Testing of a new instrument demonstrates that it has a high degree of internal consistency. What does this indicate to the nurse researcher?
 
  a. The instrument is appropriate to use to measure a single concept.
  b. The instrument has low measurement error and high error variance.
  c. More refinement of the instrument is necessary before it can be applied.
  d. The instrument is valid, but the reliability has yet to be determined.

Question 2

In testing an instrument consisting of 25 items for homogeneity using the item-to-total correlation, 8 items were found to have a low correlation to the total.
 
  The nurse researcher interprets this information to mean that the researcher should do what?
  a. Use the instrument without changes.
  b. Use the instrument only with a multitrait-multimethod approach.
  c. Retain the 8 items with low correlation and delete the other 17 items.
  d. Delete the 8 items with low correlation and retain the other 17 items.

Answer to Question 1

ANS: A

Feedback
A Internal consistency or homogeneity reliability indicates that the items within the scale measure the same concept.
B This is an inaccurate statement.
C A high degree of internal consistency indicates that the instrument is refined; however, additional testing is always warranted.
D There is no indication that the instrument is valid; the reliability coefficient is very acceptable.

Answer to Question 2

ANS: D

Feedback
A The instrument should be modified. Items should be deleted.
B The multitrait-multimethod approach is appropriate for ongoing instrument development and validity.
C The reverse of this answer should be performed: 17 items should be retained and 8 items should be eliminated.
D Eight items should be deleted and 17 items should be retained.
