Digital media use and mental health

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 and rise of text messaging. 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 standardized, although guidelines for safer media use for children and families have been developed. The 2013 fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (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 includes a diagnosis for gaming disorder (commonly known as video game addiction), whereas the DSM-5 does not. Debate over how and when to diagnose these conditions is ongoing as of 2023. The use of the term addiction to refer to these phenomena and diagnoses has been questioned.

Digital media and screen time amongst modern social media apps such as Instagram, Tiktok, Snapchat and Facebook have changed how children think, interact and develop in positive and negative ways, but researchers are unsure about the existence of hypothesized 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.
