Faces Scale
The Faces Scale has been used for evaluating emotional responses to pain in children 3-17 years old. It is a 1-page form with 9 faces in order from “happy” to “upset” with numerical values given to each face. The order of the faces was consistently affirmed by 200 children over 5 years regardless of age, gender, or health status, and the tool has been integrated as a routine measure for management of acute, recurrent, and chronic pain.26,38 Although this scale has been used for emotional response to pain, in this study it was also considered an appropriate measure for children’s emotional response to discomfort and anxiety in the cancer center.
