Brief summary

The aim of the study is to translate and culturally adapt the Turkish version of the EASE (EASE-TR) scale and investigate its validity and reliability.

Detailed description

The study consists of two phases. In the first phase of the study, the scale will be translated and culturally adapted into Turkish. The second phase involves assessing participants and validating the translated scale. In this phase, participants will complete the EASE-TR and the severity part of the Vocal Tract Discomfort Scale (VTDS) before and after a 1-hour performance. One hundred choir member between the ages of 18 and 65 will be included in the study. Both construct and criterion validity procedures will be used.Within the scope of construct validity, the Known Groups Validity method will be used based on variables such as experience duration, vocal training status, and the presence or absence of current vocal complaints. A comparison of pre- and post-performance EASE-TR scores will be conducted. Regarding criterion validity, the correlation between EASE scores and the severity part of the VTDS will be examined. For reliability, Cronbach's alpha and test-retest reliability will be calculated. The questionnaire will be administered a second time to 30 participants after 14 days in order to measure test-retest reliability.
