Consensus Auditory Perceptual Evaluation of Voice (CAPE-V): Systematic Review of Methods Used for Adaptation and Validation Consensus Auditory Perceptual Evaluation of Voice (CAPE-V): revisión sistemática de los métodos utilizados para su adaptación y validación

Abstract

Introduction. CAPE-V is widely used for vocal perceptual evaluation and has been adapted and validated in multiple languages. Through an exhaustive analysis, this study sought to advance in establishing a standard in the method used in its adaptation and validation.

Objective. To review articles published between 2002 and 2022 that have adapted and validated CAPE-V in different languages, to thoroughly evaluate the adaptation, methodology, and statistics used.

Methods. A systematic review was conducted using Scopus, Google Scholar and PubMed to identify articles that adapted and/or validated CAPE-V between 2002 and 2022. The title and summary were analyzed to pre-select the sample. To evaluate the risk of bias of the included studies, the full text was critically analyzed.

Results. The initial search identified 568 items. When duplicates were removed, 559 were reviewed and 23 were pre-selected. 12 were finally included and analyzed considering adaptation, methodology, and statistical analysis. The results show that the adaptation and validation of CAPE-V to different languages is essential to ensure accurate and reliable measurements in different populations.

Analysis and discussion. There is heterogeneity in how CAPE-V is adapted and validated. However, all studies were successful in producing valid results, underlining the importance of these processes for clinical practice.

Conclusions. Adaptations and validations of CAPE-V were performed heterogeneously due to the absence of a standard protocol. It is necessary to generate guidelines to perform these processes by providing this scale to the clinic, ensuring quality and reliability of results.
