National Public Radio reports that researchers appear divided over the effect of screen time and social media on teens' -- particularly girls' -- mental health. Jean Twenge, a professor of psychology at San Diego State University, says social media in particular may be causing anxiety among teens, however others say that her data is skewed. Critics state smartphone use is almost ubiquitous among teenagers today, while only a small minority report mental health problems, so simply knowing that a teenager uses a smartphone (even for many hours a day) cannot reliably predict that the teenager will become depressed. Factors such as genetics or the presence of childhood trauma can serve as much larger predictors.

So why should the average parent worry about this scientific controversy? Because, one critic says, when parents simply demonize phones, "there's less of a communications channel" about what teens are encountering online. A parent's opportunity to mentor or support positive uses of media is replaced by "confrontation on a day-to-day basis." Well-meaning parents, wrongly believing the phone to be as risky as a cigarette or a beer, may actually be making their children's lives harder by fighting with them about it.
