Chaney et al - Developmental area Flashcards
What are behaviour therapy and behaviour modification based on?
- Based on classical conditioning
- Based on operant conditioning
What doesn’t necessarily improve with rising severity of illness?
Adherence
What did Watt et al propose would improve medical adherence in young asthmatics?
That a positive interplay of adherence considerations with aerosol output factors would improve medication adherence in young asthmatics
What is operant conditioning?
- It is a form of associative learning
- Whereby, associations and connections are formed between stimuli and responses that didn’t exist before learning occurs
What does operant conditioning involve?
It involves learning through the consequences of behavioural responses
Who first investigated the principles of operant conditioning?
Thorndike
What did he find?
- Found that any response that led to desirable consequences was more likely to be repeated
- Any response that led to undersirable consequences was less likely to be repeated - a principle which became known as the Law of Effect
What was the aim of this study?
- The aim of this study was to show that the use of a novel asthma spacer device, the ‘Funhaler’, which incorporated incentive toys isolated from the main inspiratory circuit by a valve whilst not compromising drug delivery
- can provide positive reinforcement which leads to improved adherence in young asthmatics
What experimental method was used?
Field experiment
What was the experimental design that was used?
Repeated measures design
What was the IV? (2)
- Whether the child used a standard/small volume spacer device - The breath-A-Tech
- Whether the child used a Funhaler
What was the DV?
The amount of adherence to the prescribed medical regime
How many children were in the study? (gender)
- 32 children
- 22 male, 10 female
Where was the study conducted?
Conducted in the P’s home setting in Australia
On average, how long had the children had asthma?
2.2 years
How did the children’s parents get involved?
- Helped (where necessary) in the use of the inhalers
- Completed questionnaires and took part in a phone interview
What did the parents provide?
Provided informed consent
What was the sampling technique?
Random sampling
How were P’s recruited?
Recruited from clinics across a large area
What happened first? (inhalers)
- Firstly, a comparison was made between the aerosol output of the standard/small volume spacer device
- 235ml Breath-A-Tech
- 225ml Funhaler
Was there any differences observed?
There was no significant differences observed
What did that mean for the comparison?
- The comparison was therefore complementary
- It indicated that the use of a Funhaler rather than a standard inhaler does not compromise drug delivery
How were participants approached by the researcher?
- Approached by the researcher at home
- Before the Funhaler was even mentioned
- They were interviewed with a questionnaire on their existing use of the inhaler
How long were they given the funhaler?
Two weeks
