The aim of the present study was to examine the psychometric properties of the Dirty Dozen scale, a brief measure of the Dark Triad, among a sample of 412 at-risk youths from Portugal (M= 13.19 years; SD = 1.41; age range = 12– 17 years), composed of male (n = 200; M= 13.32 years; SD = 1.41 years) and female youths (n = 212; M= 13.08 years; SD =1.41 years). As expected, our translation had a three-factor structure that was invariant across the sexes. Adequate psychometric properties were demonstrated in terms of internal consistency (i.e., Cronbach’s alpha and Omega coefficient), convergent validity (i.e., with measures of self-reported delinquency, and sensation seeking), discriminant validity (i.e., with measures of self-esteem,and self-control), criterion-related validity (i.e., with drug use, and risky sex), and know-groups validity (boys versus girls). We also found that sex differences in self-reported delinquency were partially mediated by sex differences in the Dark Triad traits. Our findings suggest the Dirty Dozen is a valid and useful measure in the study of at-risk for delinquency adolescents PSICOLOGIA 705 JOVEM 100424 RISCO 8490 DELINQUÊNCIA JUVENIL 689 PSICOPATIA 5166 NARCISISMO 102931 AGRESSIVIDADE 2117 COMPORTAMENTO DE RISCO 6300 PORTUGAL 279 PECHORRO Pedro 12959 JONASON Peter K. 106802 RAPOSO Vanessa 12980 MAROCO João 12967 159.9PEC 0 159_000000000000000_9PEC 2021-12-17 3708 15468 DGRSP DGRSP DGRSP37081236275 159.9PEC 2021-12-17 0 MO oferta
