社会规范和大麻使用之间的关系的研究一般集中在个人的态度，离开更大的社会层面的态度未知的影响。本研究调查了出生队列或时间段定义的大麻使用的社会层面的不赞成。设计：结合1976年至2007年对美国中学生进行的全国代表性年度调查的分析，作为监测未来研究的一部分。设置在美国青少年完成的在校调查。参与者：共有986 003名青少年在8年级，10年级和12年级。主要预测因素包括每个出生队列和时间段中不赞成大麻的学生的百分比。多层次模型与个人聚集在观察和出生队列的时间段进行了建模，与过去一年的大麻使用的结果。结果-结果表明，一个显着的和强大的影响，出生队列不赞成大麻的使用在预测个人风险的大麻使用，控制后，个人层面的不赞成，感知规范大麻和其他特征。与大多数（87-90.9%）青少年不赞成使用大麻的出生队列相比，在不到一半（42-46.9%）不赞成的队列中使用大麻的几率高出3.53倍（99%置信区间：2.75，4.53）。结论出生队列中更不赞成使用大麻的个人不太可能使用大麻，独立于他们对大麻使用的个人态度。关于大麻使用的社会规范和态度在出生队列中聚集，即使在控制了个人对规范的态度和看法之后，这种聚集对大麻使用也有直接影响。
Aims Studies of the relationship between social norms and marijuana use have generally focused on individual attitudes, leaving the influence of larger societal-level attitudes unknown. The present study investigated societal-level disapproval of marijuana use defined by birth cohort or by time-period. Design Combined analysis of nationally representative annual surveys of secondary school students in the United States conducted from 1976 to 2007 as part of the Monitoring the Future study. Setting In-school surveys completed by adolescents in the United States. Participants A total of 986 003 adolescents in grades 8, 10 and 12. Measurements Main predictors included the percentage of students who disapproved of marijuana in each birth cohort and time-period. Multi-level models with individuals clustered in time-periods of observation and birth cohorts were modeled, with past-year marijuana use as the outcome. Findings Results indicated a significant and strong effect of birth cohort disapproval of marijuana use in predicting individual risk of marijuana use, after controlling for individual-level disapproval, perceived norms towards marijuana and other characteristics. Compared to birth cohorts in which most (87-90.9%) adolescents disapproved of marijuana use, odds of marijuana use were 3.53 times higher in cohorts where fewer than half (42-46.9%) disapproved (99% confidence interval: 2.75, 4.53). Conclusions Individuals in birth cohorts that are more disapproving of marijuana use are less likely to use, independent of their personal attitudes towards marijuana use. Social norms and attitudes regarding marijuana use cluster in birth cohorts, and this clustering has a direct effect on marijuana use even after controlling for individual attitudes and perceptions of norms.
