Abstract

Secondary analyses of the data from the Puerto Rico Child Psychiatry Epidemiologic Study were undertaken to provide information on the comorbidity patterns of ADHD. A high level of comorbidity was found among ADHD and other diagnostic categories, particularly the conduct/oppositional group. Comorbidity was associated with level of impairment and with service utilization.
