Teens have cell phones with access to the internet; tablets and mini-tablets with access to the internet; laptops and desktop computers.

Everywhere you go you see people with cell phones: doctor’s office, restaurants, school events, the mall, airplanes etc.

Communication Addiction Disorder is a behavior disorder related to the necessity of being in constant communication with other people, even when there is no practical necessity for such communication.

Communication Addiction Disorder may be linked to Internet Addiction Disorder (IAD) which is excessive internet use. Neither of these ‘disorders’ is an official diagnosis but there has been much discussion among professionals for inclusion in the Diagnostic and Statistical Manual of Mental Disorders, often referred to as the DSM, which is published by the American Psychiatric Association. They may be included at some point in the future.

Users become addicted to one-on-one/group communication in the form of social support, relationships and entertainment.

It would seem that teenagers would be highly susceptible to a Communication Addiction Disorder since cell phones are their main source of communication.
