What is research?
 A systematic process of inquiry
 Goal directed
 Focused on uncovering new
  knowledge to help understand
  phenomena, answer questions, or
  address problems
Research

• Research means “ to search again or
  carefully examine” (Langford 2001).

• “A systematic study of problems in
  patient care.”
                            - Diers



              Dr. R S Mehta, MSND, BPKIHS   5
Abdellah
• “A systematic detailed attempt
  to discover or confirm facts
  that relate to a specific problem
  to improve the practice and
  profession of nursing.”
Polit and Hungler
• “A systematic search for
  knowledge about issues of
  importance to nursing.”
Henderson
• “A study of the problems in
  practice relating to the effects
  of nursing.”
What makes nursing research?

Nursing research is
 “a scientific process that validates
 and refines existing knowledge and
 generates new knowledge, which
 directly and indirectly influences
 nursing practice”

                 (Burns & Grove, 2005)
Definition of Nursing Research…

TYPES OF RESEARCH
        &
RESEARCH DESIGNS



     Dr. R S Mehta, MSND, BPKIHS   27
Types of Study Design:
• There is no best type of study design

• The context, assumptions,
  paradigms and perspectives decide
  the type of research methodology

Note: CRD-complete random design, RBD-random block design, FD- factorial design 29
4 Types of Research
•   Basic research
•   Applied research
•   Action research
•   Evaluation research




                Dr. R S Mehta, MSND, BPKIHS   30
Basic Research
• Also known as fundamental research
  (sometimes pure research) is research carried
  out to increase understanding of fundamental
  principles.
• Many times the end results have no direct or
  immediate commercial benefits
• Basic research can be thought of as arising out of
  curiosity.
• However, in the long term it is the basis for many
  commercial products and applied research.
• Basic research is mainly carried out by
  universities    Dr. R S Mehta, MSND, BPKIHS      31
Applied Research
• Concern with addressing problem of the world
  as they are perceived by participants,
  organization or group of people
• Action oriented and aims to assess, describe,
  document or inform people concerned about the
  phenomenon under investigation
• Findings are intended to have immediate and
  practical value
• In the field of education, policy, evaluation and
  contract are all examples of applied research
                 Dr. R S Mehta, MSND, BPKIHS      32
Action Research
Action Research is simply a form of self-reflective
enquiry undertaken by participants in social
situations in order to improve the rationality and
justice of their own practices, their understanding
of these practices, and the situations in which these
practices are carried out.

                  Wilf Carr and Stephen Kemmis (1986)




                  Dr. R S Mehta, MSND, BPKIHS           33
Evaluation research
• Major concern is practical application
• Tends to be viewed as an isolated case study
  though the methodologies may be transferable
• Rooted in values and politics
• Is immediately prescriptive based upon logic and
  experience
• Reports are written for implementers, users and
  other interested people
• The extent of dissemination is controlled by
  sponsor
                 Dr. R S Mehta, MSND, BPKIHS    34
RESEARCH DESIGNS
 QUANTITATIVE                    QUALITATIVE
• Experimental study • Ethnography
• Quasi-              • Case study
  experimental study • Historical study
• Survey study
• Correlational study


              Dr. R S Mehta, MSND, BPKIHS      35
Experimental Design
• Test whether an educational practice or
  idea makes a difference for individuals




              Dr. R S Mehta, MSND, BPKIHS   36
Randomized Controlled Trials
• Similar groups of individuals from same source
  population are allocated at random to receive or
  not to receive an intervention, then observed for
  occurrence of outcome(s).

                                                38
CASE-CONTROL STUDIES
SOME KEY POINTS
• Frequently used study design
• Participants selected on the basis of whether or
  not they are DISEASED (remember in a cohort
  study participants are selected based on
  exposure status)
• Those who are diseased are called CASES.
• Those who are not diseased are called
  CONTROLS.
                 Dr. R S Mehta, MSND, BPKIHS    39
Cross-Sectional Study
                Disease

Exposure   yes                no           total

yes         a                  b           a+b

no          c                  d           c+d

             Dr. R S Mehta, MSND, BPKIHS           40
Cohort Studies
Group by common characteristics
Start with a group of subjects who lack a positive
history of the outcome of interest yet are at risk
for it (cohort).
Think of going from cause to effect.
The exposure of interest is determined for each
member of the cohort and the group is followed
to document incidence in the exposed and non-
exposed members.


                Dr. R S Mehta, MSND, BPKIHS       41
When is a cohort study
        warranted?
• When good evidence suggests
  an association of a disease with
  a certain exposure or exposures
 e.g. Smoking & Lung Cancer.



               Dr. R S Mehta, MSND, BPKIHS   42
True, Qusi, & Pre-
      Experimental Study
Randomization, Control and Manipulation


• True exp.: All 3: R C M
• Quasi exp.: M + R or C
• Pre exp.: M, no R & no C
             Dr. R S Mehta, MSND, BPKIHS   43
Correlational Study
• Focus more on examining the association or
  relation of one or more variables within a
  single group of individuals
• Researcher measures the degree of
  association or relation between two or more
  variables using the statistical procedure of
  correlational analysis
• Degree of association indicates whether the
  two variables are related or whether one can
  predict another
                Dr. R S Mehta, MSND, BPKIHS   44
Survey Designs
• Describe trends in a large population of
  individuals
• Administer a survey or questionnaire to a
  small group of people (sample) to identify
  trends in attitudes, opinions, behaviors or
  characteristics of a larger group of people
  (population)


               Dr. R S Mehta, MSND, BPKIHS      45
Descriptive Research Design:
  • Describe facts
  • Discover new facts
  • Not invent new theory and methods
  • Largest effort given on data
    collection
  • It answers questions: satisfy
    curiosity
  • Solve problems
Qualitative Research
      Dr. R S Mehta, MSND, BPKIHS   47
Choice of Colours




• 1. What colour would you like the most?

              Dr. R S Mehta, MSND, BPKIHS   48
2.What do you associate this colour with?
    Good luck
    love
    Confidence
    Truthfulness
    Lively
    Danger
    …


               Dr. R S Mehta, MSND, BPKIHS   49
3. What is the source of this knowledge?
  – Own Idea
  – Own Belief
  – Own observation
  – Own experiences
  – Cultural and Traditional
  – Books & articles
  – etc

              Dr. R S Mehta, MSND, BPKIHS   50
• Not every thing can be quantified.
• Some valuable ideas, opinions,
  perceptions, experiences, behaviours,
  qualities can be described only in
  words
• These subjective things are shared
  between people, but the meanings may
  be distorted in the process of
  communication and recording.


              Dr. R S Mehta, MSND, BPKIHS   51
• Although subjective, these
  aspects often add richness and
  depth
• The art of the doctor and the
  experience of being human are
  aspects that need a qualitative
  approach to
  investigate/research properly.
           Dr. R S Mehta, MSND, BPKIHS   52
Definitions
• Quantitative Research - investigation in which
  the researcher attempts to understand some
  larger reality by isolating and measuring
  components of that reality without regard to their
  contextual setting.

• Qualitative Research - investigation in which the
  researcher attempts to understand some larger
  reality by examining it in a holistic way or by
  examining components of that reality within their
  contextual setting.
                  Dr. R S Mehta, MSND, BPKIHS      53
Qualitative Research
– Human understanding and
   interpretation define reality
– Complex reality can be understood and not
  as simply a sum of its parts
– Goal of research is to examine complex
  phenomena to define the reality within
– To be meaningful, inquiry must be holistic
  and contextual
Characteristics of Qualitative
             Research
•   Purpose is understanding
•   Oriented toward discovery
•   Uses subjective data
•   Extracts meaning from data
•   Interprets results in context
•   Focus is holistic
Disadvantages of Qualitative
            Research
• Subjectivity leads to procedural problems
• Replicability is very difficult
• Researcher bias is built in and unavoidable
• In-depth, comprehensive approach to
  data gathering limits scope
• Labor intensive, expensive
• Not understood well by “classical”
  researchers

Advantages of Qualitative Research
 In-depth Examination of Phenomena
    (Phenomenological Study/Research)
 Uses subjective information
 Not limited to rigidly definable variables
 Examine complex questions that can be
 impossible with quantitative methods
 Deal with value-laden questions
 Explore new areas of research
 Build new theories           Dr. R S Mehta, MSND, BPKIHS 58

              Dr. R S Mehta, MSND, BPKIHS     59
Meta Analysis
• Statistically combines results of existing
  research to estimate overall size of
  relation between variables

• Helps in
  • Developing theory
  • Identifying research needs,
  • Establishing validity

• Can replace large-scale research studies
• Better than literature reviews

    4 Types ofResearch • Basic research • Applied research • Action research • Evaluation research Dr. R S Mehta, MSND, BPKIHS 30
  • 31.
    Basic Research • Alsoknown as fundamental research (sometimes pure research) is research carried out to increase understanding of fundamental principles. • Many times the end results have no direct or immediate commercial benefits • Basic research can be thought of as arising out of curiosity. • However, in the long term it is the basis for many commercial products and applied research. • Basic research is mainly carried out by universities Dr. R S Mehta, MSND, BPKIHS 31
  • 32.
    Applied Research • Concernwith addressing problem of the world as they are perceived by participants, organization or group of people • Action oriented and aims to assess, describe, document or inform people concerned about the phenomenon under investigation • Findings are intended to have immediate and practical value • In the field of education, policy, evaluation and contract are all examples of applied research Dr. R S Mehta, MSND, BPKIHS 32
  • 33.
    Action Research Action Researchis simply a form of self-reflective enquiry undertaken by participants in social situations in order to improve the rationality and justice of their own practices, their understanding of these practices, and the situations in which these practices are carried out. Wilf Carr and Stephen Kemmis (1986) Dr. R S Mehta, MSND, BPKIHS 33
  • 34.
    Evaluation research • Majorconcern is practical application • Tends to be viewed as an isolated case study though the methodologies may be transferable • Rooted in values and politics • Is immediately prescriptive based upon logic and experience • Reports are written for implementers, users and other interested people • The extent of dissemination is controlled by sponsor Dr. R S Mehta, MSND, BPKIHS 34
  • 35.
    RESEARCH DESIGNS QUANTITATIVE QUALITATIVE • Experimental study • Ethnography • Quasi- • Case study experimental study • Historical study • Survey study • Correlational study Dr. R S Mehta, MSND, BPKIHS 35

    Cohort Studies Group bycommon characteristics Start with a group of subjects who lack a positive history of the outcome of interest yet are at risk for it (cohort). Think of going from cause to effect. The exposure of interest is determined for each member of the cohort and the group is followed to document incidence in the exposed and non- exposed members. Dr. R S Mehta, MSND, BPKIHS 41

  • 44.
    Correlational Study • Focusmore on examining the association or relation of one or more variables within a single group of individuals • Researcher measures the degree of association or relation between two or more variables using the statistical procedure of correlational analysis • Degree of association indicates whether the two variables are related or whether one can predict another Dr. R S Mehta, MSND, BPKIHS 44
  • 45.
    Survey Designs • Describetrends in a large population of individuals • Administer a survey or questionnaire to a small group of people (sample) to identify trends in attitudes, opinions, behaviors or characteristics of a larger group of people (population) Dr. R S Mehta, MSND, BPKIHS 45
  • 46.
    Descriptive Research Design: • Describe facts • Discover new facts • Not invent new theory and methods • Largest effort given on data collection • It answers questions: satisfy curiosity • Solve problems

    • Not everything can be quantified. • Some valuable ideas, opinions, perceptions, experiences, behaviours, qualities can be described only in words • These subjective things are shared between people, but the meanings may be distorted in the process of communication and recording. Dr. R S Mehta, MSND, BPKIHS 51
  • 52.
    • Although subjective,these aspects often add richness and depth • The art of the doctor and the experience of being human are aspects that need a qualitative approach to investigate/research properly. Dr. R S Mehta, MSND, BPKIHS 52
  • 53.
    Definitions • Quantitative Research- investigation in which the researcher attempts to understand some larger reality by isolating and measuring components of that reality without regard to their contextual setting. • Qualitative Research - investigation in which the researcher attempts to understand some larger reality by examining it in a holistic way or by examining components of that reality within their contextual setting. Dr. R S Mehta, MSND, BPKIHS 53
  • 54.
    Qualitative Research – Humanunderstanding and interpretation define reality – Complex reality can be understood and not as simply a sum of its parts – Goal of research is to examine complex phenomena to define the reality within – To be meaningful, inquiry must be holistic and contextual
  • 55.
    Characteristics of Qualitative Research • Purpose is understanding • Oriented toward discovery • Uses subjective data • Extracts meaning from data • Interprets results in context • Focus is holistic
  • 56.
    Disadvantages of Qualitative Research • Subjectivity leads to procedural problems • Replicability is very difficult • Researcher bias is built in and unavoidable • In-depth, comprehensive approach to data gathering limits scope • Labor intensive, expensive • Not understood well by “classical” researchers

Editor's Notes

  • #5 In order to begin to identify research problems is it first necessary to understand what is meant by the term research and to have an understanding of how the research problem fits into the whole research process. A number of different definitions for research exist however common to all of them is an agreement that research is systematic, disciplined and focused on gathering information to understand a phenomena, answer questions or solve research problems. The systematic nature of the research process means that research is undertaken in a methodological fashion using a rigorous approach to collect information (data) about a phenomena or research problem and to analyze and interpret that information in order to begin to answer questions or solve problems. Since research is directed at ultimately helping us to answer a question or address a problem, it is critical that we are as clear as possible about the research problem we are interested in. Thus, developing a problem statement is a critical first step in the research process.
  • #10 Nurses are interested in developing, evaluating and implementing research evidence that is important to us as professionals. This definition by Burns and Grove suggests that nursing research is a systematic inquiry which is directly or indirectly related to nursing practice. This broad view of nursing research suggests that the focus of research in nursing is shaped by phenomena of interest to nurses such as individual and family response to illness as well as nurses roles in impacting care. In addition, nursing research might also address other domains of practice including education, administration and multidisciplinary collaboration. When planning a research project it is important to choose a topic that has relevance to your area of interest and that has the potential to add to our understanding of an important nursing issue. This topic will ultimately be refined into a problem statement that can be used to direct the research process.
