Self-regulation has assumed an important role in online gaming addiction. Although the role of self-regulation has received increasing scholarly attention in the past decade, research on self-regulation remains new in the information systems literature. There is also a lack of understanding of how technological design features can enhance one's self-regulation and thus prevent online gaming addiction. Therefore, we attempt to bridge these research gaps by identifying technological design features that can enhance one's self-regulation in online gaming, as well as by developing a research model to explain how technological design features influence one's online gaming addiction through the self-regulatory mechanisms. In this research-in-progress paper, we present our research model and hypotheses and describe our research design. We expect that this study contributes to our understanding of the intervention and prevention in the domain of technology addiction.
