Facets of the Five-Factor Model (FFM) were examined in order to understand its interaction with Attention Deficit Hyperactivity Disorder (ADHD)-symptoms. By utilizing archival data, in a correlational design, adults between the ages of 18-66 were tested for the presence of ADHD, which was then compared with data gathered from the NEO-PI-R. Comorbid psychiatric conditions often associated with ADHD were accounted for in the design. Results partially supported the hypotheses, specifically, that altruism was inversely related to Impulsivity, as predicted. However, other findings largely did not support a relationship between other specific NEO-PI-R facets and ADHD. Other significant relationships that were not predicted were also established and discussed. The impact of these findings includes the utility of facets in predicting ADHD symptoms and the potential influence of compensation in an adult ADHD population. Limitations to this study were also indicated.
