| Summary: | Auditory-perceptual rating of voice is one of the compulsory clinical voice
evaluations. One tool that has gained attention for this purpose is the Consensus
Auditory-Perceptual Evaluation of Voice (CAPE-V). The CAPE-V has been reported
to have a more standardized approach in evaluating the voice. Because of its
advantages, the CAPE-V has been adapted in several languages to suit specific
populations. Accordingly, the adaptation of the CAPE-V into Malay is essential for its
utility among the Malaysian population, which this study aims to achieve. This crosssectional
study involves translating the CAPE-V into Malay, followed by establishing
the validity and reliability of the translated CAPE-V. The translation processes (i.e.,
forward and backward) involved 4 translators with at least 14 years of experience.
Most items were similarly translated by the translators, except for a few, which were
subsequently accepted as similar, following consensus among the translators. The
content validity analysis involved 2 raters, with at least 12 years of clinical experience,
using the CVI method. The CVI value was above the acceptable level, thus, all items
were retained. For the analyses of construct validity, concurrent validity, inter-rater
reliability, and intra-rater reliability, the translated CAPE-V, termed the Malay CAPEV,
was used to rate the voice samples recorded from 38 participants, which consisted
of 19 individuals with normal voices (6 males and 13 females) and 19 individuals with
voice disorders (8 males and 11 females). The ratings were performed by 3 raters with
at least 12 years of clinical experience. The construct validity was examined by using the known-group method involving a comparison of the scores of each vocal parameter
of the Malay CAPE-V of the normal and disordered voice groups using the Mann-
Whitney U test, which indicated a statistically significant difference between the two
groups. For the concurrent validity, the relationship between the scores of each vocal
parameter of the Malay CAPE-V and GRBAS Scale were examined using the
Spearman correlation, which indicated a statistically significant very strong positive
correlation between the two tools. For the inter-rater reliability and intra-rater
reliability, the ICC values of the scores of each vocal parameter of the Malay CAPEV
were all above the acceptable level. Therefore, the Malay CAPE-V is a valid and
reliable tool for an auditory-perceptual rating of voice among the Malaysian
population. |
