The current study examines a recently developed short English 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 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.
本研究考察了 UPPS-P 冲动行为量表的一个新的英文短版。参与者为 251 名本科生（59.3%为男性；平均年龄=21.16（SD=4.18）；72%为白种人）。短版通常复制了完整的英文 UPPS-P 的内部一致性（各分量表为 0.74-0.88）和分量表间的相关性。此外，与节省 66%的时间相比，估计的共享方差损失较小（各分量表减少 0%-6.4%）。结构方程模型使用完整的 UPPS-P 复制了先前支持的因子结构和与外部结果的关系。在英语非临床成人样本中，这种简短的 UPPS-P 量表应该被视为完整 UPPS-P 的有效和可靠替代。
