The kids are all right. But the parents?

Since 2016, adults have grown much more concerned about the time they spend on mobile devices even as their teenage children have grown far less worried about their own use, according to a new report from Common Sense Media, a nonprofit children’s advocacy and media ratings organization.

“If you’re concerned about your own device use, which an increasing number of parents are, then you ought to be able to impart that wisdom to your kids,” said James P. Steyer, the organization’s chief executive. “That’s your job.”

The report, released on Wednesday and based on surveys of 500 pairs of parents and teenagers, found that both groups have a complicated relationship with the devices — and, of course, with each other.

Most parents worry that their kids are addicted to the devices, but about four in 10 teenagers have the same concern about their parents.
