Module 3 Flashcards
What are the four issues of concern?
Truth value, applicability, consistency, neutrality
What are the issues of concern directly related to evaluating quantitative research?
Internal validity (to judge truth value), external validity (to judge applicability), reliability (to judge consistency), objectivity (to judge neutrality)
List the issues of concern for evaluating qualitative research.
Credibility (to judge truth value), transferability (to judge applicability), dependability (to judge consistency), confirmability (to judge neutrality)
What are the core principles for ethics in Canadian research?
Justice, concern for welfare, respect for persons
What is emphasised when determining quality of quantitative research?
Replicability
What are the two threats to internal validity that are beyond the researcher’s control?
History, meaning something major occurs that affects one group.
Mortality, meaning a large number of subjects leave one of the groups.
Describe why instrumentation may pose a threat to internal validity of a quantitative study.
Subtle changes in instrumentation between groups can lead to biases, so researcher should make sure all groups/participants are receiving same instrumentation.
What is a key and common threat to the internal validity of a quantitative study?
Bias, which can occur in selection of observations/participants or in info collected.
Why is failing to control for confounders an issue in internal validity?
Internal validity is extent to which researcher can show info collected accurately answers the research question, so only IV caused the change seen in DV. With confounders not being controlled for, researcher can’t prove that only IV caused change in DV as the confounders could be causing the change.
What does the constructive paradigm of qualitative research emphasise when evaluating these types of studies?
Trustworthiness
What can help enhance a qualitative study’s credibility?
Triangulation, member-checking
How is dependability assessed in qualitative studies?
Dependability audit
Considering what assumptions researcher made about study participants/their responses
Researcher’s values, beliefs, or experiences shape questions asked or how they listened
Effect of physical setting of research on participants/how researcher related to them
Contextual issues in need of consideration
What is used to enhance a qualitative study’s confirmability?
Audit trail
Independent reviewer used to determine if interpretations made from observations are supported by data, documentation in the audit trail, relating findings to previous literature
When deciding transferability of a qualitative research study, what should be considered by the reader of the study?
Context of research to determine extent to which the results suggest further study questions/directions for action
What must the researcher provide for transferability to be adequately judged?
Detailed context and methods descriptions
