Psychometric properties and normative data of the Brazilian version of UPPS-P Impulsive Behavior Scale

Abstract The aime was to examine the factor structure, reliability and to obtain preliminary parameters of the Brazilian adaptation of the UPPS-P Impulsive Behavior Scale, a widely self-report measure used to assess impulsive behavior, in research and clinical setting. The scale is composed of 59 items assessing five factors of impulsivity: (1) positive urgency, (2) negative urgency, (3) lack of premeditation; (4) lack of perseverance; (5) sensation seeking. In the present study 718 participants (504 women and 214 men), with mean age 38.5 (SD = 12.4) who were recruited online fulfilled the UPPS-P scale. A Confirmatory Factor Analysis (CFA) presented appropriate goodness of fit for the five-factor model, and a Multi-Group Confirmatory Factor Analysis (MGCFA) revealed evidence of invariance of its psychometric parameters as a function of gender. Our results showed that the Brazilian Portuguese version of UPPS-P presents good psychometric properties and the same five-factor structure of the original version of UPPS-P.
