title: Establishing validity of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V).
abstract: OBJECTIVE
  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.
  
  
  METHODS
  The validity of the CAPE-V was 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.
