Concept
The relationships between digital media use and mental health have been investigated by various researchers—predominantly psychologists, sociologists, anthropologists, and medical experts—especially since the mid-1990s, after the growth of the World Wide Web. A significant body of research has explored "overuse" phenomena, commonly known as "digital addictions", or "digital dependencies". These phenomena manifest differently in many societies and cultures. Some experts have investigated the benefits of moderate digital media use in various domains, including in mental health, and the treatment of mental health problems with novel technological solutions. The delineation between beneficial and pathological use of digital media has not been established. There are no widely accepted diagnostic criteria, although some experts consider overuse a manifestation of underlying psychiatric disorders. The prevention and treatment of pathological digital media use is also not standardised, although guidelines for safer media use for children and families have been developed. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and the International Classification of Diseases (ICD-11) do not include diagnoses for problematic internet use and problematic social media use; the ICD-11 include diagnosis for gaming disorder (commonly known as video game addiction), whereas the DSM-5 does not. Experts are still debating how and when to diagnose these conditions. The use of the term addiction to refer to these phenomena and diagnoses has also been questioned. Digital media and screen time have changed how children think, interact and develop in positive and negative ways, but researchers are unsure about the existence of hypothesised causal links between digital media use and mental health outcomes. Those links appear to depend on the individual and the platforms they use. Several large technology firms have made commitments or announced strategies to try to reduce the risks of digital media use.
