Smoking cessation in college fraternities and sororities

描述(申请人提供)：烟草使用造成的癌症死亡占所有癌症死亡的30%。尽管美国成年人吸烟的总体流行率正在下降，但大学生的吸烟率却有所上升，最近的估计表明，吸烟率可能高达33%。本研究的主要目的是评估以吸烟(TX)为重点的激励性访谈咨询干预与以水果和蔬菜为重点的注意力控制条件(C)对希腊大学(兄弟会和女生联谊会)成员戒烟的效果。由于每天吸烟的大学生很少，报告吸烟范围广泛的学生(即在过去30天中吸烟1至30天)将通过他们的希腊组织被招募参加健康干预。将鼓励学生参与，无论他们是否有退出的兴趣。这项研究将采用双臂随机分组设计。在两个月的时间里，TX和C臂的学生将接受4次使用激励性面试咨询的个人课程。在这项研究中，德克萨斯州和哥伦比亚大学的学生都将收到专门为大学生设计的戒烟提示单。将在兄弟会和联谊会一级进行随机化，以最大限度地减少潜在的污染，并最大限度地招募和留住参与者。我们预计，将需要24个希腊小组，每个小组有20名符合条件的吸烟者来检测拟议的治疗效果。为了增加包容性，我们还将招收来自历史上黑人希腊字母组织的学生，这些组织将形成两个额外的集群，每个集群约有10名吸烟者，总共26个集群，由500名大学吸烟者组成。主要的假设是，在随机化的6个月后，接受以吸烟(TX)为重点的动机访谈的吸烟者在30天的时点戒烟率(定义为在过去30天内不吸烟)将显著高于接受注意力控制条件(C)的吸烟者。我们还将测试干预对短期(7天)和长期(90天)戒烟、减少吸烟以及变化阶段的影响。在干预结束时，我们将进行按吸烟状况分层的焦点小组，以确定影响干预成功或失败的因素。最终，我们设想，如果干预有效，可以作为预先打包的干预措施，通过希腊社区、居民住房和学生健康/咨询中心进行传播。

DESCRIPTION (provided by applicant): Tobacco use is responsible for 30% of all cancer deaths. Although the overall prevalence of adult cigarette smoking is declining in the US, the rate among college students has increased, and recent estimates suggest the prevalence may be as high as 33%. The primary aim of this study is to assess the efficacy of a motivational interviewing counseling intervention focused on smoking (Tx) versus an attention control condition focused on fruits and vegetables (C) for smoking cessation among members of college Greek (fraternity and sorority) organizations. Since few college students who smoke do so every day, students reporting a wide range of tobacco smoking (i.e., out of the past 30 days, smoking cigarettes from 1 to 30 days) will be recruited through their Greek organizations to participate in a health intervention. Students will be encouraged to participate regardless of their interest in quitting. This study will use a group-randomized design with two arms. Over two months, students in the Tx and C arms will receive 4 individual sessions using motivational interviewing counseling. Students in both Tx and C will receive quit tip sheets developed specifically for college students in this study. Randomization will occur at the level of fraternity and sorority to minimize potential contamination and to maximize recruitment and retention of participants. We project that 24 Greek groups with 20 eligible smokers in each will be required to detect the proposed treatment effect. To increase inclusiveness we will also enroll students from historically black Greek letter organizations, who will form two extra clusters each with about 10 smokers for a total of 26 clusters comprised of 500 college smokers. The primary hypothesis is that, at 6 months from randomization, smokers receiving motivational interviewing focused on smoking (Tx) will have significantly higher 30-day point prevalence abstinence (defined as no cigarettes in the past 30 days) than smokers receiving a attention controlled condition (C). We will also test the effect of the intervention on short term (7-day) and long-term (90-day) abstinence, on cigarette reduction, and on movement along the stages of change. At the conclusion of the intervention, we will conduct focus groups stratified by smoking status to identify factors that contributed to the intervention success or failure. Ultimately, we envision that the intervention, if efficacious, could be used as a pre-packaged intervention disseminated through the Greek community, residential housing, and student health/counseling centers.
