Validity and rater reliability of Persian version of the Consensus Auditory Perceptual Evaluation of Voice

Abstract

Background and Aim: Auditory-perceptual assessment of voice a main approach in the diagnosis and therapy improvement of voice disorders. Despite, there are few Iranian studies about auditory-perceptual assessment of voice. The aim of present study was development and determination of validity and rater reliability of Persian version of the Consensus Auditory Perceptual Evaluation of Voice (CAPE-V).
Methods: The qualitative content validity was detected by collecting 10 questionnaires from 9 experienced speech and language pathologists and a linguist. For reliability purposes, the voice samples of 40 dysphonic (neurogenic, functional with and without laryngeal lesions) adults (20-45 years of age) and 10 normal healthy speakers were recorded. The samples included sustain of vowels and reading the 6 sentences of Persian version of the consensus auditory perceptual evaluation of voice called the ATSHA.
Results: The qualitative content validity was proved for developed Persian version of the consensus auditory perceptual evaluation of voice. Cronbach’s alpha was high (0.95). Intra-rater reliability coefficients ranged from 0.86 for overall severity to 0.42 for pitch; inter-rater reliability ranged from 0.85 for overall severity to 0.32 for pitch (p<0.05).
Conclusion: The ATSHA can be used as a valid and reliable Persian scale for auditory perceptual assessment of voice in adults.
