Nomophobia is a proposed name for the phobia of being out of cellular phone contact. It is, however, arguable that the word “phobia” is misused and that in the majority of cases it is another form of anxiety disorder.
Although nomophobia does not appear in the current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), it has been proposed as a “specific phobia”, based on definitions given in the DSM-IV. According to Bianchi and Philips (2005) psychological factors are involved in the overuse of a mobile phone. These could include low self-esteem, when individuals looking for reassurance use the mobile phone in inappropriate ways, and extroverted personality, when naturally social individuals use the mobile phone to excess. It is also highly possible that nomophobic symptoms may be caused by other underlying and preexisting mental disorders, with likely candidates including social phobia or social anxiety disorder, social anxiety, and panic disorder.
