COMPLETE SOLUTION
A researcher is studying self-efficacy in a population of mothers with
newborn babies. Due to the length of time of data collection, data is
collected from mothers anywhere from 5 days after giving birth to 4 weeks
after giving birth. What threat to internal validity does this situation
represent? - ANSWERS-Maturation
A quantitative instrument can be reliable without being valid. - ANSWERS-
TRUE
Which of the following measures of validity concerns whether an instrument
has the appropriate sample of items for the construct being measured? -
ANSWERS-Content validity
External validity refers to the ability to generalize results from a research
study sample to a larger population. - ANSWERS-TRUE
Identify common threats to internal validity. (Select all that apply) -
ANSWERS-Selection, History, Mortality, Maturation
Internal validity measures the research: - ANSWERS-results for accuracy.
What important aspects of validity should an instrument or scale examine?
(Select all that apply.) - ANSWERS-Construct validity, Criterion-related
validity, Content validity
, Identify common threats to external validity. (Select all that apply.) -
ANSWERS-Reactivity, Novelty, Experimenter
External validity is important to evidence-based practice (EBP) because it
allows researchers to: - ANSWERS-generalize evidence from controlled
settings to real-world practice settings.
A nurse researcher has developed and tested a new instrument. Which of the
following coefficient alpha results indicates that the researcher's instrument
is highly reliable? - ANSWERS-0.82
A nurse researcher is deciding whether or not to utilize a mixed methods
(MM) research design for an evidence-based practice project. Which
statements about an MM research design are true? (Select all that apply.) -
ANSWERS-MM research can be used to generate and test a hypothesis., MM
research can be used to help to confirm a theory.
A researcher studied the impact that stress had on students in a nursing
program. One hundred bachelor of science in nursing students completed
the Perceived Stress Scale. Twenty students then volunteered to discuss the
issue of stress as part of a focus group. The data sets were analyzed
separately, and then the results were combined and interpreted. Which is the
correct term for the design used for this MM research? - ANSWERS-
Convergent parallel design
A nurse researcher is reading an MM-designed research article. The nurse
researcher would know which notation identifies a study as MM with equal
qualitative and quantitative sections? - ANSWERS-QUAL/QUAN
A nurse limits researching evidence-based articles to quantitative studies
only. What does this approach do? - ANSWERS-Prevents a holistic view of the
issue.
