Cross-National Replication: Platform Design Features and Adolescent Wellbeing Across 80 Countries (PISA 2022)

Key Points

• To evaluate how platform design features affect adolescent wellbeing across 80 countries using PISA 2022 data.
• Analyzed individual-level microdata from 613,744 students across 80 countries.
• Applied feature-based platform scoring methodology from prior studies to assess social media use and wellbeing.
• Conducted cross-national ecological analysis while controlling for GDP.
• Social media use is associated with lower life satisfaction (p=0.007), with girls being 5.6 times more affected than boys.
• Platform design features significantly predict adolescent wellbeing in Western Europe (r=-0.648, p=0.017).
• Findings persist even after adjusting for GDP.
