STUDY GUIDE 2026/2027
Nurse researchers critiquing research reports should be concerned with the assessment of the
validity and reliability of study instruments: - ANS ✔✔to determine whether the concepts and
variables were measured adequately
An ear temperature probe that consistently reports body temperature at a degree lower than
the patient's actual temperature has what type of reliability or validity problem? - ANS
✔✔reduced reliability, systematic error
A researcher who is developing a new instrument to measure pain has been informed that the
instrument has face validity. The researcher's next step should be to: - ANS ✔✔assess the
content validity of the instrument
Which type of validity is most difficult to establish? - ANS ✔✔construct validity
When the nurse researcher demonstrates that an instrument is highly reliable, which type of
error is reduced? - ANS ✔✔systematic error
The reliability coefficient of a new instrument is established at 0.86. The nurse researcher
should interpret this finding as: - ANS ✔✔low error variance; high reliability
A new instrument has been determined to be highly valid. The nurse researcher should
interpret this finding to mean: - ANS ✔✔it accurately measures level of mentation
Which type of validity is demonstrated when a nurse researcher submits items of an instrument
to a panel of experts to evaluate item clarity? - ANS ✔✔content validity
, Which type of validity is demonstrated by administering a test in which all items relate to
wound care, and then evaluating student performance in caring for patients with wounds in the
clinical setting? - ANS ✔✔Criterion-related validity
Concurrent validity indicates: - ANS ✔✔the degree of correlation of two measures of the same
concept administered at the same time.
What type of validity is demonstrated by examining the extent to which a passing grade in a
nursing course is correlated with passing the registered nurse licensure examination? - ANS
✔✔predictive validity
During development of an instrument to measure self-esteem, the nurse researcher
administered the instrument to individuals who were substance abusers and to individuals who
were not substance abusers and anticipated a significant difference in scores. This method of
establishing construct validity is categorized as what? - ANS ✔✔contrasted-groups approach
A nurse researcher assesses the degree to which individual terms on a scale cluster together
around multiple dimensions using what? - ANS ✔✔factors analysis
A nurse researcher describes an instrument that is administered repeatedly and obtains the
same results as demonstrating: - ANS ✔✔reliability
A nurse researcher describes an instrument that produces the same result when it is
administered to the same subjects under similar conditions on two or more occasions as
possessing: - ANS ✔✔stability
The nurse researcher is interested in estimating how reliably data can be used to generalize the
findings of a study. In order for this to occur, the researcher should use: - ANS ✔✔inferential
statistics
