--- - |2+ Abstract 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. - Journal of Personality, Volume 86, Issue 5, Page 841-852, October 2018.
