WILLHELM, Alice Rodrigues; PEREIRA, Anderson Siqueira  and  DE ALMEIDA, Rosa Maria Martins. Confirmatory factor analysis of the reduced version of the Barratt Impulsivity Scale for adolescents. Aval. psicol. [online]. 2020, vol.19, n.4, pp. 461-467. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2020.1904.17597.12.

The general aim was to evaluate the adequacy of the factorial structure of the Brazilian version of the Barratt Impulsivity Scale (BIS-11) for adolescents of both sexes and to suggest an abridged version of the scale with better psychometric properties. A total of 304 adolescents aged 13 to 18 years of the city of Porto Alegre were evaluated. The Barratt Impulsivity Scale was used. It was possible to observe a low fit index for the Brazilian model compared to the other indices and a good index for the Portuguese model. However, a reduced version of the scale was proposed, totaling 12 items. This version had adequate fit indices. The corrected Cronbach's alpha was 0.974. This study presents a good factorial analysis that identifies three factors of the original scale for the population of adolescents of both sexes in an abbreviated version of the scale.
