Assessing ADHD symptoms in clinical public practice: Is a reliable final diagnosis possible?

Longitudinal descriptive study of two clinical cohorts (n=134) in primary care (2004, 2009) analyzing ADHD evaluation processes and variables associated with final diagnosis. Found low inter-professional reliability (kappa=0.39) and diagnostic variations according to professional (PC, neuropediatrician, mental health). Warns about cautious use of diagnosis and possible overdiagnosis linked to symptom checklists.
