AB The UPPS Impulsive Behaviour Scale (with five dimensions of impulsive behaviour) is beingwidely used. One of the handicaps of this instrument is its relatively long administration time.This has led to the development of a short version: SUPPS-P. There are no studies comparingthe relationship between the SUPPS-P scores and the original UPPS-P scores. The objectivesof this study, therefore, were to analyse the psychometric properties, concordance ofperson measures, and efficiency of the SUPPS-P compared to those on UPPS-P, applyingan Item Response Theory Model. The UPPS-P and SUPPS-P were administered to 455undergraduate students. Confirmatory factorial analysis replicated structures reported in previousstudies: the five correlated factors structure and the model with two second-order factors(Urgency and Lack of Awareness) with Sensation Seeking dimension as a different factor.Rasch analysis show that both of the instruments presented adequate model-data fit. Theresults show the measurement for each dimension of UPPS-P offered more precision thanSUPPS-P. The structure of items location was maintained in each dimension of SUPPS-Pcompared to the UPPS-P, but with better person and item separation indices of the UPPS-Pdimensions. The concordance analysis reveals high correlations values between scores onboth versions. From the standpoint of reducing items, it can be considered that the reducedversion is more efficient. This study does not support the equivalence of items on the dimensionsof Sensation Seeking and Lack of perseverance.
