Diagnosis, which currently relies on the DSM-V criteria, is complex. This research proposes an integrated procedure for ADHD diagnosis in children, improving the diagnostic process and scientific research on etiopathology. Methods: We conducted a clinical report on ADHD diagnosis in children (n=92) between the ages of 8 and 13, based on the results of the application of different scales to parents of school-age children in Chile. The children were divided into two groups, those with an ADHD diagnosis (n= 44) and those without (n=48) (24% females). Results: The results revealed statistically significant differences between groups for scales EDAH y SDQ-Cas, Conners Comprehensive Behavior Scale, Conners Parent Scale and the criteria according to the DSM-V and its dimensions, with the exception of inattention. Conclusions: The findings indicate the importance of appropriate criteria and procedures to establish a diagnosis and implement effective interventions in ADHD.
