differences of this size likely to occur by
chance less often than 1 in 50 such tests).
Thus the only 'significant' effect is an
apparent reduction in the number of mothers
reported as smoking.
Although the other differences are within
chance limits, this does not mean that they
may not be real — only that one cannot be
sure. They are in fact in the direction that
would be expected from a beneficial effect
of the programme.
Falrlop 1. The differences between the treatment groups
here and at Mayfield pre-survey are not
significant.
The difference!! post-survey between the
treatment and control groups nre not significant,
except for Question 1 (fathers smoking),
where x2 (1 d.l.) - 4.321, 0.05 > P> 0.02.
For Question 2 the difference is in the same
direction as lit Mayfield, but is not 'significant'.
General Conclusion
There is a strong suggestion that the
education reduced the number of parents
reported as smoking. The difference in boyrf
smoking habits between treatment and control
groups are consistant with a modest
benefit, but they are not statistically significant."
I cannot add anything more to the succinct general conclusion
which Dr. Rose drew.
I would like to thank Mr. Hicks, Headmaster of Mayfield
and Mr. C. Brantlngham (not present head) Headmaster of
Fairlop for their co-operation.
Also Miss Griffiths, Health Education Officer, for her help
in the preparation of this report.
