Correlation Between the Voice Handicap Index and the Multidimensional Voice Program

Objective: Voice disorders have an adverse effect on the psychological, social, and physical lives of patients, and they diminish their quality of life. A subjective self-assessment tool, the voice handicap index (VHI-10) and an objective diagnostic tool, the multi-dimensional voice program (MDVP), are frequently used in the evaluation of voice disorders. The aim of this study is to determine how these tools correlate with each other and whether they can be used independently.Methods: A total of 27 patients were enrolled in this study. VHI-10 and MDVP were prepared to perform voice analysis. The strength of the linear relationship was measured using Pearson's and Spearman's correlation.Results: The study included 14 (51.8%) males and 13 (49.2%) females with a mean age of 46.07 +/- 14.78 years. The total score of the VHI-10 was 23.4 +/- 9.9. According to the MDVP scores, the mean fundamental frequency (mF0) was 188.064 +/- 53.6 Hz (88.946-260.153), jitter (percentage jitter) was 1.85 (1.115-7.27), shimmer (absolute shimmer) was 0.475 (0.394-0.829), and noise harmonic ratio (NHR) was 1.715 +/- 4.7. There was no correlation between VHI scores and MDVP parameters, including mean fundamental frequency, jitter, shimmer, and NHR (r=0.086;-0.018; 0.002; and 0.083) (p>0.05).Conclusion: VHI-10 scores and parameters of the MDVP were not significantly related to each other, and these tools cannot be used interchangeably.
