Summary
Objectives
The aim of this study was to develop the Lithuanian version of the Pediatric Voice
Handicap Index (pVHI) and to assess its psychometric characteristics.
Methods
The Lithuanian version of the pVHI was prepared according to the standard requirements
for the questionnaire translation and adaptation procedure. It also included forward
and backward translations of the original questionnaire, as well as a committee review
and psychometric testing of the final version of the pVHI. A total of 126 children
between 4 and 13 years of age were included in the study. Two study groups were formed:
a group consisting of children with dysphonia (n = 70) and a control group of children
without any alterations in their voice (n = 56). The questionnaire was always completed
by their parents. The results were statistically analysed to assess the reliability,
validity, sensitivity and specificity of the Lithuanian version of the pVHI.
Results
High internal consistency of the Lithuanian version of the pVHI was determined (Cronbach's
α = 0.938). The test-retest analysis also showed a high correlation between the two
tests (r = 0.949) for both the dysphonic and control groups. The mean overall pVHI
score was significantly higher (P < 0.001) in the dysphonic group than in the control group: 26.16 ± 11.84 and 2.43
± 2.61, respectively. Similar results were obtained for all domains of pVHI. The most
sensitive and specific limiting value for discrimination between the clinical and
control groups was the sum of 8 points.
Conclusions
The Lithuanian version of the pVHI is a reliable and valid instrument for the evaluation
of the Voice Handicap Index in the pediatric population and can be easily applied
in daily clinical practice.
