OBJECTIVE
To determine
whether rewording postal reminder cards according to the "health
belief model", a theory about preventive health behaviour, would help
to improve measles vaccination rates.
DESIGN
A randomised
controlled trial, with blind assessment of outcome status. Parents of
children due for their first measles vaccination were randomised to one
of two groups, one receiving the health belief model reminder card, the
other receiving the usual, neutrally worded card. The proportion of
children subsequently vaccinated in each group over a five week period
was ascertained from clinical (provider based) records.
SETTING
A local
government operated public vaccination clinic.
PARTICIPANTS
Parents
of 259 children due for measles vaccination.
MAIN RESULTS
The
proportion of children vaccinated in the health belief model card group
was 79% compared with 67% of those sent the usual card (95% CI, 2%
to 23%), a modest but important improvement.
CONCLUSION
This study
illustrates how the effectiveness of a minimal and widely practised
intervention to promote vaccination compliance can be improved with
negligible additional effort.
