Impulsivity has been linked to several risky behaviours, however, the multifaceted conceptualization of the construct has hardly been studied regarding adolescent antisocial behaviour. Thus, the aim of this study was to analyse the influence of impulsivity facets assessed by the UPPS-P scale on different types of antisocial behaviours (i.e. aggression, rule-breaking behaviour, theft, and vandalism), and whether sex moderated those relationships. The sample was composed of 575 Spanish adolescents aged 14 to 18. Four hierarchical multiple regression models were carried out, one for each antisocial behaviour. Results show that positive urgency and sensation seeking were related to all behaviours above and beyond prediction from the other facets. Lack of premeditation only predicted aggression whereas lack of perseverance predicted all nonviolent behaviours. After taking into account all the impulsivity facets, negative urgency was no longer related to antisocial behaviours. Males displayed higher levels of sensation seeking and sex moderated a quarter of the associations between impulsivity facets and antisocial behaviour. Results support the multidimensional conceptualization of impulsivity and reveal differential effects on diverse typologies of antisocial behaviour.

The aim of this study was to assess the effects of the variables related to family functioning (parental monitoring, family support, and family conflict) on juvenile antisocial behavior either directly or indirectly through the choice of deviant friends. Thus, the sample consisted of 764 adolescents from the Autonomous Community of Galicia (Spain), from juvenile offender centres (mean age=17.12, 87.4% males) and students from local schools (mean age=16.06, 45.5% males). The scales of Valoración del Riesgo en Adolescentes Infractores [Juvenile Offenders Risk Assessment] on parental monitoring, family conflict, family support, antisocial peer group, and antisocial behavior, were applied. The results of structural equation modelling showed a better fit of the mediation model. The results are discussed in terms of their implications for the prevention, risk assessment, and management of juvenile offenders

The relationship between Dark Triad traits and risky behaviours has been shown in recent years. However, few studies have attempted to disentangle this relationship using a person-centred approach. The goal of the current study was to identify subgroups of individuals on the basis of their scores on Machiavellianism, psychopathy, and narcissism and analyse the differences between them in a set of risky behaviours (i.e., frequency of substance use, reactive and proactive aggression, risk perception and risk engagement, and problematic internet use). The sample consisted of 317 undergraduates aged 18–34 (46% males). The results of the latent profile analysis showed five subgroups of individuals that were identified based on their scores on the Dark Triad traits: low-Dark Triad, narcissistic, Machiavellian/narcissistic, psychopathic, and Machiavellian/psychopathic. Overall, the Machiavellian/narcissistic and Machiavellian/psychopathic subgroups showed higher scores for most risky behaviours. The low-Dark Triad scored higher for risk perception. No significant differences between subgroups were found as regards frequency of alcohol, tobacco, and cannabis use. These findings suggest that the combination of the Dark Triad traits lead to more negative outcomes as regards risky behaviour than individual components. Moreover, they highlight the relevance of using a person-centred approach in the study of dark personalities.

The Dark Triad traits (DT; Machiavellianism, psychopathy, and narcissism) have been repeatedly labeled as a constellation of traits that are characterized by a dishonest and self-focused approach to interpersonal relations. Personality psychologists suggest that these traits make some people more susceptible than others to intergroup bias, threat, and aggression. Thus, in order to delve into a psychological profile prone to accepting and justifying sexist attitudes, the aims of the current study were to analyze the presence of DT and sexist attitudes in a sample of 367 adolescents (M_age = 15.12, SD = 0.88; 50.1% males), find out the relationships that DT has with both hostile and benevolent sexism, and analyze the relevant differences between sexes in these relationships. The results indicated higher scores in DT and Ambivalent sexism for males. The correlations of Machiavellianism with psychopathy, and psychopathy with narcissism revealed significantly higher associations in males than females. The structural equation modeling of the bifactorial model, characterized by a global latent factor that encompasses the common characteristics of DT—along with the three specific factors of Machiavellianism, psychopathy, and narcissism—showed that the global latent factor of DT was related to both hostile and benevolent sexism in males and females. Singularly, narcissism was related to benevolent sexism in males, and psychopathy was related to hostile sexism in females. Finally, this research discusses the implications of these results on the implementation of positive models of interpersonal relationships in adolescence towards dating violence prevention.

According to the theory of planned behavior (TPB), intentions to perform a specific behavior are the result of attitudes, norms, and perceived control, and in turn, intentions and perceived control are the main predictors of the behavior. This study aimed to test the applicability of TPB in predicting alcohol use in normative pre-adolescents. The sample was composed of 755 Spanish adolescents aged 11 to 15 (M = 12.24; SD = 0.56), 47.1% females, from 12 state secondary schools in Spain. The results of path analysis indicate that positive attitudes towards alcohol, favorable norms towards alcohol, and offer vulnerability (perceived control) are significantly positively related to intentions to use alcohol as well as negatively related to actual behavioral control (i.e., actual strategies to avoid alcohol use). In turn, intentions to use and actual control predict higher alcohol frequency and heavy drinking. Significant indirect effects of these antecedents were found on alcohol outcomes through the mediation of intentions and actual control. The findings suggest that the validity and applicability of the TPB in normative pre-adolescents depend on the severity of alcohol use and point to a need to consider negative social influence in decision making processes in early adolescence.
