Sperimentale: NAVO:J Intervention Group
Participants in this single-arm group use the digital mental health platform NAVO:J for 17 weeks (17 sessions, once a week for approximately 40 minutes).
Each session includes app-based activities such as recommended mental health videos, tailored self-care solutions, self-assessments, mind coaching, and diary entries.
Mental health outcomes are assessed at baseline, mid-point (week 8), and post-intervention (week 17) using a single-group pre-post design.
|
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.

Change in Depression (PHQ-9)
Lasso di tempo: 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)
Lasso di tempo: 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.

|
Subjective mental health is measured using a self-report Visual Analog Scale (VAS) developed by the research team to multidimensionally assess adolescents' perceived mental health.
It consists of 9 items, each rated on an 11-point scale from 0 (not at all) to 10 (very much).
It is used as a supplementary measure of overall perceived mental health.
