VASCONCELOS, Alina Gomide; TEODORO, Maycoln Leôni Martins; MALLOY-DINIZ, Leandro  and  CORREA, Humberto. Impulsivity components measured by the Brazilian version of the Barratt Impulsiveness Scale (BIS-11). Psicol. Reflex. Crit. [online]. 2015, vol.28, n.1, pp.96-105. ISSN 0102-7972.

The main purpose of this study was to investigate the psychometric properties of the Barratt Impulsiveness Scale (BIS-11). Content item analysis was conducted by seven doctoral students. A convenience sample of 897 students was submitted to BIS-11 and they also filled self-reports about Minor Mental Disorder and ADHD symptoms, alcohol use and cigarette smoking. Mean age was 27.32 (SD=8.69) years, 56% were female and 52% had incomplete college degree. Content and factorial analyses revealed that impulsivity was best represented by two latent factors labeled non-planning and inhibition behaviors. Test retest agreement tended to produce similar score patterns seven months after the first evaluation. Additionally, BIS-11 scores discriminated subjects in terms of cigarette smoking and psychopathological symptoms, which indicated evidences regarding criterion-related validity. The theoretical discussion was present based on the neuropsychological model of hot and cool aspects of executive function.
