Preventing dog bites in children: a randomised controlled trial of an educational intervention
Objectives To evaluate the impact of a school educational program on dissuading children from inappropriately approaching or patting strange dogs
Design Randomised controlled trial
Participants 346 Sydney children aged 7-8
Intervention The single lesson Prevent-a-Bite program
Main outcome measures Prescribed precautionary behaviour with a strange dog, measured 7-10 days after the intervention.
Results 80% of children in the control schools not receiving the intervention behaved inappropriately near a strange dog tethered in the playground compared to 9% of children in the intervention group (χ2212.30, Df=1, P<0.0001).
Conclusions The Prevent-a-Bite intervention dramatically increases precautionary behaviour of young children around strange dogs in the short term. Further research is needed to evaluate longer term outcomes.
(null) that there will be no difference in the rates at which primary school children approach and pat a strange dog between children exposed to the Prevent-a-Bite education lesson and those not exposed to the lesson.
Study population: Sydney, Australia primary school children aged 7-8
Intervention: the single lesson Prevent-a-Bite educational intervention
Outcome measure: approaching and patting a strange, tethered dog in a school playground
Statistical analysis: chi squared difference between intervention and control groups Assignment
Unit of randomization: Randomised cluster assignment of 8 primary schools to four intervention and four control groups.
Allocation concealment: intervention group children participated in Prevent-a-bite lesson; control schools did not. All children were unaware that their behaviour around the dog was being videoed.
Masking: One of three video coders was blind to intervention/control status of children shown on video tape when outcome was being assessed. All coders were required to agree to a child's behaviour constituting a pat before it was recorded as such.
8 Sydney primary schools randomly selected Randomised Intervention group: Control group: n=4 schools, 197 children n=4 schools, 149 children Received intervention Did not receive intervention
Analysis: 80% (119/149) of children in the control schools not receiving the intervention behaved inappropriately near a strange dog tethered in the playground compared to 9% (18/197) of children in the intervention group (χ2=212.30, Df=1, P<0.0001).
Comment: In this trial the Prevent-a-Bite intervention dramatically increased precautionary behaviour of young children around strange dogs in the short term. Further research is needed to evaluate longer term outcomes.
