What this trial studies
This observational study surveys individuals using the Zelfmoordlijn 1813 chat service to understand their experience and any changes in mood or thoughts after the interaction. Participants aged 16 and older complete brief questionnaires prior to and following their chat, with voluntary participation and no change to standard care. Data will describe user experience and potential associations between chat conversations and changes in suicidal ideation or distress. The study is led by Ghent University in collaboration with the Flemish Centre of Expertise in Suicide Prevention and does not include any intervention beyond routine chat support.
Why it matters
Potential benefit: Results could inform how chat-based crisis support affects suicidal thoughts and guide improvements to online crisis services.
How similar studies have gone: Previous work has explored phone-based interventions; this study addresses chat interactions, an area with limited but growing evidence.
