Voice Activity and Participation Profile

The VAPP is a self-assessment questionnaire that gives insights into the ways activities and participation are limited in clients with dysphonia. This measure of voice-related quality of life has been widely translated and used clinically. The VAPP was developed by Dr Estella P-M Ma and Professor Edwin M-L Yiu in the Division of Speech and Hearing Sciences.
