Resumo(s)
The aim of the present study was to examine the psychometric properties of the
Barratt Impulsiveness Scale version 11 (BIS-11) among a forensic sample of
incarcerated male juvenile offenders (N = 221). Principal Component Analysis
with Promax rotation revealed the expected 6-factor structure, but Confirmatory
Factor Analysis of the 6-factor first-order and the 3-factor second-order factorial
structures did not present sufficiently good fits. Despite that, the Portuguese
adaptation of the BIS-11 demonstrated generally acceptable psychometric
properties in terms of internal consistency, mean inter-item correlation,
convergent validity, discriminant validity, and concurrent validity that justifies its
use among the youth forensic population. Statistically significant associations
were found with age of crime onset, conduct disorder, crime seriousness, alcohol
use and drug use.
