Summary

A December 2025 study by van der Wal et al. in Current Psychology investigated the impact of social media on the mental health of 479 Dutch adolescents aged 14-18. The research, titled "Diverse platforms, diverse effects," used daily questionnaires over 100 days to track social media usage and three psychological dimensions: well-being, self-esteem, and friendship closeness. Key findings indicate that approximately 68% of subjects experienced "unity outcomes" with increased social media use, with nearly 60% of these being negative (two or more negative outcomes). However, 13.6% showed "disunity," a mix of positive and negative outcomes. Crucially, the study found significant variance based on the platform: TikTok, YouTube, and Instagram were generally associated with negative outcomes, while WhatsApp and Snapchat correlated with null or positive outcomes. The study is descriptive, not causal, and highlights the need for more granular research.

Key takeaway

For policymakers and platform designers addressing adolescent mental health, your focus should shift from broad social media bans or screen time limits to platform-specific design elements. Recognize that platforms like WhatsApp and Snapchat show different associations than TikTok or YouTube. Prioritize discouraging agency-reducing features such as autoplay and infinite scroll, and tailor interventions to account for the diverse psychological effects and individual experiences of young people, rather than applying rigid, one-size-fits-all regulations.

Key insights

Social media's mental health impact on teens varies significantly by platform and individual, often showing negative associations.

Principles

• Platform-specific design influences psychological outcomes.
• Mental health effects are not uniform across individuals.

Method

A 100-day daily questionnaire study tracked 479 adolescents' social media use and three psychological dimensions (well-being, self-esteem, friendship closeness) to assess within-person changes and platform-specific effects.

In practice

• Analyze platform-specific usage patterns.
• Consider individual psychological baselines.
• Focus on specific design features, not just screen time.

• Social Media Harms
