Psychometric Properties of the Turkish Social Participation Restrictions Questionnaire (SPaRQ-T) for Adults With Hearing Loss: A Rasch Analysis

This study aimed to adapt the Social Participation Restrictions Questionnaire (SPaRQ) into Turkish (SPaRQ-T) and assess its validity and reliability for evaluating participation restrictions in adults with hearing loss. A cross-sectional, multicenter study was conducted with 278 individuals with hearing loss who had used hearing aids for at least one year. The adaptation process followed international guidelines, including back-translation and expert evaluation. Rasch analysis, test-retest reliability, and concurrent validity assessments were performed.The SPaRQ-T demonstrated strong internal consistency (Cronbach's α = 0.926 for Social Behaviors and 0.871 for Social Perceptions) and test-retest reliability (ICC = 0.928 and 0.773, respectively). Rasch analysis confirmed the unidimensionality of both subscales and supported good model fit. The SPaRQ-T is a reliable and valid instrument for assessing social participation restrictions in Turkish-speaking adults with hearing loss. It provides a comprehensive evaluation of the social and emotional dimensions of participation and can be used in clinical and research settings.
