背景：大麻的使用在青少年和年轻人中越来越普遍；然而，很少有研究在这个重要的发展时期检查大麻使用的纵向轨迹。因此，我们研究了青少年吸食大麻的轨迹和社会心理因素，这些因素可能会区分那些在青春期和青年期吸食大麻的人与那些没有吸食大麻的人。方法：参与者是1204名9年级和10年级的学生，他们在基线时过度抽样吸烟，并被跟踪超过6年，作为一项广泛的纵向研究的一部分，青少年吸烟模式的社会和情感背景（SECASP）研究。使用生长混合模型（GMM）对大麻使用轨迹进行建模，并使用混合效应回归分析来检查大麻使用随时间增加的社会心理相关因素。结果：我们的研究结果揭示了三个非升级用户轨迹（低用户、中等用户和高用户）和一个升级用户轨迹。我们发现，相对于不乘坐自动扶梯的人，乘坐自动扶梯的人吸烟的比例更高。（p < .0001），寻求新奇（p = .02），攻击和反社会行为（p < .007），以及与同伴环境相关的问题行为（p = .04）。此外，在其中一些关系中，还有重要的时间和按时间分组的互动。另一方面，父母控制和抑郁在自动扶梯和低、中等非扶梯使用者之间没有差异。结论：吸烟、追求新奇、攻击性和反社会行为以及同伴影响与青春期和青年期大麻使用的“升级”有关。(C) 2015 Elsevier Ltd.版权所有。
Background: Marijuana use is increasingly widespread among adolescents and young adults; however, few studies have examined longitudinal trajectories of marijuana use during this important developmental period. As such, we examined adolescent trajectories of marijuana use and the psychosocial factors that may differentiate individuals who escalate their marijuana use over adolescence and young adulthood from those who do not.Methods: Participants were 1204 9th and 10th graders at baseline who were over-sampled for cigarette use and were followed over 6-years, as part of an extensive longitudinal study, the Social and Emotional Contexts of Adolescent Smoking Patterns (SECASP) study. Growth Mixture Modeling (GMM) was used to model trajectories of marijuana use and Mixed Effects Regression analyses were used to examine psychosocial correlates of marijuana use escalation over time.Results: Our results revealed three trajectories of non-escalating users (low users, medium users, and high users) and one escalating user trajectory. We found that relative to Non-escalators the Escalators had higher cigarette smoking.(p < .0001), novelty-seeking (p = .02), aggressive and anti-social behavior (p < .007), and problem behavior related to peer context (p = .04). Moreover, there were important time and Group by Time interactions in some of these relationships. On the other hand, parental control and depression did not differ between escalators and low and medium non-escalating users.Conclusions: Cigarette smoking, novelty-seeking, aggressive and anti-social behavior, and peer influence are related to 'escalating' marijuana use throughout adolescence and young adulthood.
