Propiedades psicométricas de la escala de impulsividad de Barratt en adolescentes ecuatorianos

Abstract

Impulsivity implies the lack of reflection for making decisions without taking into account the possible consequences that may be triggered by them, it is related to the lack of impulse control, being carried away by the impression of the moment, manifesting an absence of damage planning for the individual. Impulsivity occurs more in adolescents due to a mismatch between the emotional and affective system, which in turn is quite active at this stage. The main objective of the study was to determine the psychometric properties of the Barratt impulsivity scale (BIS-11) in a sample of 412 Ecuadorian adolescents between 12 and 17 years of age (M=15.5, SD=0.743). The study design was non-experimental and cross-sectional. The results obtained showed that the Barratt impulsivity scale (BIS-11) has a total reliability of 0.777 leaving it in a moderate range, the exploratory factor analysis distributed the total scale in 6 factors. As for the mean impulsivity score between men and women, it was found that there were no significant differences. Finally, the BIS-11 has psychometric properties that should be handled with caution for its application in Ecuadorian adolescents.
