Mobile devices are altering family life in Mexico, according to a first-of-its-kind study conducted by the USC Annenberg School for Communication and Journalism and Common Sense that examines device use, habits, and attitudes of Mexican teens and their parents. More Mexican parents expressed concern about their teens' use of mobile devices, and more teens reported feeling distracted and "addicted" to their phones than families in three other countries: the United States, Japan, and the United Kingdom.
