185 adolescents (M=93, F=92) from one secondary school in Leinster was used (age range 13-17 years). Self-reported questionnaires were used to explore gender differences and the effect of young people’s knowledge and understanding of mental health, their resilience, self-esteem and general health on help-seeking behaviours. Self-esteem was explored as a ‘moderator’ between knowledge and understanding of mental health, resilience and help-seeking behaviours. Data was collected, analysed and generated using multiple regression, partial correlations and an independent t-test. Analysis revealed the model to be significant. Self-esteem was identified as a significant moderator between knowledge and understanding of mental health and help-seeking behaviours, and resilience and help-seeking behaviours. No gender differences were identified. A clear absence of awareness was found among young people regarding youth mental health services available to them, suggesting the services are not being used. Potential reasons as to why young people are and would not seek help were identified which include pride, lower or lack of self-esteem, shame and self-helping.
