Purpose: The purpose of this study was to develop a questionnaire to assess gain of wearing hearing aid and to verify its reliabilityand validity. Methods: A total of 141 (average age: 65.7) hearing-impaired listeners participated in a survey for selection of items and
24 (average age: 72.67) hearing aid wearers participated in test-retest reliability test. In order to verify reliability and validity of Korean
version-Profile of Hearing Aid Benefit (K-PHAB), factor analysis, Cronbach’s alpha, a test-retest reliability (paired t-test, Pearson correlation
coefficient), and 95% prediction interval were applied. Results: The results of this study were as below: 1) K-PHAB which was
constructed through factor analysis after questionnaire survey on the selection of items was composed of ease of communication,
background noise, reverberation, aversiveness of sounds and localization with a total of 20 items, 2) the result of factor analysis showed
good construct validity, 3) the Cronbach’s alpha coefficient appeared to be 0.75-0.81, showing a high level of reliability, 4) the testretest
correlation coefficient had high values such as 0.82-0.96, 5) 95% prediction interval for each category was ranged from ±9.78
to ±13.78. Conclusion: K-PHAB had good reliability and validity, and could be used to measure the wearing effect of a hearing aid subjectively
and specifically upon auditory rehabilitation of hearing aid wearers.
