What level of digital exposure is 'just right'?

A study of 6000 teenagers has suggested that the ‘Goldilocks’ hypothesis for digital exposure applies to young people.

The research from the Department of Sociology in Trinity College Dublin found further evidence of a relationship between online engagement and mental wellbeing in teenagers.

Published recently in the journal Computers in Human Behaviour, this new study contributes to mounting international evidence on the dangers of high levels of digital media use.

Additionally, the researchers found that in today’s connected world, low engagement with digital media is also associated with poor mental health outcomes for adolescents who spend less time online than their peers. This finding supports the ‘Goldilocks’ hypothesis — that digital media use at moderate levels is not intrinsically harmful and there is a point between low and high use that is ‘just right’ for young people.

This is the first time the Goldilocks theory has been examined in Irish teenagers/young adults. It is also the first study to attempt the integration of both time and online behaviours when examining associations between digital media and mental wellbeing.

“Evidence is mounting internationally that online engagement among adolescents may be damaging for mental wellbeing, but the evidence is mixed. Our work provides fresh insights on the impact of digital engagement at the age of 17–18 and the results provide worrying evidence of real harms that require urgent action,” said Professor Richard Layte, Professor of Sociology and co-author on the paper.

“There is a simple narrative out there that more is worse. It is important to emphasise that online engagement is now a normal channel of social participation and non-use has consequences. Our findings also raise the possibility that moderate use is important in today’s digital world and that low levels of online engagement carries its own risks. Now the questions for researchers are how much is too much and how little is too little?”

The research, drawing on longitudinal data from the Growing Up in Ireland study, looked at the association between adolescent use of online engagement and mental wellbeing in over 6000 young people between the ages of nine and 13, and again at the age of 17–18.

The researchers asked participants to report the time they spent online as well as the activities they engaged in: online messaging, sharing of videos and pictures, school or college work, watching movies and listening to music. Mental wellbeing was assessed by questions investigating emotional, behavioural and peer issues.

The study characterised young persons’ online behaviour based on length of time spent online as well as the types of online behaviours engaged in. Adjusting for prior psychiatric disorders and symptoms at the age of nine and 13, the study found that high engagement in digital media strongly predicted worse mental health outcomes for both boys and girls. Furthermore, low use of digital media was associated with worse mental health for both boys and girls and was also predictive of peer problems for girls.

Dr Ross Brannigan, lead author of the study and a former postdoctoral researcher in Trinity’s Department of Sociology, said:

“This study is novel in that it considers the importance of both time and online behaviours when examining associations between digital media and mental wellbeing. We found clear distinctions between groups spending similar time online, but differing in their behaviours online. This indicates the importance of considering both time and behaviours online as well as the quality of these behaviours; for example, passive compared to active behaviours, or the types of behaviours such as social, educational, entertainment.

“Digital media and online usage is a controversial topic when it comes to its effect on mental health, with no real consistency of results overall. While these results are not causal or deterministic, our findings are an important first step on the path to revealing why these relationships exist. It will now be important to build on these findings and further investigate why digital media engagement may be related to mental wellbeing.”
