PROJECT SUMMARY (See instructions): In this renewal, the Data Management, Measurement, and Stafistics (DMMS) Core will confinue to focus on four primary aims: (1) to provide expert data entry, management, and stafistical support across projects; (2) to develop common, psychometricahly sound measures (notably measures of smoking behaviors and outcomes) to use across projects; (3) to implement cross project, integrated analyses; and (4) to propose and develop stafisfical approaches to address key issues related to the analysis of adolescent smoking data. (1) SUPPORT. As in the original project, we will develop and maintain a computerized database for data entry and management, and we will develop detailed documentation ofthe database. We will continue to ufilize rigorous methods for data entry, edifing, and updafing to ensure that the data are clean, consistent, and secure. We will also provide stafistical support and collaboration for all projects. (2) MEASURES. We will assess smoking at mulfiple fimes and with mulfiple measures. A specific aim of the DMMS Core is to conceptualize and develop measures that will (a) aid in the identificafion of longitudinal smoking patterns and (b) aid in the interpretafion of contexts in which these patterns develop. (3) INTEGRATION. A key feature of the program project is that data will be available from the full cohort through questionnaires administered in Project 1 (four annual assessments) in addifion to data collected from subsets of the cohort in each of the other three projects. A major priority within the DMMS Core is to develop stafisfical models that allow integrated analyses of data from many sources. (4) DEVELOPMENT. Methodological research within the DMMS core will seek to advance the development of statisfical approaches for the analysis of smoking data. These efforts will be focused around three primary issues: the conceptualization/combinafion of mulfiple indices of "dependence," individual heterogeneity in smoking development across fime, and characterizing influences of heterogeneity.

项目摘要（请参阅说明）： 在此续约中，数据管理，测量和Stafistics（DMMS）核心将重点关注四个主要目标：（1）在项目中提供专家数据输入，管理和确定支持； （2）开发常见的心理测量措施（尤其是吸烟行为和结果的措施），以在项目中使用； （3）实施跨项目，集成分析； （4）提出和开发适应性方法，以解决与青少年吸烟数据分析有关的关键问题。 （1）支持。与原始项目一样，我们将开发和维护一个用于数据输入和管理的计算机数据库，我们将开发数据库的详细文档。我们将继续为数据输入，调整和更新的严格方法延长，以确保数据清洁，一致和安全。我们还将为所有项目提供出色的支持和协作。 （2）措施。我们将通过毛ulfiple量和Mulfiple措施评估吸烟。 DMMS核心的一个具体目的是概念化和制定措施，以（a）辅助纵向吸烟模式的识别，以及（b）帮助对这些模式发展的上下文的解释。 （3）集成。该计划项目的一个关键功能是，将通过项目1（四个年度评估）中管理的问卷从整个队列中获得数据，以使其从其他三个项目中的同类集群中收集的数据中添加数据。 DMMS核心中的主要优先级是开发适应性模型，以允许对许多来源的数据进行集成分析。 （4）发展。 DMMS核心内的方法论研究将寻求推动开发吸烟数据分析的指定方法。这些努力将集中在三个主要问题上：“依赖性”的概念化/组合，跨冰期吸烟开发中的个体异质性，以及表征异质性的影响。
