Question 1

background

Answer 1

in Australia about 1 in 4 children have asthma
^ compliance with asthma medicine at 30-70% for all ages
^ children found spacer devices difficult to use and not fun

Question 2

aim

Answer 2

wanted to see if adding positive reinforcement could be incorporated into an attachment spacer device to help train children in how to use their inhaler properly

Question 3

sample

Answer 3

32 children from Australia (22m:10f)
^ aged 1 1/2 - 6 years old
^ recruited from 7 paediatric or GP clinics within a 51km radius of Perth, western Australia

Question 4

procedure

Answer 4

1. parents were contacted by phone before being visited at home > written informed consent by parents before filling in questionnaires about child’s current inhaler
2. given funhaler for 2 weeks
3. parents were contacted again after the 2 weeks and given another questionnaire (about funhaler)

Question 5

conclusions

Answer 5

parents completely happy
current = 10% funhaler = 61%

unwilling to use
current = 58% funhaler = 3%

desired 4 or more breath cycles
current = 50% funhaler = 80%

Question 6

similarity between Bandura

Answer 6

1. both studied young children
   ^ BANDURA = 72 children : 37- 69 months : equal split of gender : stanford university
2. both sit on the nurture side
   ^ BANDURA = the children imitated non aggressive/ aggressive behaviour after observing models + environment
   ^ CHANEY = their environment was manipulated

Question 7

operant conditioning

Answer 7

behaviour is learned as a result of consequences
^ positively reinforced = disc spinning and whistle after inhaling
^ negatively reinforced = taking away breathless feeling
