Smokers' Quitline for Asian Language Speakers

描述(申请人提供)：这项研究的动机是吸烟造成的严重公共健康问题，以及为少数族裔背景的吸烟者提供的循证戒烟服务的缺乏。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效果：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，这造成了在理解他们的行为和开发帮助他们戒烟的方法方面的知识差距。目前还没有关于更喜欢使用亚洲语言的吸烟者电话咨询的疗效数据，尽管电话干预对这些群体来说是有希望的，因为它很方便，而且有可能接触到大量吸烟者。 具体目的是：(1)测试一种对文化敏感的咨询协议的有效性，该协议针对吸烟者拨打加州吸烟者帮助热线的中文、韩语和越南语线路；(2)检查干预效果是否受到文化适应的影响；(3)检查干预效果是否因认知和行为预测戒烟成功的因素而有所不同；(4)检查家庭参与是否在戒烟成功中发挥作用；以及(5)评估三个种族之间的咨询效果差异。 在这个双臂设计中，受试者按语言(汉语、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)将提供有关人口统计学、吸烟行为、戒烟史和其他心理社会变量的基线信息。在服用后4个月、7个月和13个月进行的独立评估将确定受试者是否尝试戒烟，以及他们在保持戒酒方面的成功程度。这一丰富的数据集也将被用来分析文化适应、家庭参与以及基线行为和认知变量是否会影响干预效果。 这项拟议的研究在几个方面具有重要意义。首先，它将及时为传统上服务不足的人群(说亚洲语言的人)提供戒烟方法的信息。其次，如果被证明是成功的，电话咨询可以广泛应用，因为近年来集中服务的戒烟电话激增。第三，这项研究以说亚洲语言的人为对象，解决了种族差异的问题，这一问题已被许多人(包括NCI Bypass Budget)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.
