Introduction. Although an association between attention deficit hyperactivity disorder (ADHD) and personality disorders has been observed in adult population, no descriptions in Chilean adolescents have been reported.

Objective. To explore personality profiles in Chilean adolescent patients diagnosed with ADHD.

Method. Non-experimental, comparative design, convenience sample with 61 adolescent patients (13-19 years old) diagnosed with ADHD who completed the Millon Adolescent Clinical Inventory (MACI) questionnaire. Results compared parameters for the Chilean adolescent population and patients in the study. Attending psychiatrists completed a medical history file (comorbidities, pharmacological treatment and factors associated with mental health). Multivariate statistics, cluster analyses, and means comparison analyses were performed. This project was approved by the Ethics Committee of the University of Chile.

Results. The personality profile of female adolescent patients with ADHD resembles that of the general female population, while the profile of the male patients is similar to that of the patient’s parameter group. Cluster analysis identified two personality sub-profiles: 25% of the subjects belonged to cluster 1, which was characterized by higher scores for different personality traits, expressed concerns, and clinical syndromes, compared with subjects from cluster 2. There were no differences regarding gender, ADHD clinical presentation, use of medication, adverse childhood experiences (ACEs), type of school, grade retention, or, applicable only to the female group, comorbidities in belonging to cluster 1. Only the presence of comorbidity in male subjects was associated with cluster 1 membership.

Discussion and conclusion. Adolescent patients diagnosed with ADHD differed significantly in some personality traits when compared to Chilean parameters for the MACI. Of the adolescents studied, 25% have maladaptive personality characteristics.
