Every recommendation on this site is based on these sources. We summarize what families really need to know in everyday life.
AWMF Guideline (2023)
The first German guideline for the prevention of dysregulated screen media use in childhood and adolescence. Created by an interdisciplinary panel of experts.
Key Finding
It is not screen time alone that matters, but whether other areas of life (sleep, exercise, social contacts, school) are being displaced. The displacement principle is the central benchmark.
WHO – Gaming Disorder (ICD-11)
The World Health Organization recognized Gaming Disorder as an independent diagnosis in the ICD-11 in 2019. This marks a paradigm shift.
Key Finding
Central criteria are loss of control, increasing prioritization of gaming over other activities, and continuation despite negative consequences — for at least 12 months.
AAP – American Academy of Pediatrics
The AAP has published the most widely cited recommendations on screen time for children for years. Regularly updated.
Key Finding
Under 2 years: avoid screen media as much as possible (except video calls). For older children: set consistent limits, protect sleep and exercise, do not use media as a pacifier.
UNICEF – Children in a Digital World
UNICEF emphasizes both the opportunities and risks of digitalization for children worldwide and calls for a differentiated view instead of blanket condemnation.
Key Finding
Digital literacy and critical engagement are more important than time limits alone. Children need guidance, not just control. Access to digital media is also a question of equal opportunity.
Lancet Child & Adolescent Health (2019)
One of the largest studies on the relationship between screen time and child well-being. Over 40,000 participants.
Key Finding
Moderate screen time shows barely any negative effects. The dose-response relationship is weaker than often portrayed. Context (what, when, with whom) matters more than duration alone.
BZgA – Federal Centre for Health Education
The BZgA provides data on media use and problematic behavior among adolescents in Germany. Regular surveys (Drug Affinity Study).
Key Finding
About 6–8% of 12–17-year-olds show problematic social media use. For gaming, the rate is approximately 4–6%. Boys are more frequently affected in gaming, girls in social media.
