Digital well-being has emerged as a significant area of research amid the rapid advancement of artificial intelligence (AI) and digital mental health technologies. To capture the intellectual development of this field, a bibliometric analysis was conducted using publications indexed in the Scopus database between 2020 and 2025. Following the identification, screening, and selection processes based on predefined criteria, a total of 422 articles were included in the analysis. Bibliometric mapping was performed using VOSviewer through publication trend analysis, citation analysis, co-authorship analysis, and keyword co-occurrence analysis to identify publication trends, author productivity, country contributions, subject areas, and emerging research themes. The results reveal a substantial increase in digital well-being publications during the study period, reflecting its emergence as a multidisciplinary research field. The most prominent themes include digital well-being, social media, mental health, psychological well-being, and digital literacy. Network visualization indicates strong interconnections among digital well-being, mental health, social media use, and digital behavior. Furthermore, topics such as smartphone addiction, screen time, internet addiction, emotional regulation, and artificial intelligence have emerged as rapidly growing research themes in recent years. The United States and the United Kingdom were identified as the leading contributors to the literature, while Social Sciences, Medicine, Computer Science, and Psychology constituted the dominant disciplinary areas. These findings highlight that digital well-being has evolved into a multidisciplinary framework integrating psychological, social, health, and technological dimensions, while providing valuable directions for future research and the development of digital mental health practices.
