The Role of Protective Behavioral Strategies, Social Environment, and Housing Type on Heavy Drinking among College Students.

<italic>Background</italic>: Though research has examined heavy drinking by housing type, the link between type of college student housing and protective behavioral strategies (PBS) has rarely been examined comparing different college campuses. <italic>Objectives</italic>: The purpose of this study is to examine the role of housing type, perceptions of peer drinking, and PBS with respondent heavy drinking among undergraduate college students from one Southeastern and one Midwestern university in the United States. <italic>Methods</italic>: 1,448 college students enrolled in undergraduate courses at two public universities completed a paper and pencil survey of attitudes and experiences about dating, sexuality, and substance use. Data were analyzed using multiple group path analysis. <italic>Results</italic>: Students living in Greek housing perceived their close friends as engaging in more risky drinking, and had higher rates of heavy drinking compared to those living in other housing types. The effect of perceptions of peer drinking on PBS was significantly different between campuses as were several other indirect pathways to heavy drinking. <italic>Conclusion/Importance</italic>: Understanding more about the differing roles of college residential environments can help inform effective drinking interventions, and reduce heavy drinking among college students.
