The reliability and validity of patient self-rating of their own voice quality

According to Lee et al. patients appear to have good validity and consistency using GRBAS as a self-perception tool. This tool is used among clinicians to subjectively assess the general and partial quality of voice. Although, consistent among themselves, patients do not have an agreement with clinicians. Patients and clinicians have an inter-rater agreement no better than chance and they rated consistently more severely than clinicians. Full text: Lee M, et al.
