Abstract
This methodological study aimed to assess the validity and reliability of the Turkish version of the Evaluation of the Impact of Hearing Loss in Adults (ERSA) questionnaire for individuals with treated hearing loss. The study involved 200 participants, and both exploratory factor analysis and confirmatory factor analysis were used to examine structural validity. External validity was assessed by correlating ERSA scores with the Abbreviated Profile of Hearing Aid Benefit (APHAB). Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and the intraclass correlation coefficient, respectively. The Turkish ERSA demonstrated strong psychometric properties, with significant correlations between APHAB and ERSA scores and excellent internal consistency and test-retest reliability. The findings suggest that the Turkish ERSA is a valid and reliable tool for evaluating the impact of hearing loss in individuals.
