Measurement and Functional Equivalence of a Reduced Version of the UPPS Impulsivity Scale Among Hispanic, Non-Hispanic Black, and Non-Hispanic White Adolescents



The current study aimed to assess the measurement equivalence and functional equivalence of the UPPS (Urgency, Premeditation, Perseverance, Sensation Seeking) Impulsivity Scale among three ethnoracial adolescent samples in the U.S. seventh-grade students who self-identified as Hispanic (n = 472), non-Hispanic Black (n = 89), or non-Hispanic White (n = 90), and completed an English-language version of the Child version of the UPPS, which was shortened and modified to include positive urgency items. Through a series of confirmatory factor analyses, the UPPS demonstrated configural, metric, and partial threshold invariance. Fisher’s r-to-z transformations were used to assess the functional equivalence of the UPPS against well-validated measures of self-regulation and mental health commonly associated with impulsivity. We found some group differences in the magnitude of associations. Yet, overall, this study provides evidence that the UPPS can be used to measure distinct factors of impulsivity among Hispanic, non-Hispanic Black, and non-Hispanic White adolescents.
