多巴胺系统基因调节青少年同伴拒绝与亲社会行为关系:平行潜增长模型
Dopaminergic genes moderated the association between peer rejection and adolescents'prosocial behavior:Parallel latent growth modeling analyses
摘要
Abstract
Prosocial behaviors—actions intended to benefit others—are critical indicators of adolescents'moral character and social competencies,and form the basis for societal harmony and cooperation.Adolescence is a critical period for facilitating prosocial behavior and internalizing prosocial values attributing to the ecological and biological transitions in this stage.Particularly,peer group changes and the increasing importance of peer relationships during this stage provide both risks and opportunities for the development of prosocial behaviors.In addition,adolescents may exhibit differences in the degree to which they are affected by peer experiences,which are often rooted in their genetic predispositions.Recent evidence indicated that the genes involved in dopamine neurotransmission and metabolism act in an additive manner to influence sensitivity to the environment.However,exploration regarding the dynamic trajectory of the relationship between peer experience and prosocial behavior and whether the dynamic relationship is moderated by dopaminergic genes in a longitudinal framework is still lacking.With the adoption of the multilocus genetic profile score(MGPS)approach,the present study aimed to explore the dynamic trajectory of the relationship between peer rejection and prosocial behavior,and whether the dynamic association was moderated by dopaminergic genes. The participants comprised 1044 adolescents who were followed up at the age of 13～15 years old(mean age 13.32±0.48 years old at Time 1;50.1％females).Adolescents'saliva samples were collected at age 13.Peer-rated prosocial behavior and peer-nominated peer rejection were collected at each time point.All measures presented a good reliability.Real-time genotyping was performed for each participant using MassARRAY RT software version 3.0.0.4 and analyzed using the MassARRAY Typer software version 3.4(Sequenom).The relationship between the developmental trajectories of peer rejection and prosocial behavior and the moderating role of dopaminergic genes was examined via parallel latent growth model and multiple group comparison analyses. The results showed that adolescents'prosocial behavior and peer rejection increased linearly during the follow-up period.Higher initial levels of peer rejection were associated with lower initial levels and slower growth of prosocial behavior.The change rates of peer rejection were associated with the developmental change of prosocial behavior,that is,the slower increase in peer rejection was associated with a greater increase in prosocial behavior over time.In addition,the relationships between the initial level of peer rejection and the initial level and growth in prosocial behavior were moderated by MGPS,with lower MGPS being more sensitive to the initial level of peer rejection. These findings support the dynamic relationship between peer relationships and prosocial behavior and shed light on the complex polygenic underpinnings of the latter.关键词
