Abstract: Social network theory and analysis technique are applied to explore the relationship between peer network structure and cigarette smoking of middle school students. 1091 7th to 12th graders were selected from one ordinary middle school and one key middle school in Beijing city, asked to nominate up to 10 friends, and reported their own and their friends smoking behaviors on a 3-point scale. NEGOPY software was used to analyze peer network structure of middle school students, and each student was identified as clique member, liaison or isolate. The result shows that clique members were more significant than liaisons and isolates, but decreased with grade. There were significant differences on cigarette smoking among the clique member, liaison and isolate. The cigarette use of clique member was lowest, and the cigarette use of isolate was highest. Logistic regression analysis found the effects of peer network structure on cigarette smoking of middle school students was still significant, even if the effects of gender, grade, and school type were excluded.

Key words: middle school students, cigarette smoking, peer network

摘要： 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。
