Abstract

BACKGROUND AND OBJECTIVES
The Speech, Spatial and Qualities of Hearing Scale (SSQ) was designed to measure self-reported auditory disability in a wide variety of listening situations. Its 49 items cover many aspects of speech perception, spatial hearing, and qualities of hearing, which constitute the three parts of SSQ. However, there has been no reliable and valid Korean version of SSQ (K-SSQ), which made the measurement of auditory disability difficult. The aim of this study is to develop a K-SSQ and to determine its reliability and validity for clinical or academic use.
SUBJECTS AND METHOD
An expert panel translated the original SSQ into Korean. A bilingual translator back-translated the translated version into English, which was then compared with the original version. After cognitive debriefing, K-SSQ was administered to 400 patients with hearing disability in 14 referral hospitals. Reliability was assessed using Cronbach's alpha coefficient and correlation study. Validity was evaluated by factor analysis and criterion validity based on the results of pure tone audiometry.
RESULTS
K-SSQ showed good reliability with high internal consistency (Cronbach's α=0.99), and strong positive correlations across all three parts of SSQ. Construct validity was confirmed by the results of factor analysis and criterion validity demonstrated positive correlations between each part of SSQ and the results of pure tone audiometry.
CONCLUSION
The K-SSQ is a reliable and valid tool for use as a behavioral measure of hearing ability in Korean-speaking patients, and it will provide a very useful evaluation tool for both clinicians and researchers.
