NAVO:J School-Based Group Intervention for Adolescent Mental Health

Effects of a School-Based Group Intervention Using the Digital Mental Health Platform NAVO:J on Adolescent Mental Health

The purpose of this study is to determine and verify whether a school-based group intervention using the digital mental health platform NAVO:J can effectively improve the mental health of adolescents-particularly reducing depression, anxiety, and stress while enhancing resilience.

NAVO:J is a digital mental health platform designed to promote adolescent mental health.

The intervention will be conducted as a single-group pre-post design with students (N = 250 subjects) who apply for the Level 2-2 (group intervention) program.

The intervention period will be 17 weeks (17 sessions, once a week for about 40 minutes), with a mid-point evaluation at week 8 and a post-intervention evaluation at week 17.

Inclusion Criteria:

• Students who apply for the group intervention program
• Possession of an internet-enabled smartphone
• Consent to study participation by both the participant and their legal guardian

Exclusion Criteria:

• Inability to install or run "NAVO:J" on the participant's smartphone
• Current participation in another interventional study
• A medical condition severe enough to preclude the intervention or outcome assessment
• Judged by the researcher to be unlikely to participate cooperatively through the end of the study
