Internet gaming disorder is defined as a persistent and recurrent engagement in Internet gaming which results in significant distress. Internet gaming disorder has become a global public health issue. It has been included in the updated version of the Diagnostic and Statistical Manual Disorders (DSM-5) and the International Classification of Diseases (ICD-11).

„Gambling involves risking something of value in a game of chance in hopes of obtaining something of greater value.<…> Online gambling closely relates to internet gaming in that the flashing lights and engaging game play keep the player glued to the screen awaiting the next attractive sound or visual splendor.“

“Cyberchondria is a pattern of excessive searching on the Internet for medical or health-related information with the following features: A) Searching is compulsive, hard to resist and serves the purpose of seeking reassurance; B) Initial relief, if obtained, through online searching is short-lived and anxiety or distress usually worsens during these searches and persists afterwards; C) Online searching takes precedence over other interests or daily activities and continues or escalates despite the occurrence of negative consequences associated with the searching.”

“Today, social media (e.g., Instagram, Facebook, YouTube, Twitter) are used by billions of people worldwide, and are transforming communication, social interaction, and learning. <…> the symptoms of problematic social media use are viewed as similar to those of other behavioral addictions and substance use disorders, and include salience, referring to the experience that a specific behavior becomes an extremely important activity in the person’s life and dominates their thinking, feelings and behaviors; mood modification, referring to the subjective experiences that people report as a consequence of engaging in the specific behavior (e.g. a tranquillizing and/or distressing feeling); tolerance, referring to the process whereby increasing amounts of the specific behavior are required to achieve the former reinforcing effects (or same amount generates fewer/smaller effects); withdrawal symptoms, referring to unpleasant feelings and/or physical effects which occur when the specific behavior is ceased or suddenly reduced; conflict, referring to struggles between the addicted individual and other people (interpersonal conflict) or within the individuals themselves (intrapsychic), which are related to the specific behavior; and relapse, referring to the tendency to reinstate the specific behavior after its cessation (even after many years).”

“Citizens and scientists can work together to improve the collective well-being, if citizens are inspired to help the advancement of science, and researchers motivated to listen to the voices of citizens. The benefits of such collaboration are increasingly recognized by both citizens and scientists, as reflected in the growing number of related publications and initiatives. This is especially relevant for emerging areas of research, where early involvement of citizens could help to envision, prioritize, and plan prospective studies. The Problematic Usage of the Internet (PUI) is one such area <…>.”
