This randomized clinical trial evaluated the effectiveness of cognitive behavioral therapy (CBT) versus a media literacy intervention for preventing gaming disorder and unspecified internet use disorder among adolescents. Conducted in 44 secondary schools in Germany, the study found that high-risk adolescents receiving CBT had significantly lower symptom severity at 12 months compared to those receiving media literacy training, with a mean Modified Video Game Dependency Scale score of 14.7 vs 17.7.

Key findings

  • High-risk adolescents receiving CBT had a mean Modified Video Game Dependency Scale score of 14.7 compared to 17.7 for media literacy.
  • The within-group Cohen d for CBT was -0.91, indicating a large effect size.
  • No significant differences in outcomes were observed in the total sample between the two interventions.
  • Secondary outcomes did not differ significantly between the CBT and media literacy groups.

Why it matters

Understanding effective interventions for gaming and internet use disorders is crucial for mental health professionals. This study highlights the potential of CBT in reducing symptoms among at-risk youth, informing prevention strategies.
