Validation of a Korean Version of the Short UPPS-P Impulsive Behavior Scale for Children (UPPS-P-C-short)

초록

Introduction Impulsivity is a multifaceted construct that plays an important role in various problem behaviors in children and adolescents. Whiteside and Lynam(2001) first developed a scale to assess four different dimensions of impulsivity, the UPPS(negative urgency- lack of premeditation- lack of perseverance- sensation seeking), and later positive urgency was added to the original model(Cyders & Smith, 2008; Cyders et al., 2007). The UPPS-P was widely used in adults and was validated in many different languages. The UPPS-P model is well applied in numerous psychological disorders of children including ADHD. The purpose of this study was to validate a Korean version of the Short UPPS-P Impulsive Behavior Scale for Children (UPPS-P-C-short) which was developed by Geurten et al. (2021). Method Participants in the control group were 330 children (164 males, 166 females) enrolled in 2 elementary schools in Korea whose age ranged from 10 to 12 years (M=11.02, SD=.79). Among this sample, 107 children were retested 6 months later. The Korean UPPS-P-C-short (20 items) and CBCL 6-18 were administered in both waves, and the Barratt Impulsiveness Scale-11 was added in wave 2. The ADHD group consisted of 94 children (71 males, 23 females) recruited from the psychiatry department of two major hospitals in Korea whose age ranged from 7 to 12 years (M=8.85, SD=1.61). They completed the Korean UPPS-P-C-short during their psychological evaluation. Results Confirmatory factor analysis 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 consciousness; and (3) sensation seeking remained as a separate dimension. Reliability analysis demonstrated that the 5 factors of the Korean UPPS-P-C-short had acceptable internal consistency and test-re
