Girls and boys might be more vulnerable to the negative effects of social media use at different times during their adolescence, say an international team of scientists. The researchers show that, in UK data, girls experience a negative link between social media use and life satisfaction when they are 11-13 years old and boys when they are 14-15 years old. Increased social media use again predicts lower life satisfaction at age 19 years. At other times the link was not statistically significant.
