Overview

Infodemiological analysis shows seasonality in suicide searches and rising demand for hotline resources globally, suggesting improved visibility strategies.

Key Points

  • This research aims to analyze temporal trends and geographic patterns in online searches related to suicide and crisis hotlines.
  • Analyzed global Google search trends for 'Suicide' and 'Crisis Hotline' from 2004–2025
  • Applied Seasonal and Trend decomposition using Loess (STL) and Autoregressive Integrated Moving Average (ARIMA) forecasting
  • Utilized K-means clustering to identify country-level search volume patterns
  • Conducted Pearson correlations and cross-lagged correlations for temporal associations.
  • Identified significant spikes in suicide searches during specific years: 2009–2010, 2014, 2017–2018, and 2020–2021
  • Crisis hotline searches increased markedly from the late 2010s, particularly during the COVID-19 pandemic
  • Found significant seasonality in suicide search trends, though not in crisis hotline searches
  • Cross-lagged analysis revealed a temporary association before adjustment revealed only a contemporaneous link.
