Overview

Introduction: Assessing quality of life is part of a comprehensive assessment of voice. The aim of this study is to adapt the original version of Voice Handicap Index to Slovak language, to analyze the impact of age and gender on the score in the VHI-30 questionnaire and its shortened version, VHI-10, and to create degrees of impaired quality of life according to the score.

Material and Methods: Fifty-two patients with voice disorder and one hundred and four participants without voice disorder were enrolled. Each participant of study completed a VHI-30 questionnaire. The effect of age on the score was evaluated by calculating the Spearman coefficient. Data from healthy respondents over the age range of 20 to 60 years were used. The impact of gender on patient scores was evaluated using the Wilcoxon test. By calculating percentile values, the degrees of impact of voice disorder on quality of life were defined.

Results: Statistical analysis showed a non-significant effect of age on scores in the VHI--30 (ρ = 0.04; p = 0.68) and VHI-10 questionnaires (ρ = 0.33; p = 0.74). It indicates that age has no significant impact on VHI scores. There are no statistically significant differences in total scores of VHI-30 (W = 1 282; p = 0.64) and VHI-10 (W = 1 328.5; p = 0.87) between the genders. The degree of impairment of quality of life can be determined as acceptable, mild, moderate or severe according to the scores in the questionnaires.

Conclusion: Age and gender have non-significant effect on scores in the VHI-30 and VHI-10 questionnaires.
