Abstract
OBJECTIVE: Aim of this sudy was to evaluate the correlation between Turkish Voice Handicap Index-10 (TVHİ-10) and Turkish Voice-Related Quality of Life Questionnaries (TV-RQOL) on patients with dysphonia. METHODS: Two different groups were formed with patients with dysphonia and healthy individuals between February and July 2016. After medical history and otorhinolaringologic and phoniatric examinations all the subjects completed TVHI-10 and TV-RQOL questionnaries. The correlation between scores of parameters of questionnaries were evaluated. RESULTS: Data of 104 patients (59 women, 45 men) with a mean age of 46±15 years in dysphonia group and 75 individuals (38 women, 37 men) with a mean age of 45±13.8 years in healthy group were evaluated. TVHI-10 and TV-RQOL parameters' scores were significantly higher in dysphonia group than healthy group. There were positive and significant correlations between scores of TVHI-10 and TV-RQOL parameters of all 179 individuals. There was significant positive correlation between total scores of TVHI-10 and TV-RQOL values of all individuals (r=0.949, p<0.001). CONCLUSION: There is positive significant correlation between validated Turkish versions of VHI-10 and V-RQOL questionnaries as a self-assessment measurement tools. The results of studies which use TV-RQOL can be compared with the results of the studies using TVHI-10.
