Thirty-two sets of monozygotic twins reared apart since shortly after birth (31 pairs and one set of triplets; median age at separation was 0.2 years) were interviewed separately and blindly using the Diagnostic Interview Schedule for presence of DSM-III Axis I psychiatric disorders and antisocial personality. Because the sample was recruited from a nonclinical population, predictably few subje...

The distinctiveness of physical aggression from other antisocial behavior is widely accep­ ted but little research has explicitly focused on young children to empirically test this assumption. A Multitrait­Multimethod Matrix (MTMM) approach was employed to confirm the distinctiveness of physical aggression from nonaggressive antisocial behavior in early childhood. In addition, the convergent va...

Scientific study of genetic contributions to chronic antisocial behavior has stemmed from many lines of research in recent years. Genetic research involving twin, family, and adoption studies have traditionally been used to compare the health and behavior outcomes of individuals who share the same environment or hereditary lineage; several of these studies have concluded that heredity plays som...

Individuals with disorders marked by antisocial behavior frequently show deficits in recognizing displays of facial affect. Antisociality may be associated with specific deficits in identifying fearful expressions, which would implicate dysfunction in neural structures that subserve fearful expression processing. A meta-analysis of 20 studies was conducted to assess: (a) if antisocial populatio...

The concept of bracketed morality has received empirical support in several sport studies (e.g., Bredemeier & Shields, 1986a, 1986b). However, these studies have focused on moral reasoning. In this research, we examined bracketed morality with respect to moral behavior in sport and university contexts, in two studies. Male and female participants (Study 1: N = 331; Study 2: N = 372) completed q...

The purpose of this study was to test direct, additive, and mediation models involving family, neighborhood, and peer factors in relation to emerging antisocial behavior and social skills. Neighborhood danger, maternal depressive symptoms, and supportive parenting were assessed in early childhood. Peer group acceptance was measured in middle childhood, and data on antisocial behavior and social...

This meta-analytic review of 42 studies covering 8,009 participants examines the relation of moral emotion attributions to prosocial and antisocial behavior. A significant association is found between moral emotion attributions and prosocial and antisocial behaviors (d = .26, 95% CI: 0.15, 0.38; d = .39, 95% CI: 0.29, 0.49). Effect sizes differ considerably across studies and this heterogeneity...

The present study examined the role of media use in adolescents’ cyberbullying behaviors. Following previous research, we propose a Cyclic Process Model of face-to-face victimization and cyberbullying through two mediating processes of anger/frustration and antisocial media content. This model was tested utilizing a cross-sectional design with adolescent participants (N = 892). Exposure to anti...

BACKGROUND The relationship between social position and physical health is well-established across a range of studies. The evidence base regarding social position and mental health is less well developed, particularly regarding the development of antisocial behavior. Some evidence demonstrates a social gradient in behavioral problems, with children from low-socioeconomic backgrounds experiencin...
