Abstract：
BACKGROUND: Chinese immigrants experience significant disparities in tobacco use. Culturally adapted tobacco treatments targeting this population are sparse and the use is low. The low use of these treatment programs is attributed to their exclusive focus on individuals who are ready to quit and the wide range of barriers that Chinese immigrants face to access these programs. To support Chinese immigrant smokers at all levels of readiness to quit and address their access barriers, we developed the WeChat Quit Coach, a culturally and linguistically appropriate WeChat (Tencent Holdings Limited)-based peer group mobile messaging smoking cessation intervention.
OBJECTIVE: This study aims to assess the feasibility, acceptability, and preliminary effects of WeChat Quit Coach.
METHODS: We enrolled a total of 60 Chinese immigrant smokers in 2022 in New York City for a pilot randomized controlled trial (RCT) and a single-arm pilot test. The first 40 participants were randomized to either the intervention arm (WeChat Quit Coach) or the control arm (self-help print material) using 1:1 block randomization stratified by sex. WeChat Quit Coach lasted 6 weeks, featuring small peer groups moderated by a coach, daily text messages with text questions, and chat-based instant messaging support from the coach in response to peer questions. The next 20 participants were enrolled in the single-arm pilot test to further assess intervention feasibility and acceptability. All 60 participants were offered a 4-week supply of complimentary nicotine replacement therapy. Surveys were administered at baseline and 6 weeks, with participants in the pilot RCT completing an additional survey at 6 months and biochemical verification of abstinence at both follow-ups.
RESULTS: Of 74 individuals screened, 68 (92%) were eligible and 60 (88%) were enrolled. The majority of participants, with a mean age of 42.5 (SD 13.8) years, were male (49/60, 82%) and not ready to quit, with 70% (42/60) in the precontemplation or contemplation stage at the time of enrollment. The pilot RCT had follow-up rates of 98% (39/40) at 6 weeks and 93% (37/40) at 6 months, while the single-arm test achieved 100% follow-up at 6 weeks. On average, participants responded to daily text questions for 25.1 days over the 42-day intervention period and 23% (9/40) used the chat-based instant messaging support. Most participants were satisfied with WeChat Quit Coach (36/39, 92%) and would recommend it to others (32/39, 82%). At 6 months, self-reported 7-day point prevalence abstinence rates were 25% (5/20) in the intervention arm and 15% (3/20) in the control arm, with biochemically verified abstinence rates of 25% (5/20) and 5% (1/20), respectively.
CONCLUSIONS: WeChat Quit Coach was feasible and well-received by Chinese immigrants who smoke and produced promising effects on abstinence. Large trials are warranted to assess its efficacy in promoting abstinence in this underserved population.

摘要：
背景：中国移民在烟草使用方面存在显著差异。针对该群体的文化适应的烟草处理是稀疏的,并且使用是低的。这些治疗计划的使用率较低，这归因于它们专门针对准备退出的个人，以及中国移民在获得这些计划时面临的各种障碍。支持中国移民吸烟者在各个层面做好戒烟准备，并解决他们的准入障碍，我们开发了微信退出教练，一种文化和语言上适当的微信（腾讯控股有限公司）为基础的同行组移动消息戒烟干预。
目的：本研究旨在评估可行性，可接受性,微信退出教练的初步效果。
方法：我们于2022年在纽约市共招募了60名中国移民吸烟者，进行了一项先导随机对照试验（RCT）和单臂先导试验。前40名参与者被随机分配到干预组（微信退出教练）或对照组（自助打印材料），使用按性别分层的1：1分组随机分组。微信退出教练持续了6周,由教练主持的小型同伴团体，每日短信与文本问题，以及教练在回答同伴问题时基于聊天的即时消息支持。接下来的20名参与者参加了单臂试点测试，以进一步评估干预的可行性和可接受性。所有60名参与者都接受了为期4周的免费尼古丁替代疗法。在基线和6周进行调查，试验RCT的参与者在6个月时完成一项额外的调查，并在两次随访中对禁欲进行生化验证。
结果：在接受筛查的74个人中，68人（92%）符合资格，60人（88%）入组。大多数参与者,平均年龄为42.5（SD13.8）岁，是男性（49/60，82%），还没有准备好戒烟，70%(42/60)在登记时处于考虑前或考虑阶段。试验RCT在6周时的随访率为98％（39/40），在6个月时为93％（37/40），而单臂测试在6周时实现了100%的随访。平均而言,参与者在42天的干预期内回答了25.1天的每日文本问题,23%(9/40)的参与者使用了基于聊天的即时消息支持.大多数参与者对微信退出教练感到满意（36/39，92％），并会向其他人推荐（32/39，82％）。6个月时,自我报告的7天点患病率在干预组中为25％（5/20），在控制组中为15％（3/20），生化验证的禁欲率为25%(5/20)和5%(1/20)，分别。
结论：微信戒烟教练是可行的，受到吸烟的中国移民的欢迎，并对禁欲产生了有希望的效果。有必要进行大型试验，以评估其在这一服务不足的人群中促进禁欲的功效。
