Abstract
To develop the cultural and linguistic adaptation of the Brazilian version of the Adapted Borg CR10 for Vocal Effort Ratings. The instrument Adapted Borg CR10 for Vocal Effort Ratings was translated into Portuguese by two Brazilian bilingual speech-language pathologists, whose translations were compiled into one version. Back-translation into English was performed by a third bilingual Brazilian speech-language pathologist who did not participate in the previous stages. After translation and back-translation, the items of the translated version were compared with the original instrument and discrepancies were modified by consensus of a committee composed of three speech-language pathologists, resulting in the version translated into Brazilian Portuguese entitled Escala Borg CR10-BR adaptada para esforço vocal. For cultural equivalence of the Portuguese version, the option "not applicable" was added to the categorical scale and 15 individuals with dysphonia, with otorhinolaryngological medical diagnosis, responded to the Escala Borg CR10-BR adaptada para esforço vocal after reading the perceptual-auditory evaluation protocol CAPE-V phrases. During the process of translation and cultural adaptation, no item was changed and/or eliminated from the questions. The Escala Borg CR10-BR adaptada para esforço vocal kept the same structure as the original, with a scale ranging from 0 to 10, with 0 being "no vocal effort at all" and 10 being "maximum vocal effort". The Brazilian version of the Adapted Borg CR10 for Vocal Effort Ratings, entitled Escala Borg CR10-BR adaptada para esforço vocal, presents cultural and linguistic equivalence to the original instrument.
Highlights
Voice production depends on several factors, including the balance between the aerodynamic and myoelastic forces of the larynx, in addition to the phonatory system[1]
A healthy voice should be produced in an effective manner, without effort, and sound interesting and clear in order to retain the attention of the listener[2]
Voice self-assessment protocols are valuable in clinical practice, as they help patients to understand and perceive the impact of dysphonia in their life, improving adherence to treatment
Summary
Voice production depends on several factors, including the balance between the aerodynamic and myoelastic forces of the larynx, in addition to the phonatory system[1]. A healthy voice should be produced in an effective manner, without effort, and sound interesting and clear in order to retain the attention of the listener[2]. When muscular harmony is maintained, listeners hear a so-called good quality sound produced without difficulty or discomfort on the part of the speaker[1]. Some aspects may influence vocal production and entail greater vocal effort, such as: competing sounds, the individual’s need to project their voice into the distance, the presence of a vocal or larynx disorder, or excessive voice use[3]. When vocal effort becomes chronic or excessive, speakers may experience discomfort, which hinders communication performance and leads them to seek professional treatment[4]. Measuring vocal effort requires analysis of the clinical evaluation data as well as individuals’ reported perception
