Research on the effect of suicide stories in the media on suicide in the real world has been marked by much debate and inconsistent findings. Recent narrative reviews have suggested that research based on nonfictional models is more apt to uncover imitative effects than research based on fictional models. There is, however, substantial variation in media effects within the research restricted to nonfictional accounts of suicide. The present analysis provides some explanations of the variation in findings in the work on nonfictional media. Logistic regression techniques applied to 419 findings from 55 studies determined that: (1) studies measuring the presence of either an entertainment or political celebrity were 5.27 times more likely to find a copycat effect, (2) studies focusing on stories that stressed negative definitions of suicide were 99% less likely to report a copycat effect, (3) research based on television stories (which receive less coverage than print stories) were 79% less likely to find a copycat effect, and (4) studies focusing on female suicide were 4.89 times more likely to report a copycat effect than other studies. The full logistic regression model correctly classified 77.3% of the findings from the 55 studies. Methodological differences among studies are associated with discrepancies in their results.
关于媒体中自杀报道对现实世界中自杀行为的影响的研究一直存在诸多争议且结果不一。近期的叙述性综述表明,基于非虚构模式的研究比基于虚构模式的研究更有可能发现模仿效应。然而,在仅限于自杀非虚构报道的研究中,媒体效应存在很大差异。本分析对非虚构媒体研究结果的差异提供了一些解释。应用逻辑回归技术对55项研究的419个结果进行分析后发现:(1)测量娱乐或政治名人出现情况的研究发现模仿效应的可能性高出5.27倍;(2)关注强调自杀负面定义的报道的研究报告模仿效应的可能性低99%;(3)基于电视报道(其报道量少于平面媒体报道)的研究发现模仿效应的可能性低79%;(4)关注女性自杀的研究报告模仿效应的可能性比其他研究高出4.89倍。完整的逻辑回归模型正确分类了55项研究中77.3%的结果。研究之间的方法差异与其结果差异相关。
