Teens aren’t addicted to their phones – but we like to think they are - New Scientist News

Know any teenagers? Chances are they’ll have a phone on them – and that’s a big mental health problem. At least, that’s the impression you get from some of the headlines today, saying one in four teenagers are addicted to their smartphone.

We’ve seen headlines like this before. This time they’re based on a paper that found 23 per cent of teens are using their phones in a problematic way. An accompanying press release said that this was “consistent with a behavioural addiction”.

The paper also found that those with problematic use were three times more likely to be depressed, anxious, and to be not getting enough sleep. The narrative is irresistible: smartphones are giving our children mental health problems.

But perhaps we should stop and think before we get too alarmed. It’s highly debatable whether anyone can be addicted to their phone – or to using the internet or playing computer games. Some researchers in the area say they can, while others say it’s meaningless to use the term addiction in this context.

The new paper, which is a summary of 41 previous studies of phone use, doesn’t shed light on this almost philosophical question, except to confirm that some teens are on their phones an awful lot. I think their families knew that anyway.

The researchers looked at studies that used surveys to assess people’s behaviour. The most common survey includes several questions that could merely indicate high levels of phone use without it necessarily being a pathological medical condition.

Questions include whether people use their phone for longer than they had intended, whether it had caused them to miss some planned schoolwork, or if they had been told by others they were using it too much.

But can this really identify addiction? Substitute “phone” for “book” and you can imagine a keen reader answering yes to many of these questions, but we don’t tend to despair about reading addicts.

When I put this to one of the study authors, Nicola Kalk of King’s College London, she said the surveys were widely used. She also cited examples of teenagers who spend so much time gaming on their phones that they won’t even stop to get washed or leave the house.

That certainly would be disturbing behaviour, but this study does not tell us anything about the number of teenagers in such an extreme state.

Another concern is that the studies included in the review were unrepresentative, says Amy Orben at the University of Cambridge. That’s because Kalk’s team scanned the database of all studies on phone use using “addictive” as one of the search terms. Studies that found low levels of problematic use may have been overlooked, says Orben.

Kalk and her co-author Ben Carter agree this is a limitation but say the findings still suggest a pattern that requires further investigation.

The other claim, that phones are making young people depressed, is not supported at all; the studies merely show a correlation between phone use and mental health problems, not that phones are the cause.

It’s quite plausible that being depressed because you don’t have many school friends makes you more likely to game or talk to people online as way of coping. If that’s the case, any parents who respond to the latest headlines by taking their child’s phone away might be making things worse.

To be fair to Kalk’s team, they do state in their paper they have only found an “association” between phone use and mental health problems, but the fact that that this is no proof of causation has been glossed over in much of the media coverage. It’s almost as if journalists can’t resist a good story about teenagers and their phones. You might say we’re addicted.
