Question 1
pts
Correct!
A researcher develops a new instrument to measure coping skills and conducts a
pilot study to compare the new tool with an existing tool that measures this
concept.
Convergent validity
Correct!
A researcher performs a series of pilot studies to evaluate whether a
measurement tool produces consistent results.
Reliability
Correct!
A researcher develops a 7-point Likert scale to evaluate feelings of well-being in
patients who are undergoing chemotherapy. The researcher administers this
measure to other, similar patients in other medical centers.
Test -retest reliability
Correct!
In a research study, ambulatory clinic nurses teach children with asthma how to
monitor peak expiratory flow volumes and how to use metered-dose inhalers to
determine whether asthma control scores improve. The researcher discovers
inconsistencies in how these measures were taught and how well the children
understood the concepts.
Intervention fidelity
Correct!
A researcher reviews demographic characteristics of potential study subjects,
such as age and gender, to determine whether these characteristics may
influence the outcome of the study.
Internal validity
Correct!
A researcher conducts a quasi-experimental study to determine whether there is
improved weight gain among premature infants who are fed according to cue-
based protocols. The researcher trained neonatal intensive care nurses to apply
cue-based feeding to orally fed infants and notes a statistical difference in weight
gainbetween infants fed according to cue-based protocols and those fed
