PHILADELPHIA (CBS) - A recent study sponsored by SecurEnvoy has found that since 2008, the amount of people who fear being without a mobile phone has grown from 53 percent to 66 percent.

The term nomophobia, meaning the fear of being out of mobile phone contact, was first coined by British researchers in 2008.

The 2012 study, which surveyed 1,000 people, found that people not only fear being without a cell phone, but almost half of respondents said they would be upset if their partner looked through their messages.

This study also found that those who are 55 and older are the third most nomophobic group, after ages 18-24, who were first, and ages 25-34.
