23
Q

What is an advantage and disadvantage of longitudinal studies?

A

Advantage: Participants share the same history at different points of time, same people NOW as they were THEN.
Disadvantage: Time-consuming and expensive, may lose participants (called attrition –> sampling bias)

A

now and later

Always retrospective
26
Explain cross-sectional studies...
Data collected once for two different groups, compares now and later (e.g. employees vs new graduates, see the difference 'experience' makes)
27
What are the advantages and disadvantages of cross-sectional studies?
Advantage: quicker, cheaper, usually easier, less risk of attrition and associated bias (than longitudinal) Disadvantage: Two groups may not share the same history, may have group differences that relate to time, background factors etc
28
Which are preferred scientifically, longitudinal studies or cross-sectional studies?
Longitudinal, but can be impractical
29
The aim of epidemiological research is to see...
Whether (or by how much) exposure to a hazard increases the later risk of a disease or change in health.
30
What are the two main study designs for epidemiological research?
- Cohort study | - Case-control study
31
What is a cohort study?
Relates to exposure to risk, looks at whether exposure relates to subsequent health outcomes.
32
The cohort studies starts by identifying two | groups according to their exposure to a hazard or a protective event...?
1. Exposed to treatment or hazard. | 2. Not exposed to treatment or hazard.
33
Case-control studies relates outcomes to ...?
earlier exposure
34
Case-control studies vs. cohort studies....?
- Studies relating exposure to risk – the cohort study. | - Studies relating risk to exposure – the case-control study
35
Explain action research
Different type of research to all others, specifically about change in the workplace (always about workers), changes in the way things are done the then effect of changes
36
Explain systematic reviews...
They are studies of studies that combine data for an overall conclusion

38
Why is prospective research considered scientifically superior to retrospective research?
More knowledge about horses is needed to pick the winner before a horse-race is run than picking the winner after the race
