The Statistical Support and Data Management (SS&DM) Core will promote the theme of the Center for Advancing Longitudinal Drug Abuse Research by facilitating the use of advanced statistical methods for analysis of longitudinal data and the cost-effective acquisition and management of longitudinal data. Specific aims are: 1) provide statistical consultation to Center researchers on analysis issues specifically relevant to longitudinal research on drug abuse and its interaction with drug treatment and other service systems; 2) develop and deliver a program of statistical education on analysis of longitudinal data, specialized to drug abuse research applications; 3) conduct analysis of data combined and/or compared across multiple studies in order to develop, expand, compare, and validate complex models; 4) provide consultation on strategies for the efficient acquisition and processing of high quality data; and 5) promote the accessibility and comparability of data acquired by Center projects. Core activities will include consultation to Center-supported and collaborating researchers on statistical and data-related issues; development of procedures, examples and applications to support consultation; workshops for statisticians, researchers, and consumers of research results; and cross-project analyses. Analytic methods will include generalized linear/non-linear models and structural equation modeling with latent variables for growth curves, multi-level, and multiple group models. Core staff will work with Center and collaborating researchers to identify and refine research questions and hypotheses related to drug use trajectories and their interaction with service systems such as drug treatment, criminal justice, and mental health. Efforts should lead to improved application of analytic methods, better data quality, more effective use of research results, and increased productivity.

统计支助和数据管理核心将促进推进药物滥用纵向研究中心的主题，促进使用先进的统计方法分析纵向数据，并以具有成本效益的方式获取和管理纵向数据。具体目标是：1）就药物滥用纵向研究及其与药物治疗和其他服务系统的相互作用的具体相关分析问题向中心研究人员提供统计咨询; 2）开发和提供纵向数据分析的统计教育计划，专门用于药物滥用研究应用; 3）对多项研究中合并和/或比较的数据进行分析 为了开发、扩展、比较和验证复杂的模型; 4）提供关于高质量数据的有效获取和处理的策略的咨询; 5）促进中心项目所获取数据的可访问性和可比性。核心活动将包括：就统计和数据相关问题向中心支助和协作的研究人员提供咨询;开发支持咨询的程序、实例和应用程序;为统计人员、研究人员和研究成果消费者举办讲习班;跨项目分析。分析方法将包括广义线性/非线性 模型和结构方程模型与潜在变量的增长曲线，多层次，多组模型。核心工作人员将与中心和合作研究人员合作，以确定和完善与药物使用轨迹及其与药物治疗，刑事司法和心理健康等服务系统的相互作用相关的研究问题和假设。应通过努力改进分析方法的应用，提高数据质量，更有效地利用研究成果，并提高生产率。
