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.
越来越多的证据表明，模仿行为可能在青少年自杀中起作用。我们研究了1984 - 1985年秋冬在电视上播出四部虚构电影的前后两周内，纽约大区青少年自杀和自杀未遂的数量变化。播出后两周内的未遂平均数（22例）显著高于播出前的平均数（14例；P小于0.05），并且在三部电影播出后，与预测数量相比，自杀既遂显著增加（P小于0.05）。我们得出结论，这些结果与以下假设一致，即一些青少年自杀是模仿行为，而且对于这些发现的其他解释，如转介到医院的数量增加或法医或医院工作人员对青少年自杀行为的敏感性增加，不太可能解释自杀未遂和既遂的增加。
