Do one in four girls aged 14 really suffer from depression? Probably not

Toby Young writing for The Spectator asks:  Are British teenagers suffering from an epidemic of mental illness? Yes, according to a ‘government-funded study’ which found that 24 per cent of 14-year-old girls are suffering from depression.

This has been seized upon by critics of Conservative education policies; they see it as ‘proof’ that the increased focus on teaching children knowledge, as well as more frequent testing and the GCSE reforms, have literally driven children mad. ‘One in four girls is clinically depressed by the time they turn 14,’ reported the Guardian

I’m sceptical about this and I took a look at the research carried out by the Centre for Longitudinal Studies, which is based at UCL Institute for Education. It involved asking 14-year-olds in the Millennium Cohort Study to fill out a questionnaire called Short Moods and Feelings. This is an American document that uses the Diagnostic and Statistical Manual of Mental Disorders’ criteria for depression. It lists 13 symptoms in the form of first-person statements like ‘I thought I could never be as good as other kids’ and asks respondents to indicate ‘Not true’, ‘Sometimes’ or ‘True’, depending on how often they’ve experienced these feeling in the past two weeks. A total of 11,394 children completed the survey, which is a respectable sample size.

A more fundamental problem is that the questionnaire is not designed as a diagnostic tool. Indeed, if you look it up you’ll see the following explicit warning: ‘This instrument should be used as an indicator of depressive symptoms and not as a diagnostic tool and therefore does not indicate whether a child or adolescent has a particular disorder.’

It may be that the researchers used the phrase ‘high symptoms of depression’ to avoid falling into this error, and not because they were trying to exaggerate the scale of the problem, but no such circumspection was shown by newspapers reporting it. The Guardian was far from alone in this respect. Here’s a sample of the headlines: ‘A quarter of all 14-year-old girls are depressed’ (The Independent), ‘One in four teenage girls are depressed’ (Daily Telegraph), ‘One in four 14-year-old girls is depressed’ (The TES). In fact, the research tells us nothing of the kind.

So treat this survey and the inflated claims being made on the back of it with a large dose of salt. It doesn’t tell us much about how prevalent depression is among teenagers, and it doesn’t tell us anything about whether it’s rising or falling.

  1. ‘Being depressed’ is the ‘in’ thing……and it gives teenagers the perfect excuse to absolve themselves from any personal responsibility.

    In a way, though, it’s hardly surprising if teens are a bit fed up. They spend their primary years being told to believe in themselves, that they are ‘fantastic’, ‘amazing’ etc and then start to grow up and realise that they are not so amazing after all.
