Internet use (e.g., smartphone use, social media use) is ubiquitous in our daily lives and plays an increasingly important role in human well-being. Today’s adolescents and their parents spend significant amounts of time on technological devices, such as smartphones, especially during COVID-19. In this year, new research shows that nearly half of American teenagers say they use the Internet “almost constantly”, 95% of American teens have smartphones, and about 54% of teens said it would be “somewhat hard” to give up social media. Hence, further research on the relationship between Internet use and psychological well-being among children and adolescents is worth pursuing. At the same time, a new interest in this area of research is “parental technoference” which was defined as regular interruptions to real-time face-to-face communications, interactions, or time spent together among family members because of parental use of technology. Technoference has become a common phenomenon in many families with children, and evidence has been identified that extended parental time on technological devices (e.g., smartphones) could have negative effects on parent-child relationships and children’s wellbeing. For example, parental phubbing is regarded as a typical parental technoference, and this term is used widely in some countries around the world, which has been demonstrated to be detrimental to their children’s developmental outcomes and cause various psychological health problems.
