Beschreibungen/Notizen

• Perceptual evaluation was performed by means of the GRBAS scalefor a series of nine pathological voice samples that were presented twice to a group of 23 judges, consisting of experienced and inexperienced otolaryngologists (ENTs) and speech-language pathologists (S/LPs). The time interval between ratings was 14 days. Test-retest reliability was moderate. The best agreement between the observers was obtained for the G (grade) parameter and the worst for the S (strained) parameter. Considering the medians of the GRBAS ratings, no significant influence was measured for level of experience or professional background. Yet, based on means, the results show that professional background has a greater impact on perceptual rating than experience.
