Cell phone addiction is a very real phenomenon. Research has shown some people experience serious negative physiological effects when separated from their phones. There’s even a scientific term for that separation anxiety: nomophobia. (You just can’t make this stuff up … unless you’re a scientist, apparently.)

Of course, while few people will admit to being addicted to their phones, denial is often a hallmark symptom of addiction. (Gotcha!)

In an attempt to get a start on diagnosing the problem — nomophobia isn’t recognized in the current DSM V — social psychologists from the University of Iowa have devised a 20-item questionnaire, shared recently by Science of Us, designed to measure a person’s self-reported nomophobia.

Try out the questionnaire below to see how you might answer.

1. I would feel uncomfortable without constant access to information through my smartphone.
2. I would be annoyed if I could not look information up on my smartphone when I wanted to do so.
3. Being unable to get the news (e.g., happenings, weather, etc.) on my smartphone would make me nervous.
4. I would be annoyed if I could not use my smartphone and/or its capabilities when I wanted to do so.
5. Running out of battery in my smartphone would scare me.
6. If I were to run out of credits or hit my monthly data limit, I would panic.
7. If I did not have a data signal or could not connect to Wi-Fi, then I would constantly check to see if I had a signal or could find a Wi-Fi network.
8. If I could not use my smartphone, I would be afraid of getting stranded somewhere.
9. If I could not check my smartphone for a while, I would feel a desire to check it.
