Abstract:  Television viewing and aggressive behavior were assessed over a 17-year interval in a community sample of 707 families with a child (51% male) between the ages of 1 and 10 randomly sampled from two counties in northern New York State for whom data were available through 1991-3 regarding TV viewing and through 2000 regarding aggressive behavior. The parent and youth versions of the Diagnostic Interview Schedule for Children (DISC-I) were administered to assess offspring psychiatric disorders and aggressive or criminal behavior in 1983 and 1985-86. An age-appropriate modification of the DISC-1 was administered to the offspring in 1991-93. Mothers and youths were both interviewed in 1983 and 1985-86. There was a significant association between the amount of time spent watching television during adolescence and early adulthood and the likelihood of subsequent aggressive acts against others. This association remained significant after previous aggressive behavior, childhood neglect, family income, neighborhood violence, parental education, and psychiatric disorders were controlled statistically.
