| Summary: | Objective: Impulsivity appears to be best conceptualized as a multidimensional construct. For example, the UPPS-P model posits that there are five underlying facets of impulsivity. The present study examined the expression of the UPPS-P facets in daily life using experience sampling methodology. A specific goal of the study was to examine positive urgency, a facet added to the original UPPS model, and its convergence and divergence from the negative urgency facet. Method: A large nonclinical sample of young adults (n = 294) completed the UPPS-P scale and was signaled to complete questionnaires assessing daily affect, cognitions, sense of self, and impulsive behaviors eight times a day for 7 days. Results: Results indicated that the UPPS-P facets are associated with disruptions in affect, cognitions, and behavior in daily life. Furthermore, all of the UPPS-P facets were associated with impulsivity in daily life. Contrary to expectation, positive urgency was associated with negative affect rather than positive affect and had a profile indistinguishable from negative urgency. Conclusions: These results generally support a four-factor model of multidimensional impulsivity with a general overall urgency factor instead of separate positive and negative urgency facets. © 2018 Wiley Periodicals, Inc.
