ABSTRACT
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.
RESUMO
O objetivo principal desse estudo foi investigar as características psicométricas da Barratt Impulsiveness Scale (BIS-11). A análise do conteúdo dos itens foi realizada por sete doutorandos. A amostra foi composta por 897 estudantes submetidos a BIS-11 e a medidas de autorrelato sobre a presença de sintomas de Transtorno Mental Comum e TDAH, uso de álcool e tabagismo. A idade média foi de 27,32 (DP=8,69) anos, 56% eram mulheres e 52% tinham educação superior incompleta. Análises de conteúdo e fatorial indicaram que a impulsividade é representada mais adequadamente por dois fatores denominados dificuldade de planejamento e controle inibitório. Concordância teste-reteste indicou que os escores se mantiveram estáveis após sete meses. Adicionalmente, os escores da BIS-11 discriminaram os indivíduos em termos de tabagismo e sintomas psicopatológicos, indicando evidências de validade de critério. A discussão dos resultados foi baseada no modelo neuropsicológico dos componentes quentes e frios das funções executivas.
