简要总结
Knowledge about how to manage hearing aids is an important factor in hearing aid success, but studies show that this knowledge ranges from good to poor, even among experienced adult hearing aid users. Information leaflets is a common tool in healthcare to give information with the purpose to increase theoretical knowledge and change behaviour, and illustrations in these leaflets can provide additional understanding for all kinds of patients.
The primary aim of this aural rehabiliation study was to evaluate participants' knowledge about placement in a noisy environment, directional microphone and telecoil function at baseline and postintervention and assessing their perceptions of the benefits of an information leaflet. Additional aim was to investigate whether, an information leaflet with illustrations and accompanying text about hearing aid functions have additional effects on participants' knowledge compared to an information leaflet without illustrations.

结局指标
主要结局
Perceived benefit
时间窗: 3 weeks postintervention
Assessing the perceived benefit of the information leaflet through three items formulated as statements and ranged from (0) not agree at all to (10) completely agree. The statements were as follows: 1) the written information I received has increased my understanding of the functions of the hearing aid, and 2) the written information I received has made me better understand how to position myself in different sound environments. If applicable, 3) the written information I received made it easier for me to explain the functions of my hearing aid to a communication partner.
Knowledge about hearing aid functions
时间窗: Baseline, 3 weeks postintervention
Assessing change in knowledge about placement in noisy environments, telecoil function and directional microphones. Open-ended questions where the knowledge assessed by two authors independently of each other, to make the answers quantitative. Interrater reliability was analysed with Cohen's kappa
