Are you a nomophobe? If you're wondering how to respond to that question, an Iowa State University study can help you find the answer. ISU researchers have developed a questionnaire to help you determine if you suffer from nomophobia or a fear of being without your mobile phone.

Caglar Yildirim, lead author of the study and a Ph.D. student in human computer interaction, and Ana-Paula Correia, an associate professor in ISU's School of Education, identified four dimensions of this modern-day phobia. The study was published in the journal Computers in Human Behavior. Watch this video to learn more about nomophobia and then answer the questions below to see if you are nomophobic.
