In this study we coined the term smartphone addiction (SA) to describe consumer’s addictive
disorder. We followed the definition of SA according to Beard(2005)’s approach [5]. He insists that
“an individual is addicted when an individual’s psychological state, which includes both mental and
emotional states, as well as their scholastic, occupational and social interactions, is impaired by the
overuse of the medium.” By applying this understanding, SA can be defined as a state of being
enslaved to smartphone and its related service. It also can be described as uncontrollable and damaging
use of smartphone and is recognized as a related service usage disorders.
