Validation of the Italian version of the Singing Voice Handicap Index

Abstract

Singers constitute a specific population that is particularly sensitive to vocal disability, which may have a higher impact on their quality of life compared to non-singers. A specific questionnaire, the Singing Voice Handicap Index (SVHI), was created and validated aimed to measure the physical, social, emotional and economic impacts of voice problems on the lives of singers. The aim of this study was to validate the Italian version of the SVHI. The validated English version of the SVHI was translated into Italian and then discussed with several voice care professionals. The Italian version of the SVHI was administered to 214 consecutive singers (91 males and 123 females, mean age: 32.62 ± 10.85). Voice problem complaints were expressed by 97 of the singers, while 117 were healthy and had no voice conditions. All subjects underwent a phoniatric consultation with videolaryngostroboscopy to ascertain the condition of the vocal folds. Internal consistency of the Italian version of the SVHI showed a Cronbach's α of 0.97. The test-retest reliability was assessed by comparing the responses obtained by all subjects in two different administrations of the questionnaire; the difference was not significant (p = ns). The SVHI scores in healthy singers was significantly lower than the one obtained in the group of singers with a vocal fold abnormality (29.26 ± 25.72 and 45.62 ± 27.95, p < 0.001, respectively). The Italian version of the SVHI was successfully validated as an instrument with proper internal consistency and reliability. It is a suitable instrument for the self-evaluation of handicaps related to voice problems in the context of singing.

Validation and reliability of Turkish Singing Voice Handicap index

“…Likert tipi yani sıralanabilir yanıtlar içeren bir ölçekte olabildiğince 1'e yakın olmalıdır ve güvenirliği yüksek olan anketlerde 0.7'nin üzerinde olması beklenir. [6] Bu çalışmada T-ŞSHE ölçeği, grup 1 için 0.917 ve grup 2 [7] çalışmasıyla benzerlik göstermektedir. Şan sesi sorunu olan grupta saptanan patolojilerin dağılımı literatürde belirtilen ile uyumlu bulundu.…”

Translation and Validation of Tamil Version of Singing Voice Handicap Index-10 (TSVHI-10)

“…The clinical outcome measures obtained would be more reliable with the translated instruments because it not only ensures that the information investigated would be better understood by the individual, but would also confirm that the responses are certain, since the individuals have responded in their native language. Hence from its original version in English by Cohen et al, 6 the singing voice handicap index has been translated and validated in various languages, such as Korean, 11 Italian, 12 Polish, 13 and Indian language-Kannada. 14 However, there are limited studies carried out with regards to self-perception of voice among the trained South-Indian singers.…”

Análise do índice de desvantagem vocal para o canto de coristas idosos

“…O escore também foi semelhante ao valor normativo médio de um grupo de 729 cantores profissionais saudáveis com idade entre 18 e 64 anos, publicado em uma revisão sistemática recente, que apresentaram um IDV-C de 20,35 com intervalo de confiança entre 10.6 e 30.1 (15) . Estudos que validaram o protocolo em diversos idiomas demonstraram que é um método válido e confiável na identificação da autopercepção do indivíduo em relação ao impacto dos problemas vocais no canto (16)(17)(18)(19)(20)(21) .…”
