周一的自杀未遂率和死亡率最高，并且在早上或下午早些时候发生的频率更高，这表明自杀行为每周和每日都有变化。目前尚不清楚社交媒体上与自杀相关的帖子是否也存在类似的时间趋势。我们的目的是确定 Reddit 论坛 SuicideWatch 上发帖模式的时间和每日变化，SuicideWatch 是一个为可能有自杀风险或认识有自杀风险的人提供的在线社区。我们使用时间序列分析将 2008 年 12 月 1 日至 2015 年 8 月 31 日期间的 90,518 个 SuicideWatch 帖子的日期和时间戳与 (i) 最常订阅的常规 subreddit、AskReddit 上的 6,616,431 个帖子和 (ii) 其中由 SuicideWatch 作者发布的 66,934 个 AskReddit 帖子进行了比较。 SuicideWatch 上周一的帖子比例最高。观察到明显的日变化，在清晨（2:00–5:00）出现峰值，随后在上午晚些时候/下午早些时候（11:00–14:00）下降至低谷。相反，控制数据中帖子量最高的时段是 20:00–23:00。 SuicideWatch 上的帖子最常出现在周一：这一天与自杀风险最相关。 SuicideWatch 帖子的清晨高峰早于一天中自杀未遂和死亡最常发生的时间。对这些每周和每日节律的进一步研究应该有助于在最需要时为目标人群提供支持和自杀预防干预措施。在线版本包含可在 10.1186/s12888-021-03268-1 获取的补充材料。
Rates of suicide attempts and deaths are highest on Mondays and these occur more frequently in the morning or early afternoon, suggesting weekly temporal and diurnal variation in suicidal behaviour. It is unknown whether there are similar time trends on social media, of posts relevant to suicide. We aimed to determine temporal and diurnal variation in posting patterns on the Reddit forum SuicideWatch, an online community for individuals who might be at risk of, or who know someone at risk of suicide. We used time series analysis to compare date and time stamps of 90,518 SuicideWatch posts from 1st December 2008 to 31st August 2015 to (i) 6,616,431 posts on the most commonly subscribed general subreddit, AskReddit and (ii) 66,934 of these AskReddit posts, which were posted by the SuicideWatch authors. Mondays showed the highest proportion of posts on SuicideWatch. Clear diurnal variation was observed, with a peak in the early morning (2:00–5:00 h), and a subsequent decrease to a trough in late morning/early afternoon (11:00–14:00 h). Conversely, the highest volume of posts in the control data was between 20:00–23:00 h. Posts on SuicideWatch occurred most frequently on Mondays: the day most associated with suicide risk. The early morning peak in SuicideWatch posts precedes the time of day during which suicide attempts and deaths most commonly occur. Further research of these weekly and diurnal rhythms should help target populations with support and suicide prevention interventions when needed most.
