Summary

This trial tests whether a mobile health app called mTranS-C can improve sleep quality in adolescents who are at risk for depression and anxiety but do not yet have a psychiatric diagnosis. The app delivers a behavioral sleep intervention designed to address insomnia and delayed sleep phase. Researchers will measure changes in sleep quality and mood symptoms to see if improving sleep can help prevent mental health issues.
