Abstract
- 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.
