这篇文章说明了潜在转换分析（LTA）的使用，这是一种用于测试个体成长阶段序列模型的方法。LTA是潜在类理论的产物，是一种特殊类型的潜在马尔可夫模型，强调使用多个显式指标。LTA用于比较早期青少年物质使用开始的2个模型的拟合度，并评估以学校为基础的物质使用预防计划对7年级和8年级学生的影响。出现了几个有趣的发现。首先，包括酒精和烟草使用作为可能的起点的物质使用开始模型比包括酒精使用作为唯一起点的模型拟合得更好。第二，在七年级时尝试过吸烟但没有尝试过饮酒的学生似乎处于加速发作的轨迹上。第三，规范教育预防计划总体上是成功的，除了那些在七年级只尝试过烟草的学生。（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
This article illustrates the use of latent transition analysis (LTA), a methodology for testing stage-sequential models of individual growth. LTA is an outgrowth of latent class theory and is a particular type of latent Markov model emphasizing the use of multiple manifest indicators. LTA is used to compare the fit of 2 models of early adolescent substance use onset and to assess the effects of a school-based substance use prevention program on Ss measured in 7th grade and again in 8th grade. Several interesting findings emerged. First, a model of substance use onset including both alcohol and tobacco use as possible starting points fit better than a model that included alcohol use as the only starting point. Second, Ss who had tried tobacco but not alcohol in 7th grade seemed to be on an accelerated onset trajectory. Third, the normative education prevention program was generally successful, except for the students who had tried only tobacco in 7th grade.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
