Student alcohol use is viewed as a major problem by college officials. To examine the frequency and consequences of college student alcohol use, 927 undergraduates completed a questionnaire which included demographic variables and items assessing the frequency and negative consequences of their drinking and the drinking behavior of their parents and friends. Analysis of results showed that 92% of the respondents reported drinking alcohol, and 47% reported intoxication at least once a week. About the same percentage of men and women reported drinking, but men reported more frequent intoxication and more negative consequences. Higher grades were associated with lower levels of drinking. No differences in students' drinking patterns were found as a result of parent alcohol problems, year in school, or place or residence, but students whose parents had drinking problems reported more negative consequences from their own drinking. About half the respondents were aware of alcohol-related problems in friends. Counseling, self-help groups, and campus-wide alcohol education programs should consider these differences in order to reach all groups having alcohol problems. (JAC)
