寻求有关自杀的信息和新闻的人可能会使用互联网。然而，不同国家与自杀相关的搜索量和国家自杀率之间的关系的证据可能会截然不同。我们的目标是调查意大利人口(2008-2012年)自杀率与谷歌自杀相关搜索量之间的关系，使用意大利死亡率数据库，该数据库提供了关于自杀的月度数据(2008-2012年)。此外，这项研究的目的是根据我们获得的2013-14年期间的结果，确定全国自杀率的未来趋势。谷歌趋势提供了在线月度搜索量的数据--在谷歌搜索和谷歌新闻(2008-2014)中使用了“自杀”、“自杀”和“如何自杀”三个词。谷歌搜索“自杀”一词的搜索量比“自杀”落后三个月(p=0.482，p-Value<；0.001)，而“自杀”和“如何自杀”的搜索量与全国自杀率之间没有相关性。谷歌新闻对这三个词的搜索量结果是白噪音。显然，在意大利，在线搜索与自杀相关的词汇更有可能与自杀以外的因素联系在一起，比如个人兴趣和自杀性丧亲。
People seeking information and news regarding suicide are likely to use the Internet. However, evidence of the relationship between suicide-related search volumes and national suicide-rates in different countries can be strikingly different. We aimed to investigate the relationship between suicide-rates and Google suicide-related search volumes in the Italian population (2008-2012) using the Italian mortality database that provided monthly national data concerning suicides (2008-2012). Moreover, this study aimed to identify future trends of national suicide rates on the basis of the results we obtained concerning the period 2013-14. Google Trends provided data of online monthly search-volumes of the term "suicide", "commit suicide" and "how to commit suicide" in Google Search and Google News (2008-2014). Google Search volumes for the term "suicide" lags suicide by three months (p=0.482, p-value < 0.001), whereas no correlation was found between search volumes for "commit suicide" and "how to commit suicide" and national suicide rates. Google News search volumes for the three terms resulted in white noise. Apparently, online searches for suicide-related terms in Italy are more likely to be linked to factors other than suicidiality such as personal interest and suicide bereavement.
