BACKGROUND AND OBJECTIVES: MarkeTrak Survey is designed to evaluate the sociodemographic and HA factors of hearing aid (HA) users and their satisfaction of use. The questionnaire is inconvenient to use because it asked too many questions and requires long time to answer. The purpose of this study was to develop a simplified ("Ajou") version of MarkeTrak Survey and to evaluate its reliability. SUBJECTS AND METHOD: Forty-five HA users who visited the Ajou Hearing Center from 2014 to 2015 were included in the present study. To examine the correlation of the Korean version and the Ajou version of MarkeTrak Survey, 42 patients completed each survey simultaneously. To examine the reliability of Ajou version, test-retest and internal consistency methods were used. For the test-retest method, 22 HA users repeated the survey 2-4 weeks later. RESULTS: The newly developed "Ajou" version of MarkeTrak Survey consisted of 12 questions and was more simplified. Most of the questions of the two surveys showed significant correlation coefficient values (Spearman correlation, p<0.05). For the test-retest method, most questions showed significant correlation coefficient values (Spearman correlation, p<0.05), but they showed lower values than 0.6 in many cases. It showed high internal consistency of overall HA satisfaction. CONCLUSION: The Ajou version may be used as a simplified and alternative questionnaire for the Korean version of MarkeTrak Survey.

BACKGROUND AND OBJECTIVE: This investigation evaluated the level of subjective satisfaction in hearing aid users by using Abbrieviate Profile of Hearing Aid Benefit (APHAB). MATERIALS AND METHODS: The APHAB is a subjective evaluation method for hearing aid users. The APHAB consists of 24 items with 4 subscales including Ease of Communication (EC), Reverberation (RV), Background noise (BN), and Aversiveness (AV). 3Ve applied for APHAR to evaluate the subjective satisfaction level in 45 compressive types of hearing aids. The APHAB scores were evaluated according to the types of hearing loss, audiologic patterns of pure tone audiograms, the degree of SRT and the types of hearing aids. In each item, subjects respond to each question on the basis of how they believe the performance of their hearing aid is using a 7-point scale. Subjects were tested both unaided and aided for each specified listening situation. The hearing aid benefit is defined as the diR'erence of percentage between the unaided and aided performance scores. RESULTS: In SRT, moderate hearing loss group showed a higher satisfaction in Ease of Communication, Aversiveness (p<0.05). The group that showed a flat audiogram revealed a higher satisfaction in Ease of Communication, Background noise (p<0.01). There was no significant difference of scores of benefit in types of hearing loss and types of hearing aids. CONCLUSION: Hearing aids are more beneficial in patients who have moderate hearing loss and flat audiogram pattern.
