Abstract

ABSTRACT
Background: The aim of this study was to prepare the Persian version of The Speech, Spatial and Qualities of Hearing Scale questionnaire-12 (SSQ-12-persian version) and to assess its validity and reliability to facilitate the investigation of the effect of the usage of hearing aids on individuals using them.
Methods: This is a cross-sectional study. The questionnaire was translated to Persian according to WHO method. Firstly, two fluent Persian-speaking translators, translated the questionnaire from Persian to English and then three audiologists examined the questionnaire. In the last step, two bilingual translators translated the questionnaire from Persian to English and were evaluated conceptually. Finally, the Persian version of the SSQ12 questionnaire was voluntarily presented to 99 elderly people aged 22 to 52 years hearing aids users whom hearing thresholds were measured recently. For assessing reliability and validity and test-retest reliability T-test examination and Cronbach Alpha was used.
Results: Persian version of SSQ12 questionnaire shown high internal consistency (assessed by Cronbach Alpha = 0.924) and high test-retest (assessed by Cronbach Alpha = 0.868) reliability.
Conclusion: The ssq12 questionnaire is a comprehensive summary of the SSQ49 questionnaire. It would be one of the valid questionnaires for evaluating hearing performance improvement in hearing aids users. This study showed that the Persian version of ssq-12 questionnaire has high reliability and validity regarding Paired Sample t-test (p<0.001) and Cronbach’s alpha showed that the questionnaire has high internal consistency (Cronbach’s alpha =0.924). The reliability of test-retest after a month was obtained and the total scale result was 0.867. According to results of this study SSQ-12 can be used as other Persian translated questionnaires like GHABP, SHQ, IOI-HA for examining the effectiveness of hearing aids and their effects on limiting disabilities related to hearing loss.
