Longitudinal assessment of callous/impulsive traits, substance abuse, and symptoms of depression in adolescents: a latent variable approach.

Latent variable structural modeling was used to examine the associations among callous/impulsive personality traits, substance abuse, and symptoms of depression in a sample of 156 adjudicated male adolescents. Assessments were conducted at baseline and 6-month follow-up. The results highlight an unfolding of interrelationships among disturbances in personality, substance use, and mood over time.
