Evaluating a Theoretically Informed and Cocreated Mobile Health Educational Intervention for First-Time Hearing Aid Users: Qualitative Interview Study

Refinement and Validation of the Empowerment Audiology Questionnaire: Rasch Analysis and Traditional Psychometric Evaluation

OBJECTIVES

Empowerment is the process through which individuals with hearing-related challenges acquire and use knowledge, skills and strategies, and increase self-efficacy, participation, and control of their hearing health care, hearing solutions, and everyday lives. The aim was to refine and validate the Empowerment Audiology Questionnaire (EmpAQ), a hearing-specific measure of empowerment. This was achieved through (1) refinement via Rasch analysis (study 1), and (2) traditional psychometric analysis of the final survey structure (study 2).

DESIGN

In study 1, 307 adult hearing aid owners completed the initial empowerment measure (33 items) online. To inform an intended item reduction, Rasch analysis was used to assess a range of psychometric properties for individual items. The psychometric properties included analysis of individual items (e.g., response dependency, fit to the polytomous Rasch model, threshold ordering) and the whole EmpAQ (e.g., dimensionality). Item reduction resulted in a 15-item version (EmpAQ-15) and a short-form 5-item version (EmpAQ-5), validated using modern (Rasch), and traditional (Classical Test Theory) psychometric analysis (study 2). In study 2, 178 adult hearing aid owners completed the EmpAQ-15 and EmpAQ-5, alongside 5 questionnaires to measure related constructs. These included two hearing-specific questionnaires (Social Participation Restrictions Questionnaire and Self-Assessment of Communication), two general health-related questionnaires (Patient Activation Measure and World Health Organization Disability Assessment Schedule 2.0), and a general empowerment questionnaire (Health Care Empowerment Questionnaire). Modern (Rasch) and traditional psychometric analysis techniques (internal consistency, construct validity, and criterion validity) were used to assess the psychometric properties of the EmpAQ-15 and EmpAQ-5.

RESULTS

Rasch analysis of the initial 33-item measure of empowerment identified 18 items with high response dependency, poor fit to the Rasch model, and threshold disordering, which were removed, resulting in a long-form (EmpAQ-15) hearing-specific measure of empowerment. A short-form (EmpAQ-5) version was developed for use in the clinic setting. Validation of the two EmpAQ measures using Rasch analysis showed good item fit to the Rasch model, appropriate threshold targeting, and the existence of unidimensionality. Traditional psychometric evaluation showed that both questionnaires had high internal consistency and positive correlations with the hearing-specific questionnaires. However, in contrast with our hypotheses, correlations with general health questionnaires were stronger than with hearing-specific questionnaires; all questionnaires were correlated with the EmpAQ and in the direction hypothesized. Taken together, these findings support the construct validity of the EmpAQ-15 and EmpAQ-5.

CONCLUSIONS

The EmpAQ-15 and EmpAQ-5 are the first self-report measures to be developed specifically for the measurement of empowerment. The EmpAQ-15 and EmpAQ-5 were found to meet the Rasch model criteria for interval-level measurements. Traditional psychometric evaluation supports the construct validity of both measures. The EmpAQ measures have the potential to be used in both research and clinical practice to evaluate empowerment along the hearing journey. The next stage of this research will be to further validate these measures by assessing their responsiveness, minimal clinically important difference, and clinical interpretability in a clinical population.

Development of a self-report measure of empowerment along the hearing health journey: a content evaluation study

OBJECTIVE

To conduct the first phases in the development of a self-report measure of empowerment on the hearing health journey, specifically, item generation and content evaluation of the initial pool of items generated.

DESIGN

A content expert panel survey and cognitive interviews were conducted. Descriptive statistics were obtained for the quantitative data, and the cognitive interviews were analysed using thematic analysis.

STUDY SAMPLE

Eleven researchers and clinicians participated in the content expert surveys. Sixteen experienced hearing aid users participated in the cognitive interviews, recruited from the USA and Australia.

RESULTS

The items underwent five iterations based on feedback from the survey and interview data. This resulted in a set of 33 quality-tested potential survey items that were rated highly for relevance (mean = 3.96), clarity (mean = 3.70) and fit to dimensions of empowerment (mean = 3.92) (scale 0-4, where 4 was the maximum rating).

CONCLUSIONS

Involving stakeholders in item generation and content evaluation increased relevance, clarity, fit to dimension, comprehensiveness, and acceptability of the items. This preliminary version of the 33-item measure underwent further psychometric refinement (Rasch analysis and traditional classical test theory testing) to validate it for clinical and research use (reported separately).

The development and evaluation of an online hearing loss prevention program

Recent studies underline the need for research on approaches to encouraging healthy listening habits. This study aims to develop and evaluate an online hearing loss prevention program; and examine its influence on the participants' use of hearing protection, hearing loss prevention knowledge, attitude towards noise, and program useability and adherence. The study was conducted in the county of Västra Götaland, Sweden, from March through October 2021. The program included four modules focused on hearing and hearing loss prevention and was accessible to the participants for four weeks. In total, 75 participants completed the program which was evaluated using the Youth Attitude to Noise Scale and four additional self-designed questionnaires. The questionnaires were deployed before and immediately after program completion. The findings indicate that the program may influence the participants' attitudes toward noise and the use of hearing protection. The participants who completed the program perceived high useability and increased hearing loss prevention knowledge. This program is most needed to promote healthy hearing. Future studies should target specific groups with this program and evaluate its long-term effects.

Remote Technologies to Enhance Service Delivery for Adults: Clinical Research Perspectives

There are many examples of remote technologies that are clinically effective and provide numerous benefits to adults with hearing loss. Despite this, the uptake of remote technologies for hearing healthcare has been both low and slow until the onset of the COVID-19 pandemic, which has been a key driver for change globally. The time is now right to take advantage of the many benefits that remote technologies offer, through clinical, consumer, or hybrid services and channels. These include greater access and choice, better interactivity and engagement, and tailoring of technologies to individual needs, leading to clients who are better informed, enabled, and empowered to self-manage their hearing loss. This article provides an overview of the clinical research evidence-base across a range of remote technologies along the hearing health journey. This includes qualitative, as well as quantitative, methods to ensure the end-users' voice is at the core of the research, thereby promoting person-centered principles. Most of these remote technologies are available and some are already in use, albeit not widespread. Finally, whenever new technologies or processes are implemented into services, be they clinical, hybrid, or consumer, careful consideration needs to be given to the required behavior change of the key people (e.g., clients and service providers) to facilitate and optimize implementation.

Identifying barriers and facilitators of hearing protection use in early-career musicians: a basis for designing interventions to promote uptake and sustained use

OBJECTIVE

The current study aimed to: i) determine the patterns of hearing protection device (HPD) use in early-career musicians, ii) identify barriers to and facilitators of HPD use, and iii) use the Behaviour Change Wheel (BCW) to develop an intervention to increase uptake and sustained use of HPDs.

DESIGN

A mixed-methods approach using questionnaires and semi-structured interviews.

STUDY SAMPLE

Eighty early-career musicians (age range = 18-26 years; women n = 39), across all categories of musical instrument.

RESULTS

42.5% percent of participants reported using HPDs at least once a week, 35% less than once a week, and 22.5% reported never using HPDs for music-related activities. Six barriers and four facilitators of HPD use were identified. Barriers include the impact of HPDs on listening to music and performing, and a lack of concern about noise exposure. Barriers/facilitators were mapped onto the Theoretical Domains Framework. Following the systematic process of the BCW, our proposed intervention strategies are based on 'Environmental Restructuring', such as providing prompts to increase awareness of noisy settings, and 'Persuasion/Modelling', such as providing credible role models.

CONCLUSIONS

For the first time, the present study demonstrates the use of the BCW for designing interventions in the context of hearing conservation.

Auditory Perceptual Exercises in Adults Adapting to the Use of Hearing Aids

Older adults with age-related hearing loss often use hearing aids (HAs) to compensate. However, certain challenges in speech perception, especially in noise still exist, despite today's HA technology. The current study presents an evaluation of a home-based auditory exercises program that can be used during the adaptation process for HA use. The home-based program was developed at a time when telemedicine became prominent in part due to the COVID-19 pandemic. The study included 53 older adults with age-related symmetrical sensorineural hearing loss. They were divided into three groups depending on their experience using HAs. Group 1: Experienced users (participants who used bilateral HAs for at least 2 years). Group 2: New users (participants who were fitted with bilateral HAs for the first time). Group 3: Non-users. These three groups underwent auditory exercises for 3 weeks. The auditory tasks included auditory detection, auditory discrimination, and auditory identification, as well as comprehension with basic (syllables) and more complex (sentences) stimuli, presented in quiet and in noisy listening conditions. All participants completed self-assessment questionnaires before and after the auditory exercises program and underwent a cognitive test at the end. Self-assessed improvements in hearing ability were observed across the HA users groups, with significant changes described by new users. Overall, speech perception in noise was poorer than in quiet. Speech perception accuracy was poorer in the non-users group compared to the users in all tasks. In sessions where stimuli were presented in quiet, similar performance was observed among new and experienced uses. New users performed significantly better than non-users in all speech in noise tasks; however, compared to the experienced users, performance differences depended on task difficulty. The findings indicate that HA users, even new users, had better perceptual performance than their peers who did not receive hearing aids.

Diagnostic Accuracy of Smartphone-Based Audiometry for Hearing Loss Detection: Meta-analysis

Background

Hearing loss is one of the most common disabilities worldwide and affects both individual and public health. Pure tone audiometry (PTA) is the gold standard for hearing assessment, but it is often not available in many settings, given its high cost and demand for human resources. Smartphone-based audiometry may be equally effective and can improve access to adequate hearing evaluations.

Objective

The aim of this systematic review is to synthesize the current evidence of the role of smartphone-based audiometry in hearing assessments and further explore the factors that influence its diagnostic accuracy.

Methods

Five databases—PubMed, Embase, Cochrane Library, Web of Science, and Scopus—were queried to identify original studies that examined the diagnostic accuracy of hearing loss measurement using smartphone-based devices with conventional PTA as a reference test. A bivariate random-effects meta-analysis was performed to estimate the pooled sensitivity and specificity. The factors associated with diagnostic accuracy were identified using a bivariate meta-regression model. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool.

Results

In all, 25 studies with a total of 4470 patients were included in the meta-analysis. The overall sensitivity, specificity, and area under the receiver operating characteristic curve for smartphone-based audiometry were 89% (95% CI 83%-93%), 93% (95% CI 87%-97%), and 0.96 (95% CI 0.93-0.97), respectively; the corresponding values for the smartphone-based speech recognition test were 91% (95% CI 86%-94%), 88% (95% CI 75%-94%), and 0.93 (95% CI 0.90-0.95), respectively. Meta-regression analysis revealed that patient age, equipment used, and the presence of soundproof booths were significantly related to diagnostic accuracy.

Conclusions

We have presented comprehensive evidence regarding the effectiveness of smartphone-based tests in diagnosing hearing loss. Smartphone-based audiometry may serve as an accurate and accessible approach to hearing evaluations, especially in settings where conventional PTA is unavailable.

Barriers and facilitators to delivery of group audiological rehabilitation programs: a survey based on the COM-B model

OBJECTIVE

To canvas the views of Australia-based hearing healthcare clinicians regarding group audiological rehabilitation practices.

DESIGN

A national cross-sectional self-report survey. Data were analysed using descriptive statistics and content analysis.

STUDY SAMPLE

Sixty-two Australia-based hearing healthcare clinicians, with experience working in an adult rehabilitation setting.

RESULTS

Clinicians appeared to positively view the provision of group audiological rehabilitation services, yet were limited in their ability to deliver these services due to organisational barriers. Although some organisational barriers were non-modifiable by the clinician (such as group AR services not prioritised within their workplace, a lack of support from colleagues/managers, lack of resources, and a lack of funding for the delivery of group AR services), others were within the clinicians' ability to change (such as habit formation for recommending these services during clinical appointments). Participants expressed a desire for resources to assist them in delivering group AR, including downloadable lesson plans and information sheets for clients, clinician training videos and client educational videos. Clinicians called for increased diversity in program offerings, specifically relating to the emotional, relational and social impacts of hearing loss.

CONCLUSIONS

These results provide a framework for the development of interventional studies to increase the utilisation of group audiological rehabilitation services.

Understanding patient empowerment along the hearing health journey

OBJECTIVE

Related to the hearing health journey, this study aimed to: (i) explore how empowerment manifests itself from individuals' first awareness of hearing loss through to hearing aid fitting and then to becoming an active hearing aid user, (ii) identify points when the different dimensions of empowerment are most relevant, and (iii) conceptualise empowerment.

DESIGN

A semi-structured interview study was conducted, followed by a template analysis of the data.

STUDY SAMPLE

Adult hearing aid users from Sweden (n = 8) and Australia (n = 10) who had worn hearing aids for between 6 and 36 months.

RESULTS

The themes that emerged from the transcripts were knowledge, skills and strategies, participation, self-efficacy, and control.

CONCLUSIONS

This study conceptualises empowerment along the hearing health journey as the process through which individuals with hearing-related challenges acquire and use knowledge, skills, and strategies, and increase self-efficacy, participation, and the feeling of control of their hearing health care, hearing solutions, and everyday lives. There are not specific points along the hearing health journey where any dimension is uniquely relevant, instead, each dimension is a dynamic component at all stages.

The association between non-communicable disease and hearing aid adoption in older adults with hearing loss

Objective: To assess whether specific non-communicable diseases are associated with hearing aid adoption in older adults with hearing loss.Design: A cross-sectional, observational study.Study sample: Data was obtained from one of the largest pharmacy-led health and beauty retailers in the United Kingdom. In total, 17,172 older adults were included.Results: Greater odds of adopting hearing aids were associated with being older (Odds ratio [OR] = 1.03; 95% confidence interval [CI] = 1.02, 1.03), having fewer self-reported hearing difficulties (OR = 0.61; 95% CI = 0.58, 0.64), and greater audiometric hearing loss (OR = 1.68; 95% CI = 1.54, 1.83). The odds of adopting hearing aids were lower if individuals self-reported hypertension (OR = 0.87; 95% CI = 0.79, 0.97) and diabetes (OR = 0.83; 95% CI = 0.72, 0.95). Using a decision tree model, self-reported hearing difficulties, audiometric hearing loss, and age were the best combination of variables to differentiate between individuals that did and did not adopt hearing aids.Conclusions: This study demonstrates that hearing aid adoption is lower in older adults with cardiovascular disease risk factors. Thus, there is a need for healthcare professionals to identify older adults living with hearing loss and cardiovascular ill-health, ensuring that they receive appropriate patient-centred support to manage their health.

The feasibility of an m-health educational programme (m2Hear) to improve outcomes in first-time hearing aid users

OBJECTIVE

To (i) assess the delivery, accessibility, usability, acceptability, and adherence, and (ii) identify suitable outcome measures, for a mobile-enhanced multimedia educational programme (m2Hear) in first-time hearing aid users.

DESIGN

A prospective, single-centre feasibility study.

STUDY SAMPLE

First-time hearing aid users (n = 59), recruited at their initial hearing assessment. Evaluations were made at 1-week and at 10-12 weeks post-hearing aid fitting.

RESULTS

m2Hear was most commonly accessed via tablets (42.3%). Usability was high for the System Usability Scale (88.5%), and the uMARS, particularly for the Information (M = 4.7), Functionality (M = 4.5) and Aesthetics (M = 4.2) subscales (maximum score = 5). Participant feedback was positive, with a high percent agreeing that m2Hear aided understanding of hearing aids (98%), held their interest (86%), improved confidence to use hearing aids and communicate (84%), and provided additional information to audiologist's advice (82%). Learnings about practical hearing aid handling/maintenance skills and how to communicate with others were reportedly used equally in participant's everyday lives. m2Hear was convenient to use, clear, concise and comprehensive. Outcome measures of social participation resulted in large effect sizes (Cohen's d > 1.6).

CONCLUSIONS

A theoretically-driven, personalised and co-designed educational m-health intervention is feasible and beneficial for use in the self-management of hearing loss and hearing aids.

Using smartphone technology to support the adult audiologic rehabilitation journey

OBJECTIVE

Although the availability of mobile device applications (apps) to support people with hearing impairment is rapidly increasing, there are few reports of the use of such apps by the target population. The aim of this paper is to describe research that has applied apps at various stages of the adult rehabilitation journey.

DESIGN

A summary of studies utilising apps to investigate (1) the hearing difficulties and acoustic environments of adults with mild hearing impairment, (2) hearing aid benefit in this population and (3) useability of an app to guide hearing aid handling tasks.

STUDY SAMPLE

Older adults with no previous experience with hearing aids, who owned a smartphone or tablet and were confident in using apps. Participant samples ranged from 10 (hearing aid benefit pilot study, mean age = 70 years) to 30 participants (app useability study, mean age = 69 years).

RESULTS

All studies showed that smartphone apps can provide real-world insights during the early stages of the patient journey and hearing aid management support during the latter stages. App useability was rated positively by participants.

CONCLUSION

Smartphone apps may be used as a feasible complement to face-to-face interaction in audiology practice.

Identifying the approaches used by audiologists to address the psychosocial needs of their adult clients

OBJECTIVE

To identify the approaches taken by audiologists to address their adult clients' psychosocial needs related to hearing loss.

DESIGN

A participatory mixed methods design. Participants generated statements describing the ways in which the psychosocial needs of their adult clients with hearing loss are addressed, and then grouped the statements into themes. Data were obtained using face-to-face and online structured questions. Concept mapping techniques were used to identify key concepts and to map each of the concepts relative to each other.

STUDY SAMPLE

An international sample of 65 audiologists.

RESULTS

Ninety-three statements were generated and grouped into seven conceptual clusters: Client Empowerment; Use of Strategies and Training to Personalise the Rehabilitation Program; Facilitating Peer and Other Professional Support; Providing Emotional Support; Improving Social Engagement with Technology; Including Communication Partners; and Promoting Client Responsibility.

CONCLUSIONS

Audiologists employ a wide range of approaches in their attempt to address the psychosocial needs associated with hearing loss experienced by their adult clients. The approaches described were mostly informal and provided in a non-standardised way. The majority of approaches described were not evidence-based, despite the availability of several options that are evidence-based, thus highlighting the implementation gap between research and clinical practice.
