Increasing evidence suggest that imitative behavior may have a role in suicide among teenagers. We studied the variation in the numbers of suicides and attempted suicides by teenagers in the greater New York area two weeks before and two weeks after four fictional films were broadcast on television in the fall and winter of 1984-1985. The mean number of attempts in the two-week periods after the broadcasts (22) was significantly greater than the mean number of attempts before the broadcasts (14; P less than 0.05), and a significant excess in completed suicides, when compared with the number predicted, was found after three of the broadcasts (P less than 0.05). We conclude that the results are consistent with the hypothesis that some teenage suicides are imitative and that alternative explanations for the findings, such as increased referrals to hospitals or increased sensitivity to adolescent suicidal behavior on the part of medical examiners or hospital personnel, are unlikely to account for the increase in attempted and completed suicides.
