A prospective study of young men at high risk for alcoholism: school behavior and achievement.

From a large consecutive birth cohort in Denmark, 134 sons of alcoholic fathers (high-risk group) and 70 matched controls were selected for a prospective longitudinal study of alcoholism. A premorbid multidisciplinary assessment was conducted at age 19-20. Data were derived from three sources: a social worker interview, a psychopathological interview that also collected information about current drinking pattern, and a questionnaire sent to teachers. The high-risk group reported having experienced a more disturbed school career, and were rated by their teachers as having been more impulsive and as having had poorer verbal proficiency. These factors may be predictive of future alcoholism.
