The purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high-risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low-income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high-risk sample from the development of externalizing behaviors. 相似文献

本研究拟探讨社会排斥对大学生网络偏差行为的影响及其作用机制——自我控制的中介作用和道德同一性的调节作用。对769名大学生问卷调查的结果表明:(1)社会排斥与网络偏差行为呈显著正相关,与自我控制呈显著负相关;自我控制和道德同一性均与网络偏差行为呈显著负相关;(2)社会排斥对网络偏差行为具有显著的正向预测作用,且自我控制在这一关系中具有显著的中介作用;(3)社会排斥对网络偏差行为的直接预测作用以及自我控制的中介作用均受到道德同一性的调节,且这两种效应在道德同一性水平较低的群体中都更为显著。本研究不仅有助于进一步明晰网络偏差行为的影响因素及其发生机制,而且对大学生网络偏差行为的预防和干预还具有一定的实践指导价值。 相似文献

The present research aimed to investigate specific behaviors of professional urban bus drivers in China with the revised Driver Behavior Questionnaire (DBQ), and to define the relationships among various driving behaviors (errors, positives, inattention errors, violations), background information (age, years of driving experience, mobility, etc.), self-assessment, and traffic accident. To achieve such goals, the present research designed a four-dimensional DBQ with 20 items for professional urban bus drivers in China. The KMO coefficient of the whole scale was 0.835, and Bartlett’s test was statistically significant (p < 0.000), which demonstrated strong validity of the scale and should be suitable for factor analysis. The four loading factors accounted for 58.991%. In addition, the reliability and effectiveness of the present 20-item scales were measured. The coefficient of internal consistency-Cronbach’s alpha coefficient was 0.881 and the Cronbach’s Alpha Based on Standardized Items was 0.911. This showed that driving behavior scale of professional bus drivers in China was of high reliability and validity. The analysis showed that among the four factors, positive driving behaviors were significantly associated with errors, inattention errors and violations, respectively. Errors, inattention errors and violations correlated positively with each other. This verified that the correlation coefficient of each factor was medium and high, which indicated that the scale had good difference validity. The test content of the total scale was also highly consistent with the test content of each factor, which indicated that the revised scale had good standard related validity. According to the accident prediction model, the variables that significantly affected the occurrence of traffic accidents were daily driving time, positive driving behavior, SE2 (Driving safety), SE3 (Aberrant driver behaviors). The results showed that professional bus drivers often working overtime were most likely to have accidents. The probability of traffic accidents decreased by 53% for every unit of positive driving behavior frequency of professional bus drivers. The more they felt that they had the tendency of aberrant driving behavior, the more likely they were to have traffic accidents. To summary, the present research contributed to validating and improving the DBQ for professional urban drivers in China. 相似文献

The present study investigated differences in driver aggression for self and others within countries and cultural differences between driver aggression, aberrant, and positive driver behaviors across five countries (Estonia, Greece, Kosovo, Russia, and Turkey). It was predicted that drivers from these five countries differ significantly in terms of driver aggression for self and others, aberrant, and positive driver behaviors. In the study, 743 participants completed the questionnaire package, including the Driver Aggression Indicators Scale (DAIS), the short version of the Driver Behavior Questionnaire (DBQ) with items from the Positive Driver Behavior Scale, and the Demographic Information Form. Paired samples T-tests were conducted to examine the differences in driving aggression between self and others in the five countries. The results indicated that, except for Russian drivers, drivers reported that other drivers had higher driver aggression than themselves. To examine the cross-cultural differences, analysis of covariance (ANCOVA) tests were conducted for the two dimensions of the DAIS (hostile aggression and revenge, and aggressive warnings) and the three dimensions of the DBQ with items from the Positive Driver Behavior Scale (errors, violations, and positive driver behaviors). Cross-country item-based comparisons were then made for the DAIS and the DBQ. The ANCOVA results showed significant differences in both item-based and subscale comparisons. Russian drivers were significantly different from other drivers in terms of hostile aggression and the revenge subscales of the DAIS and positive driver behaviors. Turkish drivers were significantly different from other drivers in several items of the DBQ, including errors and violations. The findings suggest that culture-specific strategies might be conducted for traffic-related anger management. Furthermore, differences in errors and violations among the five countries may be due to cultural differences. Positive driver behaviors might be better promoted in countries by drawing on their distinct cultural road safety strategies. 相似文献

产后抑郁症是指女性分娩后一段时间内出现的严重抑郁发作现象。研究表明, 催产素不仅参与分娩过程和正常的母性行为表达, 也在调节产后抑郁的发病及患者的母性行为中起到了重要的作用。产后抑郁症患者的情绪和认知功能受损, 这可能导致了母性行为表达质量的下降; 催产素可以通过中脑边缘多巴胺系统来调控母性行为, 作用于内侧视前区(MPOA)来激活中脑腹侧被盖区(VTA)-伏隔核(NAc)环路从而影响伏隔核内多巴胺的分泌; 催产素对产后抑郁症中母性行为的调节机制可能是通过调节五羟色胺系统的功能来发挥抗焦虑作用, 也可能是通过与其它激素的交互作用来加速母性行为的表达。未来研究进一步明确催产素在中枢神经环路中的功能差异, 以及社会支持对产后抑郁症患者催产素的使用带来的影响。 相似文献

Recent theoretical discussion of the influence of between- and within-culture factors on social behaviors suggests that both approaches may be useful. The present study was designed to investigate the joint influence of sociocultural (between-group) and individual (within-group) factors on resource allocation preferences. Brazilian (n=166) and European–American (n=99) children with ages ranging from 37 to 140 months were administered a resource allocation task, which consisted of distributing rewards to themselves or to an acquaintance. As expected, individualistic resource allocation preferences decreased with age, whereas competitive and cooperative resource allocation preferences increased with age. Culture group, the task-specific cognitive demands, and the gender of the child, however, moderated these age differences. For example, gender differences in resource allocation preferences were stronger among Brazilians as compared to European–Americans and stronger in the reduced cognitive demand condition. Models of cooperative and competitive behaviors that consider the role of culture group, gender, and cognitive development and applied implications are discussed. 相似文献

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。 相似文献
