Apr 17, 2018
Cannot prove causation; results may not be generalizable.
- Clinical research often takes the form of case studies to research clinical disorders.
- A case study is an observation technique in which one person is studied in depth in the hope of revealing universal principles. The issues with case studies are that:
- They cannot lead to conclusions regarding causality.
- The individual studied may be atypical of the larger population.
- Researchers try to ensure that their studies are generalizable; that is, applicable to similar circumstances because of the predictable outcomes of repeated tests.
