Examination of a short English version of the UPPS-P Impulsive Behavior Scale

The current study examines a recently developed short English version of the UPPS-P Impulsive Behavior Scale. Participants were 251 undergraduate students (593% 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 English 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. This short UPPS-P scale should be considered a valid and reliable alternative to the full UPPS-P in English-speaking non-clinical adult samples. (C) 2014 Elsevier Ltd. All rights reserved.
