Self-reported campus alcohol policy and college alcohol consumption: a multilevel analysis of 4592 Korean students from 82 colleges

Abstract

Background: Campus alcohol policy has been associated with student alcohol consumption in numerous studies. However, more information is required to assess the extent to which school policy affects student drinking behavior; especially when both individual-level sociodemographic characteristics of students and area-level characteristics of college campuses are controlled for. Thus, this paper explores the association between campus alcohol policy and student alcohol consumption among a nationally representative sample of college students in South Korea, while controlling for both individual and area-level characteristics. Methods: We surveyed and analyzed the data of 4592 students from 82 colleges. Multilevel (hierarchical) linear modeling was used to identify the association between campus alcohol policy and alcohol consumption levels, measured via the AUDIT-C (Alcohol Use Disorders Identification Test-Consumption). Controlled individual-level characteristics included sex, year level, major, GPA (grade point average), pocket money, smoking status, stress level, depressive thoughts, suicidal thoughts, and number of clubs/organizations. Controlled area-level characteristics included college type, number of students, number of faculty members, number of workers/administrators, and region. Results: Compared to students unaware of their school's campus alcohol policy, students who self-reported that their campuses allow drinking in outdoor spaces (β = 0.755 p = 0.010) or in all areas (β = 0.820, p = 0.044) had higher AUDIT-C scores. Students attending schools with a large number of students, males, freshmen, students with low GPA, students with high amounts of pocket money, and smokers also had higher alcohol consumption scores relative to their peers. Alcohol education experience in the form of lectures, mail, and/or campaigns were not associated with student alcohol consumption levels. Conclusion: Our results suggest an association between self-reported campus alcohol policy and student alcohol consumption. College educators and administrators must be aware that relative to students unaware of their school's campus alcohol policy, students at colleges that allow drinking in outdoor spaces or all areas consume higher amounts of alcohol than their peers; even when area-level factors are controlled for.

Associations between Gender, Alcohol Use and Negative Consequences among Korean College Students: A National Study

“…The survey design was approved-the Institutional Review Board of Yonsei University College of Medicine granted approval for this survey instrument (Approval Number: Y−2017–0084). See the first publication from this study for more details about the methodology [ 6 ].…”

“…The only other published research targeting Korean college students highlighted how stress, depression and suicide risk were correlated with excessive alcohol consumption [ 3 , 4 , 5 ]. A recent article examined whether school policies and education programs play a role in discouraging student drinking behavior in Korea [ 6 ].…”

Individual and Contextual Characteristics Associated With Alcohol Use Among Brazilian Adolescents

“…The school is an important space for the development of policies aimed at reducing the consumption of alcohol and other substances such as illicit drugs and cigarettes [ 13 , 14 ]. Policies in well-established educational institutions have positive results in student behaviors, such as reducing alcohol consumption, improving academic performance and decreasing problematic attitudes [ 15 , 16 ].…”

A Social Ecological Approach to Hazardous Alcohol Use among Flemish Higher Education Students

“…One of the shortcomings of most studies, however, is that they focus on only one or two levels of influence. Usually, this includes individual-level characteristics, as well as characteristics of the higher education environment (e.g., social involvement, social norms, campus policy) [ 1 , 24 , 25 , 26 ].…”
