Smartphone use is an addiction for a quarter of youngsters – study shows

The study, by researchers at King’s College London and published in BMC Psychiatry, analysed 41 studies published since 2011 on smartphone usage and mental health involving more than 40,000 under-20s.

It showed that on average 23% of youngsters were showing signs of “problematic smartphone usage” (PSU).

The researchers defined PSU as behaviour linked to smartphone use that has an element of addiction – such as anxiety when the phone is unavailable or causing neglect of other activities.

The study also found that there are links between PSU and mental health issues such as anxiety, stress, poor sleep and depressed moods.

Co-senior author Dr Nicola Kalk from the Institute of Psychiatry, Psychology and Neuroscience, said: “Smartphones are here to stay and there is a need to understand the prevalence of problematic smartphone usage.

“We don’t know whether it is the smartphone itself that can be addictive or the apps that people use.

“Nevertheless, there is a need for public awareness around smartphone use in children and young people, and parents should be aware of how much time their children spend on their phones.”

The study authors note that 22 of the studies examined were of “poor methodological quality” and that there was wide variation across the research analysed in the definitions of PSU.

Dr Sam Chamberlain, Wellcome Trust Clinical Fellow, Honorary Consultant Psychiatrist, University of Cambridge, said: “Research into PSU is important from a public health point of view. The authors report that approximately 10-30% of young people in the studies included in their meta-analysis met a chosen threshold for having PSU.

“Also, PSU was associated with (by self-report measures) higher levels of depression, anxiety, and worse sleep. These results resonate with previous findings, including those on related topics such as Problematic Usage of the Internet.”

He added: “One challenge for the field, in light of this valuable meta-analysis, is that Problematic Smartphone Use is not consistently defined.

“There are various rating scales, with different cut-offs and criteria, some of which have not been subjected to sufficient clinical (and other) validation.”
