Índices acústicos multiparamétricos na avaliação de indivíduos disfônicos e não disfônicos

Abstract

Introduction: Currently there is a gradual growth of interest in acoustic analysis with multiparametric approaches. This analysis demonstrates a strong relationship with the auditory-perceptual assessment and great reliability in the detection of dysphonia. However, the multiparametric acoustic indexes (MAI) follow different forms of proposition and validation. Thus, it becomes necessary to understand the different steps taken to validate the MAI, and based on this, propose a manual for the construction and validation of the MAI. Objectives: Map, describe and analyze the phases and steps taken during the construction and validation of MAI; to present a manual of recommendations for the creation and validation of multiparametric acoustic indices used in vocal acoustic evaluation. Methodology: This dissertation was divided into two studies. 1) The first is a scope review whose PCC was P - individuals with and without vocal problems C - construction and validation of MAI and C - voice area. An electronic search was carried out in Pubmed/Medline, LILACS/BVS, Scopus, Web of Science, EMBASE and Cochrane Library, ClinicalTrials, ASHA Wire, Brazilian Digital Library of Theses and Dissertations and ProQuest. Data on the phases and stages of AMI validation were extracted. The analysis was carried out descriptively. 2) Data about the first steps and phases that must be carried out during the construction and validation phase of the MAI were analyzed after reviewing the scope and crossed with methodologies described by associations and researchers in the field of test validation. Results: 1) Studies on the construction and validation of MAI were published between 2000 and 2022, mostly studying the AVQI and the DSI. 98 studies were classified in the scale evaluation phase and 86 in the validity tests phase, with accuracy tests, ROC curve and likelihood ratio calculation being widely used. 2) The recommendations for creating and validating IAMs were compiled in a manual. Conclusion: The processes for constructing and validating AMIs are diverse and there is no consensus among authors regarding which of these phases are essential. The creation of a guideline with step-by-step instructions on how to create and validate an MAI will facilitate the reproducibility of future studies in the area.
