week 3 research paradigms Flashcards
two aspects of conceptualization of health
- personal trouble - lived experience
- public issue - understand social determinants that shape health
what is a paradigm?
refers to the assumptive base underlying a
particular investigation or enquiry that has been undertaken * i.e., Philosophical basis of a research project
reflects beliefs about what constitutes knowledge and how that knowledge is generated.
what is epistemology?
the branch of philosophy concerned with the nature and definition of knowledge and truth
what are the 3 types of epistemology?
- Positivism
- Interpretivism
- Critical realism
what is ontology
the branch of philosophy concerned with the nature of reality.
what are the two types of ontology
Objectivism
* Constructionism
what is methodology
approach to data collection and analysis
what are the two types of methodology?
qualitative
quantitative
what is positivism?
branch of epistemology
- views scientific data as neutral and unbiased
Emphasizes:
* rigorous measurement of variables
* testing of hypotheses
* analysis of cause-effect relationships
* the generation of laws and principles
what are the main methods of positivist research
Epidemiological study designs, such as
* randomized controlled trials
* cohort studies
* cross sectional studies
* Survey research
* Secondary document analysis, such as
* content analysis
* Structured interviewing
* Systematic reviews, such as * meta-analysis
features of positivist research
- determinism - Phenomena can be predicted from a knowledge of scientific
laws - objectivity
- quantification
- reliability
- generalizability
pros of positivism
Positivist designs use consistent and relatively
concrete outcome measures
*
Techniques of randomization and blinding are
effective means of reducing bias
cons of positivism
Many questions about health cannot be addressed with a positivist approach
* For example, questions surrounding “why”
Some have argued that positivist quantitative research designs give insufficient attention to a person’s lived experience
Difficulties remain in dissecting and categorizing life circumstances
what is interpretivism?
the purpose of research is to understand how people make sense of their situation/circumstance.
* Valid knowledge and truth is subjective in
nature!
* Focuses on the interpretations of respondents
rather than on seeking to measure or categorize behaviour or attitudes
features of interpretism
- objectivity and scientific process is not neutral
-less formal methods - not concerned with interference or social relations
- research is not always replicable
High on validity, not necessarily on reliability
