Abstract

Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and growth mixture models, are highly relevant to developmental science because they can identify subgroups of people who are similar in their patterns of change. This guide highlights foundational aspects of these two types of models and is intended for readers who have not previously conducted either an LPTA or a GMM, or perhaps no mixture model analyses at all. It includes four primary sections. The first focuses on understanding mixture models conceptually and applying that knowledge to identifying appropriate research questions. The second section addresses data requirements, including planning for data collection or evaluating the suitability of previously collected data, and data preparation. The third section focuses on conducting analyses, with step-by-step instructions and syntax, and the final section discusses presenting the results. I illustrate these concepts and procedures with an example data set and research questions derived from the Five Cs model of positive youth development.

潜在轮廓转换分析和生长混合模型:儿童和青少年发展研究人员的非常非技术指南。
发展科学家通常对在发展方面具有共性的人的子群体感兴趣;这些子组通常不能直接捕获,而必须从其他信息中推断出来。混合模型可用于这些情况。两种特定类型的混合模型,潜在轮廓过渡分析和生长混合模型,与发展科学高度相关,因为它们可以识别出在变化模式上相似的人群。本指南强调了这两种模型的基本方面,并且是为以前没有进行过LPTA或GMM,或者可能根本没有混合模型分析的读者准备的。它包括四个主要部分。第一部分侧重于从概念上理解混合模型,并应用这些知识来确定适当的研究问题。第二部分涉及数据需求,包括数据收集计划或评估先前收集数据的适用性,以及数据准备。第三部分侧重于执行分析,包括逐步说明和语法,最后一部分讨论如何呈现结果。我用一个例子数据集和研究问题来说明这些概念和程序,这些问题来自于积极青年发展的五个c模型。

期刊介绍: The mission of New Directions for Child and Adolescent Development is to provide scientific and scholarly presentations on cutting edge issues and concepts in the field of child and adolescent development. Each issue focuses on a specific new direction or research topic, and is peer reviewed by experts on that topic. Any topic in the domain of child and adolescent development can be the focus of an issue. Topics can include social, cognitive, educational, emotional, biological, neuroscience, health, demographic, economical, and socio-cultural issues that bear on children and youth, as well as issues in research methodology and other domains. Topics that bridge across areas are encouraged, as well as those that are international in focus or deal with under-represented groups. The readership for the journal is primarily students, researchers, scholars, and social servants from fields such as psychology, sociology, education, social work, anthropology, neuroscience, and health. We welcome scholars with diverse methodological and epistemological orientations.
