  • conceptual
  • design and planning
  • empirical
  • analytic
  • dissemination
17
Q

What is involved in the conceptual phase of a quantitative study?

A
  • identifying a problem
  • determine variables
  • determine clinical relevance
  • determine Methodology issues
  • determine ethical issues
  • lit review is done to provide background knowledge
  • hypothesis is formed
18
Q

What is involved in the design and planning phase of a quantitative study?

A
  • how often is data collected
  • how to reduce bias
  • how to structure the control
  • intervention protocol : specify intervention and the alternate to be used for comparison
  • define the population –> should allow the results to be generalized
  • methods to measure the variables and collection protocol
  • how to ensure ethical principles are followed
  • study is assess or critiqued
19
Q

What is involved in the empirical phase of a quantitative study?

A
  • collecting data according to the pre planned method

- coded to numerical values if necessary

20
Q

What is involved in the analytic phase of a quantitative study?

A
  • formal statistical analysis of the data collected
  • results of data analysis are interpreted
  • clinical significance / conclusions are discussed
21
Q

What is involved in the dissemination phase of a quantitative study?

A
  • preparing the research report

- using the evidence in practice

22
Q

What are the 3 theoretical backgrounds for qualitative studies?

A
  • grounded theory
  • phenomenology
  • ethnography
23
Q

What is grounded theory in relation to a qualitative study?

A

ethnography

29
Q

What are the steps in a qualitative research study?

How does the process differ from a quantitative study?

A
  • determine a problem : can be broad and become more specific once the study has began
  • literature review : usually small - sometimes omitted b/c thought it might influence findings
  • research sites : since require human perspectives the env is important –> may need permission to be there
  • overall approach : data collection can impact the design and can be done for a design is finalized
  • ethics : need to be addressed bc the participant is developing a rapport with the researcher
  • this differs from a quantitative study b/c the step are not linear and can go back and forth
30
Q

The sample in a qualitative study varies. how is it usually decided?
