Collective motivation beliefs of early adolescents working in small groups

This study examined collective efficacy, group cohesion, and group performance in 125 randomly assigned groups of older (mean age 13.45 years) and younger (mean age 11.41 years) early adolescents working on three cooperative tasks. Collective motivation significantly predicted performance, even after controlling for past performance and self-efficacy for the older but not the younger participants. For the older (but not the younger) participants, groups with high collective efficacy and group cohesion scored higher on performance tasks than groups with low collective efficacy and group cohesion. The results point to the emergence of collective motivation beliefs in early adolescence, consistent with theories of social and cognitive development. Implications for theory and suggestions for future research are discussed.     

The Multidimensional Nature of Social Cohesion: Psychological Sense of Community, Attraction, and Neighboring

Items from the Neighborhood Cohesion Instrument were completed by 1,732 individuals from a random sample of households in 20 rural communities across Canada during the summer of 2001. Confirmatory factor analysis of the NCI items based on polychoric correlations and weighted least squares estimation found three underlying latent variables. Although items were related to the three latent variables in a somewhat different manner than they were in Buckner's original study, the same three latent variables were evident, providing convincing evidence that social cohesion has at least three subscales: psychological sense of community, neighboring, and attraction. Correlations between subscales were relatively high (between .67 and .87). Intraclass correlation coefficients for the three scales were .115, .127, and .112. In addition, the community means differed on different subscales in a manner that related to recognized characteristics of the communities. Thus the subscales are appropriate measures for both individuals and communities and can be recommended for further research on social cohesion.     

Mergers and group status: the impact of high,low and equal group status on identification and satisfaction with a company merger,experienced controllability,group identity and group cohesion

Although mergers are seen as tools to enhance business in today's global marketplace, they have had a low success rate, possibly because the focus has been on financial and legal issues rather than on the human factors involved. In this respect, focusing on the social psychological variables, social identity theory can provide an explanation for the failure of most mergers. An experiment based on this theory involving mergers between two workgroups was conducted to investigate the effects of merger‐related status on participants' psychological responses to the mergers. Thirty‐six small groups were assigned to three different status groups (high, low and equal status groups) using the minimal group paradigm. Most negative responses to the merger—in terms of identification with the merger group, satisfaction with the merger, common in‐group identity, group cohesion and controllability—were given by the members of the low status groups. Contrary to expectations, status was not related to the performance of the groups. Theoretical and practical implications are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Neighborhood Types and Externalizing Behavior in Urban School-Age Children: Tests of Direct, Mediated, and Moderated Effects

We evaluated the association of neighborhood types and externalizing behavior problems in 99 predominately African-American urban children (M = 10.7 years), and the extent to which qualities of the family environment mediated or moderated these associations. Three distinct neighborhood types were identified using cluster analysis of census and crime data. Results showed that children living in very poor neighborhoods with moderate crime levels had more behavior problems than children living in relatively low crime, low poverty areas. Family stress mediated the association between neighborhood type and behavior problems. Family cohesion moderated the association of neighborhood type and adjustment: children living in the most impoverished neighborhoods with high levels of family cohesion demonstrated fewer behavior problems relative to their peers in low-cohesive households in the same area, and similar levels of behavior problems relative to children in highly cohesive homes in low crime, low poverty areas.     

COMT基因rs6267多态性与青少年期亲子亲合与冲突的关系：性别与父母教养行为的调节作用分析

采用基因－环境设计, 以208名初中生为被试, 系统考察COMT基因rs6267多态性与青少年期亲子亲合与冲突的关系, 以及性别与父母教养行为在其中的调节作用。结果显示rs6267多态性对亲子关系无显著主效应, 但其与亲子亲合、母子情绪冲突的关联模式在男女青少年群体中相反; rs6267多态性与父母积极教养行为对亲子关系无显著交互作用, 但其与母亲消极教养行为对母子冲突具有交互作用趋势。     

Investigating the Potentially Protective Effects of Neighborhood Processes in Intimate Partner Violence

Women who experience intimate partner violence (IPV) are often mothers. This study seeks to further the understanding of IPV in families, as well as social factors that can prevent violence from occurring. Based on existing literature and theory, we hypothesize that social cohesion and informal social control are associated with lower rates of IPV. To test this theory, we use a total sample of 2,344 mothers with partners surveyed in the Families and Child Wellbeing study and analyze the effects of neighborhood social cohesion and informal social control on reported IPV experiences. This was done by using a negative binomial regression. Findings show that informal social control is associated with lower levels of IPV experiences among mothers with partners.     

亲子关系对青少年冒险行为的影响:有调节的中介模型

为探讨亲子关系对青少年冒险行为的影响机制,采用亲子关系问卷、同伴群体特征问卷及冒险行为问卷对山东省日照市三所普通中学的1275名初一到高三学生进行调查。结果发现：（1）父母支持与亲子冲突、不良同伴交往及冒险行为均呈负相关,亲子冲突与不良同伴交往、冒险行为均呈正相关,不良同伴交往与冒险行为呈正相关;（2）父母支持显著负向预测冒险行为,亲子冲突显著正向预测冒险行为,且两者的预测作用都可以通过不良同伴交往的中介作用实现;（3）在亲子冲突影响冒险行为这一模型中,不良同伴交往起中介作用,且中介的后半路径受性别调节,具体表现为：与女生相比,男生结交不良同伴会参与更多冒险行为。结果提示,不良亲子关系和不良同伴交往都是青少年冒险行为的重要预测因素,且不良亲子关系可以通过影响同伴交往影响青少年冒险行为。此外,在这一过程中,存在性别差异,当亲子冲突较多时,尤其应当关注男孩的同伴交往情况。
