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.
