description | OBJECTIVE: Voice serves as an identity and is one of the primary requisites of an individual, especially for singers who are extensive professional voice users with greater vulnerability to voice disorders. The aim of this study is to translate and validate the Tamil version of Voice-Related Quality of Life (T-VRQOL), a self-rating questionnaire that estimates the influence of voice disorders on quality of life. The study also intends to compare the T-VRQOL scores in singers (with and without voice complaint) and non-singers, and to correlate T-VRQOL and the Tamil Singing Voice Handicap Index-10 (TSVHI-10). METHOD: In this cross-sectional study, 120 native Tamil speakers (40 classically trained Carnatic singers without voice complaints, 40 Carnatic singers with voice complaints and 40 normal non-singers) in the age range of 20 to 50 years, filled in the T-VRQOL and the TSVHI-10 rating scales, along with a demographic questionnaire. RESULTS: Reliability of T-VRQOL was established with Cronbach α coefficient (r = 0.9, P < .001) and good test-retest reliability (r = 0.98). The validity of T-VRQOL was confirmed by examining convergent and discriminant validity. T-VRQOL also demonstrated a good correlation with the TSVHI-10 (r = 0.838, P < .001). On comparing the T-VRQOL scores across the groups, singers (13.88 and 24.3) obtained higher values than the non-singers (11.63). Among the singers, those with voice complaints (24.3) scored higher than those without voice complaints (13.88) in the T-VRQOL. CONCLUSIONS: The Tamil version of Voice-Related Quality of Life (VRQOL) questionnaire correlates well with TSVHI-10. It proves to be an effective clinical tool in effectively evaluating the VRQOL among the Tamil-speaking population. |
