Development of Korean Version of Profile of Hearing Aid Benefit-Quick Version

Abstract

Purpose: The purpose of this study was to develop the Korean version of profile of hearing aid benefit-quick version (K-PHAB-Q) which shortens 20 questions of K-PHAB into 10 for efficient evaluation of hearing aids benefit. Methods: First, responses for the questionnaires were collected from 140 hearing aid users (average age: 67.39). K-PHAB-Q consists of ease of communication (EC), background noise (BN), reverberation (RV), aversiveness of sounds (AV) and localization (LC), and was verified through factor analysis, principal component analysis, and Cronbach’s alpha analysis for a total of 10 selected items. Second, the K-PHAB-Q questionnaire was collected by test-retesting for a total of 40 hearing aid users (average age: 71.98). The collected questionnaires were verified by paired <i>t</i>-test and Pearson correlation coefficient, and the 95% prediction interval (PI) was calculated to establish the standard of change in subjective satisfaction on hearing aid users. Results: The results of this study were 1) according to Cronbach’s alpha analysis of K-PHAB-Q, the internal consistency of all items was high as 0.854, 2) test-retest result of K-PHAB-Q showed no significant difference (r > 0.05) and showed high correlation in all items, 3) The 95% PI of EC, BN, RV, AV, and LC showed ± 16.823, ± 17.734, ± 12.123, ± 14.404, and ± 8.193 respectively. Conclusion: K-PHAB-Q, will be useful for hearing aid verification or validation at hearing aid fitting management sites in a short time.
