“A systematic study of problems in patient care.”
Maghan Das
Abdellah
“A systematic detailed attempt to discover or confirm facts that relate to a specific problem to improve the practice and profession of nursing.”
Maghan Das
Polit and Hungler
“A systematic search for knowledge about issues of importance to nursing.”
Maghan Das
Henderson
“A study of the problems in practice relating to the effects of nursing.”

Ways to “use” nursing research:--journal clubs--critique research for patient care
purposes--explaining research to clients--data collection for others--reviewing methodology for IRB--finding research problems--using research results in patient
care or educationMaghan Das
Why do research?
Professionalism Accountability Social Relevance

Epistemology
Sources of Human Knowledge
or “how we know what we know”
Maghan Das
Sources of Knowledge
Tradition or tenacity Authority Experience Intuition Trial and Error Logical Reasoning
– Induction– Deduction
Scientific Method Maghan Das
Tradition/tenacity
Something we know because we have always known it.
Advantages:Efficient, provides a foundation of truths Disadvantages:Most traditions have not been evaluated
for their value
Maghan Das
Authority
We know a thing because some authoritative source says it is so
Authorities are not infallible, so always question authority--what is the evidence that this is true?
Maghan Das
Experience
Our own experiences may be too limited to generalize from
Maghan Das
Intuition
It just “ seems” right
Maghan Das
Trial and error
Haphazard unsystematic inefficient usually unrecorded must make the same mistakes or
discoveries over and over again
Maghan Das
Logical Reasoning Induction--developing generalizations from
specific observationsInduction
Specifics GeneralizationsDeduction
Deduction--developing specific predictions from general principles
Maghan Das
Scientific Method
The most advanced method of acquiring knowledge that humans have developed.
Maghan Das
Scientific Method
Order Control Empiricism Generalization Theoretical Formulation
Maghan Das
Order Systematic prescribed order in order to
have reproducibility and confidence in the results– problem identified– defined– predictions of oucome– information collected according to design– analysis – conclusion
Maghan Das
Control
In trying to isolate relationships among phenomena, scientists must control phenomena and factors not under study.
Maghan Das
Empiricism
Evidence rooted in objective reality and gathered directly or indirectly through the human senses.
Research is based in REALITY
Maghan Das
Generalization
No research is ever done just to benefit the subjects, in order to have value it must be generalizable to a wider population.
Maghan Das
Theoretical formulation
Theories are manner of organizing, integrating and deriving abstract conceptualization about the manner in which phenomena are interrelated.
Maghan Das
LIMITS OF SCIENTIFIC METHOD
1. Values or ethics 2. Human complexity 3. Measurement problems 4. Control 5. Ethical considerations
Maghan Das
PARADIGMS FOR NURSING RESEARCH ONTOLOGIC-What is the nature of reality? EPISTEMOLOGIC-What is the relationship
between the inquirer and that being studied?
AXIOLOGIC-What is the role of values in inquiry?
METHODOLOGIC-How should the inquirer obtain knowledge?
Maghan Das
POSITIVIST PARADIGM
Nature is ordered and regular and can be predicted.
Maghan Das
NATURALISTIC OR PHENOMENOLOGIC PARADIGM
Reality not fixed but exists within a context, many interpretations are possible. Nothing is absolutely true or false, only within a context.
Maghan Das
QUANTITATIVE RESEARCH vs
QUALITATIVE RESEARCH
Maghan Das
PURPOSES OF RESEARCH
Identification Description Exploration Explanation Prediction and Control
Maghan Das
Types of Research by Utility
BASIC RESEARCH
APPLIED RESEARCH
COMMERCIAL DEVELOPMENTMaghan Das
RELATIONSHIPS
CAUSAL vs ASSOCIATIONAL
Maghan Das
Requirements for causality
concomitant variation
temporal sequencing
absence of competing explanations

STEPS IN THE RESEARCH PROCESS(Quantitative Research)
Maghan Das
CONCEPTUAL PHASE
1. Formulating and Delimiting the Problem
2. Reviewing the Literature 3. Developing a Theoretical
Framework 4. Identifying the Research Variables 5. Formulating Hypotheses
Maghan Das
DESIGN AND PLANNING PHASE 6. Selecting a Research Design 7. Specifying the Population 8. Operationalizing the Variables 9. Conducting the Pilot
Study/Making Revisions
Maghan Das
EMPIRICAL PHASE
10. Selecting the Sample 11. Collecting the Data 12. Organizing Data for
Analysis
Maghan Das
ANALYTIC PHASE
13. Analyzing the Data 14. Interpreting the Results
Maghan Das
DISSEMINATION PHASE
15. Communicating Results
Maghan Das
STEPS IN THE RESEARCH PROCESS(Qualitative Research)
Circular and Flexible
Maghan Das
1. Define/Clarify Broad Topic 2. Review of the Literature? 3. Identify Site/Setting 4. Obtain Access 5. Obtain and Test Equipment 6. Begin Data Collection/Analysis 7. Identify Themes/Categories 8. Triangulation/Saturation 9. Formulate Hypotheses/Theories 10. Communicate Findings

TERMINOLOGY CONCEPTS/CONSTRUCTS CONCEPTUAL FRAMEWORK OPERATIONAL DEFINITION VARIABLES DATA HYPOTHESIS (research or null/statistical) PROBLEM STATEMENT RESEARCH DESIGNS SAMPLE/POPULATION
Maghan Das
Concepts/Constructs
Refined general or abstract idea“good health” “nursing care”
Maghan Das
Conceptual Framework
A series of concepts or ideas connected by statements about the relationships that exist among them
Maghan Das
Operational Definitions
Specifications of the specific and explicit operations which the researcher must perform in order to collect the required information
“Operationalizing the concept”
Maghan Das
Variables
Something which varies An abstract entity which takes on
different values.
Maghan Das
DATA
Pieces of information obtained in the course of the study
Maghan Das
Hypothesis
Research--A statement of the expectations of the researcher concerning the relationships of the variables under study HR
Null or Statistical--states that there is no relationship among the variables HO
Maghan Das
Problem Statement
A the research question or a statement about the purpose of the study.
Maghan Das
Research Designs
Basic designs are experimental and non experimental (or descriptive)
Maghan Das
Sample/Population
Sample--the subjects participating in the study
Population--the whole universe of possible subjects
Target population--the group to whom the researcher wishes to generalize the results of the study
