Abstract OBJECTIVE: The aim of this study was to compare the pattern of comorbidity in referred samples of Attention-Deficit/Hyperactivity Disorder (ADHD) patients from two different geographic areas in Brazil. METHODS: The diagnoses of ADHD and comorbid conditions, according to DSM-IV criteria, were achieved in both clinics through semi-structured interview methodology, complemented by clinical interviews with the children or adolescents and their parents. RESULTS: We assessed 343 ADHD children and adolescents in Porto Alegre (capital of the southernmost state of the country) and 78 ADHD youths in Rio de Janeiro (capital of a southeastern state). Although a significant difference in the prevalence of ADHD without comorbidity was detected between the two groups (p = 0.02), no significant difference was detected in the profile of comorbidities between them. Main ADHD comorbidities in both samples were: a) Oppositional Defiant Disorder (Porto Alegre = 39.1\%; Rio de Janeiro = 51.3 \%); b) Anxiety Disorders (Porto Alegre = 24.2\%; Rio de Janeiro = 30.8 \%); c) Conduct Disorder (Porto Alegre = 13.7\%; Rio de Janeiro = 17.9 \%); and d) Major Depression and/or Dysthymia (Porto Alegre = 11.4\%; Rio de Janeiro = 10.3 \%). CONCLUSIONS: Our results from clinical samples in a developing country with a diverse culture suggest the crosscultural validity of the ADHD comorbidity profile.
