Area of Science:

  • Adolescent mental health
  • Public health interventions
  • Digital well-being

Background:

  • Problematic Internet use significantly impacts adolescent mental health.
  • No previous randomized clinical trials have evaluated universal school-based interventions for this issue in Japan.
  • This study addresses the gap in evidence for effective school-based programs.

Purpose of the Study:

  • To assess the efficacy of a school-based educational program targeting problematic Internet use.
  • To evaluate the program's impact on Internet addiction, smartphone addiction, and usage time.
  • To provide data for developing future interventions for Japanese adolescents.

Main Methods:

  • A cluster-based randomized clinical trial involving 5312 students across 13 Japanese high schools.
  • Intervention group received 10 weekly standardized educational sessions; control group received standard curriculum.
  • Outcomes assessed using the Korean Scale for Internet Addiction (K-scale) and transtheoretical model for smartphone addiction and usage time.

Main Results:

  • The school-based program did not demonstrate significant improvement in Internet or smartphone addiction scores.
  • A significant discrepancy was observed in behavioral change status between groups.
  • The intervention failed to reduce problematic Internet or smartphone use among participants.

Conclusions:

  • The current school-based educational program is ineffective in mitigating Internet and smartphone addiction among Japanese adolescents.
  • Further research is crucial to develop and validate more effective interventions.
  • Targeted strategies are needed to address the mental health challenges associated with problematic Internet use in adolescents.
