The impact of current residence and high school drinking on alcohol problems among college students.

Objective: This study examines relationships between type of (current) residence, heavy episodic drinking in high school and alcohol-related problems among college students.
Method: The study participants were respondents in the 1993, 1997 and 1999 Harvard School of Public Health College Alcohol Study (CAS) surveys of students attending 119 4-year U.S. colleges. Based on responses from 6,525 (55.6% female) students in the 1993 CAS, an exploratory factor analysis of the alcohol problem items was specified in a confirmatory factor analysis framework based on a four-factor solution, and related to study variables. The 1993 data were cross-validated with the 1997 and 1999 surveys.
Results: When compared with students living in single-gender dormitories, students living off campus with parents reported lower alcohol-related problem consequences and a higher probability of drinking/driving. Students residing off campus without parents, compared with students in single-gender dorms, reported a higher probability of drinking/driving. Associations between off-campus residence and probabilities for drinking/driving were mediated by frequency of driving. Students living in coed dormitories, when compared with students in single-gender dorms, incurred more problem consequences related to drinking but reported significantly lower probabilities associated with designated driving and drinking/driving. Heavy episodic drinking in high school was related to higher probabilities of problems on all outcome measures.
Conclusions: The presence of direct and independent effects for both heavy drinking prior to college and high-risk environmental factors in collegiate drinking practices support targeted and diverse strategies for prevention activities.
