Which of the following scales is most sensitive to differences between ratings?
a. A visual analogue scale
b. 0- to 10-numerical rating scale
c. Five-item verbal descriptor scale
d. Seven-item Likert scale
ANS: A
A ruler is used to precisely measure the distance between the end point of the analogue scale and the subject's mark on the 100-mm line.
A 0- to 10-numerical rating scale will allow for more variability than a five-point scale, but still offers limited choices.
A five-item scale will not generate a lot of variability. A ruler is used to precisely measure the distance between the end point of the analogue scale and the subject's mark on the 100-mm line.
A seven-item scale will provide more variability than a five-item scale; however, a visual analogue scale will be measured using a ruler. This measurement is more precise.
