Core--Measurement

本TTURC中描述的研究项目集中在吸烟行为与相关的遗传遗传力、心理表型和社会文化环境因素之间的关系。除了评估美国的吸烟行为外，这三个项目都将在中国进行评估。测量核心将提供一个结构，以整合、支持和补充这些活动，并促进 TTURC项目的研究人员。TTURC中包括的主要评估是对烟草和酒精的表型、心理倾向和环境风险因素的评估。测量核心将参与与中心调查人员的迭代过程，以完善和确定与其研究相关的适当措施。一般来说，测量核心将(1)进行文献搜索，以确定现有的测量方法，监督研究 在研究项目的第一年没有适当的措施时，与TTURC项目协商制定、试行测试和验证新的措施，并在接下来的几年研究中就每个项目的措施提供必要的咨询。(3)与统计核心合作评估测量的信度和效度，(4)在统计核心的帮助下评估测量的跨文化等价性，(5)根据项目需要制作问卷、调查工具和评估表，(6)向基于网络的测量库添加经过验证的量表，(7)评估中国数据收集程序的质量，(8)就测量问题对学生和工作人员进行培训。统计核心将协助测量核心进行研究设计、数据管理和统计分析。

The research projects described in this TTURC focus on the relationships between smoking behaviors and associated genetic heritability, psychological phenotypes, and socio-cultural environmental factors. In addition to assessing smoking behaviors in the United States, all three Projects will make assessments in China. The Measurement Core will provide a structure to integrate, support, and supplement these activities and to facilitate collaboration among researchers in TTURC projects. Major assessments included in the TTURC are assessments of tobacco and alcohol phenotypes, psychological dispositions, and environmental risk factors. The Measurement Core will participate in an iterative process with the center investigators to refine and identify appropriate measures relevant to their studies. In general, the Measurement Core will (1) conduct literature search to identify existing measures, monitor the research literature to stay current with new published measures, and consult with TTURC Projects on developing, pilot testing and validating new measures when no appropriate measure exists at the first year of the Research Projects, and provide necessary consultation on measures for each individual Project in the following years of research. (2) translate measures into Chinese (3) assess reliability and validity of measures in collaboration with the Statistics Core, (4) evaluate the cross-cultural equivalence of measures with assistance from the Statistics Core, (5) produce quetionnaires, survey instruments, and evaluation forms as needed by the projects, (6) add validated scales to the web-based measures bank, (7) evaluate quality of data collection procedures in China, (8) train students and staff on measurement issues. The Statistics Core will assist the Measurement Core on study design, data management, and statistical analysis.
