Summary

This study tests whether a mobile app called NEMO-I can help adolescents monitor and improve their emotional and cognitive health. The app offers seven brief, gamified activities—like facial expression imitation, singing, and mindfulness—that take about 10 minutes each day. Researchers will compare before-and-after assessments in 140 middle and high school students to see if the app reduces symptoms of depression and anxiety and improves attention and thinking skills.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
NEMO-I (Neuro-cognitive Emotion Monitoring-Intervention), a gamified mobile application with brief psychological activities
What this could lead to
If effective, NEMO-I could provide a convenient, low-cost digital tool to help adolescents manage stress, anxiety, and mood in everyday life.
What could go wrong
This is a small, early-stage validation study with 140 participants, so results may not apply broadly. The app relies on self-reported use and may not work for everyone.
