大学生友伴选择标准及其友伴关系

从湖南两所大学选取297名大学生为被试,采用定性研究的方法探讨大学生友伴选择的影响因素,并制定友伴选择标准调查问卷,然后再从湖南一所大学选取1166名大学生为被试,采用定量研究的方法对大学生友伴选择标准及其友伴数量、友伴关系质量之间的关系进行调查。结果发现:大学生在友伴选择标准方面可以归为完美型、适度型和低要求型3种类型;不同类型在性别、年级、专业上的分布存在显著差异;适度型大学生的友伴数量显著多于完美型;完美型、适度型大学生在与友伴的帮助与支持、与友伴的冲突方面显著多于低要求型,完美型在与友伴的冲突强度上也显著大于低要求型。     

友伴对青少年吸烟和饮酒行为的影响

本研究从北京市几所中小学选取小六、初二和高一学生1040名来探讨友伴对青少年吸烟饮酒行为的影响。研究采用无记名问卷测查的形式,先让被试提名一个最要好友伴和九个一般友伴,再回答自己曾经是否吸烟饮酒和吸烟饮酒的程度。分析时,只对在被试范围内的友伴进行统计。结果发现,无论男女和年级,被提名的友伴中,吸烟饮酒的友伴人数有较大差别;男生友伴中吸烟饮酒的友伴明显超过女生;高年级学生友伴中吸烟饮酒的友伴明显多于低年级学生;友伴的吸烟饮酒行为和吸烟饮酒程度对青少年的吸烟饮酒行为有明显影响;友伴中吸烟饮酒的人数多少也与青少年吸烟饮酒行为有直接的关系;但单双向友伴关系对青少年的吸烟饮酒行为无明显影响。     

不同年级青少年的友伴网络结构

选择小六、初二和高一学生共１０４０名作被试,采用十项友伴提名法,要求被试至多提名１０个友伴,通过网络分析,从友伴提名数、友伴选择的双向性两个方面探讨不同年级学生友伴网络结构,结果显示,青少年平均拥有６～７个友伴,在这些友伴关系中,单向选择占明显的优势。性别、年级和学习成绩之间的交互作用以及父母受教育水平和家庭结构之间的交互作用（包括两两之间的交互作用）除个别外,均不明显;性别、年级和学习成绩的主效应较明显,而父母受教育水平和家庭结构的主效应却不明显。     

感知的和实际的友伴吸烟行为对青少年吸烟行为的影响

选取北京市一所普通中学和一所重点中学初一至高三的学生为被试,采取自由参与研究和被试自我报告、被试报告友伴、友伴自我报告吸烟行为的方式,从认知发展理论的角度出发,探讨感知的与实际的友伴吸烟行为对青少年吸烟行为的影响。结果验证了认知发展理论,即感知的友伴吸烟行为对青少年吸烟行为具有明显的影响作用,而实际的友伴吸烟行为没有明显的影响作用。研究还发现,性别和友伴关系类型对感知的与实际的友伴吸烟行为之间的差异存在明显的主效应;友伴自我报告的吸烟行为超过被试自我报告的吸烟行为。讨论揭示了研究结果对预防和干预青少年吸烟行为的意义。     

友伴人际品格对儿童人际品格的影响:友伴数量的调节作用及儿童群体差异

友伴是儿童发展的重要影响源。本研究从儿童积极发展的视角探讨友伴人际品格（仁慈和公正）对儿童人际品格的影响及友伴数量在其中的调节作用,并检验了儿童的群体（学段、性别、是否独生）差异状况。研究采用班级同伴提名法及儿童品格调查问卷对1555名4~9年级儿童及其互提名友伴展开调查。结果发现：（1）友伴仁慈和公正显著预测所有儿童群体的仁慈和公正;（2）儿童的友伴数量更多时,友伴公正对其公正的预测作用更显著;该调节效应仅体现在初中生和男生群体上。研究结果表明,儿童与具有积极品格特征的友伴交往对其积极品格的发展至关重要,且对于特定群体（如初中生、男生）,与越多具有积极品质的友伴交往,其受到的积极影响越大。     

友伴网络结构与中学生的吸烟行为

运用社会网络理论和分析技术考察友伴网络结构与中学生吸烟行为的关系。被试选自北京两所中学1091名初一至高三学生,要求他们最多提名10名友伴,并报告自己及其友伴的吸烟行为。然后,使用NEGOPY社会网络分析软件对中学生的友伴网络结构进行分析。研究结果表明,中学生的友伴网络结构存在团体成员、团体联系者和孤立者三种类型,团体成员所占比例超过团体联系者和孤立者,但随年级升高,团体成员有下降趋势。此外,团体成员的吸烟率显著低于孤立者和团体联系者,即使排除性别、年龄和学校类型的影响后,友伴网络结构与中学生的吸烟行为仍然有非常明显的关系。     

友伴关系与中学生的吸烟行为

友伴关系与中学生吸烟行为有非常直接的关系,然而,对此进行的研究却很少.社会网络结构分析技术的提出使研究者可以同时从友伴相互接纳和友伴地位两个角度对这一问题展开研究.从北京市1所普通中学和1所重点中学选取1091名初一至高三的学生为被试,运用NEGOPY软件包对中学生的友伴关系进行分析,结果发现,友伴相互接纳和友伴地位与中学生的吸烟行为都有显著的关系,为今后对中学生的吸烟行为进行预防和干预提供了非常重要的依据.     

聋校低年级学生班级友伴网络建构及其特点研究— 一项两年的追踪研究

本文采用调查法与社会网络分析法对聋校三年级聋生在班级群体中的友伴网络进行2年的追踪研究,以探索友伴网络的建构及其动态发展特征。结果表明：①三年级初期,聋生在友伴网络的个体中心度与个体的外貌、成绩与年龄等个人特征有显著相关;但随年级升高,这种相关性逐渐消失。②聋生友伴网络中存在一个十分稳定的中心小团体,其团体成员在整个网络中处于中心地位。③聋生在班级群体中的互选朋友关系呈现出中等程度的稳定性。     

西方友伴研究的新视角

友伴关系及友伴互动是儿童社会性发展研究的重要主题，在西方倍受重视。近年来，该领域岛研究们大胆创新，开辟了一些新视角，开始注意从性别角色、情感、发展性和跨化等角度去对友伴进行研究。本拟就这些新视角及其相关成果作一概述，供作进一步研究的参考。

Similarity in depressive symptoms in adolescents' friendship dyads: selection or socialization?

This study examined friendship selection and socialization as mechanisms explaining similarity in depressive symptoms in adolescent same-gender best friend dyads. The sample consisted of 1,752 adolescents (51% male) ages 12-16 years (M = 13.77, SD = 0.73) forming 487 friend dyads and 389 nonfriend dyads (the nonfriend dyads served as a comparison group). To test our hypothesis, we applied a multigroup actor-partner interdependence model to 3 friendship types that started and ended at different time points during the 2 waves of data collection. Results showed that adolescents reported levels of depressive symptoms at follow-up that were similar to those of their best friends. Socialization processes explained the increase in similarity exclusively in female dyads, whereas no evidence for friendship selection emerged for either male or female dyads. Additional analyses revealed that similarity between friends was particularly evident in the actual best friend dyads (i.e., true best friends), in which evidence for socialization processes emerged for both female and male friend dyads. Findings highlight the importance of examining friendship relations as a potential context for the development of depressive symptoms.     

Stable same‐sex friendships with higher achieving partners promote mathematical reasoning in lower achieving primary school children

This study was designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same‐sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and 1 year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal actor‐partner interdependence model) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning.     

The Relationship Between Friendship Quality and Self-Esteem in Adolescent Girls and Boys

Much has been written about the low self-esteem of adolescent girls relative to adolescent boys, but little research has explored the role that friendship quality may play in affecting self-esteem. Ninety-seven female and 67 male 11th and 12th graders completed measures of self-esteem and of friendship quality with both same- and cross-gender best friends. Ninety-five percent of the participants were White, and ranged across the socioeconomic spectrum with the majority coming from middle-class families. We found that girls' self-esteem was significantly lower than boys' self-esteem and that girls rated their relationships as stronger, more interpersonally rewarding, and more stressful than boys did. Boys reported that their friendship with their best female friend was more interpersonally rewarding than their friendship with their best male friend, whereas girls rated the quality of their same- and cross-gender friends similarly. As expected, girls' self-esteem was positively correlated with the friendship quality of their cross-gender best friend. However, their self-esteem was not correlated with the quality of their same-gender friendship. Boys' self-esteem did not correlate with the quality of their same- or cross-gender best friendship. Results may help us understand the relatively low self-esteem experienced by adolescent girls.     

Friendship Similarity During Early Adolescence: Gender and Racial Patterns

We studied the relationship of reciprocity, gender, and racial composition (Caucasian, African American, cross-race) of adolescent friendship dyads to similarity and proximity in 136 young adolescents. We found that adolescents selected friends who were of the same gender and race and that female dyads were more similar than male dyads on verbal achievement and several personality dimensions. Caucasian dyads were more similar than African American dyads on verbal achievement, mental alertness, and dominance. African American adolescents had more contact with their best friends outside school, whereas Caucasian adolescent friends had more in-school contact. African American students had fewer reciprocal relationships than the Caucasian students. Cross-race friendships were less reciprocal than same-race friendships. Race and gender were important in determining friendship patterns. Similarity and proximity were more important than reciprocity in understanding early adolescent friendships.

A Multimethod Exploration of the Friendships of Children Considered Socially Withdrawn by Their School Peers

Friendships of children considered socially withdrawn by their school peers were investigated within a population of elementary school children. Reciprocal friends were identified by a friendship nomination procedure; social withdrawal was assessed by peer nominations. Trained graduate students rated videotapes of dyads of friends (n = 58 dyads, of which 29 contained at least one withdrawn child) for selected features of friendship quality. In addition, each friend within a dyad provided ratings of the quality of the relationship. The videotaped data showed the withdrawn children to be somewhat restricted in their verbal communication with their friends, and less competitive with their friends, than were friends in a comparison group. In dyads consisting of one withdrawn and one nonwithdrawn child, the withdrawn child perceived the relationship as characterized by greater closeness and helpfulness than did the nonwithdrawn friend. Despite some signs of inhibited behavior within the friendship context, withdrawn children seem to have access to close friendships of high quality.     

Daily School Context of Adolescents' Single Best Friendship and Adjustment

Research on adolescent best friendships typically focuses on school-based friendships, ignoring important differences between classroom-based and out-of-school friendships. With data from 156 ninth-grade students, many of whom named more than 1 best friend across the 14-day period, the authors examined associations between the daily school context of one's best friendship and adjustment. Benefits of in-grade best friendships were found in academic engagement when a composite was assessed across the 2-week period. Daily findings were more complex and were different between weekends and school days. Out-of-grade best friends were named more frequently on weekends, and on weekend days in which they named an out-of-school best friend participants spent more time with that friend but felt like less of a good student. Implications for our understanding of friendship context and for the measurement of friendship itself are discussed.     

Adolescents' use of affiliative and aggressive strategies during conflict with romantic partners and best-friends

Objective: Developmental theory suggests romantic relationships present unique demands when adolescents transition from the interaction patterns of same-sex friendships to cross-gender interactions. A possible response is to incorporate behaviours of the other gender: girls adopting aggressive strategies and boys adopting affiliative ones. The goal of this study is to explore this hypothesis by comparing conflict resolution among romantic couples and same-sex best friends. Method: Observational methods were employed with 37 female best friends, 22 male best friends and 37 romantic couples. Of the romantic couples, 35 also were observed with a best friend. Affiliative and aggressive behaviours were tabulated during two conflict tasks. Results: Female best friends were more affiliative than male best friends and romantic partners; these latter dyads were more aggressive than the female best friends. Within group comparisons indicated that boys and girls decreased their affiliative behaviours, especially verbal humour, and increased their aggressive behaviours, especially teasing, when observed with the romantic partner compared to the best friend. Decomposing the romantic dyad, girlfriends displayed relatively more aggressive behaviours than their boyfriends, and boyfriends exhibited more affiliative behaviours. Conclusions: Findings shed light on gendered shifts in patterns of interaction as adolescents transition from same-sex friendships to romantic relationships.
