Plain English Summary

Background and study aims
Usual hearing health care is mostly restricted to hearing assessment and hearing aid fitting. There is growing evidence showing that to increase a hearing-impaired individual’s communication and coping with hearing impairment in daily life, more than hearing aid fitting alone is needed. Training of communication strategies is an example of an intervention that may improve a person’s communication in daily life. Recently, an (online) audiologic rehabilitation support program (SUPR) was re-developed in collaboration with hearing care professionals. The main elements are an instruction book including exercises, frequent contact by email with a hearing expert, training modules covering short films with instructions for daily life situations and testimonials consisting of experiences from other peer hearing aid users. The aim of this study is to test the effectiveness of the support programme (SUPR) in hearing-impaired hearing aid users and their communication partners.

Who can participate?
Hearing-impaired hearing aid users, aged 50 and over, including both first-time hearing aid users and experienced hearing aid users, and their communication partners.

What does the study involve?
Hearing aid dispenser shops are randomly allocated to offer their customers either care as usual (hearing aid care) or hearing aid care including the SUPR support programme. Measurements are performed at the start of the study and after 6, 12 and 18 months. The following are assessed: coping, basic hearing aid handling, actual use of the hearing aid, satisfaction with the hearing care professional service, hearing disability.

What are the possible benefits and risks of participating?
A potential benefit of participation in the support program group is obtaining knowledge on how to cope with hearing impairment in daily life (listening) situations by learning communication strategies. Contributing to the scientific knowledge on the effectiveness of rehabilitation for hearing-impaired adults and their communication partners can also be seen as a benefit of participating. There are no risks associated with participation.

Where is the study run from?
70 hearing aid dispenser shops in the Netherlands

When is the study starting and how long is it expected to run for?
February 2015 to December 2017

To improve hearing-impaired individuals' communication and coping with their disability, more than hearing aid fitting alone is needed.


At the beginning of the study hearing aid dispenser shops will be randomly assigned to offer care as usual (hearing aid care) or hearing aid care including SP. This means that the clusters are defined at the start of the study and the particular hearing aid dispenser shop that the participant visits automatically determines to which group the participant is assigned (Care as Usual or SP). To avoid an unequal distribution of the level of urbanization across the participants of the two groups, shops will be pre-stratified on different levels of urbanization and the randomisation will subsequently be performed within these different strata. The level of urbanization is based on the level of the particular municipality that the shop is localized in. A statistician will perform block randomisation, with blocks of four.

The support programme (SP) is designed to help hearing-impaired individuals use their hearing aid more effectively and to improve successful coping strategies, as compared to usual hearing aid care. All participants, including the ones assigned to the control group, are asked to assign a communication partner; a person with whom the participant has regular contact. The communication partner plays an important role in enhancing the motivation of the participant.

Participants who are assigned to the SP arm will be provided with the support programme for a period of six months (two month trial period and four months afterwards) in addition to receiving usual care in the context of hearing aid fitting. The Support Program consists of the Practical Support Book and the following components offered via email:
1. Contact with the hearing aid dispenser, in order to support the user during the first and most crucial trial period of the hearing aid
2. Training modules including:
2.1. Instruction videos with practical information on how to use and maintain a hearing aid
2.2. The educational programme “Horen en Gehoord Worden: Hoe kan het beter”, developed by Kramer et al. (2005). It comprises five short films regarding difficulties experienced by hearing-impaired older persons in everyday life situations. How to improve communication by using certain communication strategies is shown
2.3. Testimonials by hearing-impaired peers, in order to increase acceptation of hearing impairment. In these short films peer hearing aid users share their experiences.

Participants who are assigned to the control group will be provided with usual care in the context of hearing aid fitting.

Intervention type



Drug names

Primary outcome measures

Coping with hearing loss, measured with the Communication Profile for the Hearing Impaired (CPHI) at baseline and after 6 (T1), 12 (T2) and 18 (T3) months

Secondary outcome measures

1. Self-efficacy of hearing aid use and will be measured by the Basic Handling subscale of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA) at baseline, T1, T2 and T3. At baseline it covers the ‘expected self-efficacy’ of the new hearing aid, while T1, T2 and T3 prompts the ‘experienced self-efficacy’
2. Actual use of the hearing aid/or use of the 'Alternative Intervention' will be measured with the first item of the International Outcome Inventory – Hearing Aids / International Outcome Inventory – Alternative Interventions questionnaire (IOI-HA/IOI-AI). In addition, data-logging within the hearing aid will be used to measure the hearing aid use. Hearing aid use/use of the alternative intervention will only be measured at T1, T2 and T3. Furthermore, three questions from the Questionnaire regarding hearing aid usage developed by Laplante-Lévesque and colleagues will be used
3. Efficacy of the hearing aid/alternative intervention will be measured by items of the IOI-HA/IOI-AI questionnaire: benefit (item 2), residual activity limitation (3), satisfaction (4), residual participation restriction (5), impact on others (6) and quality of life (7) of the hearing aid and/or the alternative intervention. These IOI- items will also only be assessed at T1, T2, and T3
4. Satisfaction with the hearing aid dispenser’s service will be measured by the Net Promoter Score. It will be measured at baseline, T1, T2 and T3
5. Self-reported hearing status will be measured using the Amsterdam Inventory for Auditory Disability and Handicap (AIADH) and will be measured at baseline, T1, T2 and T3
6, Stage of behaviour change will be measured by the University of Rhode Island Change Assessment- for Hearing health behaviour (URICA) and will be measured at baseline, T1, T2 and T3
7. Emotional response to hearing problems will be measured with the 'emotional response' section from the Hearing Handicap and Disability Inventory at baseline, T1, T2 and T3

Among the communication partners these outcomes will be measured:
1. Third-party disability will be measured with the Significant Other Scale for Hearing Disability (SOS-HEAR) at baseline, T1, T2 and T3
2. Efficacy outcomes of the hearing aid/intervention from the perspective of the significant other will be administered: Use, benefit, residual activity limitation, satisfaction, residual participation restriction, impact on others and quality of life. The 7-item IOI-HA-SO/IOI-AI-SO will be used at T1, T2 and T3

Age group




Target number of participants

A number of 258 first-time hearing aid users and 311 experienced hearing aid users need to be recruited

Participant exclusion criteria

Hearing aid dispenser clients who:
1. Also receive care at a specialized Audiological Clinic, since this mostly involves people with complex hearing disabilities. This care may overlap and/or interfere with that of the support programme
2. Receive a hearing aid primarily to suppress tinnitus complaints. For these individuals the focus of the rehabilitation is not on restoring communication per se and as such, they are not part of the target group
