Q

what is the conceptual phase of a quantitative study?

A
  • identifying a problem, determining study variables, and determining clinical
    relevance, methodological issues, and ethical issues.

Q

what is the design and planning phase of a quantitative study?

A
  • the design phase begins by determining how often data will be collected,
    how to reduce bias, and how to structure and control the study. An intervention protocol is developed to specify what the intervention and alternative will be for comparison.
    -The researchers define the population

Q

during which phases of quantitative study is literature review performed?

A

conceptual

18
Q

what can help define the concepts during the conceptual phase of a quantitative study?

A

a theory or framework

19
Q

in what phase of quantitative study do you provide hypothesis

A

conceptual

20
Q

what is the empirical phase of a quantitative study?

A

the empirical phase consists of collecting data according to a pre-planned method in the design phase.

21
Q

during which phase of quantitative study is data collected and coded into numerical values?

A

empirical

22
Q

what is the analytic phase of a quantitative study?

A

the analytic phase involves using a formal method of statistical analysis on the
collected data.

23
Q

The clinical significance as well as conclusions related to the clinical significance are discussed during which phase

A

analytic

24
Q

what is the dissemination phase of a quantitative study?

A

preparing a research report and eventually using the evidence in practice.

25
Q

What are the 3 theoretical background for a QUALITATIVE study?

A
  1. grounded theory
  2. phenomenology
  3. ethnography
26
Q

what is grounded theory ?

A

-qualitative research framework
-seeks to understand and describe social psychological processes; find a core
variable to explain what is happening in a social scene
Ex. A study that measures how mental health users transitioned from the hospital to home.
The study identified the core variable as the patient’s management of preconceived expectations.

27
Q

what is phenomenology?

A

-qualitative research framework
concerned with the lived experiences of humans. It seeks to understand how a
person or group of people perceive an experience they endured
Ex. For instance, a phenomenological study could be conducted on students’ experiences going to clinical during a pandemic.

28
Q

what is ethnography?

A

-qualitative research framework
-studies the patterns and lifeways of a defined cultural group in a holistic fashion.
In this type of study, the researcher joins a group and observes their behavior.
Ex. Researchers immersing in two nursing homes to observe how the staff manages
unpleasant resident behaviors.

29
Q

Do qualitative study steps have a linear flow?

A

HECK NO. its goes back n forth

30
Q

What are the steps to a qualitative study?

A 
research problem 
literature review
research site/environemnts
overall approach
ethics
drawing conclusions

PLSOED
problem, lit, site, overall,ethics, drawing con)

31
Q

what is the research problem in a qualitative study?

A

A broad area that little is known about is selected initially that can later be focused once thestudy has began

32
Q

does a qualitative study have to have a literature review?

A

Nope. sometimes researchers think other studies might influence their findings

33
Q

Why do qualitative studies have a research site/ environment step in the study process?

A

Since qualitative studies require human experiences and perspectives an appropriate environment needs to be defined. For some sites the researcher may need to get approval from an entity before going.

34
Q

what is the overall approach step of the qualitative study?

A

In a qualitative study data collection can occur before a design is finalized, and the design can change based on the data collection.

35
Q

what is the ethics step of a qualitative study?

A

-important

Ethical issues are just as important in qualitative studies and need to be addressed since participants develop a rapport with the researcher.

36
Q

How is the data organized in a qualitative study? When is it organized?

A
  • participants responses or narratives are collected and grouped together
    into themes or categories
  • The sample in a qualitative study varies and usually is decided when narratives become redundant or the results are saturated.

-during the “drawing conclusions phase”

37
Q

During the drawing conclusion phase, how do reviewers assess accuracy of their data?

A

sometimes they have to go back to participants to verify their analysis is congruent with participant experience

38
Q 
Which term is exclusive to quantitative research?
A) study participant
B) researcher
C) variables
D) data
A

Answer: C, variables.

Variables are exclusive to quantitative research. The other terms are used with both types of research.

39
Q 
A researcher investigated the effects of haloperidol on reducing delirium in the intensive care unit.  What is the dependent variable?
A) haloperidol
B) delirium
C) intensive care unit
D) researcher
A

Answer: B, delirium.

The independent variable or change is haloperidol. The dependent variable or outcome is the delirium. The ICU and researcher are not variables in the study.

40
Q 
A researcher measured stress levels numerically between a group of nursing students versus a group of accounting students.  What type of study is this?
A) observational
B) clinical trial
C) ethnographic
D) grounded theory
A

Answer A, observational.

The study does not introduce an intervention or change. It measures stress between two groups of individuals and would be a non-experimental study or an observational study. A clinical trial would have an intervention. Ethnographic and grounded theory are qualitative studies.

41
Q 
Which of the following is component of the conceptual phase of conducting a quantitative study?
A) data collection
B) data analysis
C) review of literature
D) dissemination of findings
A

Answer: C, review of literature.

The review of literature is part of the conceptual phase. Data collection is part of the empirical phase. Data analysis is part of the analytic phase, and dissemination of findings is part of the dissemination phase.

42
Q 
What is one difference in qualitative and quantitative research?
A) Addressing ethical issues
B) Identifying a research problem
C) Collecting Data
D) Sample size determination
A

Answer D, sample selection.

The sample in a quantitative study is defined before the study begins, but in a qualitative study the sample size is determined after data saturation occurs.

Both studies have to address ethical issues, identify a research problem, and collect some form of data. The type of data is different, but without data neither would be a research study.
