Smartphones working like a computer are much more than just classic mobile or cell phones used to communicate as they offer all the possibilities of computer and internet technology in our palms. By means of features they have and new applications developed every day, smartphones are used for a wide variety of purposes including but not limited to communicate with others, access to internet, use social networks, take and share photos and videos, shopping, play games, navigation and so on. Although they have the potential to improve people's daily life, work and education, excessive and uncontrolled use might bring addictive behaviors. This study aimed to explore the prevalence of smartphone addiction among a group of Turkish university students. The study was designed as a survey research within the quantitative research paradigm. Participants were 101 university students studying at major state university in Türkiye. Data were collected through a questionnaire form including Turkish version of the Smartphone Addiction Scale-Short Version. The results indicated that participants' mean scores were very close to the cut-off points for smartphone addiction. Individual analysis of scores indicated that almost half of the male and female participants were at risk of addictive behavior. The prevalence of smartphone addiction was not dependent on participants' gender and age. [For the complete proceedings, see ED672800.]
