The review of the relevant literature revealed that more research is warranted to
investigate nomophobia as a theoretical construct (King et al., 2013; King et al., 2014). Given
that the majority of measures have been developed based on some substance use and addiction
criteria, the need for qualitatively exploring the problematic mobile phone use in general and
nomophobia in particular is apparent on the grounds that such an exploration through interviews
can strengthen the validity of items included in measures.
