Background: Hearing loss increases with age and due to increased life expectancy there is an increase in the number of individualsliving with hearing loss. Older people with hearing loss residing in nursing homes are often dependent on healthcare professionals tohelp them with their hearing aids.Objective: The aim of the study was to translate and test the psychometric properties of a Swedish version of a Norwegianquestionnaire and to assess healthcare professionals’ self-reported knowledge, experience, skills, competence, and informationneeds pertaining to residents’ hearing loss and hearing aids in the Swedish context.Materials and Methods: A Norwegian questionnaire was translated and adapted, and thereafter distributed to healthcare professionals in nine nursing homes in mid Sweden between 2020 and 2021, and 313 questionnaires were returned.Results: An exploratory factor analysis demonstrated adequate factorial structure in six factors, satisfying construct validity andinternal consistency for the Swedish version. A confirmatory factor analysis showed a satisfactory model fit. Healthcare professionalsreported having the skills required for handling hearing aids, but reported lower scores for having received information about hearingaids, taking initiatives to refer residents to hearing healthcare units, and checking for earwax. Registered nurses generally reportedlower perceived knowledge and practical skills concerning hearing aids. Seventy-seven percent of the total group reported a need forinformation regarding hearing aid maintenance.Conclusion: Healthcare professionals reported that the majority of nursing home residents need help with their hearing aids, but onlya minority of these professionals had received education on hearing loss and training in hearing aid maintenance. Enrolled nurses and careassistants demonstrated higher levels of competence in handling hearing aids compared to registered nurses. In order to ensure safe and effectivecare, as well as facilitate communication among older adults with hearing loss, healthcare professionals need appropriate education and training.
