This study was carried out to investigate the digital addiction (DA) level of the university students according to their purposes for using digital tools. 527 students studying at the faculties of education of Erzincan, Dicle, and Siirt Universities participated this study in which general survey model was used. A form was used to reveal for which purpose and how often the students used digital tools. The DA levels of the students were found out by the Digital Addiction Scale. According to the frequencies of the students' using digital tools for participating social media, playing games, communicating, and shopping, the DA scores were found to differ significantly for those who used digital tools for these purposes more frequently. The DA scores of the students who used digital tools a lot for research were significantly lower than the scores of the students using tools less for this purpose. It was also found that the DA scores of the students who used digital tools for watching films and listening to music with different frequencies did not differ from each other significantly. The study has shown that while the frequent use of digital tools for participating social media is highly effective on digital addiction, the frequent use of digital tools for games, communication, research, and shopping has a low effect on digital addiction.
