To identify the psychosocial and clinical correlates of attention-deficit hyperactivity disorder (ADHD) in a community sample of children and to examine the validity of a subclinical form of ADHD.
The sample of 449 children (mean age 9.2 years, SD 1.78 ; 53.6% boys) participated in the second stage of a community survey.
Of these, 359 (80%) screened positive at stage 1. On the basis of a structured diagnostic interview with a parent, children were classified into 1 of 3 mutually exclusive groups : ADHD (n=89), subthreshold ADHD (n=100), and non-ADHD (n=260).
As measured by the Children's Global Assessment Scale, the ADHD group was more impaired than the subthreshold group, which was more impaired than the non-ADHD group (p<. 05 for each test).
Children in the ADHD group were more likely to be male, to have mothers with a history of psychiatric treatment, to have fathers with a history of excessive alcohol use, and to live in low-income families with higher levels of family dysfunction (p<. 05 for all variables).
A model containing male gender, family dysfunction, and low income was most predictive of ADHD status (p<. 01).
ADHD was also associated with psychiatric comorbidity, especially disruptive behavior disorders.
These results support a dimensional approach to ADHD.
More severe forms of ADHD are associated with psychosocial adversity and psychiatric comorbidity.
