Principal Component Analysiswith 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. aPSICOLOGIA aPSICOMETRIA aIMPULSIVIDADE aDELINQUÊNCIA JUVENIL aCENTRO EDUCATIVO aPORTUGAL aPECHORRObPedro  aGONÇALVESbRui Abrunhosaf1958- aMAROCObJoão  aRAYbJames V.  j159.9PEC
