父母教养与MAOA基因rs6323多态性对学前儿童外化问题的共同作用

采用G×E交互作用的研究范式,以295名学前儿童（M=4.49）和其母亲、父亲作为研究对象,探讨母亲和父亲的教养方式与MAOA基因rs6323多态性对学前儿童外化问题行为的影响。结果发现：母亲、父亲教养方式和MAOA基因多态性对学前儿童外化问题行为的影响存在性别差异,预测男孩外化问题行为时,母亲和父亲教养方式的主效应显著,与MAOA基因多态性的交互作用不显著;在预测女孩外化问题行为时,父亲教养方式的主效应显著,母亲教养方式与MAOA基因多态性的交互作用显著,显著性区域分析发现,携带T等位基因的女孩更容易受到母亲消极教养的不利影响而产生更多外化问题行为,也更容易受到其积极教养的有利影响而减少外化问题行为,这一结果支持差别易感性理论模型。     

父母心理控制和儿童消极情绪性对学前儿童问题行为的共同作用:“素质-压力”还是“差别易感性”

本研究以226名学前儿童和其父母为研究对象,从儿童气质-家庭环境交互作用的视角,采用父母报告的方法收集数据,考察了父母心理控制及儿童消极情绪性对儿童问题行为的共同作用。结果发现：在预测外化问题时,父亲和母亲心理控制的主效应均显著,同时父亲心理控制与儿童消极情绪性的交互作用也显著。显著性区域分析发现,高消极情绪性的学前儿童更易受高父亲心理控制的不利影响,也更易受低父亲心理控制的有利影响,该结果支持差别易感性模型;在预测内化问题时,父亲和母亲心理控制的主效应及其与儿童消极情绪性的交互作用均不显著,说明无论是对高消极情绪性还是低消极情绪性儿童,父母心理控制对其内化问题的影响相对较弱。     

睡眠时间参数对学前儿童问题行为的影响:消极情绪性的调节作用

本研究以338名学前儿童为被试,采用母亲报告法探究了学前儿童睡眠时间与问题行为之间的关系,以及儿童消极情绪性的调节作用。结果发现：（1）睡眠总时长对儿童内化和外化问题行为的主效应显著,而睡眠总时长与消极情绪性对儿童内化和外化问题行为的交互作用不显著;（2）夜间睡眠比对儿童内化问题行为的主效应显著,对儿童外化问题行为的主效应不显著;夜间睡眠比与消极情绪性对儿童内化问题行为的交互作用显著,即对高消极情绪性的儿童,夜间睡眠比能够显著负向预测其内化问题行为,而对低消极情绪性的儿童,夜间睡眠比对其内化问题行为的预测并不显著;夜间睡眠比与消极情绪性对儿童外化问题行为的交互作用不显著。     

COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用

遗传与环境如何交互作用影响儿童青少年的攻击行为是当前攻击研究中的重要前沿课题之一。近年来, 分子遗传学关于人类攻击的研究已拓展到对不同攻击亚类(身体攻击和关系攻击)的遗传基础的探讨。本研究运用问卷法与DNA分型技术, 对1258名儿童进行为时4年(四年级—七年级)的追踪调查, 考察COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用以及性别在其中的调节作用。结果发现, COMT基因rs6267多态性与母亲教养行为仅交互作用于男青少年的身体攻击, 母亲教养行为显著预测GG 基因型男青少年的身体攻击, 但对T等位基因男青少年身体攻击的预测作用并不显著。COMT基因rs6267多态性与母亲教养行为对青少年关系攻击的交互作用不显著。本研究结果表明, 身体攻击和关系攻击具有不同遗传基础和发生机制。     

MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用：素质-压力假说与不同易感性假说的检验

抑郁的遗传与环境交互作用(G×E)机制已成为富有挑战性的前沿课题之一。然而,既有G×E研究大多关注遗传基因与不利环境的交互作用,相对忽视了积极环境的影响。本研究以1025名青少年为被试,运用问卷法与 DNA分型技术,采用间隔3年的追踪设计(T1小学六年级—T2初中三年级),考察 MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用以及性别在其中的调节作用,并同时采用新兴的探索性与验证性方法检验G×E交互作用的素质–压力假说与不同易感性假说。结果显示, MAOA基因rs6323多态性与母亲支持性教养行为交互作用于女青少年的抑郁,母亲支持性教养显著负向预测 GG 基因型女青少年的抑郁,但对 TT基因型女青少年抑郁的预测作用并不显著,该交互作用符合不同易感性假说。MAOA基因 rs6323多态性与母亲支持性教养对男青少年的抑郁无显著交互作用。本研究发现推进了抑郁遗传机制的研究,并为不同易感性假说提供新的研究证据。     

父亲参与教养状况对学前儿童社会技能的作用

作为孩子成长的关键人物之一,父亲对儿童早期的社会性发展具有重要作用。本研究以184名学前中班儿童及其父母为被试,考察父亲参与教养的量(参与教养的时间)和质(积极教养行为)对儿童早期社会技能的作用。结果发现:(1)控制母亲积极教养行为以后,父亲参与教养时间仍显著预测儿童的社会技能,父亲积极教养行为的预测作用不再显著。(2)控制母亲积极教养行为后,父亲参与教养时间显著预测女孩的合作性、责任感、自我控制及总体社会技能,边缘显著预测男孩的主张性;父亲积极教养行为边缘显著预测男孩的主张性,对女孩各项社会技能的预测均不显著。(3)父亲参与教养时间显著预测母亲积极教养水平低组儿童的合作性、主张性、责任感、自我控制及总体社会技能,父亲积极教养行为边缘显著预测母亲积极教养低组儿童的合作性和总体社会技能。表明父亲参与教养对母亲消极教养具有缓冲作用,其中父亲参与教养时间的缓冲效应更明显。     

电视暴力对不同外倾性气质学前儿童社会行为的差异化影响——“一般攻击模型”与“催化剂模型”的理论之争

选取154名3~5岁学前儿童（M=4.11,SD=0.31）,采用母亲报告法收集儿童最近3个月最常观看的电视节目、外倾性气质、问题行为和亲社会行为,对19部儿童最常观看的动画片的暴力性进行编码,考察电视暴力频率和暴力残酷性和儿童外倾性对学前儿童社会行为的共同作用。结果：（1）在预测儿童的问题行为时,电视暴力频率与儿童外倾性的交互作用显著,与低外倾性儿童相比,高外倾性儿童观看较多的电视暴力内容会表现出更多的问题行为,观看较少电视暴力内容也会表现出更少的问题行为,支持差别易感性模型;（2）在预测儿童的亲社会行为时,电视暴力频率和暴力残酷性的主效应及其与儿童外倾性的交互作用不显著,外倾性有显著的预测作用,高外倾性儿童表现出更多亲社会行为。

母亲养育压力与学前儿童社会适应的关系及其性别差异：一项交叉滞后分析

本研究采用交叉滞后的研究设计探讨母亲养育压力与学前儿童社会适应的相互作用关系,选取上海市两所公办幼儿园202名幼儿及其母亲进行为期一年的追踪调查。结果表明：（1）母亲养育压力与男孩的外化问题行为可以相互预测,与女孩外化问题行为相互预测不显著;（2)母亲养育压力与幼儿社会能力可以相互预测;（3）母亲养育压力不能显著预测幼儿内化问题行为,但内化问题可以显著预测母亲养育压力。母亲养育压力与学前儿童社会适应存在相互作用关系,且在幼儿外化问题行为上存在性别差异。

Infant-mother attachment classification: risk and protection in relation to changing maternal caregiving quality

The relations between early infant-mother attachment and children's social competence and behavior problems during the preschool and early school-age period were examined in more than 1,000 children under conditions of decreasing, stable, and increasing maternal parenting quality. Infants' Strange Situation attachment classifications predicted mothers' reports of children's social competence and teachers' reports of externalizing and internalizing behaviors from preschool age through 1st grade. These relations appeared to be mediated by parenting quality; main effects of attachment classification disappeared when effects of parenting quality were controlled. Interactions were also observed. For example, when parenting quality improved over time, teachers rated children with insecure infant-mother attachments lower on externalizing behaviors; when parenting quality decreased, teachers rated insecure children higher on externalizing behaviors. In contrast, children classified as securely attached in infancy did not appear to be affected by declining or improving parenting quality.     

The Association between Positive Parenting and Externalizing Behavior

The present study examined the role of positive parenting on externalizing behaviors in a longitudinal, genetically informative sample. It often is assumed that positive parenting prevents behavior problems in children via an environmentally mediated process. Alternatively, the association may be due to either an evocative gene-environment correlation, in which parents react to children's genetically-influenced behavior in a positive way, or a passive gene-environment correlation, where parents passively transmit a risk environment and the genetic risk factor for the behavioral outcome to their children. The present study estimated the contribution of these processes in the association between positive parenting and children's externalizing behavior. Positive parenting was assessed via observations at ages 7, 9, 14, 24, and 36 months and externalizing behaviors were assessed through parent report at ages 4, 5, 7, 9, 10, 11, and 12 years. The significant association between positive parenting and externalizing behavior was negative, with children of mothers who showed significantly more positive parenting during toddlerhood having lower levels of externalizing behavior in childhood; however, there was not adequate power to distinguish whether this covariation was due to genetic, shared environmental, or nonshared environmental influences.     

Interaction between maternal and paternal parenting styles with infant temperament in emerging behavior problems

This study examined the interaction effects of infant temperament (negative affect, orienting/regulatory capacity, surgency) on the relationship between maternal and paternal parenting styles (authoritative, authoritarian, permissive) and externalizing and internalizing behaviors simultaneously. A diverse sample of mothers (N = 186) and fathers (N = 142) reported on infant temperament of their 6-month-olds and their children’s internalizing and externalizing behaviors one year later. Significant interactions revealed: (a) surgency moderated maternal authoritative and paternal permissive parenting style and externalizing behaviors; and (b) surgency moderated maternal authoritarian and paternal authoritative parenting style and internalizing behaviors. No significant interactions were found between maternal and paternal parenting styles and their report of their infants’ orienting/regulatory capacity and negative affect. Findings suggest interaction effects may appear beginning in infancy.     

The relationship between cognitive abilities and maternal ratings of externalizing behaviors in preschool children

The association between child cognitive abilities and maternal ratings of child externalizing behaviors was investigated in a randomly selected sample of 290 preschool children. Child cognitive abilities were assessed by the WPPSI-R, whereas mothers completed the Yale Children's Inventory for the assessment of child externalizing behaviors. Maternal education, and maternal child-rearing style, as defined by scores on the Child Rearing Practices Report, was significantly related to perceived externalizing child behavior. Hierarchical regression analyses revealed that for girls, low child IQ remained a significant predictor of perceived externalizing behavior when effects of maternal education and child-rearing style were controlled for (p < 0.01). Maternal child-rearing style made independent contributions to explaining variance in girls' and boys' behavior score. The results are discussed in terms of differential gender socialization practices and gender stereotypes.
