University students experience major transition difficulties when they move from school to university because their digital dependency keeps growing. The research indicates that college adjustment consists of three interconnected elements, which include academic performance management, university social life adaptation, institutional commitment, and personal well-being (Baker & Siryk, 1999; Ribbe, Cyrus, & Langan, 2016). The research field lacks sufficient studies about how college students adapt to university life when their internet and gaming addiction levels rise. Our research investigates how excessive internet and gaming use affects university students during their transition to college life. We obtained survey responses from N≥250 sophomores of a large residential university through stratified sampling. We used the Inventory of New College Student Adjustment (INCA), Young's Internet Addiction Test (IAT), and the Internet Gaming Disorder Scale-Short Form (IGDS9-SF) to obtain the dataset. We used the structural equation modeling (SEM) approach to analyze our research model. We strongly believe that students who spend more time on the internet and gaming systems face greater challenges in their college adaptation process. Our research found that students need help managing their technology use because it affects their ability to build strong relationships and develop confidence in their academic performance during college. We then provide theoretical and practical implications of our research.
