  • Background

    Recent research highlights the dynamics of suicide risk, resulting in a shift toward real-time methodologies, such as ecological momentary assessment (EMA), to improve suicide risk identification. However, EMA’s reliance on active self-reporting introduces challenges, including participant burden and reduced response rates during crises. This study explores the potential of Screenomics—a passive digital phenotyping method that captures intensive, real-time smartphone screenshots—to detect suicide risk through text-based analysis.

    Method

    Seventy-nine participants with past-month suicidal ideation or behavior completed daily EMA prompts and provided smartphone data over 28 days, resulting in approximately 7.5 million screenshots. Text from screenshots was analyzed using a validated dictionary encompassing suicide-related and general risk language.

    Results

    Results indicated significant associations between passive and active suicidal ideation and suicide planning with specific language patterns. Detection of words related to suicidal thoughts and general risk-related words strongly correlated with self-reported suicide risk, with distinct between- and within-person effects highlighting the dynamic nature of suicide risk factors.

    Conclusions

    This study demonstrates the feasibility of leveraging smartphone text data for real-time suicide risk detection, offering a scalable, low-burden alternative to traditional methods. Findings suggest that dynamic, individualized monitoring via passive data collection could enhance suicide prevention efforts by enabling timely, tailored interventions. Future research should refine language models and explore diverse populations to extend the generalizability of this innovative approach.

  • Summary

    Wessex Tales is Thomas Hardy’s first collection of stories. Published as two volumes in 1888, it contains some of his best-known short works, including ‘The Three Strangers’, ‘The Withered Arm’ and ‘Fellow-Townsmen’. The longest story in the collection, ‘The Distracted Preacher’, is an exciting tale of smuggling on the Dorset coast based on the recollections of Hardy’s family. The Cambridge copy-text is the first edition of Wessex Tales, but it also includes Hardy’s story ‘An Imaginative Woman’, which was added later in the 1896 Osgood, McIlvaine edition. As with all volumes in the Cambridge Edition, full information on the publication history of the text is provided, along with a complete record of substantive variants. Illustrations include frontispieces for the first American edition along with those for the Osgood, McIlvaine and Wessex Editions. All of the illustrations for ‘An Imaginative Woman’ that appeared with its original publication in the Pall Mall Magazine are also reproduced.
