RT Article T1 Investigating Sex-Related Moderation Effects and Mediation Effects of Self-Control on Delinquency Among Portuguese Youth JF International journal of offender therapy and comparative criminology VO 65 IS 8 SP 882 OP 898 A1 Pechorro, Pedro A1 DeLisi, Matt A1 Quintas, Jorge A1 Gonçalves, Rui Abrunhosa A1 Maroco, João A2 DeLisi, Matt A2 Quintas, Jorge A2 Gonçalves, Rui Abrunhosa A2 Maroco, João LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/1757199772 AB Self-control refers to the ability to override impulses and behave in accordance with societal norms. Deficits in self-control are strongly associated with conduct problems, externalizing disorders, crime, and violence. The main aim of the present study is to investigate possible moderation and mediation effects related to self-control. A school sample of male (n = 257, M = 15.97 years, SD = .98 years) and female (n = 213, M = 15.79 years, SD = 1.03 years) youth from Portugal agreed to participate. Moderation analysis revealed that sex moderates the relationship between self-control and aggression, conduct disorder symptoms, and self-reported delinquency. Mediation analysis revealed that self-control mediates the relations between both triarchic psychopathic traits and dark triad traits, and the self-reported juvenile delinquency outcome. The findings suggest that self-control exerts significant effects on the criminal/antisocial-related variables examined among Portuguese youth.
