Abstract

Reliability of the GRBAS tool for perceptual evaluation of paediatric voice disorder is measured in this study of children with a history of laryngotracheal reconstruction surgery (LTR). Additionally, the relationship between parent proxy/child self-report of voice related quality of life with clinician perceptual rating of voice quality is analysed. Eleven children with a history of LTR provided voice recordings following the stimuli set by the CAPE-V protocol. Subjective impact of voice quality on life was measured using the Pediatric Voice-Related Quality of Life Questionnaire. Four trained judges rated the sound files according to both the GRBAS and CAPE-V protocol. Intraclass correlation coefficients were high for both intrarater and interrater judgements across all parameters of the GRBAS protocol, and a strong correlation was found between the Grade rating of the GRBAS and the Overall Severity rating of the CAPE-V. Some elements of parent proxy reporting of VRQOL were significantly negatively correlated with clinician perceptual rating of voice quality, while there was no significant relationship between child self-report and clinician perceptual rating.
