- Abstract
Purpose: The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was developed to provide a protocol and form for clinicians to use when assessing the voice quality of adults with voice disorders (Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kramer, & Hillman, 2009). This study examined the reliability and the empirical validity of the CAPE-V when used by experienced voice clinicians judging normal and disordered voices. Method: The validity of the CAPE-Vwas examined in 2 ways. First, we compared judgments made by 21 raters of 22 normal and 37 disordered voices using the CAPE-V and the GRBAS (grade, roughness, breathiness, asthenia, strain; see Hirano, 1981) scales. Second, we compared our raters' judgments of overall severity to a priori consensus judgments of severity for the 59 voices. Results: Intrarater reliability coefficients for the CAPE-V ranged from .82 for breathiness to .35 for strain; interrater reliability ranged from .76 for overall severity to .28 for pitch. Conclusions: Although both CAPE-V and GRBAS reliability coefficients varied across raters and parameters, this study reports slightly improved rater reliability using the CAPE-V to make perceptual judgments of voice quality in comparison to the GRBAS scale. The results provide evidence for the empirical (concurrent) validity of the CAPE-V.
