“…Reduced gray matter in the prefrontal region is associated with aggressive behaviors regardless of diagnosis of psychological disorder, and this suggests that aggression is affected by biological factors since many genetic factors come into play in the gray matter of the frontal cortex [ 27 ]. A long-term twin follow-up study showed that genetic factors play a major role in social aggression [ 28 , 29 ].…”

“…The effect of environmental factors on aggression varies depending on gender, with females affected relatively less by the environment [ 29 ]. To investigate the differences in the mediating effect of father-child communication on the association between aggression and the risk of IGD, a multi group structural equation model stratified by gender was analyzed.…”

OBJECTIVESOpen and supportive communication between parents and children is known to reduce adolescents’ delinquent behavior. Recently, the risk of Internet gaming disorder (IGD) has been increasing in adolescents. The purpose of this study was to investigate the mediating effects of parent-child communication styles on the relationship between adolescent aggressiveness and risk of IGD.METHODSParticipants in this study were 402 first-year students from 4 middle schools in Seoul who enrolled in the Internet user Cohort for Unbiased Recognition of gaming disorder in Early adolescence (iCURE) and completed baseline assessment in 2016. The structural equation model was constructed based on an aggression questionnaire, the Internet game use-elicited symptom screen, a mother-child communication inventory, and a father-child communication inventory.RESULTSAdolescents’ aggressiveness was found to be related to their risk of IGD. The father-child communication style mediated the relationship between aggression and risk of IGD. However, the mother-child communication style had no mediating effect.CONCLUSIONSOur findings suggest that fathers should make an effort to improve open and positive communication skills with their children, because the father-child communication style plays an important role in the relationship between adolescent aggressiveness and risk of IGD.

“…Social aggression is especially interesting in this regard, as it varies only minimally across sex (but may be slightly more common in girls; Card, Stucky, Sawalani, & Little, 2008). Ongoing work in the MSUTR sample has also found no evidence of sex differences in the etiology of social aggression, for either maternal or teacher informants (Slawinski, Klump, & Burt, 2018). Although these findings require replication, they suggest that the current findings for teacher informant-reports do not extend to all antisocial phenotypes.…”

Are there sex differences in the etiology of youth antisocial behavior?

Sex differences in the etiology of youth antisocial behavior are an intuitively appealing hypothesis given the consistently higher prevalence of antisocial behavior in boys versus girls. Although a few early studies supported this possibility, reporting stronger genetic influences in females and stronger environmental influences in males, subsequent meta-analyses found that antisocial behavior was equally heritable in males and females. Critically however, none of the meta-analyses evaluated whether sex differences in etiology might be enhanced in particular subpopulations or contexts. The current study sought to do just this. We examined 1,030 child twin pairs from the Michigan State University Twin Registry, half of whom were oversampled for neighborhood disadvantage, thereby allowing us to meaningfully evaluate whether sex differences in etiology were enhanced in disadvantaged contexts. We also directly evaluated the possibility of sex differences in the etiology of teacher- versus maternal-informant reports of antisocial behavior, evaluating each informant-report for possible sex differences. Results were not consistent with differential effects of sex on etiology in disadvantaged versus advantaged contexts, but did suggest moderation by informant-report. Namely, genetic influences were stronger in girls, and environmental influences were stronger in boys, when antisocial behavior was assessed using teacher informant-reports, but not when assessed using maternal informant-reports. Critically, these findings were confirmed when we reanalyzed meta-analytic data from Burt (2009a) separately by informant. Such findings suggest that, at least in school contexts, the etiology of antisocial behavior does indeed vary across sex. Implications are discussed. (PsycINFO Database Record

“…However the influence of genes can be augmented by the environment such that it decreases with decreasing positive social feedback [ 37 ] or increasing parental negativity [ 38 ]. From the genetic influences, mainly additive genetic factors have been found to explain the variability; they accounted for 15-77% of the variance in social aggression [ 39 ] and up to 90% of the individual differences in baseline impulsive aggression in the longitudinal Quebec Newborn Twin Study [ 40 ]. Interestingly, the effects of genetic factors on aggressive behaviors can change over time [ 41 ] and the influence of genes on the variation of aggressive behaviors can change over development (18% genetic influence in early-middle adolescent to 47% genetic influence in middle adolescent) [ 42 ].…”

Excessive and persistent aggressiveness is the most common behavioral problem that leads to psychiatric referrals among children. While half of the variance in childhood aggression is attributed to genetic factors, the biological mechanism and the interplay between genes and environment that results in aggression remains elusive. The purpose of this systematic review is to provide an overview of studies examining the genetics of childhood aggression irrespective of psychiatric diagnosis. PubMed, PsycINFO, and MEDLINE databases were searched using predefined search terms for aggression, genes and the specific age group. From the 652 initially yielded studies, eighty-seven studies were systematically extracted for full-text review and for further quality assessment analyses. Findings show that (i) investigation of candidate genes, especially of MAOA (17 studies), DRD4 (13 studies), and COMT (12 studies) continue to dominate the field, although studies using other research designs and methods including genome-wide association and epigenetic studies are increasing, (ii) the published articles tend to be moderate in sizes, with variable methods of assessing aggressive behavior and inconsistent categorizations of tandem repeat variants, resulting in inconclusive findings of genetic main effects, gene-gene, and gene-environment interactions, (iii) the majority of studies are conducted on European, male-only or male-female mixed, participants. To our knowledge, this is the first study to systematically review the effects of genes on youth aggression. To understand the genetic underpinnings of childhood aggression, more research is required with larger, more diverse sample sets, consistent and reliable assessments and standardized definition of the aggression phenotypes. The search for the biological mechanisms underlying child aggression will also benefit from more varied research methods, including epigenetic studies, transcriptomic studies, gene system and genome-wide studies, longitudinal studies that track changes in risk/ameliorating factors and aggression-related outcomes, and studies examining causal mechanisms.
