The present study investigates the roles of smartphone usage, self-regulation, general self-efficacy and cyberloafing in smartphone addiction. We conducted an online survey which received responses from 598 participants attending a public university in Ankara, Turkey. The results showed that both the duration of smartphone usage and cyberloafing positively affected smartphone addiction. The effect of self-regulation on smartphone addiction was negative and significant. In addition, neither self-regulation nor general self-efficacy had an effect on cyberloafing. Research results are discussed within the context of the effect of smartphone addiction on learning environments and individuals. (C) 2016 Elsevier Ltd. All rights reserved.
