DESCRIPTION (provided by applicant): Research is currently underway that seeks to deepen our understanding of the role of genetic factors in substance dependence and response to treatment. In order for the potential benefits of emerging research to be realized, it is crucial to begin understanding how members of different racial/ethnic groups comprehend, interpret and respond to information about the role of genetics in addiction and treatment response, and in particular to reported racial differences in the frequency of alleles hypothesized to increase susceptibility to addiction or affect response to treatment. We use data on the genetics of nicotine addiction and response to treatment to explore these issues. Specific aims are: (1) To explore racial differences (self-identified Black versus white) in beliefs and understandings regarding the role of genetics in addiction; (2) To explore racial differences (self-identified Black vs. white) in attitudes toward the use of genetic testing to improve treatment for addiction; (3) To assess the extent to which individuals' attitudes toward the use of genetic testing in this context change when they are informed of key characteristics of the genotypes that would most likely be used to tailor individual treatment for addiction (e.g., racial differences in the frequency of risk alleles, pleiotropic associations), as reported in the most current scientific literature; (4) Among a subset of self-identified Black and white smokers in the U.S., to assess individuals' intention/willingness to undergo genetic testing in order to be matched to optimal smoking treatment. This study includes extensive qualitative research and a randomized national telephone interview survey of 1200 self-identified Black and 1200 white adults. Focus groups, personal interviews, cognitive interviews, expert review, two rounds of pre-testing, and a pilot survey (N=100) will be used to develop an effective and appropriate survey instrument. The proposed research will be the first to examine how diverse lay audiences understand, interpret and respond to emerging genetic research on addiction and potential clinical applications. Such information is essential to constructively engage the broader public in ongoing and future debates about the integration of emerging pharmacogenetic interventions into clinical practice, and to developing culturally appropriate informed consent processes, interventions and educational activities.

描述（由申请人提供）：研究目前正在进行中，旨在加深我们对遗传因素在物质依赖和治疗反应中的作用的理解。为了实现新兴研究的潜在益处，开始了解不同种族/民族群体的成员如何理解，解释和回应有关遗传学在成瘾和治疗反应中的作用的信息是至关重要的，特别是报告的等位基因频率的种族差异，假设增加成瘾的易感性或影响对治疗的反应。我们使用尼古丁成瘾的遗传学数据和对治疗的反应来探索这些问题。具体目标是：（1）探讨种族差异（自我认同的黑人与白色）在关于遗传在成瘾中的作用的信念和理解方面;（2）探索种族差异（自我认同的黑人与白色）对使用基因检测改善成瘾治疗的态度;（三）为了评估当个体被告知最可能影响基因检测的基因型的关键特征时，他们对在这种情况下使用基因检测的态度发生变化的程度。可能用于定制成瘾的个体治疗（例如，风险等位基因频率的种族差异，多效性关联），如最新的科学文献中所报道的;（4）在美国自我认定的黑人和白色吸烟者的子集中，评估个人接受基因测试的意向/意愿，以便与最佳吸烟治疗相匹配。这项研究包括广泛的定性研究和随机全国电话采访调查的1200自我认定的黑色和1200白色成人。焦点小组，个人访谈，认知访谈，专家评审，两轮预测试和试点调查（N=100）将被用来开发一个有效的和适当的调查工具。这项拟议中的研究将是第一个研究不同的外行观众如何理解，解释和回应新兴的成瘾遗传研究和潜在的临床应用。这些信息对于建设性地让更广泛的公众参与正在进行的和未来的关于将新兴药物遗传学干预措施纳入临床实践的辩论，以及制定文化上适当的知情同意程序，干预措施和教育活动至关重要。
