Smokers' Quitline for Asian Language Speakers

描述（由申请人提供）：本研究的动机是吸烟引起的严重公共卫生问题，以及缺乏针对少数民族背景吸烟者的循证戒烟服务。这项研究测试了电话咨询对来自三个亚洲语言群体的吸烟者的影响：中国人，韩国人和越南人。亚裔美国人是吸烟研究中研究最少的群体之一，这在理解他们的行为和开发帮助他们戒烟的方法方面造成了知识差距。没有关于偏好使用亚洲语言的吸烟者的电话咨询的有效性数据的报告，尽管电话干预对这些群体有希望，因为它的便利性和它可能接触到大量的吸烟者。 具体目标是：（1）测试一个对文化敏感的咨询方案对吸烟者的有效性，即拨打加州吸烟者帮助热线的中文、韩文和越南语线路，（2）检查干预效果是否受到文化适应的调节，（3）检查干预效果是否因戒烟成功的认知和行为预测因素而异，（4）检查家庭参与是否在戒烟成功中发挥作用，（5）评估三个族群的谘商效果差异。 在这个双臂设计中，受试者按语言（中文、韩语和越南语）和性别分层，并随机接受电话咨询或自助材料，作为对照。受试者（N= 2，100）将提供关于人口统计学、吸烟行为、戒烟史和其他心理社会变量的基线信息。服用后4、7和13个月的独立评估将确定受试者是否进行了戒烟尝试，以及他们在保持禁欲方面的成功程度。这个丰富的数据集也将被用来分析是否文化适应，家庭参与，以及基线行为和认知变量修改干预效果。 拟议的研究在几个方面具有重要意义。第一，它将及时提供关于传统上得不到充分服务的人群（讲亚洲语言的人）的戒烟方法的信息。第二，如果被证明是成功的，电话咨询可以被广泛应用，因为近年来集中服务的戒烟热线激增。第三，通过针对亚洲语言的人，这项研究解决了种族差异的问题，这已被许多人（包括NCI旁路预算）确定为研究重点。

DESCRIPTION (provided by applicant): This study is motivated by the serious public health problems caused by smoking and by the paucity of evidence-based cessation service for smokers of ethnic minority backgrounds. The study tests the effects of telephone counseling for smokers from three Asian language-speaking groups: Chinese, Korean, and Vietnamese. Asian Americans are among the least studied groups in smoking research, which has created a knowledge gap in understanding their behavior and in developing methods to help them quit. No efficacy data have been reported for telephone counseling of smokers who prefer to use Asian languages, although telephone intervention holds promise for these groups because of its convenience and its potential to reach large number of smokers. The specific aims are to: (1) test the efficacy of a culturally sensitive counseling protocol for smokers calling the California Smokers' Helpline on its Chinese, Korean, and Vietnamese lines, (2) examine whether intervention effects are moderated by acculturation, (3) examine whether intervention effects vary by cognitive and behavioral predictors of cessation success, (4) examine whether family involvement plays a role in quitting success, and (5) assess differences in counseling effect across the three ethnic groups. In this two-arm design subjects are stratified by language (Chinese, Korean, and Vietnamese) and gender and randomized to telephone counseling or self-help materials, which serves as the control. Subjects (N=2,100) will provide baseline information on demographics, smoking behavior, quitting history, and other psychosocial variables. Independent evaluations at 4, 7, and 13 months after intake will determine whether subjects made a quit attempt and how successful they were at remaining abstinent. This rich data set will also be used to analyze whether acculturation, family involvement, and baseline behavioral and cognitive variables modify the intervention effect. The proposed study is significant in several ways. First, it will provide timely information on a cessation approach for a traditionally under-served population (Asian language speakers). Second, if proven successful, telephone counseling can be widely applied because of the proliferation of quitlines with centralized services in recent years. Third, by targeting Asian language speakers this study addresses the issue of ethnic disparities, which has been identified by many (including the NCI Bypass Budget) as a research priority.
