A validation study of the Swedish version of the Glasgow hearing aid benefit profile evaluated in otosclerosis subjects

• Objectives The aim of this study was to translate the Glasgow Benefit Hearing Aid Profile (GHABP) to Swedish, and to analyze its validity and reliability in patients undergoing rehabilitation with surgery or hearing aids. Methods The GHABP was translated to Swedish following published guidelines. One version of the questionnaire was adapted to fit the surgical intervention. A modification was made to the questionnaire by removing the answer option "not applicable" (N/A) since it was found confusing by the subjects. A prospective multicenter cohort study was performed to validate the questionnaire. One hundred and twenty-three individuals diagnosed with otosclerosis were included in the study prior to the intervention. The individuals were divided into three groups based on the intervention and previous hearing aid experience. Pure tone audiometry was performed 1 month prior and 1 year after the intervention. The Swedish version of the GHABP was completed by the individuals prior to the intervention, as well as 6 and 12 months after the intervention. Validity and reliability were assessed. Results The Swedish versions of the GHABP were well accepted by the included individuals. The questionnaires showed good psychometric properties, with comparable results for the two different interventions and three separate intervention groups. Initial disability was more pronounced in more challenging listening situations. Disability was reduced after the intervention. The "Use," "Benefit," and "Satisfaction" domains demonstrated beneficial results; however, a ceiling effect was noted in the same domains. The reliability was overall very high. Conclusion The Swedish version of the GHABP had good psychometric properties, with high validity and reliability. The same outcomes were found for the hearing aid and surgery groups. A ceiling effect was observed that can affect the questionnaire's ability to distinguish between subjects and measures over time. Level of evidence 2c
