ADHD is the most frequent reason for attendance at Child and Adolescent Mental Health Services (CAMHS). General practitioners (GPs) play a key role in recognising symptoms, referring for assessment and supporting ongoing treatment. However, there is an ambiguous understanding of ADHD among GPs, and different attitudes regarding the validity of ADHD as a construct. The present study aims to explore and identify GPs attitudes and beliefs about ADHD in the Irish context, and to find out the association of those attitudes with other factors.
