留守初中生同伴侵害与攻击性的关系:链式多重中介模型

为探究留守初中生同伴侵害与攻击性的关系机制,通过构建链式多重中介模型,考察歧视知觉、孤独感和心理韧性在二者关系中的多重中介效应。采用问卷调查法对519名留守初中生进行调查,结果显示：（1）留守初中生同伴侵害的发生率为96.3%,具有普遍性;（2）留守初中生同伴侵害、歧视知觉、孤独感、心理韧性与攻击性之间均呈显著相关;（3）留守初中生的歧视知觉、孤独感和心理韧性在其同伴侵害与攻击性的关系中具有链式多重中介作用;（4）同伴侵害与攻击性关系模型具有一定稳定性,同时在是否留守及单亲与双亲外出留守初中生群体中存在显著差异。研究结果揭示了同伴侵害与攻击性的关系机制,可为探索留守初中生不良同伴关系的教育策略提供参考。     

青少年早期同伴侵害的亚类别及其稳定性:个体定向的分析

以山东省济南市12所初中的2015名初一学生为被试,对其持续追踪至初二年级,采用自我报告法测查青少年的同伴侵害、受欺负和社交退缩,采用同伴提名法测查青少年的攻击行为。采用潜在剖面分析和潜在转变分析,探讨青少年早期同伴侵害的亚类别以及各亚类别中青少年受侵害身份的稳定性与发展变化。结果发现：（1）同伴侵害亚类别可以分为：未受侵害组、低受侵害组、中等受侵害组和高受侵害组四类,各亚类别间的异质性主要体现在受侵害程度上;（2）中等受侵害组和高受侵害组表现出高水平的攻击行为和社交退缩,且高受侵害组的社交退缩行为更多;（3）青少年早期个体的受侵害身份具有中到高水平的稳定性,同时也存在着一定的发展变化,主要表现为高受侵害组青少年倾向于向中等受侵害组转变,中等受侵害组青少年倾向于向低受侵害组转变。攻击行为是受侵害身份转变的重要预测因素。     

Just banter? Friendship,teasing and experimental aggression in adolescent peer networks

Aggressive behaviour serves many useful social functions, yet can also have damaging consequences. In line with evidence showing adolescent development in social cognitive abilities, we hypothesized that the use of aggression would become more sophisticated with age. We investigated adolescent aggression towards peers using an experimental, hypothetical aggression paradigm, the hot sauce paradigm, in a school‐based social network setting. Participants (N = 162 aged 11–17, 98 male) indicated which strength of imaginary hot sauce they would allocate to each of their classmates. A Social Network Questionnaire quantified participants’ perceived dyadic social tie strength with each classmate, and the incidence of mutual or unilateral dyadic real‐world aggression (e.g. teasing). Participants allocated weaker hot sauce to peers with whom they reported strong, positive social ties and an absence of self‐reported unilateral real‐world aggression. With increasing cross‐sectional age, there was a decrease in the impact of social tie strength and an increase in the extent to which hot sauce allocation was predicted by self‐reported mutual real‐world aggression. This pattern of findings is consistent with young (vs. late) adolescent use of experimental, hypothetical Hot Sauce aggression to reflect real‐world animosity, while late adolescents’ behaviour is more subtle. These findings extend our understanding of the dyadic social context of adolescent aggressive behaviour using a novel experimental aggression paradigm.     

青少年早期身体攻击与关系攻击的异质性共发模式、稳定性及其与同伴关系的联系

采用整群抽样法选取1967名青少年被试（平均年龄13.22±0.36岁,男生1018人）进行三年追踪,运用个体定向方法考察青少年早期身体攻击和关系攻击的异质性共发模式及其稳定性、与同伴关系间联系。结果发现三时间点均存在5个身体—关系攻击共发模式组：高身体—关系攻击组、中等身体—关系攻击组、中下身体且低关系攻击组、低身体且中下关系攻击组、低身体—关系攻击组,表明两类攻击总体上表现出水平一致或类似的共发模式,且具跨年龄一致性。各共发模式身份表现出有差异的跨时间稳定性,低攻击组稳定性最高,其次是高攻击组、中等攻击组,低身体且中下关系攻击组转变概率最高。高攻击组同伴拒绝水平最高、同伴接纳最低,低攻击组反之,其他组同伴拒绝水平均显著高于低攻击组,为两类攻击亚组共发模式提供了效度证据。     

青少年的同伴选择与同伴影响：基于学业投入与学业成就的纵向社会网络分析

以756名中学生为研究对象,对学业投入、学业成就、同伴团体进行追踪测量,探讨青少年同伴团体的学业投入及学业成就是否存在同伴选择与同伴影响效应。结果表明：（1）在1年的追踪时间中,青少年学业投入的发展呈下降趋势,初始水平与下降速度负相关,学业成就的发展呈上升趋势,初始水平与上升速度无显著相关;（2）学业投入与学业成就存在同伴选择效应,青少年倾向选择与自己学业投入及学业成就相似的个体构建同伴团体;（3）青少年的学业投入及学业成就与同伴逐渐趋近相似,即同伴影响效应显著。     

Is indirect aggression typical of females? gender differences in aggressiveness in 11- to 12-year-old children

Gender differences regarding aggressive behaviour were investigated in 167 school children, 11 to 12 years of age, through peer-rating techniques supported by self-ratings and interviews. The social structure of the peer groups also was studied. The principal finding was that girls made greater use of indirect means of aggression, whereas the boys tended to employ direct means. Gender differences in verbal aggression were less pronounced. The social structure of peer groups was found to be tighter among girls, making it easier for them to exploit relationships and harm their victims by indirect manipulative aggression. Because indirect aggression has rarely been satisfactorily studied with tests of aggression, this finding may help to explain 1) the generally lower correlation found between peer-rated and self-rated aggression in girls than among boys (indirect means not being so readily recognized by the subject as a kind of aggression) and 2) the low stability of aggressiveness in girls often found in developmental studies.     

Aggressive Behavior and Peer Social Status of Elementary School Children

The relation between aggression and peer social status was investigated in a group of 238 third-through fifth-grade children. Peer social status refers to the degree to which a child is accepted by his or her peer group. By asking children to nominate peers they “like most” and “like least,” one can identify children who are popular, rejected, neglected, or viewed as average within their peer group. Results indicated low to moderate correlations between peer-nominated aggression and global indices of social acceptance. More specifically, it was found that aggressive children largely comprised the rejected and average social status groups, but not the popular or neglected groups. Furthermore, analyses indicated that according to both peers and teachers, aggressive/rejected children showed academic and social-skill deficits, whereas aggressive children of average peer status exhibited adequate adjustment similar to that of nonaggressive/average-status children. These results suggest the importance of considering peer social status when identifying aggressive children in need of intervention and in determining which skill deficits to address. In addition, knowledge of an aggressive child's peer status might be useful in enhancing the predictability of adult adjustment.     

A multisource exploration of the friendship patterns of children with and without learning disabilities

Friendship patterns of 117 children with learning disabilities (LD) and 115 children without LD in Grades 4–8 were examined. In comparison with children without LD, boys with LD had fewer mutual friends, children with LD had more friends with learning problems and more younger friends, and children with LD in Grades 4–6 had less stable relationships. With regard to friendship quality, children with LD reported higher levels of conflict, lower levels of validation, and more problems with relationship repair than did children without LD. The findings were discussed in terms of factors that have been found to enhance friendship such as proximity and similarity, and the social skills difficulties that have been associated with learning disabilities.     

Patterns of friendship among girls with and without attention-deficit/hyperactivity disorder

Examined patterns of friendship participation, stability, and quality among previously unfamiliar, ethnically diverse girls with attention-deficit/hyperactivity disorder (ADHD; n = 140) and comparison (n = 88) girls, aged 6–12 years, who attended 5-week naturalistic summer camps. Each girl completed sociometric nominations during Weeks 1, 3, and 5 of the camps; friendships were indexed by examining patterns of reciprocal nominations. At each assessment point, girls with ADHD had fewer mutual friends and were more likely to have no friends. Girls with Combined-type ADHD exhibited difficulties maintaining friendships from the beginning to middle of camp, whereas girls with Inattentive-type ADHD demonstrated poor friendship stability from the middle to end of camp. In general, girls with ADHD had higher levels of negative relationship features—including conflict and relational aggression—than did comparison girls, but levels of positive relationship features did not differ across subgroups. Friendship status predicted positive and negative peer regard, controlling for Verbal IQ and diagnostic status. Overall, although girls with ADHD were able to make friends to some extent, they differed from comparison girls in terms of the likelihood of doing so, the ability to maintain the friendships that they did form, and the levels of negative features found in their friendships.     

The Roles of Ethnicity and School Context in Predicting Children's Victimization by Peers

This study examines the prevalence, stability, and contextual correlates of peer victimization in a sample of African-American, Hispanic, and non-Hispanic White urban elementary school-age children. A total of 1956 children (40% African-American, 42% Hispanic, and 18% White) attending any 1 of 14 public elementary schools located in one large and one mid-sized Midwestern city participated in this study. Peer ratings of victimization were obtained at two points in time, separated by a 2-year period. Findings revealed that risk for being victimized by peers varied by ethnicity and by school context. Hispanic children had lower victimization scores than did either African-American or White children. These findings, however, were moderated by school context, such that attending ethnically integrated schools was associated with a significantly higher risk of victimization for White children and a slightly lower risk of victimization for African-American children and did not affect the risk of victimization for Hispanic children. In addition, African-American children were less likely than Hispanic and White children to be repeatedly victimized by peers over time. The importance of considering ethnicity and context in explaining peer victimization is discussed and suggestions for preventive interventions and future research are provided.
