Although positive parenting behavior is central to efficacious interventions for child conduct problems (CP), studies of youth CP have focused mostly on negative parenting behavior. That is, few studies have examined dimensions of positive parenting behavior (e.g., positive reinforcement, involvement) as independent predictors of CP and even fewer have investigated their potential moderation by callous-unemotional (CU) traits. A sample of 184 6-9 year-old children with and without attention-deficit/hyperactivity disorder (ADHD) was followed prospectively for two years. Controlling for baseline ADHD diagnostic status, initial CP, and negative parenting (i.e., corporal punishment), we examined CU traits, positive reinforcement and involvement, and their interactions as predictors of two-year change in CP. Positive reinforcement and CU traits independently predicted increased rule breaking behavior whereas parental involvement inversely predicted aggressive behavior. A significant positive reinforcement x CU traits interaction suggested that positive reinforcement predicted a decrease in aggressive behavior, but only in children with low CU traits; conversely, positively reinforcement marginally predicted increased aggressive behavior among children with high CU traits. No other significant parenting x CU traits interaction was observed. We consider these findings within a developmental psychopathology framework where interactive exchanges underlie the development of CP.

The 3N model of radicalization proposes that violent radicalization is the result of the contribution of needs, networks, and narratives. Although research has mainly been supportive of this perspective, a substantial amount of ground remains uncovered regarding the network component of the model. Within this framework, we examine why individuals living in certain social environments tend to harbor more positive attitudes toward homegrown terrorism than others. Building on prior research, we hypothesized that individuals living in social environments known to be vulnerable (vs. less vulnerable) are more likely to experience a sense of significance loss (i.e., lack of social integration, perceived conflicts between religious groups), find solace in religious social networks (i.e., mosques), and thus adhere to radical narratives (i.e., legitimization of terrorism). A study with 365 young Muslims from different cities in Spain (Almería, Barcelona, Ceuta, and Melilla)supported these predictions. Theoretical and practical implications for the study of violent extremism are discussed.

The associationbetween fathers' parenting characteristics and their preschool children's social information processing (SIP) patterns is an understudied research topic. Hence, the current study aims to bridge this gap by examining whether there are differences between mothers' and fathers' parenting characteristics and their children's SIP patterns as well as their social functioning in school, with a specific focus on children's aggressive response evaluation and decision (RED) and social difficulties in kindergarten. Using a multimethod (self-reports and direct assessments)multi-informant (mother, father, child, and teacher) design, we collected data from 115 kindergarten children, their mothers, and their fathers, tapping the parents' perceptions of the relationships with the child and parenting style; the child's aggressively biased RED, and the child's social difficulties in kindergarten. We found that fathers' parenting capacities are associated with children's aggressively biased RED, whereas no such associations were found for mothers. In addition, aggressively biased RED mediated the association between fathers' authoritative parenting style and the child's maladaptive behavior in kindergarten. There were no differences between fathers and mothers in relation to social difficulties in kindergarten, with both parents' authoritative parenting style associated with less social difficulties. However, sex moderated this association in mothers as their authoritative style was associated with social difficulties in boys but not in girls. This difference was not found in fathers. On the other hand, fathers' authoritarian parenting style was associated with aggressive RED in boys but not in girls. The tentative nature of these findings and the need for replications are discussed.

This study was aimed at exploring which latent profiles emerge based on ratings of self‐determined motivation to defend victims of bullying, and to explore if they are related to bystander roles and victimization in bullying, as well as student–teacher relations. Data were collected from 1,800 Swedish and Italian students, with an age range between 10 and 18 years (M = 12.6, standard deviation = 1.74). The students completed a survey in their classrooms. Latent profile analysis was used to explore the possible clusters of individuals with similar ratings on the motivational variables. Multivariate analysis of variances were conducted to explore differences between the profiles in relation to their roles when witnessing bullying and to student–teacher relationships. Four latent profiles emerged. The profiles represented respondents (a) high in prosocial motivation, (b) high in externally extrinsic motivation, (c) intermediate in externally extrinsic motivation, and (d) with identified/introjected motivation. Multivariate analyses showed that reports of bystander roles when witnessing bullying, teacher–student relationships, and bullying victimization, significantly differed over the motivational profiles. The bystanders were unevenly distributed across the four groups and most individuals were categorized in the prosocial motivation group. Female and male bystanders were evenly distributed across clusters. The prosocial motivation group experienced victimization to a lesser extent than the other profile groups. Students in the intermediate externally extrinsic group were more likely to take the pro‐bully and outsider role during bullying. Concerning student–teacher relationships, the prosocial motivation group reported the closest relationships with their teachers, while the intermediate externally extrinsic group reported the most conflictual relationships.

The aim of this study was to explore genetic and environmental contributions to laboratory-induced aggressive behavior. On a sample of 478 adult twins (316 monozygotic), the Competitive Reaction Time Task was used for aggression induction. The results showed that the initial, basic level of aggression could be explained by both shared (45%) and nonshared environmental factors (55%), while only nonshared environmental factors (100%) had a significant influence on changes in aggression as provocation increased. Genetic factors had no influence on laboratory-induced aggression. The results highlight the importance of environmental factors in shaping situation-specific aggressive responses to provocation.

Individuals who perpetrate violence may likely perceive violence as appealing and infliction of violence to derive pleasure is termed as appetitive aggression. Individuals who were abducted as children into an armed group often experience a higher number of traumatic event types, that is traumatic load and are usually socialized in a violence-endorsing environment. This study aims to investigate the interaction between age at initial abduction with that of traumatic load, and their influence on appetitive aggression along with perpetration of violent acts by former members of an armed rebel group of both sexes. Semi-structured interviews were conducted among a target group of formerly abducted rebel-war survivors (including participants with and without combat experience) from Northern Uganda. Participants included 596 women and 570 men with N = 1,166 (Mage = 32.58, SDage = 9.76, range: 18-80 years). We conducted robust linear regression models to investigate the influence of age at initial abduction, traumatic load, combat experience, and biological sex on appetitive aggression as well as their perpetrated violent acts. Our study shows, appetitive aggression and the number of perpetrated violent acts were specifically increased in individuals who were abducted young, experienced several traumatic events in their lifetime, and with previous combat experience. For perpetrated violence men showed increased levels whereas for appetitive aggression the association was independent of biological sex. Therefore, early abducted individuals with a higher traumatic load, who have combat experience, need to be given special intervention to prevent any further violence.
