Longitudinal latent growth models were used to examine the relation between changes in adolescent alcohol use and changes in peer alcohol use over a 3-year period in a community-based sample of 363 Hispanic and Caucasian adolescents. Both adolescent alcohol use and peer alcohol use were characterized by positive linear growth over time. Not only were changes in adolescent alcohol use closely related to changes in peer alcohol use, but the initial status on peer alcohol use was predictive of later increases in adolescent alcohol use and the initial status on adolescent alcohol use was predictive of later increases in peer alcohol use. These results are inconsistent with models positing solely unidirectional effects between adolescent alcohol use and peer alcohol use.
纵向潜在增长模型被用于研究363名西班牙裔和白种青少年的社区样本在3年期间青少年饮酒变化与同伴饮酒变化之间的关系。青少年饮酒和同伴饮酒均呈现出随时间的正向线性增长特征。青少年饮酒的变化不仅与同伴饮酒的变化密切相关，而且同伴饮酒的初始状态可预测青少年后期饮酒量的增加，青少年饮酒的初始状态也可预测同伴后期饮酒量的增加。这些结果与仅假设青少年饮酒和同伴饮酒之间存在单向影响的模型不一致。
