Abstract Hearing loss is a potentially disabling problem among elderly leading to physical and social dysfunction. Though audiometric assessment of hearing loss is considered as gold standard, it is not feasible in community settings. Several questionnaires measuring hearing handicap have been developed. Knowledge regarding applicability of these questionnaires among rural elderly is limited, hence a study was planned to validate single question and Shortened Hearing Handicap Inventory for Elderly (HHIE-S) in detecting hearing loss against pure tone-audiometry among rural Indian elderly. A single question ‘do you feel you have a hearing loss?’ and the HHIE-S was administered to 175 elderly in two rural areas. Hearing ability was assessed using pure tone audiometry. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of both screening tools were compared with pure tone averages (PTAs) greater than 25, 40 and 55 dB hearing level (mild, moderate and severe hearing loss, respectively). The single question yielded low sensitivity (30.9%) and high specificity (93.9%) for mild hearing loss. Similarly HHIE-S yielded a sensitivity of 26.2% and specificity of 95.9%. Sensitivity with single question increased to 76.2% and specificity decreased to 83.1% with severe hearing loss. Sensitivity with HHIE-S also increased to 76.2% and specificity decreased to 87.7% with severe hearing loss. These hearing screening questionnaires will be useful in identifying more disabling hearing losses among rural elderly which helps in rehabilitation services planning.
