This study examined relationships among parental monitoring, family conflict, and subgroups of adolescent alcohol use identified through longitudinal latent class analyses (LLCA). Differences in these subgroups across sex and race/ethnicity were also examined. The present study used data (N = 4,067; 51% male, 49% female) collected during a longitudinal study in which adolescents completed questionnaires each semester for seven semesters, beginning in spring of their freshman year of high school until spring of their senior year. LLCA demonstrated three classes of drinking over time (low, increasing, and moderate use). The majority of adolescents were increasing-use drinkers. Moderate drinkers were more likely to be male than female; nondrinkers were most likely to be African American; and increasing-use drinkers were more likely to be Mexican American. Adolescents who received less maternal monitoring and experienced more family conflict were more likely to be identified in the class of moderate alcohol use compared to nonuse. These results highlight the importance of encouraging parental monitoring and decreasing family conflict to reduce the likelihood of adolescent alcohol use throughout the high school years (PsycInfo Database Record (c) 2022 APA, all rights reserved).

父母监护、家庭冲突和青少年饮酒：纵向潜在类别分析。

本研究检查了通过纵向潜在类别分析 (LLCA) 确定的父母监控、家庭冲突和青少年酒精使用亚组之间的关系。还检查了这些亚组在性别和种族/民族方面的差异。本研究使用了纵向研究中收集的数据（N = 4,067；51% 男性，49% 女性），其中青少年每学期完成七个学期的问卷调查，从高中一年级的春季开始，直到他们大四的春季. 随着时间的推移，LLCA 展示了三类饮酒（低、增加和中度使用）。大多数青少年是越来越多的饮酒者。适度饮酒者男性多于女性；不饮酒者最有可能是非裔美国人；越来越多的饮酒者更有可能是墨西哥裔美国人。与未使用酒精相比，接受较少母亲监测和经历更多家庭冲突的青少年更有可能被确定为中度饮酒类别。这些结果强调了鼓励父母监督和减少家庭冲突以减少整个高中期间青少年饮酒的可能性的重要性（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
