African American smokers experience disproportionately higher rates of tobacco-related illnesses compared to Caucasians. It has been suggested that interventions targeted to specific racial/ethnic groups (i.e., culturally specific) are needed; however, the literature examining the efficacy of culturally specific interventions is equivocal. Moreover, there are few descriptions of methods used to create these interventions. The main aim of this study is to test the efficacy of a culturally specific smoking cessation intervention among African Americans.
METHODS/DESIGN: A 2-arm randomized controlled trial (RCT) will be conducted to assess the efficacy of a culturally specific group cognitive behavioral therapy (CBT), compared to standard group CBT among treatment-seeking smokers from the community. Participants in both conditions receive the transdermal nicotine patch (TNP) for 8-weeks. We intend to randomize at least 247 adult smokers who self-identify as African American into the trial. Enrolled participants are block randomized into one of two groups: Standard group CBT (control) or a culturally specific group CBT (CS-CBT). Groups are matched for time and attention, and consist of eight sessions. The primary outcome variable is 7-day point prevalence abstinence (7-day ppa). Smoking status is assessed at the end-of-counseling (EOC), and 3, 6, and 12-month follow-ups, with self-reported abstinence verified by saliva cotinine. We hypothesize that the CS-CBT condition will produce significantly greater smoking cessation rates compared to the control condition. We also expect that this effect will be moderated by acculturation and ethnic identity, such that the CS-CBT will show the greatest effect on cessation among participants who are less acculturated and have greater ethnic identity.
Answering the fundamental question of whether culturally specific interventions lead to incremental efficacy over established, evidence-based approaches is of utmost importance. This study will have implications for the development and implementation of smoking cessation interventions among African Americans and other racial/ethnic minority groups.

与白种人相比，非裔美国烟民患与烟草相关疾病的比例高得不成比例。有人认为需要针对特定种族/族裔群体（即具有文化针对性）的干预措施；然而，关于文化针对性干预措施的疗效的文献却存在争议。此外，关于这些干预措施的方法描述也很少。本研究的主要目的是检验一种针对非裔美国人的文化针对性戒烟干预措施的疗效。
方法/设计：将进行一项 2 臂随机对照试验（RCT），以评估一种文化针对性的团体认知行为疗法（CBT）与社区中寻求治疗的吸烟者的标准团体 CBT 相比的疗效。两种情况下的参与者都接受为期 8 周的透皮尼古丁贴片（TNP）治疗。我们计划随机分配至少 247 名自认为是非裔美国人的成年吸烟者参加该试验。入组的参与者按块随机分为两组：标准团体 CBT（对照组）或文化针对性团体 CBT（CS-CBT）。两组在时间和注意力上相匹配，共包括 8 个疗程。主要结局变量为 7 天点流行率戒断（7 天 ppa）。在咨询结束时（EOC）以及 3、6 和 12 个月的随访时评估吸烟状况，通过唾液可替宁自我报告的戒断情况进行验证。我们假设 CS-CBT 条件会产生显著更高的戒烟率，与对照组相比。我们还预计，这种效果将受到文化适应和种族认同的调节，即 CS-CBT 将在文化适应程度较低和种族认同度较高的参与者中对戒烟产生最大的效果。
回答文化针对性干预措施是否比既定的、基于证据的方法更有效这一基本问题至关重要。这项研究将对非裔美国人和其他种族/少数族裔群体的戒烟干预措施的制定和实施产生影响。
