目前的研究试图确定青少年饮酒的成长轨迹类别，并检查与类别相关的预测因素和结果。以学校为基础的样本评估了7到12年级的酒精使用情况。采用潜伏期生长混合模型。结果显示有5种不同的纵向饮酒模式。最常见的两种饮酒模式包括7至12年级偶尔非常少量的饮酒，以及酒精使用量和频率的适度增加。其中一组人在整个研究期间不经常饮酒，但饮酒量很高。另一组在数量和频率上都出现了快速升级。最后一组在七年级开始于高频率和高数量水平，并表现出频率的快速下降。情绪困扰和冒险是这些课程的突出之处，所有课程，特别是快速自动扶梯，都显示出与酒精相关的问题水平高于偶尔饮酒非常少的人。
The current study sought to identify classes of growth trajectories of adolescent alcohol use and to examine the predictors and outcomes associated with the classes. Alcohol use was assessed from Grades 7 to 12 in a school-based sample. Latent growth mixture modeling was used. and results indicated 5 discrete longitudinal drinking patterns. The 2 most common drinking patterns included occasional very light drinking from Grades 7 to 12 and moderate escalation in both quantity and frequency of alcohol use. One group drank infrequently but at high levels throughout the study period. Another group exhibited rapid escalation in both quantity and frequency. The final group started at high levels of frequency and quantity in Grade 7 and showed rapid de-escalation in frequency. Emotional distress and risk taking distinguished the classes, and all classes, particularly rapid escalators, showed elevated levels of alcohol-related problems relative to occasional very light drinkers.
