The Data Management, Measurement, and Statistics core (DMMS) will focus on four aims: (1) to provide state-of-the-art data management and statistical resources and support across projects; (2) to develop common, psychometrical-ty sound measures to use across projects, notably measures of smoking behaviors and outcomes; (3) to implement cross-project, integrated analyses; and (4) to develop statistical techniques and approaches to address key issues related to the analysis of adolescent smoking data. ( 1) SUPPORT. A computerized database will be maintained containing all longitudinal reseamh data obtained from EMA forms, structured interviews, adolescent and parent questionnaires, schools, and physiological measurements. Rigorous methods for data entry, editing, and updating will be implemented to ensure that the data are clean, consistent, and secure. Detailed documentation of the database will be developed by this core. Statistical support and collaboration for all projects will be provided. (2) MEASUREMENT. The program project aims to increase understanding of the longitudinal patterns of adolescent smoking and the emotional and social contexts in which these occur. A DMMS core aim is to conceptualize and develop measures that will: (a) characterize longitudinal smoking patterns and (b) be tractable and interpretable in the analysis of the contexts in which these patterns develop. (3) INTEGRATION. A key feature of the program project is that data will be available from the main study cohort (seven waves) and the three projects. In the DMMS, development of statistical models that allow integrated analyses of data from many sources will be a major priority. This v, ill be accomplished using a variety of advanced statistical approaches. The goal is to obtain a more complete picture of adolescent smoking than could be obtained from analyzing the data separately. (4) DEVELOPMENT. Methodological research within the DMMS core will seek to advance development of statistical approaches for the analysis of smoking data. These efforts will be focused around the following primary issues: the conceptualization/combination of multiple indices of"dependence," individual heterogeneity in smoking development across time, heterogeneity in the influence of smoking predictors, and characterizing stages of smoking dependence.

数据管理，测量和统计核心（DMM）将重点关注四个目标：（1）提供 跨项目的最新数据管理以及统计资源和支持； （2）发展 常见的，精神上的声音措施跨项目使用，尤其是吸烟行为的措施 和结果； （3）实施跨项目，集成分析； （4）开发统计技术 和解决与青少年吸烟数据分析有关的关键问题的方法。 （1）支持。将维护一个计算机数据库，其中包含所有纵向reseamh数据 从EMA表格，结构化访谈，青少年和家长问卷，学校以及 生理测量。严格的数据输入，编辑和更新的方法将实施 确保数据清洁，一致和安全。数据库的详细文档将是 由这个核心开发。将为所有项目提供统计支持和协作。 （2）测量。该计划项目旨在提高对纵向模式的理解 青少年吸烟以及发生的情感和社会背景。 DMMS的核心目的是 概念化和制定将：（a）表征纵向吸烟模式的措施，（b） 在对这些模式发展的上下文的分析中可解释的。 （3）集成。该计划项目的一个关键特征是从主要研究中获得数据 队列（七波）和三个项目。在DMM中，开发统计模型允许 来自许多来源的数据的集成分析将是重点。这个V，使用一个 各种高级统计方法。目标是获得青少年的更完整的图片 吸烟比分别分析数据可获得的吸烟。 （4）发展。 DMMS核心内的方法论研究将寻求提高发展 用于分析吸烟数据的统计方法。这些努力将集中在以下 主要问题：“依赖”多个指数的概念化/组合，个人 跨时间吸烟的异质性，吸烟预测因子影响的异质性， 并表征吸烟依赖的阶段。
