Few studies have investigated the effect of college-level contextual factors on students' binge drinking. Most previous studies focused on the effect of individuals' characteristics on their binge drinking.
This study tested the effect of college-level contextual factors on students' binge drinking.
The 2006 National College Health Assessment data collected from 76,542 students in 113 U.S. 4-year colleges were analyzed using the Hox five-step hierarchical random effects logistic regression models.
College-level variables, such as percentages of male students, marijuana users, Black students, and students with Greek affiliation, significantly predicted students' binge drinking above and beyond student-level predictors. An intraclass correlation was 0.10 in the null model, indicating that 10% of students' binge drinking could be explained by differences among colleges. Significant cross-level interactions were found between college-level variables and student-level variables.
In order to reduce binge drinking in college, the findings underscore the need for active intervention within the college climate that addresses drinking.
很少有研究调查大学层面的背景因素对学生豪饮的影响。大多数先前的研究都集中在个体特征对其豪饮的影响上。
本研究测试了大学层面的背景因素对学生豪饮的影响。
采用 Hox 五步分层随机效应逻辑回归模型，对来自美国 113 所四年制大学的 76542 名学生的 2006 年全国大学生健康评估数据进行分析。
除学生层面的预测因素外，大学层面的变量，如男学生、大麻使用者、黑人学生和有希腊隶属关系的学生的比例，显著预测了学生的豪饮行为。在零模型中，组内相关系数为 0.10，表明 10%的学生豪饮行为可以用大学之间的差异来解释。还发现了大学层面变量和学生层面变量之间的显著跨层次交互作用。
为了减少大学生豪饮，研究结果强调需要在关注饮酒的大学氛围中采取积极干预措施。
