Definitions- Module 2 Flashcards
The branch of philosophy connected with nature and the definition of knowledge and truth, while also defining the types of data considered as ‘valid’ and useful
Epistemology
Examines valid knowledge and generates truth through scientific processes based on observation/measurement and generalization
Positivism
Produces meaning and determines social phenomena, through complex/contradictory perceptions
Interpretivism
The branch of philosophy connected with the nature of reality
Ontology
Views the existence of phenomena as external objects independently of observation and human perception
Objectivism
Views phenomena as a socially constructed object that is developed through human interpretation
Constructionism
Relies on numeric data and statistical analysis
Quantitative Research
Relies on open-ended questions concerned with meaning and experience
Qualitative Research
Reflects one’s belief about what constitutes knowledge and how that knowledge is to be generated
Research Paradigms
Are driven by study questions, available populations for study, resources, and current states of research
Study Designs
Used to evaluate the therapeutic effects of treatments in diseased individuals or the beneficial effects of a protective agent or screening procedure
Randomized Controlled Trial
A group that is controlled by the researcher, who determines which receives the treatment and which receives the alternative
Experimental Group
When participants receive intervention or become controls and are followed over time
Prospective
The group in the experiment that receives the alternative
Control Group
The sham procedure that has no specific therapeutic effect but is intended to make the recipient think they might be receiving treatment
Placebo
When participants are randomly assigned to intervention or control (mitigates selection bias)
Random
When individuals without the disease of interest are sampled and classified according to whether they have had the exposure of interest or not
Cohort Study
Attempts to select participants that reflect the general population of interest
Population-Based Sample
Attempts to ensure adequate numbers of exposed individuals when exposure is rare
Exposure-Based Sample
When other factors can affect the outcome of the results
Confounding Variables
Studies cases from a specified population
Case Study
When there is no measured follow-up time, and past exposures are examined
Retrospective
When populations are sampled and exposure/disease statuses are measured at the same time
Cross-Sectional/Prevalence Study
When data that summarizes exposure/disease is sampled from populations
Ecological
