NCT ID NCT04909203
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested a paired smartphone app called iKinnect2.0 for teenagers aged 15–21 who are involved in the juvenile justice system and at risk for suicide. The app aims to help youth and their parents communicate better, manage distress, and prevent self-harm. Fifty-six parent-teen pairs used either the iKinnect2.0 app or a control app for 16 weeks, and researchers tracked changes in suicidal thoughts, coping skills, and family functioning.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- iKinnect2.0 mobile phone app
- What this could lead to
- If it works, this could provide a practical tool to help at-risk youth and their families manage suicidal thoughts and behaviors.
- What could go wrong
- This is a small, early-stage trial with only 56 participants, so results may not apply broadly. The app's effectiveness is unproven, and it relies on consistent use by both youth and parents.
