Extreme personality poses risk of ADHD, conduc...( Children with personalities marked by a...),Health

FSU psychology professors Jeanette Taylor and Chris Schatschneider, FSU doctoral student Kelly Cukrowicz and University of Minnesota Professor William Iacono found that children with ADHD or conduct disorder had more negative emotions - aggressiveness, tension and feelings of being exploited, unlucky or poorly treated - and lower constraints - a tendency to break rules and engage in thrill-seeking behavior - than children with neither of the disorders. Not surprisingly, those children who have both ADHD and conduct disorder had the most extreme personality profiles.

"This helps us to understand that personality is part of the bigger picture of these disorders," Taylor said. "That could help with initial assessments or lead to unexpected discoveries or potential interventions. We're saying to researchers and clinicians, 'Think about personality when you look at these issues.' "

The study, published in the Journal of Child Psychology and Psychiatry, is the first to investigate personality trait patterns among children who have ADHD, conduct disorder or a combination of both. It is important to learn more about the co-occurrence of ADHD and conduct disorder because the consequences are so severe, Taylor said.

"It's more than the sum of its parts," she said, explaining that children and adolescents with a combination of the two disorders are at much higher risk of school failure, criminal activity, substance abuse and depression. Previous studies have indicated that between 15 to 35 percent of children with ADHD also have conduct disorder.

Between 3 percent and 5 percent of U.S. school age children are estimated to have ADHD, a disorder that encompasses symptoms of hyperactivity,
