Consumer and audiologist perspectives on hearables: a qualitative study.

OBJECTIVE: We aimed to explore (i) what adults with hearing difficulties want and need from hearables, which we defined as any non-medical personal sound amplification product, and (ii) what hearing care professionals think about hearables. DESIGN: This was an exploratory, qualitative study conducted using separate focus groups with adults with hearing difficulties and audiologists. Data were analysed inductively using reflexive thematic analysis. STUDY SAMPLE: Participants were 12 adults with hearing difficulties and 6 audiologists. RESULTS: Adults with hearing difficulties expressed desire for trustworthy information and support, described evaluating hearables and other devices according to diverse personal criteria, and expressed willingness to vary their budget according to product quality. Audiologists expressed views that hearables are an inferior product but useful tool, that it is not necessarily their role to assist with hearables, that hearables are a source of uncertainty, and that the provision of hearables by audiologists is not currently practical. CONCLUSION: Adults with hearing difficulties may have complex reasons for considering hearables and may desire a high level of clinical support in this area. Ongoing research into the efficacy and effectiveness of hearables is needed together with research into effective strategies to incorporate hearables into clinical practice.

What's in a name? A systematic review and meta-analysis to assess the effectiveness of non-medical amplification devices in adults with mild and moderate hearing losses.

OBJECTIVE: To assess non-medical amplification devices in adults with mild-to-moderate hearing loss, and the impact of device features on outcomes. DESIGN: A prospectively registered systematic review. STUDY SAMPLE: Ten studies evaluating personal sound amplification products (PSAPs), and four evaluating smartphone amplification applications (or apps). Devices were classified as "premium" or "basic" based on the number of compression channels (≥16 or <16, respectively). RESULTS: Meta-analyses showed that premium PSAPs improved speech intelligibility in noise performance compared to unaided, whereas basic PSAPs and smartphone apps did not. Premium PSAPs performed better than basic hearing aids. Premium hearing aids performed better than premium and basic PSAPs, smartphone apps, and basic hearing aids. Although data could not be pooled, similar findings were also found for quality of life, listening ability, cognition, feasibility, and adverse effects. CONCLUSIONS: Premium PSAPs appear to be an effective non-medical amplification device for adults with mild-to-moderate hearing loss. Given the overlap in features available, it may be that this is a key consideration when drawing comparisons between devices, rather than the device being named a PSAP or hearing aid. Nevertheless, the extent to which PSAPs are effective without audiological input remains to be determined.

Clinical Assessment Tools for the Detection of Cognitive Impairment and Hearing Loss in the Ageing Population: A Scoping Review.

Objective: There is a strong association between cognitive impairment and hearing loss, both highly prevalent in the ageing population. Early detection of both hearing loss and cognitive impairment is essential in the management of these conditions to ensure effective and informed decisions on healthcare. The main objective was to identify existing and emerging cognitive and auditory assessment tools used in clinical settings (eg, memory clinics, audiology clinics), which manage the ageing population. Methods: A scoping review of peer-reviewed publications and results were reported according to the PRISMA-ScR guidelines. Results: A total of 289 articles were selected for data extraction. The majority of studies (76.1%) were conducted in 2017 or later. Tests of global cognitive function (ie, Mini-Mental State Exam, Montreal Cognitive Assessment) were the most commonly used method to detect cognitive impairment in hearing healthcare settings. Behavioral hearing testing (ie, pure-tone audiometry) was the most commonly used method to detect hearing loss in cognitive healthcare settings. Objective, physiological measures were seldom used across disciplines. Conclusion: Preferences among clinicians for short, accessible tests likely explain the use of tests of global cognitive function and behavioral hearing tests. Rapidly evolving literature has identified inherent limitations of administering global cognitive function tests and pure-tone testing in an ageing population. Using electrophysiological measures as an adjunct to standard methods of assessment may provide more reliable information for clinical recommendations in those with cognitive and hearing impairment, and subsequently achieve better healthcare outcomes.

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.

Evaluation of home-delivered live-voice auditory training for adult hearing aid users involving their communication partners: a randomised controlled trial.

OBJECTIVE: To examine the benefits of home-delivered auditory training for adult hearing aid users using live-voice conversations in the presence of a single-talker distractor (experimental group) or in quiet (active-control group). DESIGN: Randomised controlled trial. The experimental group held conversations with their nominated communication partner in the presence of a single-talker distractor set to a challenging level, 30 min/day, 5 days/week over 4 weeks. The active-control group held comparable conversations in quiet. Behavioural outcome measures of speech-in-noise perception, cognition and self-reported hearing difficulties were assessed pre- and post-training. Participant feedback was obtained. STUDY SAMPLE: Thirty-nine hearing aid users (32 males, 7 females, mean age = 73.02 years, SD = 4.71 years) and their communication partners. RESULTS: The experimental group significantly improved and outperformed the active-control group for words-in-noise perception. Both groups achieved improvements in self-reported hearing difficulty while only the experimental group improved on dual-task. Subjectively, both groups found live-voice conversations beneficial and reported increased concentration and listening skills. CONCLUSIONS: Home-delivered live-voice auditory training with communication partners shows potential to improve outcomes for adult hearing aid users, regardless of the presence or absence of a competing speech distractor. Further research is required to assess mechanisms of benefit and distractor effects within carefully controlled experiments.

A qualitative study showing that a telecare tool can have benefits before and during the initial hearing assessment appointment.

OBJECTIVE: To examine patient and audiologist experiences and perspectives of using a patient-centred telecare tool, the Ida Institute's Why Improve My Hearing? (WIMH) Tool, before and during the initial hearing assessment appointment. DESIGN: A qualitative study comprising individual semi-structured interviews using a maximum variation sampling strategy. The data were analysed using an established thematic analysis technique. STUDY SAMPLE: Fifteen participants, including ten patients (i.e. adults with hearing loss) and five audiologists, were recruited from Adult Audiology Services within the United Kingdom's publicly-funded National Health Service (NHS). RESULTS: Three themes described the impact of using the WIMH Tool. Theme 1 (i.e. enhanced preparation before the appointment): the Tool helps patients to better understand and accept their hearing difficulties in advance of their first appointment. Theme 2 (i.e. enriched discussion during the appointment): the tool can enhance patient-centred communication, as well as the efficiency of the appointment. Theme 3 (i.e. varied impact on outcomes following the appointment): the Tool can improve patient motivation, readiness, and involvement in decision-making, though it may have limited impact on additional outcomes, such as adherence. CONCLUSION: The WIMH Tool can be successfully implemented in audiological practice, resulting in benefits before and during the initial hearing assessment appointment.

Smartphone-Connected Hearing Aids Enable and Empower Self-Management of Hearing Loss: A Qualitative Interview Study Underpinned by the Behavior Change Wheel.

OBJECTIVES: To identify patient-reported barriers and facilitators to using smartphone-connected hearing aids, using the Behavior Change Wheel (BCW) to understand experiences and how these can be addressed. DESIGN: A single-center, prospective, observational study. Eight hearing aid users (new = 1, existing = 7; mean age = 71.75 years, SD = 5.23, range = 65 to 81 years) were identified through convenience sampling from 44 participants who took part in a 7-week evaluation of smartphone-connected hearing aids controlled by a prototype app. The app allowed users to manually control settings such as gain, noise reduction, and microphone directionality, preset, and customized programmes. Participants were assigned to one of two focus groups following trial of the app. RESULTS: Focus group transcripts were thematically analyzed and underpinned by the COM-B (Capability, Opportunity, Motivation-Behavior) model and Theoretical Domains Framework to identify barriers and facilitators to using smartphone-connected hearing aids (the target behavior). Mapping of themes to the BCW allowed use of the Behavior Change Technique Taxonomy (version 1) to identify behavior change techniques that audiologists could implement in clinical practice to address the barriers and facilitators. Capability: The app increased participants' knowledge of hearing aid controls, encouraging use of the app for improved hearing loss self-management. However, barriers to using the app included perception of insufficient digital literacy skills for smartphone-connected hearing aid use and an increased cognitive load caused by decisions over which controls to use. Opportunity: Perceived smartphone norms (i.e., acceptable occasions to use smartphones) and differing listening contexts acted as both facilitators and barriers. Motivation: The ability to control hearing aid settings in any listening situation (e.g., to reduce noise) empowered users to successfully self-manage their hearing loss, leading to greater confidence and participation in everyday life. The app also reduced hearing aid-related and self-stigma, and the ability to self-adjust hearing aids benefitted both participants and communication partners. It was the adjustability and interaction afforded by the app that empowered users, rather than the hearing aid technology itself. Perceived beliefs and knowledge about digital literacy skills, and specifically abilities to use a smartphone, were perceived to be barriers in this typically older population, particularly when they compared themselves to younger generations. Using the Behavior Change Technique Taxonomy (version 1), behavior change techniques that could be used by audiologists to address these barriers included enablement, goal setting, reframing perceptions toward technology, and addressing patient educational needs. CONCLUSIONS: Smartphone-connected hearing aids, when used in their everyday lives, were viewed positively by participants across a range of domains, empowering them and enabling hearing loss self-management. Audiologists should consider smartphone-connected hearing aid candidacy for all who have access to smartphones and are willing to use one. Use of the BCW has identified that modifiable barriers to using smartphone-connected hearing aids exist. Audiologists could use these evidence-based behavior change techniques to support patients in adopting and using these technologies to successfully self-manage hearing loss. Overall, by reframing smartphone technologies as a tool to remain connected with society, smartphone-connected hearing aids could shift the power of managing hearing loss from clinician to patient.

Consensus on connected hearing health technologies and service delivery models in the UK: a Delphi review.

OBJECTIVE: To develop a consensus among hearing healthcare professionals in the UK on connected hearing health technologies and service delivery models. DESIGN: A three-round, electronic Delphi review was developed using a participatory-design approach. This included ten open-ended questions (round one) that informed 69 Likert-scaled statements (rounds two and three). STUDY SAMPLE: An expert panel of 34 hearing health professionals representing all geographic regions of the UK from either the publicly funded National Health Service (n = 22) or independent sector (n = 12). RESULTS: The majority of statements (61%) showed ≥80% consensus, highlighting that there was broad agreement amongst professionals on connected hearing health technologies. For example, there was consensus that adults who report communication difficulties and have no medical contraindications would be ideal candidates. Furthermore, it was unanimously agreed that connected technologies could result in delays in diagnosis of treatable medical conditions, as well as result in inadequate amplification. Overall, the expert panel concurred that connected technologies could serve as "gateway products" that lead to earlier hearing aid uptake. CONCLUSIONS: This Delphi review identified overarching areas of agreement that may serve as a blueprint for future implementation of connected hearing health technologies through either conventional or new service delivery models in the UK.

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.

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

BACKGROUND: Adults living with hearing loss have highly variable knowledge of hearing aids, resulting in suboptimal use or nonuse. This issue can be addressed by the provision of high-quality educational resources. OBJECTIVE: This study aims to assess the everyday experiences of first-time hearing aid users when using a newly developed, theoretically informed cocreated mobile health (mHealth) educational intervention called m2Hear. This intervention aims to deliver greater opportunities for individualization and interactivity compared with our previously developed multimedia intervention, C2Hear. METHODS: A total of 16 first-time hearing aid users trialed m2Hear for a period of 10-weeks in their everyday lives, after which individual semistructured interviews were completed. The data were analyzed using an established deductive thematic analysis procedure underpinned by the Capability, Opportunity, Motivation-Behavior model. The model stipulates that to engage in a target behavior, an individual must have physical and psychological capability, physical and social opportunity, and automatic and reflective motivation. RESULTS: Capability-m2Hear was viewed as a concise and comprehensive resource, suitable for a range of digital literacy skills. It was stated that m2Hear could be conveniently reused to provide useful reminders that facilitate knowledge of hearing aids and communication. Opportunity-m2Hear was simple and straightforward to use, enabling greater individualization and independence. The availability of m2Hear via mobile technologies also improved accessibility. Motivation-m2Hear provided greater support and reassurance, improving confidence and empowering users to self-manage their hearing loss. CONCLUSIONS: Overall, this qualitative study suggests that m2Hear supports first-time hearing aid users to successfully self-manage their hearing loss postfitting. Furthermore, this study demonstrates the utility of employing a combined theoretical and ecologically valid approach in the development of mHealth educational resources to meet the individual self-management needs of adults living with hearing loss. TRIAL REGISTRATION: ClinicalTrials.gov NCT03136718; https://clinicaltrials.gov/ct2/show/NCT03136718.

The development of an mHealth educational intervention for first-time hearing aid users: combining theoretical and ecologically valid approaches.

Objective: This paper describes the development of a novel mobile health (mHealth) educational intervention, called m2Hear, designed for first-time hearing aid users based on previously developed educational multimedia videos, or reusable learning objects (RLOs), branded C2Hear.Design: The development of m2Hear used theoretical and ecologically valid approaches. The COM-B model and associated Theoretical Domains Framework were employed to identify specific components (or "active ingredients") of the original RLOs that facilitate hearing aid use. An mHealth platform was then developed following an iterative, user-centred and participatory design approach.Study sample: Fifteen existing hearing aid users completed synchronous, real-time Think Aloud interviews. A sub-group of these participants (n = 5), along with patient and public involvement panel members (n = 4), subsequently reviewed the usability of the mHealth platform.Results: While factors associated with Capability featured strongly across all RLOs, topics relating to Opportunity and Motivation were also incorporated. The RLOs were broken-down into 42 shorter mobile-enhanced RLOs (or mRLOs). Each mRLO was labelled with a specific user-centred question generated from the Think Aloud interviews. The final mHealth platform was developed following four separate usability iterations.Conclusions: Overall, m2Hear provides greater opportunities for individualised learning and encourages greater interaction to facilitate self-management in first-time hearing aid users.

Application of Rasch Analysis to the Evaluation of the Measurement Properties of the Hearing Handicap Inventory for the Elderly.

OBJECTIVES: The aim of this research was to evaluate the measurement properties of the Hearing Handicap Inventory for the Elderly (HHIE). The HHIE is one of the most widely used patient-reported outcome measures in audiology. It was originally developed in the United States in the 1980s as a measure of the social and emotional impact of hearing loss in older adults. It contains 25 items that are accompanied by a 3-point response scale. To date, the measurement properties of the HHIE have primarily been assessed via traditional psychometric analysis techniques (e.g., Cronbach's alpha and Principal Components Analysis). However, traditional techniques are now known to have several limitations in comparison to more modern approaches. Therefore, this research used a modern psychometric analysis technique, namely Rasch analysis, to evaluate the HHIE. DESIGN: Rasch analysis was performed on HHIE data collected from 380 adults with hearing loss. The participants were principally recruited from the participant database of the National Institute for Health Research Nottingham Biomedical Research Centre in the United Kingdom. Additional participants were recruited from two UK audiology clinics and the online forum of a UK hearing loss charity. Rasch analysis was used to assess the measurement properties of the HHIE (i.e., fit to the Rasch model, unidimensionality, targeting, and person separation reliability) and its individual items (i.e., response dependency, fit, Differential Item Functioning, and threshold ordering). RESULTS: The HHIE was found to have several strong measurement properties. Specifically, it was well-targeted and had high person separation reliability. However, it displayed poor fit to the Rasch model and was not unidimensional. The majority of the items were free of response dependency (i.e., redundancy) and were suited to the 3-point response scale. However, two items were found to be better suited to a dichotomous response scale. Furthermore, nine items were identified as being candidates for removal from the questionnaire, as they exhibited poor fit and/or Differential Item Functioning (i.e., item bias) associated with gender. The measurement properties of the HHIE could be improved by removing these items and adjusting the scores of the two items that require a dichotomous response scale. These amendments resulted in a 16-item version of the HHIE that had good fit to the Rasch model and that was unidimensional. CONCLUSIONS: It is vital to ensure that high-quality outcome measures are used in audiology research and practice. This study evaluated one of the foremost outcome measures in this field: the HHIE. The results demonstrated that the HHIE had several strong measurement properties. Amending the HHIE, such as by removing items exhibiting poor fit, could further enhance its quality. A unique aspect of this study was the application of Rasch analysis to the evaluation of the HHIE. It is recommended that future studies use modern techniques to develop and identify high-quality, hearing-specific outcome measures.

Minimal and Mild Hearing Loss in Children: Association with Auditory Perception, Cognition, and Communication Problems.

OBJECTIVES: "Minimal" and "mild" hearing loss are the most common but least understood forms of hearing loss in children. Children with better ear hearing level as low as 30 dB HL have a global language impairment and, according to the World Health Organization, a "disabling level of hearing loss." We examined in a population of 6- to 11-year-olds how hearing level ≤40.0 dB HL (1 and 4 kHz pure-tone average, PTA, threshold) is related to auditory perception, cognition, and communication. DESIGN: School children (n = 1638) were recruited in 4 centers across the United Kingdom. They completed a battery of hearing (audiometry, filter width, temporal envelope, speech-in-noise) and cognitive (IQ, attention, verbal memory, receptive language, reading) tests. Caregivers assessed their children's communication and listening skills. Children included in this study (702 male; 752 female) had 4 reliable tone thresholds (1, 4 kHz each ear), and no caregiver reported medical or intellectual disorder. Normal-hearing children (n = 1124, 77.1%) had all 4 thresholds and PTA <15 dB HL. Children with ≥15 dB HL for at least 1 threshold, and PTA <20 dB (n = 245, 16.8%) had minimal hearing loss. Children with 20 ≤PTA <40 dB HL (n = 88, 6.0%) had mild hearing loss. Interaural asymmetric hearing loss ( left PTA - right PTA ≥10 dB) was found in 28.9% of those with minimal and 39.8% of those with mild hearing loss. RESULTS: Speech perception in noise, indexed by vowel-consonant-vowel pseudoword repetition in speech-modulated noise, was impaired in children with minimal and mild hearing loss, relative to normal-hearing children. Effect size was largest (d = 0.63) in asymmetric mild hearing loss and smallest (d = 0.21) in symmetric minimal hearing loss. Spectral (filter width) and temporal (backward masking) perceptions were impaired in children with both forms of hearing loss, but suprathreshold perception generally related only weakly to PTA. Speech-in-noise (nonsense syllables) and language (pseudoword repetition) were also impaired in both forms of hearing loss and correlated more strongly with PTA. Children with mild hearing loss were additionally impaired in working memory (digit span) and reading, and generally performed more poorly than those with minimal loss. Asymmetric hearing loss produced as much impairment overall on both auditory and cognitive tasks as symmetric hearing loss. Nonverbal IQ, attention, and caregiver-rated listening and communication were not significantly impaired in children with hearing loss. Modeling suggested that 15 dB HL is objectively an appropriate lower audibility limit for diagnosis of hearing loss. CONCLUSIONS: Hearing loss between 15 and 30 dB PTA is, at ~20%, much more prevalent in 6- to 11-year-old children than most current estimates. Key aspects of auditory and cognitive skills are impaired in both symmetric and asymmetric minimal and mild hearing loss. Hearing loss <30 dB HL is most closely related to speech perception in noise, and to cognitive abilities underpinning language and reading. The results suggest wider use of speech-in-noise measures to diagnose and assess management of hearing loss and reduction of the clinical hearing loss threshold for children to 15 dB HL.

Effects of Cognitive Load on Pure-Tone Audiometry Thresholds in Younger and Older Adults.

OBJECTIVES: Cognitive load (CL) impairs listeners' ability to comprehend sentences, recognize words, and identify speech sounds. Recent findings suggest that this effect originates in a disruption of low-level perception of acoustic details. Here, we attempted to quantify such a disruption by measuring the effect of CL (a two-back task) on pure-tone audiometry (PTA) thresholds. We also asked whether the effect of CL on PTA was greater in older adults, on account of their reduced ability to divide cognitive resources between simultaneous tasks. To specify the mechanisms and representations underlying the interface between auditory and cognitive processes, we contrasted CL requiring visual encoding with CL requiring auditory encoding. Finally, the link between the cost of performing PTA under CL, working memory, and speech-in-noise (SiN) perception was investigated and compared between younger and older participants. DESIGN: Younger and older adults (44 in each group) did a PTA test at 0.5, 1, 2, and 4 kHz pure tones under CL and no CL. CL consisted of a visual two-back task running throughout the PTA test. The two-back task involved either visual encoding of the stimuli (meaningless images) or subvocal auditory encoding (a rhyme task on written nonwords). Participants also underwent a battery of SiN tests and a working memory test (letter number sequencing). RESULTS: Younger adults showed elevated PTA thresholds under CL, but only when CL involved subvocal auditory encoding. CL had no effect when it involved purely visual encoding. In contrast, older adults showed elevated thresholds under both types of CL. When present, the PTA CL cost was broadly comparable in younger and older adults (approximately 2 dB HL). The magnitude of PTA CL cost did not correlate significantly with SiN perception or working memory in either age group. In contrast, PTA alone showed strong links to both SiN and letter number sequencing in older adults. CONCLUSIONS: The results show that CL can exert its effect at the level of hearing sensitivity. However, in younger adults, this effect is only found when CL involves auditory mental representations. When CL involves visual representations, it has virtually no impact on hearing thresholds. In older adults, interference is found in both conditions. The results suggest that hearing progresses from engaging primarily modality-specific cognition in early adulthood to engaging cognition in a more undifferentiated way in older age. Moreover, hearing thresholds measured under CL did not predict SiN perception more accurately than standard PTA thresholds.

Applying the COM-B Model to Assess the Usability of Smartphone-Connected Listening Devices in Adults with Hearing Loss.

BACKGROUND: Unlike conventional hearing aids, smartphone-connected listening devices may require limited or no input from a trained audiologist in terms of device programming and adjustment. However, there is a lack of peer-reviewed evidence assessing the real-world perspectives of people living with hearing loss toward such technological innovations. PURPOSE: This study assessed the everyday experiences of adults living with hearing loss toward a range of smartphone-connected listening devices using the Capability, Opportunity, Motivation, Behaviour (COM-B) model as a theoretical framework. RESEARCH DESIGN: A qualitative study where participants trialed one of the following smartphone-connected listening devices for two weeks in their everyday lives: made-for-smartphone hearing aid, personal sound amplification product, and smartphone "hearing aid" app with wired earphones or wireless hearable. Individual semistructured interviews were conducted. STUDY SAMPLE: Twenty adults (13 male and 7 female; mean age = 62.25 years, SD = 11.59) with mild-to-moderate hearing loss (mean better ear pure-tone average = 30.49 dB HL, SD = 17.51) were recruited using a convenience sampling strategy. All participants owned conventional hearing aids. DATA ANALYSIS: The data were analyzed using an established deductive thematic analysis procedure within the context of the COM-B model. The model stipulates that for individuals to engage in a particular behavior (B), they must have sufficient capability (C), opportunity (O), and motivation (M). RESULTS: Capability: One of the key advantages facilitating use and adherence of smartphone-connected listening devices was the ability for participants to make fine-tune adjustments in any listening situation. Opportunity: Participants commented that these devices could address issues surrounding stigma as smartphones are ubiquitous in everyday life. Motivation: Participants consistently reported that the ability to make adjustments via a smartphone provided them with a greater sense of autonomy and empowerment. As a result, they felt more in control of their hearing loss. CONCLUSIONS: This study lays the foundation for further high-quality research to explore whether smartphone-connected technologies have the potential to yield optimum benefits for people living with hearing loss.

A simple method to estimate noise levels in the workplace based on self-reported speech communication effort in noise.

Objective: To validate a method using self-reported speech communication effort in noise to estimate occupational noise levels by comparing with measured noise levels. Design: A comparative observational study. Reported vocal effort to communicate with a person at a distance of 1.2 m during workplace-related tasks was used to provide an estimate of noise levels in the workplace. These estimated noise levels were compared against noise level measurements obtained using personal noise dosimetry badges for corresponding tasks undertaken by participants. Study sample: Participants (n = 168) aged 16-25 years were recruited from companies where workplace noise levels were at least 85 dB(A). Results: Estimated noise levels using speech communication ability were evenly distributed above and below the measured noise levels (n = 134), indicating a lack of systematic bias in the method. For 91% of participants, estimates of noise levels using speech communication were within ±6 dB of the measured levels, whilst 56% were within ±3 dB. Conclusions: Report of speech communication effort required in noise by employees is an effective method of estimating noise levels within the workplace. This can be used for retrospective noise level assessment where there are no recorded noise level measurements, such as for retrospective research studies or in medicolegal work.

Refinement and Validation of the Social Participation Restrictions Questionnaire: An Application of Rasch Analysis and Traditional Psychometric Analysis Techniques.

OBJECTIVES: The primary aim of this research was to refine and validate the Social Participation Restrictions Questionnaire (SPaRQ). The SPaRQ is a hearing-specific, patient-reported outcome measure that was originally developed through consultation with adults with hearing loss, clinicians, and researchers. This research comprised two studies. Study 1 aimed to assess the psychometric properties of the SPaRQ and to improve these properties by amending the questionnaire (e.g., removing items) as required. Study 2 aimed to validate the refined SPaRQ. DESIGN: In study 1, 279 adults with hearing loss completed a long-form, 53-item SPaRQ. Rasch analysis, a modern psychometric analysis technique, was used to assess a range of psychometric properties for the questionnaire (e.g., unidimensionality, fit to the Rasch model). The properties of the individual items were also assessed (e.g., response dependency, differential item functioning). In study 2, 102 adults with hearing loss completed the refined SPaRQ. In addition, they completed three questionnaires that had been designed to measure related constructs. These were a hearing-specific questionnaire (Hearing Handicap Inventory for the Elderly), a generic health and disability questionnaire (shortened World Health Organization Disability Assessment Schedule 2.0), and a brief depression and anxiety screening questionnaire (Patient Health Questionnaire-4). Traditional psychometric analysis techniques (e.g., Cronbach's alpha) were used to assess the construct validity and internal consistency of the refined SPaRQ. RESULTS: Rasch analysis was used to refine the SPaRQ. The result was a 19-item measure divided into two subscales. The 9-item Social Behaviors subscale measured difficulties with performing actions in a social context due to hearing loss. The 10-item Social Perceptions subscale measured negative thoughts and feelings experienced in a social context due to hearing loss. Both Rasch analysis and the traditional psychometric analysis techniques demonstrated that each subscale had strong psychometric properties. In particular, each subscale passed the test of unidimensionality, displayed good fit to the Rasch model, and had high internal consistency. In addition, it was found that, as predicted, each subscale had strong, positive correlations with the hearing-specific questionnaire and moderate, positive correlations with the generic health and disability questionnaire and the depression and anxiety screening questionnaire. Taken together, these findings support the construct validity of the 19-item SPaRQ. CONCLUSIONS: This was one of the first studies to devise a new hearing-specific outcome measure using Rasch analysis. Rasch analysis proved to be a powerful technique for supporting decisions regarding which items to retain in order to achieve a psychometrically robust questionnaire. Additional support for the robustness of this questionnaire came from the utilization of traditional psychometric analysis techniques. Therefore, this questionnaire has the potential to be used in research and clinical practice to evaluate whether auditory rehabilitation interventions improve social participation in adults with hearing loss. The next stage of this research will be to further validate this questionnaire by assessing its responsiveness in a clinical population. The combined use of modern and traditional psychometric analysis techniques should be considered in future questionnaire development and validation research.

A systematic review and meta-analysis assessing the effectiveness of alternative listening devices to conventional hearing aids in adults with hearing loss.

Recent technological advances have led to a rapid increase in alternative listening devices to conventional hearing aids. The aim was to systematically review the existing evidence to assess the effectiveness of alternative listening devices in adults with mild and moderate hearing loss. A systematic search strategy of the scientific literature was employed, reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) checklist. Eleven studies met eligibility for inclusion: two studies evaluated personal sound amplification products, and nine studies assessed remote microphone systems (frequency modulation, Bluetooth, wireless). The evidence in this review suggests that alternative listening devices improve behavioural measures of speech intelligibility relative to unaided and/or aided conditions. Evidence for whether alternative listening devices improve self-reported outcomes is inconsistent. The evidence was judged to be of poor to good quality and subject to bias due to limitations in study design. Our overall recommendation is that high-quality evidence (i.e. randomised controlled trials) is required to demonstrate the effectiveness of alternative listening devices. Such evidence is not currently available and is necessary to guide healthcare commissioners and policymakers when considering new service delivery models for adults with hearing loss.

Auditory and Cognitive Training for Cognition in Adults With Hearing Loss: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis examined the efficacy of auditory training and cognitive training to improve cognitive function in adults with hearing loss. A literature search of academic databases (e.g., MEDLINE, Scopus) and gray literature (e.g., OpenGrey) identified relevant articles published up to January 25, 2018. Randomized controlled trials (RCTs) or repeated measures designs were included. Outcome effects were computed as Hedge's g and pooled using random-effects meta-analysis (PROSPERO: CRD42017076680). Nine studies, five auditory training, and four cognitive training met the inclusion criteria. Following auditory training, the pooled effect was small and statistically significant for both working memory ( g = 0.21; 95% CI [0.05, 0.36]) and overall cognition ( g = 0.19; 95% CI [0.07, 0.31]). Following cognitive training, the pooled effect for working memory was small and statistically significant ( g = 0.34; 95% CI [0.16, 0.53]), and the pooled effect for overall cognition was large and significant ( g = 1.03; 95% CI [0.41, 1.66]). However, this was dependent on the classification of training approach. Sensitivity analyses revealed no statistical difference between the effectiveness of auditory and cognitive training for improving cognition upon removal of a study that used a combined auditory-cognitive approach, which showed a very large effect. Overall certainty in the estimation of effect was "low" for auditory training and "very low" for cognitive training. High-quality RCTs are needed to determine which training stimuli will provide optimal conditions to improve cognition in adults with hearing loss.

Development of the Social Participation Restrictions Questionnaire (SPaRQ) through consultation with adults with hearing loss, researchers, and clinicians: a content evaluation study.

OBJECTIVE: This research aimed to evaluate the content of the Social Participation Restrictions Questionnaire (SPaRQ) in terms of its relevance, clarity, comprehensiveness, acceptability to adults with hearing loss, and responsiveness. DESIGN: Cognitive interviews and a subject matter expert survey were conducted. The interview data were analysed using thematic analysis and a taxonomy of questionnaire clarity problems. Descriptive statistics were calculated for the survey data. STUDY SAMPLE: Fourteen adults with hearing loss participated in the cognitive interviews. Twenty clinicians and academics completed the subject matter expert survey. RESULTS: The majority of the SPaRQ content was found to be relevant, clear, comprehensive, and acceptable. However, an important clarity problem was identified: many adults with hearing loss struggled to switch from answering positively worded items (e.g. "I can attend social gatherings") to answering negatively-worded items (e.g. "I feel isolated"). Several subject matter experts found responsiveness difficult to assess. The SPaRQ was amended where necessary. CONCLUSION: Few hearing-specific questionnaires have undergone content evaluation. This study highlights the value of content evaluation as a means of identifying important flaws and improving the quality of a measure. The next stage of this research is a psychometric evaluation of the measure.
