A Cochrane Review : highest level of evidence……
11 randomised contol trials (RCTs)
“There was... no evidence that debriefing reduced general psychological morbidity, depression or
anxiety.”
“Compulsory debriefing of victims of trauma should cease”
“Least said, soonest mended” ????

What did the inspection report say about the worst school on racism?
“Relationships in the school are very good.”
If ‘driving up standards’or ‘pushing kids’ worked….
then standards would have risen

McCord J. A thirty year follow-up of treatment effects. American Psychologist 1978;33:284-9.
McCordCounselling and support were given over a period of five years to families of ‘at risk’ young males in their teens
Thirty years later they remembered their social workers with affection andreported that the help had led themaway from crime…..
When objective measures were usedbased on records such as
the number of arreststhe seriousness of crimesand recidivism….
…some results showed NO differences( between those helped or not helped)
We may do harm when we intend to do good.
and some showed differences in favour of those who hadNOT been provided with help.

‘Some mentoring programmes had a negative
impact’
Some mentoring programmes were worse than useless:
they did harm and wasted peoples’ time and money
THE POLITE SUMMARY:
THE BLUNT SUMMARY:
The moral is……..
We must stop guessing and start experimenting
FINDING OUT WHAT WORKS WITH:
Randomised Control Trials
Demographic….E.g. gender
Ethnicity social class
DD For the school….
these are un-alterable variables
- - - WHY so popular with academics?
EFFECT SIZE = ~0.40 for PROOF READING

GENDER DIFFERENCES - - - very popular with academics
BUT
Scared straightconclusion of Cochrane
summary
Programmes like ‘Scared Straight’
are likely to have a harmful effect
and increase delinquency relative to
doing nothing at all to the same
youths.

It is one of the most characteristic aspects of the
present situation that specific reforms are advocated as

reforms-as-experiments.org.uk a new charity
Committed to professional development of evidence-based educational practice
in order to make a better world - - -a civil, safe and fair society - - - .
WHY EDUCATION?15,000 hours of compulsory treatment should be a great
opportunity....IFF we get the evidence right....
WHY EXPERIMENTS?Because guessing isn't good enough
.... good intentions are no guarantee of good outcomes
