A study was conducted to determine what sociocultural and demographic variables can be used to identify potential problem drinkers among adolescents in middle school and high school. Three thousand seventeen students were administered an in-depth questionnaire regarding their knowledge, attitudes, and behavior toward the use of alcohol. Twenty schools in six school districts in the two-state area of Georgia and South Carolina participated in the study. A number of analyses indicated that the student heavy drinker was most typically male, white, and between the ages of 14 and 15 years with an above average knowledge about alcohol and liberal attitudes toward alcohol use. The adolescent heavy drinker is more likely to have parents and best friends who are heavy drinkers, to have had his first encounter with alcohol at an early age, to drink with friends his own age, and to feel that almost all of his friends drink. Results of this study can be used by family physicians in the management of potential alcohol abusers. Early recognition and intervention by the family physician may help to reduce the alarming number of adolescents who are struggling with problems related to alcohol.
