Estonian internet users aged 12 to 16 have satisfactory digital skills and mental well-being indicators compared with other European countries, while excessive internet use predicts lower levels of mental well-being in young people. The middle-aged and older population (aged 50 and over) tend to have problems with digital skills, while people with better digital skills feel less lonely and depressed. Although the factors affecting mental well-being are different in these two age groups, how and in what context digital skills are acquired is essential in both cases.
