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

Condition(s) studied

Investigational drug(s) / intervention(s)

NAVO:J (digital mental health platform): Participants use NAVO:J, a digital mental health platform developed for adolescents, delivered as a structured group intervention over 17 weeks (17 sessions, once weekly, approximately 40 minutes each). The platform provides algorithm-based recommended videos, 12 tailored "mind solutions" based on emotional-behavioral characteristics, self-assessments (personality, depression, anxiety, stress, self-esteem, smartphone use), expert-supported community features, mind coaching, growth tracking across 10 adolescent mental health indicators, and a mood diary. Sessions are facilitated weekly by trained researchers following a standardized manual.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Change in Depression (PHQ-9) — Baseline, week 8 (mid-point), week 17 (post-intervention)
  Depression is measured using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), based on the DSM-IV criteria for major depressive disorder, assessing symptoms experienced over the past two weeks. The scale consists of 9 items rated on a 4-point Likert scale (score range: 0-27). Higher scores indicate more severe depressive symptoms. Change is assessed by comparing scores at baseline, mid-point, and post-intervention.
• Change in Resilience (CD-RISC-10) — Baseline, week 8 (mid-point), week 17 (post-intervention)
  Resilience is measured using the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), a self-report measure of an individual's ability to recover and adapt under adversity or stress. Each item is rated on a 5-point Likert scale (score range: 0-40). Higher scores indicate greater resilience. Change is assessed by comparing scores at baseline, mid-point, and post-intervention.
