Drawing upon ideas stemming from social disorganisation theory, this study explores how structural and social aspects of the school context affect youth substance-use behaviours in terms of smoking, alcohol and/or drug use. A key focus is to investigate the joint effect of school collective efficacy and schools’ substance-use norms on students’ substance use. Analyses are based on combined information from two independent data collections conducted in 2014 among ninth grade students (n = 5122) and teachers (n = 1105) in 81 senior-level schools in Stockholm. Results from multilevel analyses confirm previous research by suggesting that the proneness to engage in substance use varies depending on the socioeconomic profile of the school. Youth in socioeconomically advantaged schools were more prone to engage in substance use than youth in disadvantaged school settings. Furthermore, collective incentives for exerting social control against substance use seem to be weaker in schools where conventional values towards substance use (anti-substance-use norms) are suppressed.

学校层面的（不利）优势和青少年的物质使用行为：集体效能和规范的作用

本研究借鉴了社会解体理论的思想，探讨了学校环境的结构和社会方面如何影响青少年在吸烟、酗酒和/或吸毒方面的物质使用行为。一个重点是调查学校集体效能和学校物质使用规范对学生物质使用的联合影响。分析基于 2014 年在斯德哥尔摩 81 所高级学校的九年级学生 (n = 5122) 和教师 (n = 1105) 中进行的两次独立数据收集的综合信息。多层次分析的结果证实了之前的研究，表明吸毒倾向因学校的社会经济状况而异。社会经济优势学校的青年比贫困学校的青年更容易吸毒。此外，在对物质使用的传统价值观（反物质使用规范）被压制的学校中，对物质使用实施社会控制的集体激励似乎较弱。
