NEO PI-R profiles of adults with attention deficit disorder

The personality functioning of adults diagnosed with attention deficit disorder (ADD) without comorbid psychiatric illness was examined. NEO PI-R profiles in a group of 25 adults referred for ADD evaluation meeting criteria for this diagnosis without any history of other psychiatric disturbance were compared to profiles from a control group of 23 nonpsychotic adult outpatients being treated with psychotherapy. All participants completed self-report measures of ADD symptoms as well as the NEO PI-R (Form S). The ADD adult group obtained significantly higher scores in the Neuroticism domain and significantly lower scores in the Conscientiousness domain than the outpatient comparison group. The NEO PI-R appears useful to the understanding of ADD in adulthood.
