What are the two ways nurses participate in research? What specific actions will a nurse take in each of these roles?
1. Consumer: read research to keep current in practice
2. producer: actively design & carry out studies
� Ways to engage in research:
Ideas for a clinical inquiry
Collect research information
Advise clients about participating
in a study
Search for resear
What was the first journal published to help propel research in nursing? When was it published (decade)?
Nursing Research, 1950's
How did the NIH and NINR help to promote nursing research?
NIH promoted and financially supported research projects and training related to patient care.
NINR helped put nursing research more into the mainstream of research activities enjoyed by other health disciplines.
What are the sources of evidence for nursing research? Give examples.
- Tradition & Authority: weakest, don't want to use, based on untested things
- Clinical Experience: trial & error
- Assembled info: statistics
- Disciplined research: best source of information
a worldview, a general perspective on the world's complexities; how you choose to view the world
What are the two main types of Paradigms?
positivist & constructivist
assumption of positivist paradigm
there is a reality out there that can be studied and known; the world is driven by real, natural causes
characteristics of positivist paradigm
Research is aimed at understanding the underlying causes of natural phenomena
Positivists prize objectivity; bias is put aside
Use an orderly, disciplined approach to research with tight controls
Very rational, scientific
key concepts of positivist paradigm
1. reality exists
2. there is objectivity & things are quantifiable (can out a number to it)
3. work on a pre-specified design
assumption of constructivist paradigm
knowledge is maximized when the distance between the inquirer and participants in the study is minimized.
characteristics of constructivist paradigm
� During research, the researcher and subject interact
� Subjectivity and values are inevitable and desirable
- believe there's different versions of reality based on personal experience (reality isn't fixed)
- in the middle of it, personal
Define Scientific Method
collection of data in orderly & systematic way

1. Quality & Nature of the research: Limited availability of strong research evidence for some practice areas & need for research that directly address pressing clinical problems and for replicating studies in a range of settings remains a challenge
two main categories of Pre-Appraised Evidence?
systematic reviews & clinical practice guidelines and care bundles
Provides a review of all key evidence on a topic to answer EBP questions
More rigorous than a literature review
Various forms: Narrative integration
- summary of someone else's report
clinical practice guidelines & care bundles
CPG-distill a body of evidence into a usable format
Often based on systematic reviews
Care Bundle-encompasses a set of interventions to treat or prevent a specific cluster of symptoms
Find by searching guideline databases
Evaluate using appraisal instrume

Is it justified to implement this change?
-Implementing and evaluating the innovation:
The outcome the researchers want to understand, explain, or predict. Corresponds with the Outcome in the PICO question.
The presumed cause; Corresponds with the Intervention plus the Comparison in the PICO question. What we manipulate

A relationship between two variables wherein the presence or value of one variable (" the cause") determines the presence or value of the other ("the effect")
What are two types of Quantitative research and what is the goal of each of these?
- Experimental: Researchers actively introduce an intervention or treatment; ex:
For patients undergoing laparoscopic surgery, does music use decrease pain levels post operatively?
- Non-experimental: Researchers collect data without introducing treatment
identify and define three disciplines of qualitative research.
� Grounded Theory: Seeks to describe and understand key social psychological processes
� Phenomenology: Concerned with the lived experiences of humans
� Ethnography: Studies the patterns of lifeways of a defined cultural group in a holistic fashion

Phase 2: design and planning
How does the implementation of a qualitative research study differ from that of a qualitative study?
Quantitative: linear progression of tasks- researchers plan what steps to take and then follow those steps.
Qualitative: progression is closer to a circle than a straight line. Qualitative researchers continually examine and interpret data and make decisi
In Qualitative studies, when do researchers stop collecting data? How do the researchers know when to stop collecting data?

Refers to the accuracy and consistency of information obtained in a study
Associated with the methods used to measure variables
The soundness of the study's evidence
Important criterion for evaluating methods to measure variables
Encompasses several different dimensions- credibility, transferability, confirmability, dependability, and authenticity
Achieved when research methods inspire confidence that the results are truthful and accurate
The use of multiple sources or referents to draw conclusions about what constitutes the truth
refers to the application and combination of several research methods in the study of the same phenomenon
Combining multiple observers, theories, methods, and em
A distortion or influence that results in an error in inference
- Systematic- when the bias consistent or uniform
- Bias reduction- randomness (chance), binding (masking)
No systematic biases, all participants are in an initial pool have an equal chance of being selected
Also called masking
Used in some quantitative studies to prevent biases stemming from people's awareness
Involves concealing information from participants, data collectors, or care providers to enhance objectivity
Ex: getting a placebo drug
