<p>Previous research has identified impulsive personality
traits as significant risk factors for a wide range of risk-taking behavior,
substance use, and clinical problems. Most work has been conducted in primarily
White samples, leaving it unclear whether these patterns generalize to racial
and ethnic minorities, who have higher rates of negative consequences of substance
use behavior. The most widely used assessment of impulsive traits is the UPPS-P
Impulsive Behavior scale, which has strong psychometric properties across
demographic subgroups, such as gender and age; however, data supporting its use
in racial and ethnic minorities is less well-developed. The aims of this study
are to 1) examine the measurement invariance of the UPPS-P Impulsive Behavior
Scale-Short Form (Cyders et al., 2014) across racial minority groups and 2)
determine if impulsive personality traits differentially relate to substance
use outcomes across racial groups. Participants were 1301<sup>
</sup>young adults (ages 18-35, fluent in English), recruited through an online
survey for both college students at a large public university and Mechanical
Turk, a crowdsourcing online platform. Measurement invariance was assessed
using multigroup confirmatory factor analysis. Differential validity was assessed
using a structural equation modeling framework. I established model fit for each
racial group (White group: RMSEA= .067, CFI= .94; Black group: RMSEA= .071, 90% CFI= .952;
Asian American group: RMSEA= .073, CFI=
.94; Hispanic group: RMSEA=.081, CFI=.934). Based on change in CFI/RMSEA
indices, I concluded strong measurement invariance of the Short UPPS-P as a
valid scale of impulsive behavior across racial groups. In the White
group, findings indicated significant relationships between multiple SUPPS-P
traits and alcohol and substance use. In
the Asian American group, positive relationships were found between sensation
and alcohol use (<i>p</i>=.015) and negative urgency and drug use (<i>p</i>=.020).
I found that there were no differences in the relationships between the Short
UPPS-P traits and substance use outcomes across White and the racial and ethnic
groups studied (<i>p</i>’s>.06). </p>
