Depression is the most common disorder in people who attempt suicide or die by suicide. Research review indicate that therapy of depression (including psychoeducation) is one of the main factors in the prevention of suicidal behavior. In this paper we examine the intensification of search interest for the terms "depression" and "suicide" in Google search engine with regard to the time of day and day of the week in Poland, Germany, Great Britain and Italy. The goal of the study was to determine if there are any days of the week or hours when search for "suicide" and "depression" particularly increases. Numerous studies focusing not only on the seasonality of suicidal behavior, but also on the days of the week and hours, indicate that it is most often undertaken on Mondays in the night and early morning hours. The results of the research being the basis of this paper show a certain time coincidence: first, the increase in search interest for "suicide" and "depression" and then undertaking suicidal behavior (suicide and suicide attempts). Searching for terms "suicide" and "depression" usually took place (except in Italy) at weekends and most often in the late evening hours and at night. The conclusions from the research can be used in suicide prevention activities, for example in determining the hours of operation of individual helpline numbers.
抑郁症是企图自杀或自杀身亡者中最常见的疾病。研究综述表明，抑郁症治疗（包括心理教育）是预防自杀行为的主要因素之一。在本文中，我们研究了波兰、德国、英国和意大利谷歌搜索引擎中“抑郁症”和“自杀”这两个词条搜索兴趣在一天中的时间和一周中的日期方面的强化情况。该研究的目的是确定一周中的某些日子或某些时段搜索“自杀”和“抑郁症”的情况是否会特别增加。众多研究不仅关注自杀行为的季节性，还关注一周中的日期和时段，结果表明自杀行为最常发生在周一的夜间和凌晨时段。作为本文基础的研究结果显示出一定的时间巧合：首先是“自杀”和“抑郁症”搜索兴趣增加，然后是自杀行为（自杀和自杀未遂）的发生。搜索“自杀”和“抑郁症”词条的行为通常（意大利除外）发生在周末，且最常出现在深夜和夜间。该研究的结论可用于自杀预防活动，例如确定各个求助热线号码的运营时间。
