“…Although it can be used as a stand-alone questionnaire, we use the HNC-PCI with the University of Washington Quality of Life questionnaire, version 4 (UWQoL), 13 which is a validated HNC-specific health-related QoL (HRQoL) tool that contains 12 domains scaled from 0 (worst) to 100 (best) according to the hierarchy of response.

Physical function is the simple mean score of the swallowing, chewing, speech, saliva, taste, and appearance domains.…”
