Resumen
SANCHEZ, Martha Peña y DELPRADO-AGUIRRE, Fernando. Surveying Colombian Speech-Language Pathologists on their Reported Training & Practices of Auditory-Perceptual Evaluation of Voice. Rev. Investig. Innov. Cienc. Salud [online]. 2024, vol.6, n.1, pp.148-168. Epub 23-Ene-2024. ISSN 2665-2056. https://doi.org/10.46634/riics.238.
Objective:
To explore the training and use of auditory perceptual evaluation of the voice reported by Colombian speech-language pathologists.
Study Design:
Cross-sectional observational research with a quantitative approach.
Methods:
A digital questionnaire was designed and distributed to gather information regarding professionals' training process and implementation of auditory-perceptual evaluation procedures. Descriptive statistics were applied, and several generalized linear models were adjusted to determine the influence of certain variables on others.
Results:
The survey received responses from 40 speech-language pathologists, revealing that the most used scales for training and evaluating vocal quality within this group are direct magnitude estimations (82.5% and 77.5%). Similarly, in this group, the tasks most frequently used to train and use as an evaluation strategy are vowel assessments (38%) followed by spontaneous speech (30%). Practitioners of this group were mostly trained using a conceptual framework involving multiple exposures to rating (42.5%). The use of direct magnitude estimation in training with a normal voice showed significance (p = 0.015), as did the use of the vowel /i/ in training with an equal-appearing interval (p = 0.013). The statistical models relating the scale used to the scale on which participants were trained were also significant (p < 0.05).
Conclusions:
The GRBAS scale is the training tool most used by the group of speech-language pathologists of the study group in Colombia. Future efforts should focus on improving training practices for auditory-perceptual evaluation, exploring alternative conceptual frameworks, and incorporating external references to enhance validity and reliability.
