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，以及少数民族背景的吸烟者缺乏基于证据的戒烟服务。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、韩国和越南。亚裔美国人是吸烟研究中被研究最少的群体之一，这在了解他们的行为和制定帮助他们戒烟的方法方面造成了知识差距。尽管电话干预因其便利性和接触到大量吸烟者的潜力而对这些群体有希望，但对喜欢使用亚洲语言的吸烟者进行电话咨询的有效性数据尚未报道。

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.
