Mobile Intervention for Suicidal Thoughts (MIST) for Veterans

This study is testing a new mobile app called MIST (Mobile Intervention for Suicidal Thoughts) for Veterans who are having suicidal thoughts. The MIST app is designed to help change certain ways of thinking that can contribute to suicide risk. Researchers want to see if the MIST app is a practical and helpful addition to standard care, which includes safety planning (a written list of coping strategies) and ongoing care with your current providers. The study plans to enroll 50 Veterans. Success in this study means that enough participants join, complete the MIST app intervention, and are satisfied with using the app. The current status of this study is unclear.

Study design
This is a pilot randomized controlled trial, meaning participants will be randomly assigned to receive either the MIST app plus usual care and safety planning, or just usual care and safety planning. The study aims to enroll 50 participants.
What's involved
Participants in the MIST group will be asked to use the intervention 5 times a week for 4 weeks. There will be a post-treatment visit about one month after enrollment.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed through study completion, which is approximately 18 months, with a post-treatment visit about one month after enrollment.
