Week 2 Flashcards
How is data collected for qualitative research?
Interviews
Observation/field notes
Reading documents for background
How is data analyzed for qualitative research?
Code all of data and then try to find themes between them
Mixed methods
When qualitative and quantitative data are both used in one research
What does descriptive/observational research describe?
Samples through observation
Methodological research
Studies examining reliability and validity
What has highest validity between prospective, retrospective, and cross sectional?
Prospective
Natural history
Looking at a disease as it progresses over time
Normative studies
Normal/functional ROM or strength
Surveys and case studies
Descriptive/observational
N of 1 study
Following one patient and is prospective (experimental)
Case study
Observational
Retrospective
Less internal validity
When are case studies valuable?
They show a lot of detail as well as the thought process of clinical reasoning
What are the benefits of a N of 1 study?
Greater internal validity and more patient focused
Exploratory research
Investigating relationships between 2 or more variables
What is correlation a precursor to?
Prediction
Cohort study
Prospective
Rare exposures
Multiple outcomes
Slow
Expensive
Strong evidence
Case control studies
Retrospective
Rare outcomes
Multiple exposures
Fast
Inexpensive
Weak evidence
Quasi experimental research design
Lacks random assignment
Experimental research
Has a comparison or control group, randomly assigns participants to groups
What are the 5 criteria to define cause and effect relationship?
Time sequence
Strength of association
Biologic credibility
Consistency with other studies
Dose response relationships
Time series design
3x pre test
Intervention
3x post test
Why is a time series strong than a quasi experimental?
More testing (accounting for history)
Narrative review
Selective review of literature
Authors can cherry pick articles
Broadly covers topic
Prone to bias
