Development and Standardization of Hearing Handicap Inventory for Adult (Screening Version) in Nepali Language

Hearing handicap inventory for adult- screening version (HHIA-S) is one of the widely used questionnaire for assessing hearing handicap among adult population over the short period of time. This questionnaire has been translated in many languages worldwide including Indian, Sweden, and Spanish. However, there is lack of such questionnaire in Nepali language. Hence, this study is aimed at developing and standardizing the HHIA-S questionnaire in Nepali language. The English version of the HHIA-S was translated to the Nepali language using the translation-back-translation method. Further, it was given to 10 native Nepali speakers for content validation. The final HHIA-S Nepali version was then administered to 70 normal native Nepali speakers and 50 hearing impaired Nepali speaker. The responses were analyzed, and Cronbach's alpha was calculated to measure the internal consistency of the questionnaire. Results showed that the HHIA-S Nepali version has a Cronbach's alpha score of 0.94 for normal hearing group and 0.93 for hearing impaired group, which is considered good reliability. The HHIA-S Nepali version developed in this study is found to be valid and reliable. Hence, it can be used as a screening tool for assessing hearing handicap among Nepali population.
