This study aims to evaluate the validity and effectiveness of NEMO-I (Neuro-cognitive Emotion Monitoring-Intervention), a mobile application designed to help adolescents monitor and manage their cognitive and emotional functioning in everyday settings. NEMO-I delivers evidence-based psychological techniques-such as mindfulness, self-regulation training, and emotion monitoring-in a gamified format consisting of seven brief activities that users can complete at home in about 10 minutes each. A total of 140 middle and high school students will participate. Participants will complete standardized neuropsychological and psychological assessments before and after the intervention period. During the 21-day intervention period, participants will use the NEMO-I application at home each day at their convenience (a minimum of 10 minutes per day is recommended). By comparing pre- and post-intervention assessment results, this study seeks to determine whether the application produces meaningful benefits for adolescent mental health and to establish its suitability as a digital mental health tool.
