Key Takeaway

Note that voice- and text-based crisis interventions consistently reduce suicidal ideation and psychological distress.

This scoping review synthesized evidence from 24 studies regarding low-threshold secondary and tertiary suicide prevention measures, including voice-based, text-based, outreach, and web-based interventions for adults with suicide-related thoughts and behaviors. The review aimed to evaluate the efficacy of these technologies in reducing suicidal ideation and psychological distress.

Voice-based (9 studies) and text-based (7 studies) crisis interventions consistently demonstrated reductions in suicidal ideation and psychological distress. In contrast, outreach messages (3 studies) and web-based educational or counseling measures (5 studies) yielded more heterogeneous findings, though potential benefits were indicated. A moderated peer-to-peer forum was noted as an exception to the consistent reductions seen in other modalities.

Several limitations were identified in the current evidence base. The findings for web-based and outreach measures were less consistent than those for voice and text. Furthermore, the evidence for voice- and text-based interventions primarily demonstrates short-term effects. These findings suggest that while voice and text interventions have a growing evidence base, the long-term impact and the specific efficacy of web-based tools require further investigation.

A review of 24 studies looked at how different types of technology and outreach can help adults experiencing suicide related thoughts and behaviors. The researchers looked at voice based, text based, outreach messages, and web based educational tools to see how they affected psychological distress.

The findings showed that voice and text based crisis interventions consistently helped reduce suicidal thoughts and distress. However, these specific methods are primarily known to provide short term effects. Other methods, such as outreach messages and web based counseling, showed promising results but were less consistent across the different studies.

Because the evidence for web based and outreach tools is still varied, it is hard to say exactly how effective they are long term. While these technologies offer new ways to reach people in need, they are not a replacement for standard care. These findings highlight how digital tools can support immediate crisis intervention.

What this means for you:

Voice and text crisis interventions show consistent short term results in reducing suicidal thoughts and distress.

Common questions

Are voice and text interventions effective for suicide prevention?

Yes, the review of 24 studies found that voice based and text based crisis interventions consistently showed reductions in suicidal ideation and psychological distress. However, these types of interventions are primarily known to provide short term effects for the people using them.

What are the results for web based and outreach measures?

The findings for outreach messages and web based educational or counseling measures were promising but less consistent. While these methods show potential benefits, the evidence for them is more varied compared to voice and text options.

Who do these interventions help?

These interventions were studied in adults who are experiencing suicide related thoughts and behaviors. They are designed as low threshold measures to provide support and reduce psychological distress during a crisis.

IntroductionSuicide rates remain persistently high in many regions worldwide, including Germany. The 2024 German National Suicide Prevention Strategy emphasizes the strengthening of evidence-based approaches. In this context, a comprehensive synthesis of low-threshold secondary and tertiary suicide prevention measures for adults is required.MethodsThis scoping review set out to address this need and followed established methodological guidance and the PRISMA-ScR reporting guidelines. PubMed and Web of Science were searched on September 1, 2025, for studies published from January 1, 2005, onwards. To be eligible for inclusion, studies needed to examine low-threshold secondary or tertiary suicide prevention measures targeting adults with suicide-related thoughts and behaviors (STBs). Interventions focusing on primary medical care, psychotherapy, pharmacotherapy, gatekeepers and means restriction were excluded.ResultsOut of 1,897 records, 24 studies met the inclusion criteria. Most studies investigated voice-based (n = 9; 37.5%) and text-based (n = 7; 29.2%) crisis interventions within suicide prevention lifelines. These interventions consistently demonstrated reductions in suicidal ideation and psychological distress, with one exception: a moderated peer-to-peer forum. Outreach messages (n = 3; 12.5%) and web-based educational (and counseling) measures (n = 5; 20.8%) showed promising but more heterogeneous findings. Outcomes indicated potential benefits, though the evidence was less consistent.DiscussionThe findings suggest that voice- and text-based crisis interventions are supported by a growing evidence base, primarily demonstrating short-term effects. Web-based educational (and counseling) measures and outreach messages, while heterogeneous, show potential for individuals with STBs through the use of emerging technologies. Future research should examine mechanisms of action, long-term outcomes, and employ randomized controlled trial designs (where feasible) to strengthen the evidence base.Systematic review registrationhttps://doi.org/10.17605/OSF.IO/K2B83.
