Abstract: The aim of the present study was to adapt and validate the English version of pediatric voice handicap index (pVHI) into Malayalam language. The English version of pediatric voice handicap index was translated into Malayalam language using parallel back translation. The translated version was content validated by three qualified speech language pathologists. The content familiarity was carried out by 10 parents of children with voice problems. This was distributed to 136 parents (57 parents of children with dysphonia, 79 parents of children with no voice problems). The internal consistency and test--retest reliability was determined using Cronbach's alpha and intraclass correlation coefficient. Independent s le t-test was used to assess the difference in means. Kappa coefficient was used to determine the correlation between overall severity of the problem and total pVHI. Discriminant analysis was used to identify thresholds for differentiating between normal and dysphonic participants. The results obtained revealed that the Malayalam version of pVHI has an excellent internal consistency total (α=0.974), functional (α=0.922), physical (α=0.953), and emotional (α=0.923). There was an excellent test-retest reliability total (r=0.937), functional (r=0.954), physical (r=0.95), and emotional (r=0.929). The prediction probability of the dysphonics is 98.2% using the discriminant score function. The translated and validated pVHI tool can be effectively used in the assessment of children with voice problems. It can provide a better insight into the parents' perception of their child's voice problems.

Abstract: Yakshagana, a popular traditional folk art from Karnataka, India, includes singing and dancing. Yakshagana singer or Bhagavata plays an important role in singing and conducting the performance. The present study aims to assess the singing vocal health using Singing Voice Handicap Index-10 (SVHI-10) in these singers and to compare between those who report voice problem and those who do not. A cross-sectional study was carried out on 26 Bhagavata using demographic questionnaire and SVHI-10 in the Kannada language. Descriptive statistics was used to summarize the data. Independent s le t test was used to compare the responses for demographic variables between the two groups of singers with and without voice problems. The difference in scores of SVHI-10 between the two groups was analyzed using Pearson's chi-square test. Of the Bhagavata, 38% reported to have experienced voice problems, which affected their singing, with higher total SVHI-10 score (31.2 ± 5.7) compared with those who did not report any problems (16.81 ± 9.56). A statistically significant difference between the groups was noted in the emotional domain and total scores. The present study provides preliminary information on the voice handicap reported by Bhagavata. The singers reporting voice problems scored higher on SVHI-10. A healthy singing voice is essential for Yakshagana singers, and voice problems can have a significant impact on their performance and livelihood. Hence, results of the present study indicate the need to understand these singers' voice problems and their impact more comprehensively, and educate them about voice care.

Abstract: Voice problems are commonly reported by professionals in occupations involving a large amount of voice loading. The aim of the present study was to investigate the prevalence of voice problems in Mar Thoma priests and identify possible risk factors responsible for voice problems. This is a cross-sectional study. The study group consisted of 270 Mar Thoma priests with 1-35 years of professional experience. A self-reported questionnaire was used to collect the data. Mar Thoma priests were found to have higher career (47.8%) and year prevalence (25.2%) of voice problems with 17.8% of them reporting frequent voice problems during their career. Asthma, allergy and frequent throat clearing behavior were found to have significant association with priests reporting frequent voice problems. Significantly higher number of priests with frequent voice problems missed their work. The study results provide valuable preliminary information regarding the prevalence voice problems and associated risk factors in Mar Thoma priests. However, further investigations are required for in-depth understanding of the types of voice problems these priests experience and their impact on their quality of life.
