CORE--BIOBEHAVIORAL METHODS CORE

生物行为方法核心的目的是提高研究的质量，重点是降低以下弱势群体的风险：老年人、儿童、少数族裔和社会经济资源很少的人。具体地说，这个核心是为了满足CRRVP的第二个目标：加强中心调查人员/附属机构使用的方法，并培训新手测量生物行为变量、数据管理和数据分析。该核心的目标是：(A)就生物措施的使用提供咨询和支助；(B)提供咨询和 为衡量行为和经验措施提供支助；(C)提供咨询和服务，以支持数据收集、管理、分析和共享；(D)提供方案，促进调查人员和项目工作人员在方法学问题上的发展。这一核心是作为现有的P20中心的一部分建立的。新扩大的服务包括：(A)通过双能X射线吸收测量法测试人体性能和测量身体成分的数据收集服务；(B)支持定性研究；(C)面试官培训；(D)计算机编程，以便利在外地收集数据。生物行为方法核心由五个组件组成，前两个组件 (B)生物标记物；(C)行为和经验方法；(D)数据管理、分析和共享；以及(E)调查员发展。

The purpose of the Biobehavioral Methods Core is to enhance the quality of research that focuses on reducing risks in the following vulnerable populations: older adults, children, raciaVethnic minorities, and people with few socioeconomic resources. Specifically, this core was designed to meet the second aim of the CRRVP: strengthen the methodologies used by Center investigators/affiliates and train novices regarding the measurement of biobehavioral variables, management of data, and analysis of data. The aims of the core are to: (a) provide consultation and support for the use of biological measures; (b) provide consultation and support for the measurement of behavioral and experiential measures; (c) provide consultation and services to support data collection, management, analysis, and sharing; and (d) provide programs for development of investigators and project staff with respect to methodological issues. This core was established as part of the existing P20 Center. New expanded services include (a) data collection services for tests of human performance and measures of body composition by dual-energy x-ray absorptiometry; (b) support for qualitative research; (c) interviewer training; and (d) computer progranmling to facilitate data collection in the field setting. The Biobehavioral Methods Core is organized into five components, the first two of which are biological: (a) human performance/body composition; (b) biological markers; (c) behavioral and experiential methods; (d) data management, analysis, and sharing; and (e) investigator development.
