The relationship between positive parenting and adolescent prosocial behaviour: The mediating role of empathy and the moderating role of the oxytocin receptor gene

Abstract

Prosocial behaviour, that is, behaviour intended to benefit others, has been linked to a variety of desirable traits, including positive relationships, better academic performance and lower levels of antisocial behaviours. As such, the origins and the mechanisms underlying the remarkable individual differences in prosocial behaviour are the focus of an increasing number of studies, with numerous research consistently documenting the important role of positive parenting and empathy. Notably, differentiating between cognitive and emotional components of empathy may help further clarify the processes by which parenting eventuates in prosocial behaviour. Although all children may be impacted by parenting, some children benefit more than others from good-quality rearing. Recent research has suggested that the oxytocin receptor ( OXTR ) gene rs53576 polymorphism could determine the degree to which a child is influenced by environment. The biological function of rs53576 polymorphism has yet to be delineated, and the literature is mixed with regard to heterozygote (AG) grouping; thus, the implications for AG grouping are not well understood. Therefore, the dummy coding, additive coding, dominant coding and recessive coding models were all investigated in this study to test the nature of gene effect. This study aimed to extend previous studies on the association between parenting and prosocial behaviour by examining the mediating role of cognitive and emotional empathy and the moderating role of the OXTR gene. The participants were 1082 mother–offspring dyads (adolescents’ mean age: 12.32 ± 0.48 years, 50.3% females) recruited from the community. At Time 1, mothers reported their positive parenting via the Chinese version of the Child-Rearing Practices Report (CRPR) and peer-rated adolescents’ prosocial behaviours. At Time 2, adolescent-reported perspective-taking and empathic concern, peer-rated prosocial behaviours and saliva samples were collected. All measures showed good reliability. Genotyping at OXTR gene was performed with MassARRAY
