The acquisition of constructions : does modality matter?
(AOSIS, 2024-06-12) Wright, Richenda; Geertsema, Salome; Le Roux, Mia; Winckel, Elodie; Dąbrowska, Ewa
BACKGROUND: Language analytic ability is well researched in the context of foreign language acquisition but its role in the acquisition of grammar in the native language is under investigation. OBJECTIVES: Our study explored the influence of language analytic ability and print exposure on receptive grammar and reading comprehension in childhood. Additionally, we investigated whether exposure to specific constructions through the written modality held an advantage over exposure in the audio modality. METHOD: We assessed the language analytic ability, reading comprehension, reading fluency, print exposure, and receptive grammar of 12-year-olds. Subsequently, we exposed them to written or spoken target constructions, followed by an assessment of receptive grammar. Linear regression models were used to analyse the contributions of reading fluency, print exposure, and language analytic ability to reading comprehension and receptive grammar. We also examined the influence of the intervention on receptive grammar. RESULTS: Language analytic ability and print exposure significantly predicted receptive grammar. Print exposure significantly predicted reading comprehension and improvement in receptive grammar. CONCLUSION: Language analytic ability is important for grammar and reading comprehension development. Print exposure enhances reading comprehension by supporting vocabulary development and providing exposure to intricate structures. Both language analytic ability and experience are key factors in construction acquisition. CONTRIBUTION: This study adds to the growing body of evidence emphasising the role of language analytic skills in native language grammar acquisition and advocates for explicit grammar teaching. Furthermore, it underscores the importance of adequate print exposure in grammar acquisition and the development of reading comprehension skills.
Constant dizziness versus episodic vertigo in Ménière's disease : health-related quality of life, cognitive dissonance, and postural problems
(AVES, 2024-09-24) Pyykko, Ilmari; Zou, Jing; Manchaiah, Vinaya
BACKGROUND : The aim was to explore and characterize dizziness and vertigo (constant vs episodic) and associated problems in patients with Ménière’s disease (MD) to allow characterization of the impact of the disease. METHODS : The study used a retrospective survey design. A total of 539 people with MD participated in this study. The online questionnaire included 36 items which had mixture of structured and open-ended questions that were focusing on MD symptoms, impact of their symptoms, vestibular rehabilitation, as well as health-related quality of life (HRQoL). RESULTS : Forty-six percent of the patients had episodic vertigo, 6% had constant dizziness, 15% had both episodic vertigo and constant dizziness, and 31% did not have vertigo or dizziness within the last 2 years. Patients with MD without any vertigo rated their HRQoL as 73.9%, those with episodic vertigo as 71.1%, those with constant dizziness as 56.9%, and those with constant dizziness and episodic vertigo as 57.9% indicating significant reduction in HRQoL in constant dizziness patients. Constant dizziness was associated with cognitive visual problems, fatigue, balance problems, vestibular drop attacks and syncope. The impact of balance problem was more severe among those with constant dizziness. The most common balance problem was tripping-off (34%), followed by swaying (25%) or rocking (8%) sensations. In the self-administered rehabilitative training, there were no differences between any of the vertigo or dizziness groups although disease profile of MD differed significantly. CONCLUSION : We emphasize that constant dizziness in MD constitutes a long-term maladaptation to a vestibular and visual cognitive function causing cognitive dissonance. Different types of vertigo and their associated complaints require different treatment strategies to the manage balance problems and to cope with the disease, but best practices is still under research.
Diverse phenotype of Ménière's disease associated with family history, thyroid disorder, migraine and associated disorders
(Elsevier, 2024-10) Pyykko, Ilmari; Gupta, Vinay; Zou, Jing; Vetkas, Artur; Manchaiah, Vinaya
OBJECTIVE: To better understand the clinical phenotype of Ménière's disease (MD), we examined family history, thyroid disorder, migraine, and associated disorders in complaints of people living with MD. METHOD: We designed the study as a retrospective and examined data gathered from 912 participants with MD. Their data were originally collected by the Finnish Ménière Federation (FMF). The survey data included individual case histories for environmental factors, comorbidities, disease-specific complaints, impact-related questions, cognitive complaints, health-related quality of life (HRQoL), and sense of coherence (SOC). RESULTS: We observed significant differences between those with and without sporadic occurrence, family history, thyroid disorder, and migraine-associated complaints. Family history explained 20% of variability in patient complaints. Patients with a family history of MD whose disease started at younger age experienced balance problems, more severe vertigo spells, more severe vestibular drop attacks (VDA), and less nausea, although they had good SOC. Thyroid disorder explained 14% of variability in patient complaints. MD patients with a thyroid disorder comorbidity suffered more often from constant dizziness, balance problems, greater impact of hearing problems, cognitive complaints, and poor HRQoL. Migraine explained 12% of variability in patients’ complaints and was associated with poor SOC and cognitive balance problems. MD patients with both thyroid disorder and migraine used antidepressants more often than other groups. Logistic regression analysis showed comorbidities of ischemic brain disorder (among 7.1%), kidney insufficiency (among 1.2%), and diabetes (among 7.3%) had statistically significant but restricted association with balance and gait problems, VDA, and reduced HRQoL. CONCLUSIONS: Family history of MD and thyroid disorder or migraine comorbidities in MD influence the complaint pattern and partially explain complex symptom profiles, including symptoms of cognitive problems. Confounders play a minimal role in complaint profile and impact of MD whereas comorbidities influence the complaint structure and partly explain the complex symptom profile in MD.
Hearing aid benefit in daily life : a qualitative ecological momentary assessment study
(Frontiers Media, 2024-10-09) Fourie, Chane; Mahomed-Asmail, Faheema; Oosthuizen, Ilze; Manchaiah, Vinaya; Vercammen, Charlotte; Swanepoel, De Wet; dewet.swanepoel@up.ac.za
INTRODUCTION : Understanding hearing aid wearer experiences in real-world settings is important to provide responsive and individualized hearing care. This study aimed to describe real-life benefits of hearing aids (HAs), as reported by hearing aid wearers through Ecological Momentary Assessment (EMA) in various listening environments. METHOD : Qualitative content analysis of 1,209 open-text responses, provided through self-initiated EMAs, was conducted. The de-identified data was collected retrospectively via a smartphone app compatible with these HAs. Only text responses reflecting positive hearing aid experiences were analyzed.The 1,209 open-text responses were categorized into 18 pre-determined sub- categories, further organized into five overarching categories: Conversational, Leisure, Device-related aspects, Lifestyle, and Other factors. RESULTS : Across these categories, 48 self-generated meaning units highlighted the multifaceted benefits of HAs. In particular, participants reported significant improvements in conversational settings, specifically during phone conversations and meetings, attributed to improved sound quality and speech understanding when wearing their HAs. During leisure activities, particularly TV watching and music listening, clearer sound and ease of Bluetooth streaming contributed to experienced benefits. Lifestyle improvements were reported in occupational and social settings, as hearing aid wearers stated enhanced communication and sound awareness. Device-related factors contributing to positive wearer experiences included extended battery life and the convenience of rechargeable batteries. The most prominent sub-category, other factors, underscored overall satisfaction, comfort with the device, and improved auditory experiences across various environments. CONCLUSION : This study reveals the diverse benefits of HAs in improving communication, listening experiences, and quality of life across various settings, as captured through EMA. By emphasizing features like direct streaming and rechargeability, the findings highlight the importance of personalized hearing care and the potential of real-time listener feedback to inform device enhancements and support strategies, advancing more tailored and effective hearing rehabilitation.
A novel consumer-centric metric for evaluating hearing device audio performance
(Frontiers Media, 2024-05-27) Manchaiah, Vinaya; Taddei, Steve; Bailey, Abram; Swanepoel, De Wet; Rodrigo, Hansapani; Sabin, Andrew
BACKGROUND AND AIM : The emergence of direct-to-consumer hearing devices has introduced confusion in making appropriate choices, highlighting the need for users to be well-informed for optimal device selection. Currently, no established metric offers insights into the sound performance of these devices. This study aimed to introduce and assess a novel consumer-centric metric (i.e., SoundScore) for hearing device audio performance. METHOD : The SoundScore metric was created based on five dimensions of hearing device audio performance (i.e., speech benefit in quiet and moderate, speech benefit in loud, own voice perception, feedback control, streamedmusic sound quality). Tests were conducted under lab conditions with an acoustic manikin using two fitting protocols meant to approximate (1) real-world default device settings for amild-to-moderate sloping hearing loss (“Initial Fit”) and (2) an audiological best-practices approach (“Tuned Fit”). A total of 41 hearing devices comprising 10 prescription hearing aids (Rx-HA), 10 self-fitting over-the-counter hearing aids (OTC-SF), 8 pre-set based over-the-counter hearing aids (OTC-PS), and 13 personal sound amplification systems (PSAPs) were evaluated. RESULTS : SoundScore varied significantly between device classifications with Rx-HA yielding the highest average scores and PSAPs the lowest. SoundScore also varied with fitting method, whereby preset based devices scored lower on average than devices programmable by fitting software. Performance across the five composite sound performance metrics generally improved between “Initial” and “Tuned” fits for Rx-HA. However, this was not observed with OTC-SF. Also, no significant difference in SoundScore was found between devices of different form factors (i.e., BTE vs. ITE). CONCLUSIONS : Initial findings suggest that the SoundScore can effectively distinguish between the audio performance of different hearing aids, offering consumers a valuable decision-making tool. Future studies should examine the relationship between the SoundScore and consumer hearing aid benefit/satisfaction.
Hearing and functioning in Everyday Life Questionnaire : psychometric evaluation and revision
(American Speech-Language-Hearing Association, 2024-06) Karlsson, Elin; Manchaiah, Vinaya; Maki-Torkko, Elina; Granberg, Sarah; Gustafsson, Johanna; Dahlstrom, Orjan; Widen, Stephen
PURPOSE : The aim of the current study was to explore the construct validity and internal consistency reliability of the International Classification of Functioning, Disability and Health (ICF)–based original English version of the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) and to revise the HFEQ based on the results. METHOD : This study used a cross-sectional survey design. The data were collected using an online survey. Adults with self-reported hearing disability (n = 513) from the United States were included. The ICF components of body functions, activity and participation, and environmental factors were tested as the underlying structure of the HFEQ using confirmatory factor analysis and then adjusted by triangulation with previous content validation. RESULTS : The results of the current study confirmed the ICF components of body functions, activity and participation, and environmental factors as underlying constructs of the HFEQ. However, after triangulation with previous content validation, fine adjustments were made. The revised version of the HFEQ includes two removed items and a fine-tuned factor structure. CONCLUSION : The results confirm that the structure of the HFEQ aligns with the ICF, and the overall results indicate that HFEQ has acceptable construct validity and internal consistency.
Predictors of hearing loss disability : a multinational study using the ICF core set
(Taylor and Francis, 2025) Mahomed-Asmail, Faheema; Graham, Marien Alet; Swanepoel, De Wet; Manchaiah, Vinaya; Yerraguntlag, Krishna; Karlsson, Elin
PURPOSE : Objective audiological assessments provide valuable insights on physiological dimensions of hearing loss (HL), but not on lived experiences and functional limitations perceived by individuals. This study employed the multidimensional ICF framework to explore how demographic and diagnostic variables predict self-reported disability in adults with HL. METHOD : This cross-sectional study included 571 participants from India (94), South Africa (79), Sweden (219), and the USA (179). Responses from structured interviews based on the ICF were measured against demographic and diagnostic variables. RESULTS : 74.6% of the participants were hearing aid (HA) users with moderate-to-severe HL. Five statistically significant predictors were identified; HA usage, degree of HL, level of education, age, and income bracket. The predictors were associated with the ICF components; body functions (b126, b210, b230, b240), activity and participation (d310, d350) and environmental factors (e125, e250, e310, e355, e410, e460). CONCLUSIONS : This study emphasises that an individual’s experience with HL is significantly influenced by various factors beyond the severity of the HL itself. This underscores the ICF’s utility in capturing the complex interplay of biopsychosocial factors on HL. Identifying significant predictors could aid in tailoring interventions to improve health outcomes and quality of life for individuals with HL.

Cochlear nerve visualization in normal anatomy and inner ear malformations
(Wiley, 2024-12) Assiri, Majed; Khurayzi, Tawfiq; Almuhawas, Fida; Schlemmer, Kurt; Hagr, Abdulrahman; Dhanasingh, Anandhan
OBJECTIVES : This study aimed to qualitatively evaluate the variations in nerve bundles between patients with normal anatomy and those with inner-ear anomalies. METHODS : Magnetic resonance imaging (MRI) scans of the temporal bones of candidates for cochlear implants (CIs) enrolled at a tertiary center were retrospectively reviewed from the clinical database. The 3.0-Tesla MRI scans were analyzed using a three-dimensional slicer to visualize the nerve bundles in the internal auditory canal. RESULTS : A total of 49 ears were analyzed. Twenty ears exhibited normal inner ear anatomy, whereas 29 ears had various inner-ear malformations. The cochlear nerve (CN) was visible on all 20 scans with normal inner-ear anatomy. In addition, the CN was visualized in 18 scans with inner ear malformations. Furthermore, the CN was identified in six of the eight scans with IP type I, whereas in two scans, the CN and vestibular nerve were unclear. Three scans with a common cavity showed only two nerve bundles. CONCLUSION : The findings of this study show that the CN can be visualized in most inner-ear anatomical types. Even in severely malformed inner ears, the common nerve bundle that represents the cochlear and vestibular nerves can be visualized. The MRI is highly recommended for CN assessment before CI surgery. LEVEL OF EVIDENCE : Level IV.

Exploring autonomic dysfunction in functional dysphonia : a protocol for a case-control study and a randomized controlled trial
(Wiley, 2024-11) Meerschman, Iris; D'haeseleer, Evelien; Vanderhasselt, Marie-Anne; Claeys, Sofie; Vonck, Kristl; Vergauwe, Riet; Van Nuffelen, Gwen; Desuter, Gauthier; Roy, Nelson; Van Lierde, K.M. (Kristiane)
BACKGROUND : Although psychological factors have been implicated in patients with functional dysphonia (FD), conventional voice therapy (CVT) typically targets the aberrant voice symptoms exclusively. Yet, CVT is not always successful, and in view of the significant adverse quality of life impact combined with the financial burden on the healthcare system and society, research is needed to elucidate the underlying psychophysiology of FD and improve treatment outcomes. OBJECTIVES : The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic nervous system (ANS) dysfunction in patients with FD with gender- and age-matched vocally healthy controls, using a case-control study. The second objective is to compare the effects of a novel therapy for FD based on ANS regulation (i.e., ANS therapy: heart rate variability (HRV) biofeedback) on both autonomic function and voice function versus CVT alone or in combination with ANS therapy (i.e., ANS therapy + CVT), using a randomized controlled trial (RCT). METHODS : Case-control study: Autonomic (dys)function of patients with FD will be compared with gender- and age-matched vocally healthy controls, using both physiological measures (e.g., HRV, skin conductance level) and psychological patient-reported outcome measures (PROMs, e.g., Neuroception of Psychological Safety Scale, Depression Anxiety and Stress Scale). RCT: The FD group will be randomly assigned to the innovative ANS therapy group, the CVT group or the ANS therapy + CVT group. All patients received 1 month of treatment with 20 min of daily practice. Both the autonomic assessment and the voice assessment will be performed pretherapy and immediately after therapy by assessors blinded to group allocation and study phase. EXPECTED RESULTS : Higher occurrences of symptoms and/or disorders related to autonomic dysfunction are expected in patients with FD compared with vocally healthy controls. Physiological outcomes: lower HRV, lower cardiac pre-ejection period, higher respiration rate and higher skin conductance level are hypothesized in patients with FD compared with vocally healthy controls. Psychological PROMs: higher self-report of feelings/symptoms related to autonomic dysfunction (e.g., perceived stress, anxiety) is expected in patients with FD compared with vocally healthy controls. The autonomic function is hypothesized to improve more after the ANS therapy and the ANS therapy + CVT compared with the CVT only. Voice function is expected to improve more after the ANS therapy + CVT compared with the ANS therapy and the CVT alone. WHAT THIS PAPER ADDS : WHAT IS ALREADY KNOWN ON THE SUBJECT : Autonomic dysfunction is well recognized in the field of psychology but remains understudied in the area of voice. Given that the vagus nerve, innervating the larynx, also helps to regulate the ANS, and psychological symptoms commonly observed in patients with FD may reflect ANS dysregulation, research in this area is needed. There is some preliminary evidence that autonomic dysfunction might indeed be associated with FD. However, physiological ANS measures are needed, as well as validated psychological PROMs. WHAT THIS PAPER ADDS TO THE EXISTING KNOWLEDGE : The first objective of this study is to investigate the occurrence and frequency of symptoms and/or disorders related to autonomic dysfunction in patients with FD as compared with a gender- and age-matched vocally healthy control group. Autonomic (dys)function will be determined by employing both physiological measures (e.g., HRV, skin conductance level) and psychological PROMs (e.g., Neuroception of Psychological Safety Scale, Depression Anxiety and Stress Scale). The second objective is to compare the effects of a novel therapy for FD based on ANS regulation (HRV biofeedback) versus CVT alone or in combination with ANS therapy. WHAT ARE THE POTENTIAL OR ACTUAL CLINICAL IMPLICATIONS OF THIS WORK? Success rates of symptomatic CVT for FD are highly variable. This study is expected to lead to innovative results related to the pathogenesis and psychophysiology of FD, a prevalent voice disorder associated with a significant adverse quality of life impact and a substantial financial burden on the healthcare system and society. The results of this study will lead to crucial new insights into both the diagnosis and treatment of FD, contributing to evidence-based practice in the field of voice.

Nurses’ practices in stroke-related dysphagia in low- and middle-income countries
(AOSIS, 2024-03-28) Rowe, Kristen; Du Toit, Maria Neethling; Pillay, Sarveshvari B.; Kruger, Esedra; esedra.kruger@up.ac.za
BACKGROUND: Nurses are often required to perform dysphagia screening prior to oral intake by people following stroke. Previous studies report limited knowledge of nurses in identifying symptoms of post-stroke dysphagia. OBJECTIVE: To explore existing literature regarding nurses’ practices and knowledge in the identification and management of post-stroke oropharyngeal dysphagia (OPD) in low- and middle income countries (LMICs). METHOD: A scoping review was conducted according to the PRISMA-ScR guidelines. Studies were retrieved from PubMed, Scopus, EBSCOhost (CINAHL and Health source: Nursing and Academic edition), Web of Science Core collection, and Cochrane libraries. No time frame was applied, and all included studies were screened according to predefined eligibility criteria. RESULTS: Eight studies were included from 1 792 initial hits. Studies described nursing practices in acute care pertaining to identification and management of stroke-related dysphagia in LMICs. Increased knowledge was reported in nurses who had greater clinical experience in managing patients with dysphagia. Needs for training relating to dysphagia management and opportunities for interprofessional collaboration with speech-language therapists (SLTs) were identified. Contextual barriers specific to LMICs impacting on optimal nursing management of dysphagia included heavy workloads, staff-shortages and time constraints. CONCLUSION AND CONTRIBUTION: Eight studies described nurses’ practices and identified needs for the improvement of nurses’ dysphagia care in LMICs. This scoping review highlighted the urgency for further research in dysphagia management that provides creative, contextually relevant solutions for improved protocols and training of health care professionals. Findings may be valuable for the multidisciplinary team involved in post-stroke dysphagia care.
Tube feeding in advanced dementia : insights from South African speech-language therapists
(AOSIS Open Journals, 2024-02-12) Pullen, Danette; Pillay, Bhavani S.; Kruger, Esedra; bhavani.pillay@up.ac.za
BACKGROUND : Speech-language therapists (SLTs) may recommend tube feeding even with minimal research evidence of its effectiveness, and an understanding of SLTs’ perceived practices is warranted. OBJECTIVES : To qualitatively describe a sample of South African SLTs’ perceived practices regarding feeding tube placement in people with advanced dementia. METHOD : Semi-structured online interviews were conducted via Microsoft Teams. Eight South African SLTs with a particular interest in advanced dementia, in public and private settings, were recruited. Data were analysed using inductive reflexive thematic analysis. RESULTS : Three main themes were identified: (1) factors influencing SLTs’ decisions for feeding tube placement in people with advanced dementia; (2) nature of clinical setting and SLTs’ decision-making and (3) SLTs’ considerations to improve management of people with advanced dementia. Existing local palliative care guidelines were not employed in decisions about tube feeding. Most participants did not recommend tube feeding during end-of-life care. Perceived burden of care influenced participants’ decisions about tube feeding. CONCLUSION : Speech-language therapists in South Africa likely have an increased reliance on clinical experience rather than recent research and guidelines for decisions about feeding tube placement. Findings accentuate the importance of clinical supervision, mentoring and continuous professional development in the workplace. The findings are an urgent call to action to improve SLTs’ overall practices and ethical service delivery for people with advanced dementia and their families. CONTRIBUTION : Factors and needs regarding SLTs’ decision-making about feeding tubes in people with advanced dementia are highlighted.
Swallowing and feeding of young children on high-flow oxygen therapy
(AOSIS, 2024-03-02) Hoosain, Ruhee; Pillay, Bhavani S.; Abdoola, Shabnam Salim; Graham, Marien Alet; Kruger, Esedra
BACKGROUND : Oral feeding practices of young patients on high-flow oxygen (HFO2) have been controversial. Limited literature exists on this topic, but new studies suggest introducing oral feeds. OBJECTIVE : This study aims to describe the changes in swallowing and feeding of a group of young children on HFO2. METHOD : Twelve participants (mean age 34.17 months [s.d. = 3.97]) on HFO2 were assessed clinically at the bedside using the Schedule of Oral Motor Assessment. Assessments were conducted twice to determine the change in characteristics: upon approval from the managing doctor when respiratory stability on HFO2 was achieved and for a second time on the last day of receiving HFO2 (mean 2.6 days apart). Patients received standard in-patient care and speech therapy intervention. RESULTS : Most participants displayed typical oral motor function at initial and final assessments for liquid, puree and semi-solid consistencies. Purees and soft solid consistencies were introduced to most participants (n = 11, 91.7%). Solids and chewables were challenging for all participants during both assessments. Half of the participants displayed gagging and a wet vocal quality with thin liquids at the initial assessment only. CONCLUSION : This small-scale study found that HFO2 should not preclude oral diets, but in this sample, small amounts of oral feeding could be introduced with caution, in an individualised manner, and with a collaborative multidisciplinary approach. Further research is essential. CONTRIBUTION : Partial oral feeding of specific consistencies was possible during the assessment of young paediatric in-patients on HFO2. Monitoring of individual patient characteristics and risk factors by a specialist feeding team is essential.
Caregivers’ perspectives of early developmental tele-assessments in challenging circumstances
(AOSIS, 2024-07-23) Du Toit, Maria Neethling; Eccles, Renata; Westwood, Kailin Amber; Graham, Marien Alet; Van der Linde, Jeannie
BACKGROUND : Outbreaks, such as the COVID-19 pandemic in 2020, exacerbate barriers to accessing early childhood developmental care. Tele-assessment may serve as an innovative approach to developmental monitoring to overcome service delivery amidst challenging circumstances. It is vital to collect caregivers’ perspectives of this potential service delivery method to inform clinical decision making. OBJECTIVES : This study aimed to determine caregivers’ perspectives of interview-based early developmental tele-assessment in a South African context. METHOD : Thirty caregivers of children (aged birth – 36 months) completed a caregiver-report developmental assessment via a telecommunications platform, as well as an online questionnaire probing their perspectives on the tele-assessment. RESULTS : Most participants (96.7%, n = 29 out of 30) rated their overall experience of the teleassessment as positive; however, 53.8% (n = 14 out of 26 that answered the question) indicated that they would additionally still prefer in-person assessment. CONCLUSION : Tele-assessment appears to be a viable approach for caregivers to access developmental care during circumstances such as COVID-19. CONTRIBUTION : This study provided valuable insight into a novel approach using interviewbased early developmental tele-assessment and the perspectives of caregivers thereof.
A swallowing and breastfeeding intervention programme for small and sick neonates embedded in kangaroo mother care
(AOSIS, 2024-08-09) Kritzinger, Alta M. (Aletta Margaretha); Van Rooyen, Elise; Bergh, Anne-Marie; alta.kritzinger@up.ac.za
Available evidence of oral sensorimotor interventions for small neonates is not strong. Evidence of interventions for sick term neonates is largely lacking. Studies are limited by risk of bias and inconsistency. Evidence of interventions relying on a single stimulation technique only appears to be low to very low. Ongoing research is required. CONTRIBUTION : We describe a five-component neonatal swallowing and breastfeeding intervention programme embedded in the practice of kangaroo mother care (KMC). Drawing on oropharyngeal physiology, neonatology, neurodevelopmental care, breastfeeding- and KMC science, the programme is the product of collaboration between a speech-language therapist and a medical doctor, and their team. Its implementation is dependent on coaching mothers and the neonatal care team. Researchers are invited to determine outcomes of the programme.
Perspectives on hearing aid cost and uptake for prescription and over-the-counter hearing aid users
(American Speech-Language-Hearing Association, 2024-09) Knoetze, Megan Clarissa; Manchaiah, Vinaya; Oosthuizen, Ilze; Beukes, Eldre W.; Swanepoel, De Wet; dewet.swanepoel@up.ac.za
PURPOSE : This study explored user perspectives on the relationship between hearing aid cost and uptake, as well as cost-related recommendations for others with hearing difficulties, in a sample of prescription and over-the-counter (OTC) hearing aid users. METHOD : A secondary analysis was conducted on a cross-sectional survey using qualitative content analysis to analyze responses related to the cost of hearing aids. The study included a total of 241 adult participants, comprising 179 prescription hearing aid users from the Hearing Tracker website and 62 OTC hearing aid users from the Lexie Hearing U.S. database. RESULTS : Prescription users had a mean age of 66.7 years (SD = 13.2), including 62.0% males, 37.4% females, and 0.6% nonbinary individuals. OTC users had a mean age of 63.0 years (SD = 13.4), with 48.4% males and 51.6% females. Three overarching domains were identified: perceived enablers to hearing aid uptake related to the cost, perceived barriers to hearing aid uptake related to the cost, and recommendations to others with hearing difficulties related to the cost, with 14 categories recognized for prescription users and 12 for OTC users. Both groups identified the high cost of hearing aids and lack of insurance coverage as significant barriers to uptake. Many prescription users reported external support (e.g., financial support and health insurance coverage) as an enabler, while OTC users frequently mentioned the affordability of OTC devices. The most common recommendation among prescription users was to seek professional support, whereas OTC users recommended researching hearing aids before making a purchase. CONCLUSIONS : Cost and insurance coverage consistently emerge as primary barriers to hearing aid adoption for both prescription and OTC users. To foster greater accessibility, initiatives should target these financial obstacles. Additional research is warranted on the relationship between hearing aid cost and uptake, especially among OTC users and those seeking financial assistance.

The indirect effect of an internet-based intervention on third-party disability for significant others of individuals with tinnitus
(MDPI, 2024-10) Beukes, Eldre W.; Andersson, Gerhard; Manchaiah, Vinaya
BACKGROUND : This study aimed to investigate whether Internet-based cognitive behavioural therapy intervention (ICBT) for individuals with tinnitus had an indirect effect on the third-party disability noticed by significant others (SOs). METHODS : Significant Others Questionnaire (CTSOQ). Individuals with tinnitus completed standardized self-reported outcome measures for tinnitus severity, anxiety, depression, insomnia, hearing-related quality of life, tinnitus cognitions, hearing disability, and hyperacusis. RESULTS : In total, 194 pairs of individuals with tinnitus and their SOs participated. The impact of third-party disability experienced by SOs was significantly reduced after individuals with tinnitus undertook the ICBT intervention (d = 0.41). This reduced SOs with severe difficulties from 52% to 35%. The remaining impact was mild for 30% and moderate for 35%. SOs with higher baseline difficulties and SOs who were partners (e.g., spouses) were less likely to notice indirect benefits from intervention undertaken by their family members. There was a moderate positive correlation between the post-intervention CTSOQs and the clinical variables of tinnitus severity and depression. CONCLUSIONS : Third-party disability may be reduced as an indirect effect of individuals with tinnitus undertaking ICBT. Including SOs of individuals with tinnitus within the rehabilitation process may add additional benefits, and such involvement should be encouraged.
