There is broad agreement that internet access is important for children and provides them with many opportunities. Yet crucial questions remain about what we hope children will do online and if the opportunities provided are translating into clear benefits. What do children actually need to be able to benefit from the opportunities that the internet brings? Is there a gap between expectations and reality? The answers to these questions matter to: Governments striving to provide connectivity for families in homes, schools and communities; parents and educators who must overcome problems of cost, risk, or lack of skill, so that children may benefit from online opportunities; child rights advocates and practitioners who call for resources to empower and protect children online; and children themselves, many of whom want to take advantage of online opportunities for personal benefit.

Based on an evidence-focused literature review, the first part of this paper examines existing knowledge on how the time children spend using digital technology impacts their well-being across three dimensions; mental/psychological, social and physical. The evidence reviewed here is largely inconclusive with respect to impact on children’s physical activity, but indicates that digital technology seems to be beneficial for children’s social relationships. In terms of impact on children’s mental well-being, the most robust studies suggest that the relationship is U-shaped, where no use and excessive use can have a small negative impact on mental well-being, while moderate use can have a small positive impact. In the second part of the paper, the hypothetical idea of addiction to technology is introduced and scrutinized. This is followed by an overview of the hypothetical idea that digital technology might re-wire or hijack children’s brains; an assumption that is challenged by recent neuroscience evidence. In conclusion, considerable methodological limitations exist across the spectrum of research on the impact of digital technology on child well-being, including the majority of the studies on time use reviewed here, and those studies concerned with clinical or brain impacts. This prompts reconsideration of how research in this area is conducted. Finally, recommendations for strengthening research practices are offered.

The international community has recognized the importance of internet access for development, economic growth and the realization of civil rights and is actively seeking ways to ensure universal internet access to all segments of society. Children should be an important part of this process, not only because they represent a substantial percentage of internet users but also because they play an important part in shaping the internet.
