Smoking cessation in college fraternities and sororities

描述（由申请人提供）：烟草使用占所有癌症死亡的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在上升，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为重点的动机性访谈咨询干预（Tx）与以水果和蔬菜为重点的注意控制条件(C)对大学联谊会（兄弟会和姐妹会）组织成员戒烟的效果。由于每天吸烟的大学生很少，因此报告吸烟范围广泛的学生（即，在过去30天内，吸烟1至30天）将通过其希腊组织招募参加健康干预。无论学生是否有兴趣退出，都将鼓励他们参加。本研究将采用两组随机设计。在两个多月的时间里，Tx和C组的学生将接受4次单独的动机访谈咨询。在这项研究中，德克萨斯州和C州的学生都将收到专门为大学生开发的戒烟提示单。随机化将在兄弟会和姐妹会的水平上进行，以尽量减少潜在的污染，并最大限度地招募和保留参与者。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，我们还将招收历史上来自黑人希腊字母组织的学生，他们将组成两个额外的小组，每个小组约有10名吸烟者，总共26个小组，由500名大学生吸烟者组成。主要假设是，在随机化后的6个月，吸烟者接受以吸烟为重点的动机性访谈（Tx）将比接受注意力控制条件(C)的吸烟者具有显著更高的30天点患病率戒烟（定义为在过去30天内没有吸烟）。我们还将测试干预对短期（7天）和长期（90天）戒烟的影响，对减少吸烟的影响，以及对改变阶段的运动的影响。在干预结束时，我们将根据吸烟状况进行分组，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，可以作为预先包装的干预措施在希腊社区、住宅和学生健康/咨询中心传播。

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.
