Answer given by Mr Andriukaitis on behalf of the European Commission
The Commission is aware that the World Health Organisation (WHO) has included gaming disorder as a diagnosable condition in the 11th edition of the International Classification of Diseases.
The report ‘Prevention of Addictive Behaviours’ published by the European Monitoring Centre for Drugs and Drugs Addictions covers also behavioural addictions, such as gambling, and includes prevention measures and recommendations.
Measures to prevent and treat this kind of addiction are the responsibility of the Member States. The Commission supports them e.g. through the ‘Adocare’ preparatory action which assessed problems adolescents can encounter when dealing with new technologies, including Internet use, gaming, mobile phone use, addiction to new media, cyberbullying and sexting.
In addition, the Commission has recently launched the Best Practice Portal with the objective of identifying, disseminating and transferring best practices to support Member States to meet the United Nations Sustainable Development Goals (particularly target 3.4) and the WHO nine targets on non-communicable diseases. This portal is a ‘one-stop shop’ for consulting best practices and to submit best practices for assessment. All practices in the area of health promotion, disease prevention and management of non-communicable diseases are welcome, including those to prevent video game addition.
