Exploratory Research Flashcards
Exploratory Research data collection methods
Longituinal or Cross-sectional:
according to how many times you measure outcomes
Prospective or Retrospective:
according to timing of event for data to be collected
Types of exploratory research
Cohort study
Case Control Study
Prospective research design
variables measured through direct recording in present
researcher follows subjects as they progress
Retrospective
data collected in the past
often obtained from medical records, databases, or surveys
Longitudinal or Cross Sectional:
researcher follow cohort over time
Longitudinal
Longitudinal or Cross Sectional:
data collected in time sequence with repeated measurements at prescribed intervals
Longitudinal
Longitudinal or Cross Sectional:
researcher studies stratified group of subjects at one point in time
Cross sectional
Longitudinal or Cross Sectional:
researcher may compare characteristics of those strata to draw conclusions
Cross Sectional
Longitudinal or Cross Sectional:
researcher may describe patterns of change
longitudinal
T/F:
cross sectional is cheap and easy way to gather initial data and ID correlations that can further be used in longitudinal study
True
Cohort Study
group of individuals followed together over time
follows subjects without outcome of interest to see if they develop the disorder
Cohort Study
ID risk of exposures by:
comparing incidence of specific outcomes in those who were and were not exposed
Case Control Study
researcher looks back in time to determine if groups differ with respect to their exposure histories
Case Control Study:
Cases
those classified as having the disorder
Case Control Study:
Controls
those chosen as a comparison group without disorder
