    Examination of a Short Version of the UPPS-P Impulsive Behavior Scale
    (Elsevier B.V., 2014-09) Cyders, Melissa A.; Littlefield, Andrew K.; Coffey, Scott; Karyadi, Kenny A.; Department of Psychology, School of Science
    The current study examines a recently developed short version of the UPPS-P Impulsive Behavior Scale. Participants were 251 undergraduate students (59.3% male; mean age = 21.16 ( SD = 4.18); 72% Caucasian). The short version generally replicated the internal consistency (0.74 – 0.88 across subscales) and inter-scale correlations of the full UPPS-P. Moreover, the estimated loss of shared variance was small (0% – 6.4% reductions across subscales) as compared to a 66% time- savings. Structural equation modeling replicated previously supported factor structures and relationships to external outcomes using the full UPPS-P. The short UPPS-P scale should be considered a valid and reliable alternative to the full UPPS-P.
