Turkish Validity and Reliability Study of the Speech, Spatial and Qualities of Hearing Scale

Abstract

Objective:The Speech, Spatial and Qualities of Hearing Scale (SSQ) is a self-report scale that evaluates hearing in complex daily life situations in the areas of hearing quality, speech perception, and spatial perception. It is also frequently used in the follow-up of hearing-impaired people, hearing aid and cochlear implant users. It is aimed to translate and adapt SSQ into Turkish, and to investigate its test-retest reliability, and construct validity and reliability, and further to present associations of SSQ scores with the pure tone averages (PTA).Methods:The Turkish SSQ (Tr-SSQ) scale was administered on 114 adults including those with and without hearing loss. Cronbach’s alpha was used to assess its reliability. The reliability coefficient of the scale was calculated by test-retest method. Associations of SSQ scores with PTAs in better and worse hearing ears (BHE and WHE) were evaluated.Results:Tr-SSQ presented high internal consistency (Cronbach’s alpha = 0.984) and test-retest reliability (r=0.994). Tr-SSQ scores were lower in the subjects with hearing loss and correlated with PTAs. Age was found to be correlated with PTAs; regression analysis demonstrated that only WHE-PTA was extracted as explanatory variable for average Tr-SSQ, speech perception and spatial perception scores while both BHE-PTA and WHE-PTA were found to be predictors of hearing quality, but not age for any of Tr-SSQ scores.Conclusion:Tr-SSQ is a convenient tool for assessing the hearing abilities of individuals with hearing impaired.
