Abstract

Objective
Impulsivity is a multifaceted construct that plays an important role in various problem behaviors in children and adolescents. The purpose of this study was to validate a Korean version of the short UPPS-P Impulsive Behavior Scale for Children.
Methods
Participants were 330 children (166 female) from 2 elementary schools in Korea and 94 attention deficit hyperactivity disorder (ADHD) children (23 female) from two major hospitals. The Korean short UPPS-P Impulsive Behavior Scale for Children (UPPS-P-C) (20 items), Child Behavior Checklist for Ages 6–18 (CBCL 6–18), and Barratt Impulsiveness Scale-11 (BIS-11) were administered. 107 children from the control group were retested 6 months later.
Results
Confirmatory factor analysis (CFA) conducted in the control group supported a 5-factor hierarchical model in which 1) positive and negative urgency factors are loaded on a higher-order factor of general urgency; 2) lack of perseveration and lack of premeditation factors are loaded on a higher-order factor of lack of conscientiousness; and 3) sensation seeking remained as a separate dimension. Reliability analysis demonstrated that the 5 factors of the Korean short UPPS-P-C had acceptable internal consistency and test-retest reliability. Lack of premeditation and lack of perseveration subscales showed significant correlations with measures of problem behaviors in CBCL and all the subscales were correlated with the BIS-11. The ADHD group showed significantly higher scores in lack of premeditation, lack of perseveration, positive urgency, and negative urgency subscales.
Conclusion
This study indicates that the Korean version of short UPPS-P-C has adequate reliability and validity. It may be a valid tool to assess impulsivity of healthy children as well as ADHD.
