Nursing Research Definitions Diers n A systematic study

Nursing Research Definitions

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

Abdellah n “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 n “A systematic search for knowledge about issues of importance to nursing. ”

Henderson n “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 education

Why do research? n Professionalism n Accountability n Social Relevance

Conferences for Research Priorities

#1 through 1994 n n n n HIV Long term care Low birth weight Symptom management Nursing informatics Technology Health Promotion

#2 through 1999 n n n Develop and test community based nursing models Assess effectiveness of nursing interventions with HIV Develop and test approaches to remediate cognitive impairment Assess coping with chronic illness Methods for promoting immunocompetence

Epistemology n Sources of Human Knowledge or “how we know what we know”

Sources of Knowledge n n n n Tradition or tenacity Authority Experience Intuition Trial and Error Logical Reasoning – Induction – Deduction Scientific Method

Tradition/tenacity Something we know because we have always known it. n Advantages: Efficient, provides a foundation of truths n Disadvantages: Most traditions have not been evaluated for their value n

Authority n n 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?

Experience n Our own experiences may be too limited to generalize from

Intuition n It just “ seems” right

Trial and error n n n Haphazard unsystematic inefficient usually unrecorded must make the same mistakes or discoveries over and over again

Logical Reasoning Induction--developing generalizations from specific observations Induction Specifics Generalizations Deduction n Deduction--developing specific predictions from general principles n

Scientific Method n The most advanced method of acquiring knowledge that humans have developed.

Scientific Method Order n Control n Empiricism n Generalization n Theoretical Formulation n

Order n 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

Control n In trying to isolate relationships among phenomena, scientists must control phenomena and factors not under study.

Empiricism Evidence rooted in objective reality and gathered directly or indirectly through the human senses. Research is based in REALITY n

Generalization n No research is ever done just to benefit the subjects, in order to have value it must be generalizable to a wider population.

Theoretical formulation n Theories are manner of organizing, integrating and deriving abstract conceptualization about the manner in which phenomena are interrelated.

LIMITS OF SCIENTIFIC METHOD 1. Values or ethics n 2. Human complexity n 3. Measurement problems n 4. Control n 5. Ethical considerations n

PARADIGMS FOR NURSING RESEARCH n n 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?

POSITIVIST PARADIGM n Nature is ordered and regular and can be predicted.

NATURALISTIC OR PHENOMENOLOGIC PARADIGM n Reality not fixed but exists within a context, many interpretations are possible. Nothing is absolutely true or false, only within a context.

n QUANTITATIVE RESEARCH vs n QUALITATIVE RESEARCH

PURPOSES OF RESEARCH Identification n Description n Exploration n Explanation n Prediction and Control n

Types of Research by Utility n BASIC RESEARCH n APPLIED RESEARCH n COMMERCIAL DEVELOPMENT

RELATIONSHIPS CAUSAL vs ASSOCIATIONAL

Requirements for causality n concomitant variation n temporal sequencing n absence of competing explanations
