Of these, only the NPI-13 short version demonstrated a good fit in terms of its factor structure. The NPI-13 also showed promising psychometric properties in terms of its internal consistency, convergent validity, discriminant validity, and criterion-related validity. Statistically significant associations were found with age of crime onset, crime seriousness, conduct disorder symptoms, alcohol abuse, and cannabis use. These findings justify the use of the NPI-13,especially its Entitlement/Exploitativeness dimension, among incarcerated male youths. aPSICOLOGIA aPSICOMETRIA aAVALIAÇÃO aINVENTÁRIO DE PERSONALIDADE aDELINQUÊNCIA JUVENIL aNARCISISMO aCOMPORTAMENTO DE RISCO aCENTRO DE DETENÇÃO aPORTUGAL aPECHORRObPedro aGONÇALVESbRui Abrunhosaf1958- aGENTILEbBrittany aRAYbJames V. aNUNESbCristina j159.9PEC
