| Summary: | The Evaluation of the Ability to Sing Easily (EASE) is used to assess the singer's perceptions of the current singing voice status. The purpose of this research was to culturally adapt the Turkish version of the EASE (EASE-TR) and investigate its validity and reliability.OBJECTIVESThe Evaluation of the Ability to Sing Easily (EASE) is used to assess the singer's perceptions of the current singing voice status. The purpose of this research was to culturally adapt the Turkish version of the EASE (EASE-TR) and investigate its validity and reliability.According to the Professional Society for Health Economics and Outcomes Research recommendations, the original version of the EASE was translated and culturally adapted into Turkish. One hundred amateur or professional choir members completed the EASE-TR and the Vocal Tract Discomfort Scale (VTDS) before and after the singing performance. EASE-TR scores before and after performance were compared for construct validity. "Known Groups Validity" was used according to variables of singing experience, voice training status, and current voice complaints. As part of the criterion validity assessment, the correlation between the after-performance EASE-TR scores and the VTDS scores was evaluated. Cronbach's alpha was calculated for internal consistency. EASE-TR was applied twice to 35 participants to measure test-retest reliability.METHODSAccording to the Professional Society for Health Economics and Outcomes Research recommendations, the original version of the EASE was translated and culturally adapted into Turkish.

As part of the criterion validity assessment, the correlation between the after-performance EASE-TR scores and the VTDS scores was evaluated. Cronbach's alpha was calculated for internal consistency. EASE-TR was applied twice to 35 participants to measure test-retest reliability.Statistically significant (P < 0.001) differences were found between the before and after performance scores in all subscales and the total score of the EASE-TR. A moderate positive correlation (r = 0.664) was observed between EASE-TR and VTDS. There was a significant difference in the EASE-TR scores between the group with vocal complaints and the group without complaints. The Cronbach alpha value of the EASE-TR was found to be 0.894. EASE-TR was found to have a good degree of test-retest reliability.RESULTSStatistically significant (P < 0.001) differences were found between the before and after performance scores in all subscales and the total score of the EASE-TR.

Our findings indicate that EASE-TR is a sensitive tool that can measure the positive effect of voice training, experience, and vocal warm-up and even can detect voice complaints in participants who are not actively seeking treatment.CONCLUSIONEASE-TR is a valid and reliable self-reported tool for singers to measure current singing voice function.
