Measurement Invariance and Differential Relationship to Substance Use of the Short UPPS-P Impulsive Behavior Scale Across Racial Groups.

ABSTRACT: The Short UPPS-P Impulsive Behavior (SUPPS-P) scale assesses impulsive traits; however, its use among racial/ethnic minorities needs further testing. The aims of this study are to (a) test the measurement invariance of the SUPPS-P scale between White and racial/ethnic minority groups and (b) determine whether impulsive personality traits differentially relate to substance use outcomes across these groups. Participants were 1,301 young adults and recruited through a large public university or Amazon's Mechanical Turk. Multigroup confirmatory factor analysis concluded strong measurement invariance for Black, Asian American, and Hispanic/Latino groups, each compared with a White group. Most relationships between SUPPS-P traits and substance use did not differ across the groups compared, altho
