Define a study. When researchers answer a question through disciplined
research. AKA investigation
What are the two sets of people involved in -Researcher/investigator: Those who do the research
studies with humans? -Those who provide the information
What are the people who provide -Quantitative: Subject/Participant/respondent
information in a quantitative study called? -Qualitative: Study participant/informant/key informant
What about qualitative?
What are the terms to describe abstractions -Quantitative: concepts, constructs, variables
of particular aspects of human -Qualitative: Phenomena, concepts, constructs
characteristics and behaviors? In what kind
of study is each term used (quantitative or
qualitative).
Give 3 examples of concepts/phenomena. Pain, fatigue, resilience
When would "construct" be used in replace Construct refers to a slightly more complex abstraction that is
of "phenomena" or "concept"? Give an deliberately invented. Ex. self care
example.
Define a theory. An explanation of some aspect of reality. Concepts are
knitted together into a coherent system to describe or explain
some aspect of the world.
What is the role of a theory in quantitative Researchers start with a theory and, using deductive
research? reasoning, make predictions about how phenomena would
behave in the real world if they were true. The specific
predictions are then tested in a study, and the results are used
to support or challenge the theory.
What is the role of a theory in qualitative Theory is often a product of the research. The investigators
research? use information from study participants inductively to develop
a theory rooted in the participants experiences.
, What is a variable? Which kind of study A variable is any quality of a person, group, or situation that is
utilizes variables? different from another person, group, or situation or takes on
different meanings. Quantitative researches utilizes variables
and seeks to understand how or why things vary, and to learn
how differences in one variable relate to differences in
another. Weight, anxiety, fatigue are variables.
Are variables always inherent human -Characteristics: weight, anxiety, fatigue
characteristics or an variables be created? -Created: A researcher can test the effectiveness of PCA
Give examples. compared to IM analgesia in relieving pain after surgery.
Some patients would be given PCA, some would be given IM.
How can variables be represented (3 ways)? -On a continuum: age
Give examples. -Few values: number of children
-Categories: blood type
Differentiate between independent and -Independent: the presumed cause, I (intervention, influence,
dependent variables. Which part of PICO or exposure) and C (comparison)
do these variables correspond to? -Dependent: the presumed effect, O (outcome), what
researchers want to understand, explain, or predict
Give 2 examples of studies involving -Researchers investigate the extent to which lung cancer
dependent and independent variables. (dependent variable) depends on smoking (independent
variable).
-Investigators examine the extent to which patients pain
(dependent variable) depends on different nursing actions
(independent variable)
When it does not make sense to infer a Direction of influence. If we compared levels of depression
cause and effect connection between (DV) among men and women (IV) diagnosed with pancreatic
dependent and independent variables, what cancer and found men to be more depressed, we could not
else can these terms be used to describe? conclude that depression was caused by gender. Instead, we
Give an example. could say that the direction of influence runs from gender to
depression.
Are variables inherently dependent or No, a dependent variable in one study may be an
independent? Explain with an example. independent variable in another study and vice versa.
-Ex: Study 1 examines the effect of an exercise intervention
(independent) on the development of osteoporosis
(dependent). Study 2 investigates the effect of osteoporosis
(independent) on bone fracture incidence (dependent).
Differentiate between setting, study sites, -Setting: Types of place where information is gathered
and multisite studies. Give examples of (Hospitals, homes)
each. -Study Site: the specific location for the research (Haitian
neighborhood in Miami)
-Multisite study: multiple study sites are used to offer a larger
and more diverse sample of participants (multiple clinics in
Connecticut)
Differentiate between a conceptual -Conceptual: The abstract or theoretical meaning of a
definition and an operational definition of a concept being studied, even if it is a seemingly
concept. straightforward term.
-Operational: the operations (measurements) a researcher
must perform to measure the concept and collect the desired
information.
