Evaluation of the Correlation Between Turkish Voice Handicap Index-10 and Turkish Voice-Related Quality of Life Scale.

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.
