Translation, Validity, and Reliability of Singing Voice Handicap Index in Persian Traditional Singers: A New Revised Version

The mean P-SVHI score, range 0 -100, in healthy singers in the current study (16.9) also is similar to the results previously reported by (15), and Turkish (pathology group vs. healthy group: 53.6 ± 28.9 vs. 21.8 ± 18.5) (11). Also, the P-SVHI score (0 -100) for dysphonic subjects in our study was 40.9, which is more than the results for an Italian version in which dysphonic signers scored 31.68 (converted to 0-100), suggesting that voice disorder in our traditional singers is more than that in other style singers.…”

“…The SVHI has been translated into various languages (3,(8)(9)(10)(11)(12)(13)(14)(15)(16). The validation of the P-SVHI was previously investigated by Ghaemi et al (15) in all singing styles.…”

Normative values for singing voice handicap index – systematic review and meta-analysis

Adaptation and validation of the Italian Singing Voice Handicap Index-10 (SVHI-10-IT)

“…Cronbach’s alpha was used to assess internal consistency with values above 0.7 indicating desirable levels. The Cronbach’s alpha cut-off were: 0.7 ≤ α < 0.8, Acceptable; 0.8 ≤ α < 0.9, Good; 0.9 ≤ α, Excellent 23 . Additionally, to investigate the psychometric properties of the items, inter-item association and Cronbach’s alpha with deleted items were also computed.…”
