概要 Background: Previous analyses of the Werther effect have focused on the role of traditional media outlets such as newspapers and television, failing to consider the similar influence that online media may bear. Aim: This study examined the link between Internet reports about incidents of suicide and searches employing suicide-related terms. Methods: We analyzed suicide reports on websites linked from Google News Japan within the period from July to October 2010, and examined their cross correlation with the volume of searches employing suicide-related search terms ("shinitai (I want to die)", "jisatsu houhou (suicide method)", and "ryuuka suiso (hydrogen sulfide)") available in the Google Insight for Search. Results: A significantly positive correlation between the number of reports on celebrity suicides and the volume of searches employing the term "shinitai" and "jisatsu houhou". The volume of searches employing the term "ryuuka suiso" exhibited a significantly positive correlation with that same day's total number of reports on completed suicides, reports on completed suicides involving non-celebrities, and reports describing the details of the people who died by suicide. Conclusion: The results were consistent with the idea that suicide reports, especially those involving celebrities, lead to an increase of searches employing suicide-related terms within a few days after the reports. A phenomenon similar to the Werther effect was observed between Internet suicide reports and Internet searches employing suicide-related terms.
