Reliability and validity of the Italian version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V).

OBJECTIVES: To evaluate the reliability and validity of the Italian version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). PATIENTS AND METHODS: Eighty dysphonic patients and 120 asymptomatic subjects were enrolled. The voice signal of each participant was recorded, listened to and rated by 3 licensed speech-language pathologists using the GRBAS scale and the Italian version of the CAPE-V. The intra- and interrater reliability of the CAPE-V was assessed as well as the degree of association between the CAPE-V and GRBAS judgments. The CAPE-V values were also compared between the patients with dysphonia and the asymptomatic subjects. RESULTS: The intra- and interrater reliability appeared to be good for all the parameters except for the strain parameter. The attributes 'consistent' and 'intermittent' demonstrated optimal intra- and interrater reliability. The difference between pathological and control groups was significant for six perceptual parameters. The highest average correlation between GRBAS and CAPE-V judgments was found between overall severity and grade while the lowest was found between the two strain scales. CAPE-V profiles differed significantly between different pathological groups. CONCLUSION: The Italian version of CAPE-V appears to be a reliable and valid tool for the perceptual analysis of the voice signal.
