23
Q

Explain the 5 step research process

A

THINKING (id the problem/purpose and review the literature)
PLANNING (choose study design & approach to sample, data collection)
IMPLEMENTING (recruiting participants and collecting data)
ANALYZING (interpret findings)
INFORMING (disseminating results

24
Q

What are the 4 levels of research?

A

Descriptive
Correlational
Quasi-experimental
Experimental

25
Q

What is a descriptive survey?

A

NON-experimental research where descriptions of existing phenomena are collected in order to justify or assess current conditions or make plans for improvments

26
Q

What is a correlational study?

A

type of nonexperimental research that examines the relationship between two or more variables

27
Q

What does it mean when a study is quasi-experimental?

A

random assignment is not used, but the independent variable is manipulated and certain mechanisms of control are used.

28
Q

What 3 elements are necessary to create an experimental design?

A
  1. randomization
  2. control
  3. manipulation
29
Q

Which method of study has results that are meant to be able to generalize into other populations?

A

Quantitative

30
Q

Which research method tests theory?

A

Quantitative

31
Q

Which method of study develops theory?

A

Qualitative

32
Q

What is the difference between quantitative and qualitative studies?

A

QUANT: starts with a theory with a goal of testing said theory, highly controlled, use structured instruments and numbers and statistical analysis in order to make generalizations based on theory

QUAL: starts with phenomenon with the goal of developing a theory,
use communication and observation, words and unique interpretation to develop theory

33
Q

Name 3 types of quantitative studies

A
  • Randomized clinical Trial
  • survey research
  • evaluation research
  • meta-Analysis
34
Q

Name 3 types of Qualitative studies

A
  • phenomenology
  • ethnography
  • grounded theory
  • meta-synthesis
35
Q

What is the difference between an experimental and a non-experimental study? Give an example of each.

A

E: manipulates and controls variables and observes effect on other variables in an effort to evaluate cause and effect relationships
example: does a pre-op intervention program to increase self-efficacy affect self care measure post-op?

NON: describes relationships or correlation between variables that are NOT manipulated by the researcher
example: correlation between HRT and breast CA

36
Q

What type of study evaluates cause and effect relationships?

A

Quantitative Experimental design, randomized-control trial

37
Q

What is the difference between preliminary reading and comprehensive reading?

A

PRE: read to gain familiarity, focus on title and abstract, skim rest
COMP: read to gain understanding of the intent, the methods and the findings

38
Q

What does it mean to analyze a research article?

A

break the content into parts to understand each aspect of the study

39
Q

What is a synthesis?

A

pulling together or combining parts into a whole– to makes sense of it an explain relationships

40
Q

What is usually included in the discussion section of a research article?

A
  • major findings
  • limitations
  • conclusions, implications and recommendations
41
Q

What is a problem statement? What are the 3 necessary components?

A

an expression of a dilemma or disturbing situation that needs to be investigated

  1. nature
  2. context
  3. significance
42
Q

What are the 3 necessary components to a purpose statement? where do you normally find this in a research article?

A
  1. setting
  2. population
  3. variables
    * Normally found immediately prior to the methods section in an article
43
Q

What are the 3 necessary components to finding a researchable question?

A
  1. helps to solve a problem, add to theory or improve nursing practice
  2. Needs to be usable, current and clear
  3. Provides answers that will explain, describe, identify, predict or qualify
44
Q

A hypothesis MUST: (3 things)

A
  1. predict relationship between 2 or more variables
  2. be testable (observe, measure, analyze)
  3. be justifiable (based on theory or rationale)
45
Q

What kind of studies MUST include a formal hypothesis?

A

experimental studies (RCT)

46
Q

How do you know if there is an implied hypothesis?

A

If in the results section there is a “P” value, there is an implied hypothesis

47
Q

Give an example of a directional/non-directional relationship

A

Directional: pts who receive reconditioning have LESS bladder dysfunction than those who dont
NON-Directional: There is a difference in bladder function among pts with and without conditioning

48
Q

What are the 4 [8] types of hypotheses?

A
  1. Causal v associative
  2. Simple v complex
  3. directional v non-directional
  4. null v research
49
Q

What are independent variables?

A

Has the presumed effect on the dependent variable, may or may not be manipulated, CAUSE, ACTION, INTERVENTION

50
Q

What are dependent variables?

A

The consequence that varies with a change in the independent variable EFFECT, OUTCOME, REACTION, RESPONSE

51
Q

What are extraneous variables?

A

[confounding]- extra uncontrolled variables that influence the relationship being studied

52
Q

What is the difference between conceptual and operational definitions?

A

CONCEPT: the abstract, theoretical meaning of the concept being studied
OPERATIONAL” the means by which the researcher will collect information (only in quantitative studies)
