Nur 422 Flashcards
positivist (logical) paradigm
one objective reality exists out there and is waiting to be discovered.
naturalistic (constructivist) paradigm
there are many truths as we socially construct reality and different people have different perceptions and experiences.
phenomena
an observable observable occurrence, a fact, an event a situation, circumstance or happening; something that is impressive or extraordinary
concepts
an idea, thought or notion conceived in the mind.
meta-paradigm
Broad. Identitifies the basic subject matter of a discipline (person, environment, health, nursing)
Grand theory
explain large segments of the human experience; conceptual framework that defines broad perspectives of nursing.
middle-range theory
precise and focus on a portion of the human experience; moderately abstract and able to be tested.
nursing theory
conceptualization of some aspect of nursing communicated for the purpose of describing, explaining, predicting and/or prescribing nursing care.
Research Utilization (RU)
Applying research to nursing practice. Translating empirically based knowledge into real-world application.
Evidence Based Nursing Pracitce
Translating of scientific investigations and other types of knowledge into clinical practice.
site
overall location of the research
multisite
various places/locations where data is gathered. It offers a larger or more diverse group of participants.
settings
different places, where data is gathered. Naturalistic, partially controlled and highly controlled
research problem
a situation or circumstance that requires a solution to be described, explained, or predicted. It is an unsatisfactory situation that wants you to confront.
null hypothesis
a statement saying that there is no difference between/among groups or no systematic relationship between/among variables.
alternative hypothesis
predicts a relationship between the I.V. and the D.V.
experimental design
a procedure for devising an experimental setting such that a change in the D.V. may be solely attributed to a change in I.V.
manipulation
the researchers consciously vary the IV and then observe its effect on the DV.
Two types: basic and crossover
control
researchers introduce control, including the use of control group or comparison group
randomization
placing subjects at random - through randomization each subject has an equal chance of being in any group
Basic Design
randomizing subjects to different groups and subsequently measuring the D.V.
Two types: pretest-posttest and posttest only
Pretest-posttest design
classical controlled experiment. Golden standard
Posttest only design
No control over confounding variables that could have influenced the post-exposure measurements.
Subjects are randomly assigned.
Crossover Design
=Repeated measure design.
Exposing the same participants to more than one treatment. Subjects receive a sequence of different treatments (or exposure).
Quasi-experimental Design
Manipulation of an IV. Comparison between groups, time periods. No random assignment - matching instead.
Three types: Non-equivalent CG before and after, non-equivalent CG after-only, and time-series design.
Non-equivalent CG before-after design
non-equivalent groups assessed before and after intervention
Non-equivalent CG after only design
non-equivalent groups assessed only after intervention
Time series design
collecting data over an extended time period. No CG, or randomization.
Non-experimental
Observations - no intervention.
Types: Descriptive research and Correlational Studies
descriptive research
observe, descrive, and document aspects of a situation as it naturally occurs serve as a starting point for hypothesis generation or theory development.
Correlational Studies
Study relationships among variables but not to infer causal relationships.
Types: retrospective and prospective
Retrospective Design
a concept observed in the present is linked to concept occurring in the past
Prospective Design
start with a presumed cause and then go forward to the presumed effect
