This paper presents a comprehensive research agenda aimed at understanding the factors influencing young people's help-seeking behavior for mental health problems. The study, conducted in New South Wales, Queensland, and the ACT, involved 2721 young people aged 14-24 years and community gatekeepers. The research used both qualitative and quantitative methods, focusing on why young people, particularly young males, do not seek help when experiencing psychological distress or suicidal thoughts. It also explored how professional services can be made more accessible and appealing to young people, and the factors that facilitate or inhibit help-seeking. The help-seeking process was conceptualized as a transition from the personal domain of psychological distress to the interpersonal domain of seeking help. Key findings include patterns of help-seeking across adolescence and young adulthood, the relationship between help-seeking intentions and behavior, barriers such as lack of emotional competence and the help-negation effect, and facilitators like emotional competence and positive past experiences. The paper discusses the implications for developing interventions to encourage young people to seek help and identifies gaps in the existing literature, suggesting future research directions.This paper presents a comprehensive research agenda aimed at understanding the factors influencing young people's help-seeking behavior for mental health problems.
