Core--Measurement

本TTURC中描述的研究项目涉及评估与烟草相关的心理社会变量，如与吸烟相关的文化价值观、接触支持反烟草的媒体以及感知的社会规范。不幸的是，这些结构的有效措施往往不可用。测量核心将通过研究、开发和验证与烟草相关的心理社会变量的测量来协助其他项目。测量核心将履行以下职能：-进行文献综述，以确定与烟草相关的心理社会变量的现有测量方法。- 制定与烟草有关的心理社会变量的新措施，如接触支持和反对烟草的媒体，对吸烟的社会规范的看法，以及与吸烟有关的文化价值观。- 帮助研究者调整现有的测量方法，以用于早期青少年和/或阅读能力有限的受访者。- 评估各种文化和语言之间衡量标准的可比性。- 在目标人口中的青少年样本中对现有措施和新措施进行试点测试。- 进行信度和效度研究，包括内部一致性信度，重测信度，结构效度，内容效度，同时效度，预测效度和区分效度。- 监测研究文献，以保持与烟草相关的心理社会变量的最新出版的措施。- 为学生和学员提供了解测量问题的机会。- 维护发布度量、现有数据集和文档的库。- 识别和调查其他测量问题，因为它们出现在我们正在进行的研究。- 在使用定性和人种学研究方法方面为研究者提供咨询和指导。

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.
