Self-Reported Hearing Outcomes in Kannada-Speaking Hearing Aid Users: Interplay of Audiological Profile, Device usage and Socio-Educational Factors
摘要
Self-reported outcome measures are patient-centered tools that evaluate hearing disability, severity and treatment effectiveness. While the impact of hearing loss (HL) on unaided self-reported disability has been studied, a comprehensive analysis of its relationship with specific handicap measures, especially in India, is lacking. This study bridges this gap by assessing the impact of HL severity on self-reported hearing outcomes among native Kannada-speaking adults. This cross-sectional study involved 60 Kannada-speaking individuals (18–75 years) with acquired sensorineural hearing loss (SNHL) using hearing aids. Based on pure-tone average in the better ear, they were categorized into mild-moderate SNHL (n = 30) and moderately severe-severe SNHL (n = 30). Audiological, hearing aid usage, and socio-educational profiles of the participants were noted along with administration of six self-reported questionnaires in Kannada language. The outcome measures administered were International Outcome Inventory for Hearing Aids (IOI-HA), the Hearing Handicap Questionnaire (HHQ), the Self-Assessment of Communication (SAC), the Participation Scale (PS), the Assessment of quality of life in 4 dimensions (AQol-4D) and the Communication Strategy Scale (CSS), a sub-scale of the Communication Profile for Hearing Impaired (CPHI). The Mann-Whitney U test results highlighted the significant effect of degree of HL severity on four out of six questionnaires tested (i.e. IOI-HA, SAC, PS, & AQol-4D). Spearman’s rank correlation analysis showed a significant correlation between audiological, device usage and, socio-educational characteristics with the self-reported difficulties in hearing aid users. Findings suggest that different degrees of HL significantly influence self-reported outcome measures, affecting communication environment choices, social and emotional participation, and satisfaction from hearing aid. However, the use of communication strategies, and perceived hearing disability remain largely unaffected by the degree of hearing loss.
