A number of recent reports have documented a positive association between mass media news stories about suicide and subsequent short-term increases in total U.S. suicides. However, the estimated magnitude of this association varies considerably across these published reports and tends to be smaller in the more comprehensive studies. A detailed investigation of all network television suicide news stories broadcast between January 1, 1973, and December 31, 1984, was undertaken to resolve this inconsistency. The information about television coverage of suicides was more comprehensive than in previous studies. The analyses show that there was no reliable association between news stories and suicides among adults at any time over the 12 years investigated. A reliable association existed among teenagers between 1973 and 1980. This association reversed in 1981, however, and the relative risk of suicide associated with network news stories was consistently less than 1.0 through the end of the study period.
最近的一些报告记录了大众媒体关于自杀的新闻报道与美国自杀总数随后的短期增加之间的正相关关系。然而，在这些已发表的报告中，这种关联的估计幅度差异很大，并且在更全面的研究中往往较小。为了解决这种不一致性，对1973年1月1日至1984年12月31日期间播出的所有网络电视自杀新闻报道进行了详细调查。有关电视自杀报道的信息比以前的研究更全面。分析表明，在所调查的12年中的任何时候，新闻报道与成年人自杀之间都没有可靠的关联。1973年至1980年期间，青少年之间存在可靠的关联。然而，这种关联在1981年发生了逆转，并且在研究期结束时，与网络新闻报道相关的自杀相对风险一直小于1.0。
