Think you’re addicted to your phone?

Can you remember the last time you were without your cellphone for more than an hour?

If you’re someone who depends on your smartphone for weather updates, news articles and the never-ending feeds of social media, chances are you’ve probably experienced nomophobia — the term used to describe the separation anxiety you feel when you’re away from your mobile phone.

Nomophobia (“nomo” meaning no mobile) isn’t uncommon among Americans. In fact, 84 percent of Americans say they can’t go a single day without their phone, and 50 percent say they sleep with their phone next to them, according to a study from Time magazine.

Not sure if you’re addicted? Psychologists from Iowa State University say they’ve developed a questionnaire to test just how addicted you really are.

The list of 20 questions, originally posted by New York Magazine, is listed below. The more frequently you answer “yes” to the questions, the greater your level of nomophobia.
