abstract="BACKGROUND: The Barratt Impulsivity Scale (BIS) is one of the most commonly used scales for the assessment of impulsiveness. This report describes the reliability and validity of the BIS-11. <br><br>SUBJECTS AND METHODS: The study was conducted in high school students (n = 763). The reliability was evaluated with analysis of internal consistency and homogeneity of the items. For the validity Pearson coefficient of correlation and the student t-test for independent sample were used. <br><br>RESULTS: The scale obtained a Cronbach alpha coefficient of 0,77, and the total scores of the scale correlated significantly with impulsivity according to DSM IV, impulsivity according to the teacher, suicide attempt and alcohol consumption. <br><br>CONCLUSIONS: The BIS-11 is a valid and reliable measure of impulsivity in this population.<p /><p>Language: es</p>",
