The present project utilized the Five Factor Model of personality (FFM; McCrae & Costa, 1990) to clarify the multi-faceted nature of impulsivity. The NEO-PI-R and a number of commonly used impulsivity measures were administered to over 400 young adults. Exploratory factor analyses identified four distinct personality facets associated with impulsive-like behavior which were labeled urgency, (lack of) premeditation, (lack of) perseverance, and sensation seeking. Each of these traits was marked by a different facet of the FFM. Following the initial factor identification, scales to measure each of the personality facets were created and combined to form the UPPS Impulsive Behavior scale. Implications for the understanding of impulsive behavior and the FFM are discussed, as are future applications of the UPPS impulsive behavior scale.
