Identifying Hearing Loss and Audiological Rehabilitation Candidacy Through Self-Perceived Hearing Handicap Using the Croatian Version of the Hearing Handicap Inventory for the Elderly-Screening (HHIE-S-CRO).

Abstract

Background/Objectives: This study aimed to: (1) evaluate the effectiveness of the Croatian version of the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S-CRO) in screening for hearing loss greater than 20 dB HL in the better-hearing ear among adults aged ≥ 60 years; (2) assess its utility in identifying individuals with hearing loss ≥ 40 dB HL in the better-hearing ear, meeting current Croatian eligibility criteria for state-funded hearing aid rehabilitation; and (3) determine whether the emotional and social components of perceived hearing handicap can be meaningfully distinguished. Methods: Validity of the HHIE-S-CRO was analyzed using Spearman's correlation coefficient, the Mann-Whitney test and the factor analysis, while reliability was assessed via Cronbach's alpha and the intraclass correlation coefficient (ICC). Receiver operating characteristic (ROC) curve analysis was calculated to determine sensitivity, specificity, and positive and negative predictive values (PPV and NPV) at various cut-off scores of the HHIE-S-CRO total for specified audiometric criteria (better ear pure-tone average > 20 dB HL and ≥40 dB HL). The nonparametric Wilcoxon Matched Pairs Test was used to compare scores on the emotional and social subscales of the HHIE-S-CRO. Results: The HHIE-S-CRO demonstrated excellent internal consistency (Cronbach's alpha = 0.92) and high repeatability of the results (ICC = 0.92). Discriminant, convergent, construct and predictive validity were confirmed. The area under the curve (AUC) for detecting hearing loss > 20 dB HL in the better ear was 0.95, with a sensitivity of 90.67% and specificity of 94.65% at a cut-off score of 6. For the Croatian threshold for state-supported hearing aid rehabilitation (≥40 dB HL in the better-hearing ear), similarly favorable screening characteristics were found at a cut-off score of 10. Conclusions: Based on these findings, the HHIE-S-CRO appears to offer sufficient sensitivity and specificity to support two key clinical applications: (1) screening for hearing loss > 20 dB HL in individuals aged 60 and older, and (2) identifying individuals within this age group who may be eligible for state-supported hearing aid-based rehabilitation.
