Chaney Et Al Flashcards
Background of chaney et al (2004) study into fun haler
Asthma is potentially a dangerous condition treated using medication via an inhaler.
Aim
To conduct a pilot study to see whether a fun haler Would increase medical compliance in young children with asthma.
Design method of chaney et al (2004) study into fun haler
Field experiment repeated message design, using self report to collect data
IV- child using conventional asthma, spacer device or funhaler
DV- data on use of spacer and on attitudes collected from parents
Sample of chaney et al (2004) study into fun haler
Opportunity sample, 32 children attending clinics within 51 KM radius in Australia and their parents children age between 1.5 and six years mean age 3.2 years average duration of asthma was 2.2 years there was 22 boys and 10 girls
Material/apparatus of chaney et al (2004) study into fun haler
New spaces design for children, the funhaler looks like a brightly coloured toy with a spinning desk and whistle activated by child’s breathing patterns
Too much questionnaires of mainly yes/no questions and fix choice questions given before, and after children use the fun Haler, the question as measured attitudes to the use of an inhaler and compliance to the medication .
Procedure
Parents of children with asthma, contacted and study Explained to them.
Informed consent obtained by parents before being interviewed
One parent interviewed using questionnaire one
The one parent was asked about their attitude, and their child’s attitude to the existing conventional spacer
Children were given a funhaler to use under adult supervision for two weeks in place of their current device
Funhaler. Assessed by parents once at random during the study. Asked about use on previous day.
Parents were visited by the research at the end of the two weeks and questionnaire 2 was given to the parent who responded on the first occasion.
The one parent was asked about their attitude and their child’s attitude to the fun Haler
Results?
Adherence 81% of children use the funhaler compared to 59% using C S
Children’s positive attitudes, for example, 68% experience pleasure with the fun Haler compared to 10% with the C S
Positive attitudes, for example 61%, but completely happy with the fun halo compared to the 10% completely happy with a CS
Research method and techniques
+ repeated message to sign controls for the effect of participant variables e.g. some children may have more severe asthma or be naturally more compliant. This increases the validity of results.
-Social desirability bias may be shown by parents and self-report, as they may have provided more positive views about the fun Haler because they knew the aims of the study
Validity
-Trials were short-term lasting only two weeks. The positive attitudes expressed by parents may be related to the novelty of the device over a longer period e.g. six months use of the fun Haler by parents and children may have less positive attitudes.
Reliability
The question is may like reliability, e.g. parents may have interpreted terms such as mild or strong differently, when assessing their child’s dislike inhaler
Sampling bias
-The opportunity sample was easy to obtain, but not representative of the general population. The sample came from area of 51 KM radius that may have unique characteristics, e.g. more willing to try a new device.
Type of data
+ quantitative data, parents were asked either, yes/no questions, questions, or questions with a fixed range of answers
-Force choice questions, such as always use spacer versus do not always use. Spacer means that finer detail was lost.
Ethical considerations
inform consent was obtained from parents, but children might later object to having been used in a trial of the new medical device
Psychological harmony causes children may feel embarrassed about using a spacer device
