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.
One-year results in this large cohort of patients with glottal incompetence treated with CaHA vocal fold injection demonstrate that excellent clinical results were achieved.
Injection and medialization laryngoplasty were comparable in their improvement of subjective and objective voice outcomes. Both treatment modalities should be included in the otolaryngologist's armamentarium for managing unilateral vocal fold paralysis.
Purpose: The purpose of this study was to investigate the utility of telepractice for delivering flow phonation exercises to persons with primary muscle tension dysphonia (MTD). Method: Fourteen participants with a diagnosis of primary MTD participated, 7 on site and 7 at remote locations. Each participant received 12 treatment sessions across 6 weeks. Treatment consisted of flow phonation voice therapy exercises. Auditory-perceptual, acoustic, aerodynamic, and quality-of-life measures were taken before and after treatment. Results: Perceptual and qualityof-life measures were significantly better posttreatment and were statistically equivalent across groups. Acoustic and aerodynamic measures improved in both groups, but changes did not reach statistical significance. Results for the 2 service delivery groups were comparable, with no significant differences observed for perceptual and quality-of-life measures. Conclusions: Although the American Speech-Language-Hearing Association supports the use of telepractice for speech-language pathology services, evidence for the use of telepractice for providing behavioral treatment to patients with MTD has been lacking. The results of this study indicate that flow phonation exercises can be successfully used for patients with MTD using telepractice.
Listeners rated the nasality of synthesized vowels using two psychophysical scaling methods (equal-appearing interval scaling and direct magnitude estimation). A curvilinear relationship between equal-appearing interval ratings and direct magnitude estimations of nasality indicated that nasality is a prothetic rather than metathetic dimension. It also was shown that the use of direct magnitude estimation results in nasality ratings that are more consistent and reliable. The results of this experiment are discussed in relation to other studies that have examined the validity and reliability of equal-appearing interval scaling of voice quality. Additionally, there is a discussion of methodological issues for future research and the implications of the findings for clinical and research purposes.
In the demand for standardization of tinnitus assessment tools, developers and clinicians should consider readability as another testable construct, as poor readability may affect both validity and reliability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
