A measure of which of the following traits would be a particularly good candidate for a test-retest reliability assessment?
A) Anxiety
B) Fear of heights
C) Mood
D) Fatigue
B
Feedback:
The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test–retest procedures. Attitudes, mood, and so forth can be changed by experiences between two measurements. Thus, stability indexes are most appropriate for fairly enduring characteristics, such as temperament or fear of heights. Anxiety, mood, and fatigue are not fairly enduring characteristics.
