Abstract

Singers' self-reporting of their voice problems can be helpful in the treatment of voice disorders by speech-language pathologists (SLP), which requires a valid questionnaire. This study was conducted to translate and validate the Singing Voice Handicap Index-10 (SVHI-10) questionnaire in the Persian language. This cross-sectional study was conducted in two main steps (1) translation of the questionnaire and determination of face and content validity and (2) survey of singers. The questionnaire was first translated by a SLP who was an expert in voice disorder and also proficient in the English language. The face and content validity of the questionnaire was confirmed by experts through impact score, content validity ratio, and content validity index. Then it was translated into English and adapted to its original version. A valid questionnaire was given to 70 singers to determine their ability to distinguish singers with voice problems from healthy singers and their internal consistency. The face and content validity of the questionnaire was confirmed without excluding any item. The results showed that the questionnaire has excellent internal consistency (α=0.930). With the optimal cut-off point of 14.5, this questionnaire was able to identify singers with voice problems with 90% accuracy. Also, the sensitivity and specificity were 84.85% and 94.59%, respectively. Also, the area under the Receiver Operating Characteristic (ROC) curve was equal to 0.937. The results revealed that the Persian version of SVHI-10 is a reliable and valid instrument to identify singers with voice problems, so it can be used by SLPs.
