Abstract

Despite the well-established relationship between parenting and child aggression, the mechanisms by which children incur this risk and whether genetic sources contribute to the heterogeneity in their vulnerability are not entirely clear. This study utilized a longitudinal sample of adolescents (n = 1,047, 50.2% females, Mage = 13.32 ± 0.48 years at Time 1) to examine the effects of positive and negative parenting on aggression, as mediated by inhibitory control and moderated by the serotonin receptor 2A (5-HTR2A) haplotype. Mediation analysis revealed that inhibitory control indirectly mediated the link between both positive and negative parenting and overt aggression but not relational aggression. Further, the indirect effect of negative parenting on overt aggression via inhibitory control was moderated by the 5-HTR2A haplotype. Compared to adolescents carrying zero copies of Thymine-Thymine haplotype, those with one copy of Thymine-Thymine haplotype had better inhibitory control when experiencing less negative parenting, which buffers the risk for overt aggression. However, the mediating role of inhibitory control did not hold in the positive parenting model. These findings elucidate the manner by which adolescents with different genetic predispositions develop aggressive behaviors in the context of family and suggest different etiology of overt and relational aggression.

养育行为、抑制控制和攻击行为:血清素受体 2A 单倍型的调节作用。
尽管养育方式与儿童攻击性之间的关系已得到证实,但儿童产生这种风险的机制以及遗传因素是否导致了儿童易受攻击性的异质性,目前尚不完全清楚。本研究利用一个青少年纵向样本(n = 1,047,50.2% 为女性,年龄 = 13.32 ± 0.48 岁(时间 1)),研究了积极和消极养育方式对攻击行为的影响,这些影响由抑制性控制和血清素受体 2A (5-HTR2A) 单倍型调节。中介分析表明,抑制控制间接中介了积极和消极养育方式与公开攻击行为之间的联系,但不中介关系攻击行为。此外,5-HTR2A单倍型还调节了消极养育通过抑制控制对明显攻击行为的间接影响。与胸腺嘧啶-胸腺嘧啶单倍型为零拷贝的青少年相比,胸腺嘧啶-胸腺嘧啶单倍型为一个拷贝的青少年在经历较少的负面养育时具有更好的抑制控制能力,从而缓冲了公开侵犯的风险。然而,在积极养育模式中,抑制控制的中介作用并不成立。这些发现阐明了具有不同遗传倾向的青少年在家庭背景下发展攻击行为的方式,并提出了公开攻击和关系攻击的不同病因。(PsycInfo Database Record (c) 2024 APA, 版权所有)。
