Europe’s Research on Internet Addiction Just Got Deeper—And It Explains Teen Disengagement Better

A significant new study led by Professor Matthias Brand at the University of Duisburg-Essen, published May 5, 2026, strengthens the empirical foundation of the I-PACE (Interaction of Person-Affect-Cognition-Execution) model—one of Europe’s most influential frameworks for understanding behavioral addictions.

The research addresses a pressing question that educators, parents, and policymakers across the EU struggle with daily: why is it so difficult for young people to disengage from screens, even when they recognize the harm?

What the Research Covers

The study examines problematic usage patterns across multiple digital contexts: excessive gaming, intensive social media use, compulsive online shopping, and pornography consumption. Rather than treating these as isolated behaviors, the research investigates the underlying neuropsychological mechanisms that make disengagement difficult.

Funded through the European Union’s Horizon Europe research and innovation programme, the BootStRaP (Building Resilience and Reducing Digital Risk for Teenagers and Young People) project unites scientists from 14 countries and 22 institutions. This pan-European scope is crucial: it means findings aren’t culturally isolated or dependent on single-nation regulatory contexts.

Why This Matters for European Digital Policy

The I-PACE model itself has become foundational to how Europe approaches digital wellness—it’s cited in policy discussions from Ireland to the Nordic nations. Brand’s new work directly strengthens this evidence base just as the EU implements the Digital Services Act and considers further digital literacy interventions.

For Ireland specifically, this research arrives at a critical moment. As digital device adoption among Irish teenagers remains above EU averages, understanding the mechanisms of addictive engagement—not just the behavioral symptoms—allows for more targeted prevention and intervention strategies.

Practical Implications for Builders and Educators

The research doesn’t just identify problems; it advances understanding of how digital experiences interact with individual psychology and cognition. This has direct implications:

  • Platform designers can better understand which features create difficulty in disengagement
  • Educational institutions can develop more nuanced digital literacy programs based on psychological mechanisms rather than generic screen-time warnings
  • Mental health professionals gain empirical grounding for interventions targeting behavioral addictions
  • Policymakers can design more evidence-informed regulations around platform design and youth protection

Open Questions

While the study advances the I-PACE model, several tensions remain unclear:

  • How do findings differ across individual countries with different regulatory approaches (e.g., comparing strict EU frameworks vs. less regulated markets)?
  • What intervention strategies most effectively target these neuropsychological mechanisms without requiring individual clinical assessment?
  • How do cultural attitudes toward digital use across Europe influence the strength of these mechanisms?

The BootStRaP project’s scale offers potential to answer these—but published findings will need careful monitoring as the broader research programme unfolds.

What’s Next

Expect this research to influence upcoming EU digital youth protection frameworks and Irish educational policy discussions around digital wellness. The evidence-based approach—grounded in psychological mechanisms rather than moral panic—represents a maturation of how Europe discusses internet addiction at the policy level.
