Versão portuguesa da escala de impulsividade EIB-11: propriedades psicometricas
Resumen. El presente estudio tuvo como objetivo adaptar y validar la escala de impulsividad de Barrat (1) para la población portuguesa y analizar sus características psicométricas. Primero, el BIS-11 se tradujo y adaptó a la población portuguesa, evaluando la consistencia interna y la estabilidad temporal en la que se obtuvieron buenos valores de consistencia interna, confirmando la estabilidad temporal de la medición mediante la obtención de correlaciones significativas entre la prueba y la nueva prueba. coeficiente de α de Cronbach en los dos momentos (0.728) y la nueva prueba (0.733). Después de este procedimiento, BIS-11 pasó a llamarse Escala de Impulsividad (EIB-11). En segundo lugar, en una muestra de 355 sujetos adultos de ambos sexos, se verificó nuevamente el comportamiento de consistencia interna (0.762) y se realizó el análisis factorial exploratorio, que resultó en 9 factores, seguido del análisis paralelo que extrajo una solución confiable de 4 factores. Los resultados mostraron que el EIB-11 tiene características psicométricas adecuadas, aunque su uso debe realizarse con cuidado, teniendo en cuenta el fenómeno que evalúa.

Portuguese version of EIB-11 impulsivity scale: psychometric properties
Abstract. The present study had the objective of adapting and validating Barrat’s impulsivity scale (1) for the Portuguese population and analyzing their psychometric characteristics. First, BIS-11 was translated and adapted to the Portuguese population, evaluating the internal consistency and temporal stability in which good values ​​of internal consistency were obtained, confirming the temporal stability of the measurement by obtaining significant correlations between the test and the retest and the coefficient of Cronbach’s α in the two moments (0.728) and the retest (0.733). After this procedure BIS-11 was renamed Impulsivity Scale (EIB-11). Second, in a sample of 355 adult subjects of both sexes, the internal consistency behavior (0.762) was again verified and the exploratory factorial analysis was conducted, resulting in 9 factors, followed by the parallel analysis that extracted a reliable solution of 4 factors. The results showed that EIB-11 have adequate psychometric characteristics, although its use must be carried out with care, taking into account the phenomenon that it evaluates.
