Validation of a short Korean version of the UPPS‐P Impulsive Behavior Scale.

Abstract: Introduction: The purpose of the present study was to validate a Korean version of the short UPPS‐P Impulsive Behavior Scale (UPPS‐P). Methods: This study included 724 undergraduate students who completed the following questionnaires: the Korean UPPS‐P, Beck Depression Inventory, State‐Trait Anxiety Inventory, Eating Disorder Inventory‐2, Alcohol Use Disorder Identification Test, and Canadian Problem Gambling Index. Results: A confirmatory factor analysis supported a 5‐factor interrelated model. The internal consistency coefficients for the 5 factors of the short Korean UPPS‐P were acceptable (.65‐.78 across the subscales), and the subscales of the short Korean UPPS‐P were strongly correlated with the long UPPS‐P subscales. External validity was demonstrated by associations between the subfactors of impulsivity and various psychopathologies, including depression, anxiety, binge eating, alcohol abuse, and gambling. Discussion: The present results indicate that the short Korean version of the UPPS‐P may be a useful and reliable alternative to the original long‐form UPPS‐P. [ABSTRACT FROM AUTHOR]
