Background.

There are few studies linking personality and Attention Deficit Hyperactivity Disorder (ADHD) in adolescents.

Research objective:

to study differences between cases with ADHD and the general population in personality prototypes (PRP) derived from the Millon Clinical Inventory for Adolescents (MACI).

Material and Method.

Analytical observational design. Random sampling in the general population (n = 461) and consecutive of patients with ADHD evaluated according to DSM-5 criteria (n = 85), in adolescents between 13 and 17 years old. Measurement instruments: MACI and Adolescent Symptom Inventory.

Results:

ADHD presents a significantly higher mean in Doleful, Forceful, Unruly, Oppositional, Self-demeaning and Borderline PRP and the general population in Submissive and Conforming PRP. The PRP model that best predicts ADHD includes male sex and the Forceful, Borderline, Submissive and Self-demeaning PRP. The model classifies 82.4% of the cases.

Conclusion.

ADHD cases have differential PRP in comparison with the general population, which invites their clinical study and therapeutic intervention. The study offers a novel image of PRP in ADHD and opens new lines of research that include personality when explaining the heterogeneity of the disorder.
