Abstract
The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent
factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited
from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child Behavior Checklist, Early
Adolescent Temperament Questionnaire, and California Q-Sort. Children completed the Stop and Trail-Making Task. Specific inattention
was associated with depression/withdrawal, slower cognitive task performance, introversion, agreeableness, and high reactive
control; specific hyperactivity-impulsivity was associated with rule-breaking/aggressive behavior, social problems, errors
during set-shifting, extraversion, disagreeableness, and low reactive control. It is concluded that the bifactor model provides
better explanation of heterogeneity within ADHD than DSM-IV ADHD symptom counts or subtypes.
