- Bold, mean and disinhibited: getting specific about the mediating role of self-control and antisocial outcomes in youthPublication . Pechorro, Pedro; DeLisi, Matt; Gonçalves, Rui Abrunhosa; Marôco, J. P.Self-control and psychopathy are correlated with antisocial behaviors among diverse samples, and a spate of recent studies examined their direct associations with criminal outcomes. However, research has largely overlooked mediation effects between psychopathy, self-control and deviant outcomes. The current study examined self-control mediation effects related to the triarchic psychopathy construct and juvenile delinquency, crime seriousness, conduct disorder (CD), and aggression outcomes. The sample consisted of N ¼ 567 (M ¼ 15.91 years, SD ¼ 0.99, range ¼ 14–18 years) southern-European youth from Portugal. Study design was cross-sectional, quantitative and non-experimental. Mediation analysis using path analysis procedures indicated that low self-control mediates the relation between the Boldness, Disinhibition and Meanness factors of the triarchic psychopathy construct and the delinquency, crime seriousness, CD and aggression outcomes. Findings suggest that self-control is a mediator of triarchic psychopathic features and diverse externalizing behavior outcomes, which adds specificity to their interrelationship as general predictors of antisocial behavior.
- Examination of Grasmick et al.’slow Self-control Scale and of a Short Version With Cross-Gender Measurement InvariancePublication . Pechorro, Pedro; DeLisi, Matt; Pacheco, Catarina; Gonçalves, Rui Abrunhosa; Marôco, J. P.; Quintas, JorgeGrasmick et al.’s Low Self-Control Scale (LSCS) is considered the gold-standard of self-control measures due to the frequency of its use in criminology. The aim of the present study is to examine the psychometric properties of the LSCS from a more modern psychometric perspective and develop a shorter version. Our sample consisted of young adults (N=610, M=21.33years, SD=3.09) from Portugal. The six-factor intercorrelated model of the LSCS showed an adequate fit, but models that would legitimate using a total score could not be confirmed. The subscales’ intercorrelations revealed some low non-significant correlations. The six subscales showed distinctive correlates with other measures, with three subscales presenting some problematic correlations. Confirmatory factor analysis was subsequently used to develop a three-factor shorter version with strong cross-gender measurement invariance and good reliability. Findings have implications for the validity of the general theory of crime specifically which components of self-control have the greatest empirical linkages to conduct problems and related deviance.
- Dark triad personalities, self-control, and antisocial/criminal outcomes in YouthPublication . Pechorro, Pedro; DeLisi, Matt; Gonçalves, Rui Abrunhosa; Braga, Teresa; Marôco, J. P.The Dark Triad composed of psychopathy, Machiavellianism, and narcissism, and also self-control are consistently related to antisocial and criminal externalizing outcomes. In the present study, we examined whether self-control mediates the relationships between the Dark Triad and delinquency, conduct disorder, and crime seriousness outcomes. The sample consisted of 567 adolescents (M = 15.91 years, SD = 0.99 years, range = 14– 18 years) from Portugal. Self-control mediated the association between psychopathy and Machiavellianism (but not narcissism) and self-reported juvenile delinquency, conduct disorder symptoms, and crime seriousness. One reason antisocial/criminal behaviors are common in those characterized by psychopathy and Machiavellianism relates to their deficits in selfcontrol as suggested by general theories. Within the nomological network of dark traits, narcissism appears to have enduring and unmediated associations with externalizing features and conduct problems. Our findings add to the literature modeling the Dark Triad along with self-control to elucidate its contributions to antisocial/criminal outcomes in youth.
- An antisocial alchemy: Psychopathic traits as a moderator of the different forms and functions of aggression in delinquency and conduct disorder among youthPublication . DeLisi, Matt; Pechorro, Pedro; Gonçalves, Rui Abrunhosa; Maroco, J. P.The aim of the present study is to examine the possible role of psychopathic traits as a moderator of the aggression-antisociality/delinquency link. Our sample was composed of 567 youth (M = 15.91 years, SD = 0.99 years, age range = 14-18 years) from Portugal. Results indicated that psychopathic features significantly moderate four different forms and functions of aggression - proactive overt, proactive relational, reactive overt, and reactive relational - when predicting delinquency. However, psychopathic traits only significantly moderate proactive relational aggression when predicting Conduct Disorder. Psychopathic traits and aggression constitute an antisocial alchemy for antisocial behavior but more research is needed about moderation effects therein particularly among clinical and justice system involved samples of youth to inform behavioral interventions.
