Q

When a researcher has an idea for research they must ask themselves if this idea is systematically defined, does it have the potential to generate new knowledge?

A

They answer this question by reviewing the scientific literature; this process is called conducting a systematic review of the lit.

Q

Dissemination (Sharing)

A

Writing a journal article to share results/finding (new knowledge) with the scientific community

19
Q

Sampling

A

the way a researcher selects study participants

20
Q

Data Colection

A

types of data and how it is collected

21
Q

Data Analysis

A

how the data is looked at.

22
Q

Scientific Merit

A

The combo of the terms research and systematic investigation.

  1. Proposed research meets the definition of research
  2. Must be conducted by a qualified researcher
  3. Study builds on prior research
  4. Is a systematic investigation that once the study has been concluded, new knowledge will be generated.
    - All studies are judged for scientific merit.
    - Must have problem statement, purpose statement, research questions, and design and methods
23
Q

Institutional Review Board (IRB)

A

Primary purpose is to ensure that the human subjects are being treated ethically.
-Reviews study’s scientific merit

24
Q

Basic Research

A

Seeks to enhance overall knowledge about the “physical, biological, psychological, or social world or to shed light on historical, cultural, or aestehtic phenomena. goal is to generate new knowledge to increase understanding

25
Q

Applied/Clinical Research

A

Applied research is the type of research that seeks to study issues that have “immediate relevance to current practices, procedures, and policies”

-Clinical research is applied research conducted in the health care arena with the primary focus of finding practical solutions to improve patient care/clinical outcomes.

the only distinction between the two is the setting.
goal is to generate new knowledge that will change policy, procedures, and practices

26
Q

4 Purposes of research

A
  • Exploratory
  • Descriptive
  • Evaluative
  • Explanatory
27
Q

Exploratory

A

explore or investigate to determine the scope of an issue or to understand a problem that has not be clearly defined.

28
Q

Descriptive

A

describe the problem. The who, what, where, and when, how many?

29
Q

Evaluative

A

how well is this working?

30
Q

Explanatory

A

determine a cause and effect relationship.

31
Q

How does one choose the correct research type, purpose, research design, and methods?

A

Through the exploration of a researchers philosophical thought processes

32
Q

Paradigm

A

Paradigm is the researcher’s beliefs about truth, knowledge, and the correct actions to undertake in the pursuit of new knowledge.
Knowing which paradigm a researcher is working under will yield which research methodology the researcher will select

33
Q

4 Paradigms

A

Positivism
Post-Positivism
Constructivism
Pragmatism

34
Q

Positivism

A
  • cause and effect relationships exist, the researcher must control for variables, and research can be free from bias and values.
  • absolutely proves cause and effect relationship
  • very similar to post positivism in that both use quantitative methodology
35
Q

Post Positivism

A
  • truth exists in natural scientific laws, but it might not be possible to control for every variable. While it’s important to control for bias, total elimination might not be possible.
  • finds statistical proof of a cause-and-effect relationship
  • hesitate to say that they have absolutely, undeniably proved something
  • open to retesting an revision
  • governs most health science quantitative research
36
Q

Constructivism

A
  • there is no one truth rooted in natural laws; rather truth is fluid and rooted in societal constructs and researcher works directly with participants to explore meaning.
  • explores different perspectives to find meaning about the human experience
  • does not need to find one truth but the whole truth gleaned from participants experiences
  • value inductive explorations
  • Qualitative
37
Q

Pragmatism

A
  • truth is the result of both natural laws of nature and peoples’ subjective realities.
  • combines both ways of searching for truth to yield a greater understanding of the issue
  • Mixed methods (both qualitative and quantitative)
  • combining methods of data collection and analysis to generate deeper and broader insights, to develop important knowledge claims of a wider range of interest and perspectives
  • allows flexibility to select designs, techniques, procedures, and data collection that provide results (mixed methods)
  • subjective and objective
  • focus on what works
38
Q

Quantitative Methodology

A

Quantitative research involves the collection, analysis, and interpretation of numerical data to explain, predict and/or control phenomenon of interest.

39
Q

Qualitative Methodology

A

Qualitative research involves the collection, analysis, and interpretation of narrative and visual data in order to gain insights into a particular phenomenon of interest.

40
Q

Mixed Methods

A

Uses both quantitative and qualitative methodologies.

41
Q

Deductive reasoning

A
  • Works from the more general to the more specific.
  • Hypothesis testing – theory, test theory, results support/refute theory.
  • Quantitative researchers also use deductive reasoning by employing the scientific method
  • ruling out diagnoses by testing
42
Q

Inductive Reasoning

A
  • Qualitative researchers use this but can also be applied to quan.
  • Inductive reasoning = few observations builds general understanding of an issue
  • Findings from these observations are not tested simply offered as an explanation of what is occurring or why something is occurring
  • apply the finding from a few observations to build a general understanding to a larger population
  • common when there is a lack of preexisting theory
  • observations are not tested, they are offered as an explanation of what is occurring or why
  • used when scientific method is impossible or unethical
  • qualitative
43
Q

Generalizable results

A
  • a comment on to what extent the study results are likely to apply in other study settings
  • only relevant to quantitative research
  • not all quantitative research studies achieve generalizable results, meaning the results of the study might only be applied to one group and might not be valid for other groups or study settings.
