An adolescent sample of twins pairs recruited through the Colorado Twin
Registry and Longitudinal Twin Study were assessed using standardized psychiatric
interviews and personality assessments. Symptom counts for conduct disorder
and attention deficit hyperactivity disorder, along with a measure of substance
experimentation and novelty seeking, were used as indices of a latent behavioral
disinhibition trait. Statistical models demonstrated that a variety of adolescent
problem behaviors may share a common underlying genetic risk.
