Validation of the Korean Version of the Abbreviated Profile of Hearing Aid Benefit

Abstract

BACKGROUND AND OBJECTIVES: The quantificathe benefit of using hearing aids. In this study, we developed a Korean version of APHAB (K-APHAB) and determined its validity and reliability. SUBJECTS AND METHOD: An expert panel translated the original version of APHAB into Korean language. Two bilingual translators back-translated the first translated version into English and it was compared with the otion of hearing aid benefit is important in hearing aid fitting. The abbreviated profile of hearing aid benefit (APHAB) is a useful tool for measuring riginal version. After cognitive debriefing, the translation of APHAB into the Korean version was completed. One hundred ninety-seven subjects using hearing aids participated in this study and completed K-APHAB. Reliability was assessed using Cronbach's alpha coefficient, and validity was evaluated by factor analysis and criterion validity. RESULTS: K-APHAB had a good internal consistency (α=0.80). Confirmatory factor analysis showed that K-APHAB is comprised of four subsections, namely ‘communication in daily life, ‘aversiveness, communication in ‘background noise or ‘reverberation. CONCLUSION: The K-APHAB is a useful tool for evaluating the benefit of hearing aids in Korean hearing-impaired individuals.
