可供发展论者使用的一套统计方法正在不断扩大，使有关随时间变化的问题能够以新的、信息丰富的方式得到解决。事实上，随着时间的推移，模型变化方法的新发展为提出新的研究问题创造了可能性。潜在转移分析是潜在类别分析的纵向延伸，是一种可以用于对离散潜在变量（例如阶段过程）的发展进行建模的方法。目前的文章说明了这种方法使用一个新的SAS程序，PROC LTA，随着时间的推移，在青少年和年轻人的约会和性风险行为的模型变化。性别差异进行了检查，物质使用行为包括在约会和性风险行为和过渡的初始状态的预测随着时间的推移。
The set of statistical methods available to developmentalists is continually being expanded, allowing for questions about change over time to be addressed in new, informative ways. Indeed, new developments in methods to model change over time create the possibility for new research questions to be posed. Latent transition analysis, a longitudinal extension of latent class analysis, is a method that can be used to model development in discrete latent variables, for example, stage processes, over 2 or more times. The current article illustrates this approach using a new SAS procedure, PROC LTA, to model change over time in adolescent and young adult dating and sexual risk behavior. Gender differences are examined, and substance use behaviors are included as predictors of initial status in dating and sexual risk behavior and transitions over time.
