The aim of thisstudy is to assess General Practitioner (GP) trainees' training experience, and confidence in assessing and managing children and adolescents with common mental health conditions in primary care in Ireland. An online anonymous questionnaire was distributed to third and fourth year GP registrars enrolled in the Irish College of General Practitioners training schemes. The online questionnaire evaluated participants' training experiences and confidence levels in key areas of child and adolescent mental health in primary care. Sixty participants completed the survey out of 406, yielding a response rate of 14.8%. The majority (88%) reported no formal training or experience working in Child and Adolescent Mental Healthcare Services (CAMHS) during their GP training scheme. Responses indicated that many participants rated their competency, skills, and knowledge in essential areas of Child and Adolescent Mental Health as needing improvement. Similarly, their awareness of referral pathways and specialty services was below expectations, with poor perceived access to services. A large proportion (91.7%) expressed a definite need for further training in child and adolescent mental health disorders. The results highlight the need for enhanced training and support for GP trainees in the field of Child and Adolescent Mental Health, ensuring their ability to effectively and confidently address these common issues in primary care.
