Week 5 Flashcards
What is the relevance of experiments and quasi-experiments in nursing research?
Control, causal mechanism, internal validity, random assignment
Lacks the manipulation of an independent variable, random assignment or participants to conditions or orders of conditions, or both
Non-experimental research
What are the types of non-experimental research?
survey, secondary data analysis
Give an example of secondary data analysis.
Using the dataset generated by Statistics Canada and then analyzing it
Using someone else’s data and performing an analysis on it
secondary data analysis
A method of investigation that uses question-based methods to collection information about how people think and act
survey research
What is the purpose of survey study?
Correlational study - relationships among variables
Developmental study - changes over time
How are survey studies classified by duration of study?
Cross-sectional - present - retrospective Longitudinal - Prospective
Name the survey study type based on the description.
A - Collect information at one point in time
B - Ask people to provide information regarding something that happened in the past
C - Evaluate variables along multiple waves
D - Collecting data at this time
A - Cross-sectional
B - Retrospective
C - Longitudinal
D - Present
Compare Prospective and retrospective on the following parameters:
- Cost
- Time spent/duration
- Degree of control
- Selection bias/recall bias
Cost - prospective costs more
Duration - prospective has more time spent
Degree of control - both studies may have many extraneous variables which may confound the data
Selection bias/recall bias - both are threats to validity
What are the advantages of survey research?
Allow us to develop multiple research questions
External validity tends to be strong
Large sample sizes
What are the disadvantages of survey research?
Providing weaker tests of causality
What are the advantages of open-ended questions?
Diversity/richer information source
Autonomy
Qualitative
What are the disadvantages of open-ended questions?
Going off topic
gather unnecessary information
Coding/Analysis (difficult)
Bias in interpretation/misinterpretation
What are the advantages of closed-ended questions?
Precise
easier to analyze/code
easier to answer
Cheaper to administer
What are the disadvantages of closed-ended questions?
Unclear
not exhaustive/mutually exclusive or answer unsuitable
Some researchers suggest what in regards to the use of closed and open-ended questions?
Use open ended-questions as a pilot test to develop closed ended questions
Questions that ask participants to choose a number representing the direction and strength of their response
Rating Qs
What are two types of rating Qs?
Likert scale
Semantic differential
Questions that ask a person to rate a product, brand or service based on a rating scale that has two bi-polar adjectives at each end
Semantic differential
