Summarise the background to Chaney’s study
- in Australia, 1 in 4 children asthma
- second most common cause of pediatric admissions and major cause of school absences
- non-compliance with inhaled asthma medication is low at 30-70% for all age groups
- children often find recommended breathing techniques difficult
What was Chaney’s aim?
To see if the principles of operant conditioning could be used to train children to breathe through inhalers the right way
What was Chaney’s sample?
32 children (22b, 10g) aged between 1.5 and 6 years old - average had asthma for 2.2 years
How did Chaney obtain his sample?
- recruited on a random basis from several pediatricians or general clinics within a 51km radius of Perth
- clinics spanned widely differing socioeconomic and geographical areas
What was the IV of Chaney’s study?
whether child was using standard AeroChamber, breath - a tech or funhaler
What were the DV’s of Chaney’s study?
questionnaires designed to measure:
- child’s behavior = how frequently took medication and problems child had with delivery
- attitudes of children and parents towards medication
What were the key features of the Funhaler?
a whistle and toy ball that would spin and make noise when took properly.
a mask that would fit easily over the mouth
How was the initial data collected for Chaney’s study?
- parents contacted and complete a questionnaire about current inhaler, including consent form
- no idea about Funhaler
How was the data collected during Chaney’s study?
- parents given Funhaler for 2 weeks to use with child
- parents contacted once by phone randomly and asked if used Funhaler previous day
- children regularly used Funhaler every day (some still used old)
How was the final data collected in Chaney’s study?
- parents visited again and completed a second questionnaire about Funhaler
- interview with same parent as before
What were the results for the percentage of children who had used their inhaler the day before in Chaney’s study?
Ex - 59%
Fun - 81%
What were the results for the percentage of children who achieved 4 or more breath cycles per delivery in Chaney’s study?
Ex - 50%
Fun - 80%
What were the results for the percentage of parents who always successfully medicated their child in Chaney’s study?
Ex - 10%
Fun - 73%
What were the results for the percentage of children unwilling to breathe through device in Chaney’s study?
Ex - 61%
Fun- 73%
What were the results for the percentage of children who screamed when put close to face in Chaney’s study?
Ex - 48%
Fun- 3%
What were the percentages for the 3 attitudes of children towards medication in Chaney’s study?
- Pleasure - Ex = 10%, Fun = 68%
- Acceptance - Ex = 58%, Fun = 19%
- Suspicion - Ex = 0%, Fun = 10%
What were the percentages for the 2 attitudes for the parents towards medication in Chaney’s study?
- Completely happy - Ex = 10%, Fun = 61%
2. Dislike - Ex = 16%, Fun = 0%
What did Chaney conclude about his study?
- The Funhaler led to an increase in medication and an increase in use of Funhaler
- Parents tended to be less likely to give up using inhaler with Funhaler
What ethics did Chaney uphold?
conducted ethically
Why was it good that Chaney used a repeated measures design?
no participants missed using the Funhaler and all got benefit
Did Chaney have internal reliability?
- same questions, length of time
- Funhaler harder to control as in children’s homes
Did Chaney have external reliability?
32 - quite small and inconsistent effects?
Did Chaney have internal validity?
- socially desirable answers?
- compiance measured child’s or parent’s?
Did Chaney have external validity?
- difficult to apply to other cultures and age ranges
