Development and Transadaptation of Voice Handicap Index-Bangla

Abstract

The present study aimed to transadapt and validates the Voice Handicap Index in Bangla language. The objective of the study was to develop and validate a vernacular test which would be beneficial for assessment of functional impact of voice disorders. The present study consisted of 60 participants (30 male and 30 female) within the age range of 18 - 60 years. The test was translated, back translated and later assessed for face and validity and reliability. The internal consistency of the test items showed high reliability (Cronbach’s α = 0.865). Most of the questionnaires such as the Voice Handicap Index (Jacobson et al.,1997) that evaluate the ‘quality of life’ related with voice were developed in English and were intended to be used in English speaking countries. Hence a development of vernacular test was pertinent thus Voice Handicapped index –Bangla was developed.
