A study of more than 2mn people’s internet use found no “smoking gun” for widespread harm to mental health from online activities such as browsing social media and gaming, despite widely claimed concerns that mobile apps can cause depression and anxiety.
Researchers at the Oxford Internet Institute, who said their study was the largest of its kind, said they found no evidence to support “popular ideas that certain groups are more at risk” from the technology.
However, Andrew Przybylski, professor at the institute — part of the University of Oxford — said that the data necessary to establish a causal connection was “absent” without more co-operation from tech companies. If apps do harm mental health, only the companies that build them have the user data that could prove it, he said.
