This study looks at how common internet addiction is among adults in Hong Kong and how it affects their mental health and well-being. Internet addiction (IA) means spending too much time online, which can lead to problems like anxiety, depression, and poor sleep. The study will use questionnaires to ask about internet use, feelings of depression and anxiety, sleep quality, quality of life (QOL), and basic demographic information, especially during COVID-19 and the rise of the Metaverse.
