青少年最亲密同性友伴的相似性

选取１０４０名北京市小六、初二和高一学生，探讨青少年与最亲密同性友伴的相似性，及性别组合、年级组合和单双向选择对最亲密同性友伴相似性的影响。要求被试提名一个与自己同校的最亲密友伴，并完成一份包括１７个方面的问卷。最后得到４２７对最亲密同性友伴。最亲密同性友伴的相似性超过非友伴。最亲密同性友伴在逃学或离家出走、吸烟饮酒等行为方面最相似，在参与活动方面的相似性次之，家庭社会经济地位、遵从友伴、学习与教育期望的相似性最低。性别组合、年级组合对最亲密同性友伴某些方面的相似性有明显影响，而单双向选择对最亲密同性友伴的相似性无明显影响。

SIMILARITY BETWEEN ADOLESCENTS AND THEIR SAME-GENDER BEST FRIENDS

Similarity between adolescents and their same-gender best friends were examined using data collected from 1040 6th, 8th, and 10th grade youth from several public schools in Beijing. Subjects were asked to nominate one best friend, and complete a questionnaire including 17 attributes. 427 same-gender best friend dyads were identified. The same-gender best friends were more similar than non-selected friends. They were more similar on behaviors such as skipping school, running away from home, smoking and drinking than on other activities, and the least similar on family socioeconomic status, dispositional compliance, school achievement and education aspiration. The effects of gender and grade of best friend dyads were significant on some attributes, the effects of reciprocity of same-gender best friend dyads were not significant on all attributes.
