Core--Measurement

本TTURC中描述的研究项目涉及评估与烟草有关的社会心理变量，例如与吸烟有关的文化价值观、接触支持反烟草的媒体以及感知到的社会规范。不幸的是，这些构造的验证度量通常是不可用的。测量核心将通过研究、开发和验证与烟草有关的社会心理变量的测量来协助其他项目。测量核心将执行以下职能：-进行文献综述，以确定与烟草有关的社会心理变量的现有测量方法。-制定与烟草有关的社会心理变量的新措施，如接触支持和反对烟草的媒体、对吸烟的社会规范以及与吸烟有关的文化价值观。-帮助调查人员调整现有的措施，用于早期青少年和/或阅读能力有限的受访者。-评估不同文化和语言之间衡量标准的可比性。-在目标人口的青少年样本中对现有和新的措施进行试点试验。-对这些测量进行信度和效度研究，包括内部一致性信度、重测信度、构念效度、内容效度、并发效度、预测效度、区别效度。-监测研究文献，及时了解最新公布的与烟草有关的社会心理变量测量方法。-为学生和受训者提供学习测量问题的机会。-维护出版标准，现有数据集和文档库。-识别和调查我们正在进行的研究中出现的其他测量问题。-在使用定性和人种学研究方法方面为调查人员提供咨询和指导。

The research projects described in this TTURC involve the assessment of tobacco-related psychosocial variables, such as cultural values relevant to smoking, exposure to pro- ant anti-tobacco media, and perceived social norms. Unfortunately, validated measures of these constructs often are not available. The Measurement Core will assist the other projects by researching, developing, and validating measures of tobacco-related psychosocial variables. The Measurement Core will perform the following functions: - Conduct literature reviews to identify existing measures of tobacco- related psychosocial variables. - Develop new measures of tobacco-related psychosocial variables, such as exposure to pro- and anti-tobacco media, perceived social norms about smoking, and cultural values relevant to smoking. - Help the investigators adapt existing measures for use with early adolescents and/or respondents with limited reading proficiency. - Assess the comparability of measures across cultures and languages. - Pilot test the existing and new measures in samples of adolescents from the target populations. - Conduct reliability and validity studies of these measures, including internal consistency reliability, test-retest reliability, construct validity, content validity, concurrent validity, predictive validity, and discriminant validity. - Monitor the research literature to stay current with new published measures of tobacco-related psychosocial variables. - Provide access to students and trainees to learn about measurement issues. - Maintain a library of publishes measures, existing datasets, and documentation. - Identify and investigate other measurement issues as they arise in our ongoing research. - Provide consultation and guidance to investigators in the use of qualitative and ethnographic research methods.
