目的：烟草、酒精、大麻和其他药物的使用在高中期间增加，但人们对随着时间的推移的个人模式知之甚少，特别是同时使用多种物质的模式。本研究探讨了同时期物质使用的轨迹，以及个人和社会因素如何差异预测物质使用模式。方法：物质使用的纵向轨迹进行了检查，在全国代表性样本的学生（N = 2,512）在3年的时间内（10日至12年级）使用潜在的类分析。在10年级的个人，父母和同龄人的风险因素进行了检查，在轨迹类的成员。测试结果：确定了五类模型：非使用者（45.5%）;烟草，酒精和其他药物使用者（9.2%）;酒精和其他药物使用者（9.2%）;增加多种物质使用者（16.7%）;和减少多种物质使用者（19.4%）。基线时的抑郁症状与所有类别中成员资格的可能性较高相关，但增加的多种物质使用者类别除外，但当调整社会影响因素时，这种关联变得无关紧要。父母的监督知识与较低的可能性，在所有类的成员，除了增加多种物质的用户类，而感知父母的不赞成与较低的可能性，在烟草，酒精和其他药物用户类的成员。同伴物质使用与每个物质使用类别的成员资格的可能性较高。结论：所确定的纵向轮廓突出了10至12年级期间同时使用多种物质的普遍性和动态模式。消极的同伴影响会增加风险，而积极的父母行为会降低风险。研究结果是一致的需要，以促进社会影响和保护因素对青少年物质使用。
Objective: Use of tobacco, alcohol, marijuana, and other drugs increases during the high school years, yet little is known about individual patterns over time, particularly patterns of contemporaneous multiple-substance use. This study examined trajectories of contemporaneous substance use and how individual and social factors differentially predict patterns of substance use. Method: Longitudinal trajectories of substance use were examined in a nationally representative sample of students (N = 2,512) over a 3-year period (10th through 12th grades) using latent class analysis. Individual, parental, and peer risk factors in 10th grade were examined in relation to membership in trajectory classes. Result: A five-class model was identified: nonusers (45.5%); tobacco, alcohol, and other drug users (9.2%); alcohol and other drug users (9.2%); increasing multiple-substance users (16.7%); and decreasing multiple-substance users (19.4%). Depressive symptoms at baseline were associated with a higher likelihood of membership in all classes except the increasing multiple-substance-user class, but the association becomes insignificant when social influence factors were adjusted. Parental-monitoring knowledge was associated with a lower likelihood of membership in all classes except increasing multiple-substance-user class, whereas perceived parental disapproval was associated with a lower likelihood of membership in the tobacco, alcohol, and other drug user class. Peer substance use was associated with a higher likelihood of membership in each of the substance use classes. Conclusions: The identified longitudinal profiles highlight the pervasiveness and dynamic patterns of contemporaneous multiple-substance use during 10th through 12th grades. Negative peer influence increased risk, whereas positive parenting behaviors decreased risk. The findings are consistent with the need to foster social influences and protective factors against adolescent substance use.
