Impulsivity is a multidimensional construct playing a pervasive role in psychiatry and neuropsychology. Lynam et al. (2006) have
developed the 59-item UPPS-P Impulsive Behavior Scale, which assesses five distinct impulsivity dimensions: positive urgency,
negative urgency, lack of perseverance, lack of premeditation, and sensation seeking. The short, 20-item version of the UPPS-P
(SUPPS-P; Billieux et al. Comprehensive Psychiatry, 53(5), 609–615, 2012) has been developed and adapted into several languages,
including English, French, Italian, Spanish, and Arabic. The aim of the present study was to test four theoretical models of
the SUPPS-P in a large sample of Hungarian adults. A total of 15,703 participants (64.76% male; Mage = 33.42 years, SD = 11.06)
completed the SUPPS-P using an online questionnaire. Confirmatory factor analyses corroborated the first-order five-factor model
of impulsivity and a hierarchical model representing three higher-order constructs (urgency, lack of conscientiousness, sensation
seeking), whereas the one-factor and three-factor model were not supported. The factor structure of the SUPPS-P preserved the
original, theory-driven structure of the UPPS-P model and this instrument demonstrated good internal consistency. Hypersexual
behavior consequences were positively associated with most SUPPS-P components, thus criterion validity was also supported. The
SUPPS-P had strong psychometric properties that reflected the theoretical structure of the original UPPS-Pmodel, thus it constitutes
a theoretically grounded and time saving multidimensional instrument for assessing impulsivity.
