Screen time: Based on the response to the question, “On most weekdays, how many hours do youspend a day in front of a TV, computer, cellphone or other electronic device watching programs,playing games, accessing the internet, or using social media?” Respondents were instructed not toinclude time spent for schoolwork. Response options were “Less than 1 hour; 1 hour; 2 hours;3 hours; 4 or more hours.”
I'll have to look further into how phones versus televisions and other devices affect total screen time.
