Patterns of diagnostic comorbidity in a community sample of children aged 9 through 16 years

Abstract

Secondary analyses of the data from the Puerto Rico Child Psychiatry Epidemiologic Study were done to provide information on the comorbidity of four major diagnostic domains (attention deficit disorders, conduct/oppositional disorders, depression and anxiety disorders). A high level of comorbidity was found among these four domains of child and adolescent psychopathology. In general the patterns of comorbidity were not affected by whether the data was put together by a clinician or by means of a computer algorithm scoring a structured interview. The patterns were not affected in any major way by who the informants were in the diagnostic process. Minor differences were found in certain comorbidity patterns depending on the sex and age of the subjects. Comorbidity was associated with level of impairment and to service utilization.
