Development and validation of a questionnaire for assessing visual and auditory spatial localization abilities in dual sensory impairment.

Spatial localization is important for social interaction and safe mobility, and relies heavily on vision and hearing. While people with vision or hearing impairment compensate with their intact sense, people with dual sensory impairment (DSI) may require rehabilitation strategies that take both impairments into account. There is currently no tool for assessing the joint effect of vision and hearing impairment on spatial localization in this large and increasing population. To this end, we developed a novel Dual Sensory Spatial Localization Questionnaire (DS-SLQ) that consists of 35 everyday spatial localization tasks. The DS-SLQ asks participants about their difficulty completing different tasks using only vision or hearing, as well as the primary sense they rely on for each task. We administered the DS-SLQ to 104 participants with heterogenous vision and hearing status. Rasch analysis confirmed the psychometric validity of the DS-SLQ and the feasibility of comparing vision and hearing spatial abilities in a unified framework. Vision and hearing impairment were associated with decreased visual and auditory spatial abilities. Differences between vision and hearing abilities predicted overall sensory reliance patterns. In DSI rehabilitation, DS-SLQ may be useful for measuring vision and hearing spatial localization abilities and predicting the better sense for completing different spatial localization tasks.

Development of core sets for deafblindness: an international expert survey on functioning and disability of individuals living with deafblindness using the International Classification of Functioning, Disability, and Health.

BACKGROUND: The development of International Classification of Functioning, Disability, and Health (ICF) Core Sets greatly enhances the global recognition of health conditions, thereby advancing research, education, and care provision. Aside from the work of researchers, and the viewpoint of persons with lived experience, the development of Core Sets for deafblindness needs to include the viewpoints of professionals with expertise unique to this condition. AIM: To represent the perspective of health and social service expert professionals in the development of ICF Core Sets for deafblindness. DESIGN: Cross-sectional cohort study. SETTING: Global online survey representing all six regions of the World Health Organization. POPULATION: One hundred and five professionals providing and health or social service to individuals living with deafblindness with a minimum of 2 years of work experience with this population. METHODS: An online survey was distributed through professional networks and social media for individuals working with persons living with deafblindness. Demographic items were summarized using descriptive statistics. Six open-ended questions explored the perceptions of body functions and structures that influence activities and participation, as well as environmental and personal factors that facilitate functioning. Data were linked to the ICF codes using established linking rules and procedures. RESULTS: The 2934 survey response units were linked using IFC categories. Of the 421 unique categories, 133 were used by 5% or more of respondents. Most categories within the Activities and Participation component were equally emphasized. The most frequent Environmental factors were support and relationships, services, systems, and policies, as well as and the physical environment (e.g., hearing aids or noise). Mental functions, including higher level cognitive functions, temperament and personality were frequently emphasized. CONCLUSIONS: Almost three quarters (73.3%) of the entire ICF classification categories were included in the expert survey results. This proportion emphasizes the importance of a multidimensional tool, such as the ICF, for assessing functioning and health for persons with deafblindness. CLINICAL REHABILITATION IMPACT: The representation of this professional perspective in Core Set development will improve standardized assessment and documentation, intervention planning, and facilitate interprofessional communication with the goal of improving person-centered care for persons living with deafblindness.

APOE-ε4 is not associated with pure-tone hearing thresholds, visual acuity or cognition, cross-sectionally or over 3 years of follow up in the Canadian Longitudinal Study on Aging.

INTRODUCTION: Hearing loss and diminished visual acuity are associated with poorer cognition, but the underlying mechanisms are not understood. The apolipoprotein (APOE) ε4 allelic variant may drive the associations. We tested whether APOE-ε4 allele count (0, 1, or 2) was associated with declines in memory, executive function, pure-tone hearing threshold averages, and pinhole-corrected visual acuity among participants in the Canadian Longitudinal Study on Aging (CLSA). METHODS: Multivariable linear mixed regression models were utilized to assess associations between APOE-ε4 allele count and each of the outcome variables. For each main effects model, interactions between APOE-ε4 and sex and age group (45-54-, 55-64-, 65-74-, and 75-85 years) respectively, were analyzed. RESULTS: Significant associations were not observed in main effects models. Models including APOE-ε4 * age (but not APOE-ε4 * sex) interaction terms better fit the data compared to main effects models. In age group-stratified models, however, there were minimal differences in effect estimates according to allele count. CONCLUSION: APOE-ε4 allele count does not appear to be a common cause of sensory-cognitive associations in this large cohort.

Strategies used during the cognitive evaluation of older adults with dual sensory impairment: a scoping review.

BACKGROUND: Dual sensory impairment (DSI), the combination of visual and hearing impairments, is associated with increased risk for age-related cognitive decline and dementia. Administering cognitive tests to individuals with sensory impairment is challenging because most cognitive measures require sufficient hearing and vision. Considering sensory limitations during cognitive test administration is necessary so that the effects of sensory and cognitive abilities on test performance can be differentiated and the validity of test results optimized. OBJECTIVE: To review empirical strategies that researchers have employed to accommodate DSI during cognitive testing of older adults. METHODS: Seven databases (MEDLINE, Embase, Web of Science, CINAHL, PsycINFO, Global Health and the Evidence-Based Medicine Reviews databases) were searched for relevant articles integrating the three concepts of cognitive evaluation, aging, and DSI. Given the inclusion criteria, this scoping review included a total of 67 papers. RESULTS: Twenty-eight studies reported five categories of strategies for cognitive testing of older adult participants with DSI: the assistance of experts, the modification of standardized test scoring procedures, the use of communication strategies, environmental modifications, and the use of cognitive tests without visual and/or auditory items. CONCLUSIONS: The most used strategy reported in the included studies was drawing on the assistance of team members from related fields during the administration and interpretation of cognitive screening measures. Alternative strategies were rarely employed. Future research is needed to explore the knowledge-to-practice gap between research and current clinical practice, and to develop standardized testing strategies.

Digital tools to support technology-enabled budget management in people with acquired brain injury: a rapid review.

People with acquired brain injuries (ABI) face financial challenges that affect their daily lives. Managing finances is a crucial activity that can help avoid social isolation. However, this task becomes difficult for people with ABI because of their cognitive impairments. Recent advances in digital technology can help people with ABI manage their finances more effectively. This study aims to identify and describe available digital tools that can help ABI in budget management, and identify their effectiveness, barriers and facilitators to implementation. To address this issue, we conducted a rapid review of academic databases followed by a modified Google/Google Scholar search to identify the digital tools to support budgeting tasks (DBT) used and tested by people with ABI. Our rapid review included only two articles on the use of DBT. The first study showed that common portable electronic devices were acceptable and desirable as memory and organisational aids for people with ABI. The second study documented the development of a DBT and the perception of users (research participants) who found it appealing and user-friendly. However, for both articles, the technologies used are outdated and lack information on barriers and facilitators to using DBT. In conclusion, this literature review revealed that digital technologies have the potential to support budget management in people with ABI, but technology needs to be made available on the market to benefit the users. Further research and development are needed to create new ways to help people with brain injuries manage their budgets.

Our study showed limited literature involving appropriate digital tools to support budgeting task (DBT) to meet the needs of people with acquired brain injury (ABI) to manage their budgets. Therefore, further research is encouraged to develop digital tools adapted to the budgeting needs and cognitive impairments of people with ABI and their socio-cultural environment.Our paper provides recommendations to develop human-centred digital solutions to help people with ABI manage their budgets, that are accessible, reliable and sustainable. Mixed methods and mix of methods are highly recommended in this regard.

Double-Blind Comparison of Eyelash Epilation Techniques for the Purpose of Demodex folliculorum Mite Retrieval.

OBJECTIVE: Demodex folliculorum blepharitis is typically confirmed with lash epilation and microscopic identification of mites. However, mite counts may vary with the epilation technique. As there is no gold standard to epilating lashes for the purposes of mite counts, the aim of this study was to compare three epilation techniques. METHOD: A prospective randomized double-blind study compared three epilation techniques on lashes with cylindrical dandruff. Techniques included (A) direct pulling of the lash; (B) rotating the lash before epilation; and (C) sliding the cylindrical dandruff away, lash rotation, and epilation. Mean mite counts were analyzed using a repeated-measures analysis of variance. RESULTS: Forty (n=40) participants (20 M: 20 F, mean age of 62.3±17.1 years) revealed similar mite counts between right (1.43±1.74) and left (1.35±1.59) eyes ( P =0.63). A significant difference ( P =0.03) in mite count was noted (technique A: 1.05 ± 1.60; technique B 1.76 ± 1.80; and technique C 1.36 ± 1.54) with technique B yielding the highest mite count ( P =0.04). CONCLUSION: Demodex mite count is a key parameter in establishing infestation or to determine treatment efficacy. This study revealed that rotating the lash before epilation yielded the highest mite count. Future studies should report the epilation technique used to allow for study comparisons.

Does social connection mediate the association between neuroticism and cognition? Cross-sectional analysis of the Canadian Longitudinal Study on Aging.

OBJECTIVES: This study tested the association between neuroticism and six cognitive measures, and examined the potential mediating roles of social connection (social isolation and loneliness) among middle-aged and older adults. METHODS: This cross-sectional study was a secondary analysis of the Canadian Longitudinal Study on Aging (CLSA) Comprehensive Cohort, a sample of Canadians aged 45-85 years at baseline. Respondents with data collected at the first follow-up, between 2015 and 2018, were included (n = 27,765). Structural equation modelling was used to assess the association between neuroticism and six cognitive measures (Rey Auditory Verbal Learning Test immediate recall and delayed recall, Animal Fluency Test, Mental Alternation Test, Controlled Oral Word Association Test and Stroop Test interference ratio), with direct and indirect effects (through social isolation and loneliness). All analyses were stratified by sex, including females (n = 14,133) and males (n = 13,632). RESULTS: In unadjusted models, there was evidence of associations between neuroticism and all cognitive measures, except the Stroop Test interference ratio, suggesting higher neuroticism was associated with lower scores on memory and executive function tests. In the models of these other five outcomes, there was consistent evidence of indirect effects (through social isolation and loneliness) and, in some cases, direct effects. The results are discussed in context with limitations, including the use of cross-sectional design and alternative hypotheses to explain the association between personality and cognition. CONCLUSION: Among middle-aged and older adults, for both males and females, the findings suggest that the association between neuroticism and cognitive outcomes may be mediated by aspects of social connection.

Towards identifying gaps in employment integration of people living with vision impairment: A scoping review.

BACKGROUND: The high rate of unemployment among individuals with vision impairment remains a pressing issue, even with the implementation of disability laws and coordinated effort to foster inclusive workplace. Employment integration challenges persist for people with vision impairment due to inaccessible job markets and workplaces. OBJECTIVE: To create new knowledge from previous studies related to employment among people with vision impairment and to understand what has been explored and identify the gaps in employment integration. METHOD: A comprehensive search of six databases was conducted utilizing both index terms and keywords. The title and abstract of identified studies were screened, followed by a full-text screening using pre-set criteria. Only available peer-reviewed studies with a focus on employment and vision impairment were included, irrespective of location and publication year. RESULT: Of 2264 studies screened, only 43 studies were eligible for review and data extraction. Using thematic analysis, 8 key themes emerged: social support, disability rights and service systems, transition strategies and challenges, career, employment integration, employment environment, adaptive potential, and employment sustainability. These studies considered the perspectives of people living with vision impairment, rehabilitation practice, and employers. Identified gaps include transition strategies, workplace participation, the perception of colleagues, and work evolution. CONCLUSION: The primary focus of studies was on the individual factors that impact workplace integration; work environment impact was not explored in depth. The need to examine the readiness of the work environment is also importance because environmental factors can be modified according to the functional needs of people with vision impairment.

At-home computerized executive-function training to improve cognition and mobility in normal-hearing adults and older hearing aid users: a multi-centre, single-blinded randomized controlled trial.

BACKGROUND: Hearing loss predicts cognitive decline and falls risk. It has been argued that degraded hearing makes listening effortful, causing competition for higher-level cognitive resources needed for secondary cognitive or motor tasks. Therefore, executive function training has the potential to improve cognitive performance, in turn improving mobility, especially when older adults with hearing loss are engaged in effortful listening. Moreover, research using mobile neuroimaging and ecologically valid measures of cognition and mobility in this population is limited. The objective of this research is to examine the effect of at-home cognitive training on dual-task performance using laboratory and simulated real-world conditions in normal-hearing adults and older hearing aid users. We hypothesize that executive function training will lead to greater improvements in cognitive-motor dual-task performance compared to a wait-list control group. We also hypothesize that executive function training will lead to the largest dual-task improvements in older hearing aid users, followed by normal-hearing older adults, and then middle-aged adults. METHODS: A multi-site (Concordia University and KITE-Toronto Rehabilitation Institute, University Health Network) single-blinded randomized controlled trial will be conducted whereby participants are randomized to either 12 weeks of at-home computerized executive function training or a wait-list control. Participants will consist of normal-hearing middle-aged adults (45-60 years old) and older adults (65-80 years old), as well as older hearing aid users (65-80 years old, ≥ 6 months hearing aid experience). Separate samples will undergo the same training protocol and the same pre- and post-evaluations of cognition, hearing, and mobility across sites. The primary dual-task outcome measures will involve either static balance (KITE site) or treadmill walking (Concordia site) with a secondary auditory-cognitive task. Dual-task performance will be assessed in an immersive virtual reality environment in KITE's StreetLab and brain activity will be measured using functional near infrared spectroscopy at Concordia's PERFORM Centre. DISCUSSION: This research will establish the efficacy of an at-home cognitive training program on complex auditory and motor functioning under laboratory and simulated real-world conditions. This will contribute to rehabilitation strategies in order to mitigate or prevent physical and cognitive decline in older adults with hearing loss. TRIAL REGISTRATION: Identifier: NCT05418998. https://clinicaltrials.gov/ct2/show/NCT05418998.

Using co-creation focus groups to customise a remote multidomain programme designed to increase dementia literacy.

OBJECTIVES: To adapt the content and functionalities of Brain Health PRO, a web-based multidomain program designed to increase dementia literacy, to the context and needs of users, providers and community organisations across Québec, Canada. DESIGN: Five consecutive qualitative co-creation focus group sessions 30-90 min in duration each, exploring potential barriers and facilitators to usability, accessibility, comprehensibility, participant recruitment and retention. SETTING: Virtual meetings. PARTICIPANTS: A 15-member team based in Québec and Ontario, Canada, consisting of 9 researchers (including a graduate student and the project coordinator), representing occupational therapy, sensory rehabilitation, neuropsychology, psychology, health science and research methods, 3 informal caregivers of older adults living with cognitive decline and 3 members of the Federation of Quebec Alzheimer Societies. DATA ANALYSIS: Session recordings were summarised through both qualitative description and thematic analysis. RESULTS: The synthesised recommendations included adjustments around diversity, the complexity and presentation styles of the materials, suggestions on refining the web interface and the measurement approaches; it influenced aspects of participant recruitment, retention efforts and engagement with the content of Brain Health PRO. CONCLUSIONS: Co-creation in dementia prevention research is important because it involves collaboration between researchers, community support and service providers, and persons with lived experience as care providers, in the design and implementation of clinical studies. This approach helps to ensure that the content and presentation of educational material is relevant and meaningful to the target population and those involved in its delivery, and it leads to a greater understanding of their needs and perspectives.

Financial Inequities in Optometric Education in Canada: A Comparison of Two Optometry Programs.

SIGNIFICANCE: The advancing age of the population will require increased access to eye care services to manage eye diseases and vision correction. Optometric education requires a sound financial plan to manage student debt. This study evaluates the financial inequalities of optometric programs in Canada and how this may impact the provision of eye care professionals. PURPOSE: The objective of this study was to compare the financial inequities in optometric education in Canada from the 2020 graduating class. METHODS: A cross-sectional study assessed monetary variables related to the study of optometry in Canada, including academic and personal expenses, and overall debt and expenses related to the COVID-19 lockdown for the 2020 graduating class. RESULTS: A total of 108 optometry students from the 2020 graduating classes of the University of Montreal and the University of Waterloo responded, with 68 (female/male respondents, 53:15; mean [standard deviation] age, 25.66 [2.01] years) completing the study. Waterloo students spent more years in university ( P < .001), had higher academic fees ( P < .001), spent more on traveling to their family residence ( P = .007), and received more provincial ( P = .002) and federal ( P < .001) loans than Montreal students. Overall debt before optometry was similar among students but differed ( P < .001) at the end of their program, with Waterloo students having a higher debt burden. CONCLUSIONS: There is a financial inequity in optometric education in Canada depending on the chosen program. Cumulative optometry student debt for the 2020 graduating class in Canada ranges from Can $0 to $189,000 with an average of Can $65,800 and a median of Can $50,000. The results of this study can assist financial and government agencies, and future optometry students to better understand the financial burdens and establish a financial plan to study optometry in Canada, to respond to the growing eye care needs of the public.

The International Classification of Functioning, Disability and Health Core Set for deafblindness. Part I: a systematic review of outcome measures.

INTRODUCTION: The International Classification of Functioning, Disability, and Health (ICF), developed by the World Health Organization, is a classification framework that focuses on the health and functioning of people with disabilities. As part of an ICF Core Set development, four studies need to be conducted, one of which is a systematic review. This study presents part 1 of the systematic review that aims to describe the outcome measures identified in the literature related to functioning in individuals with deafblindness. EVIDENCE ACQUISITION: The research team screened articles from eight scientific databases, three journals, and Google Scholar (March 2011 to September 2022). Articles were included if they studied individuals with deafblindness aged 18 and older. Studies that examined genetics or laboratory experiments involving animals were excluded. Data were extracted into a logbook with key descriptors such as study location and design, age of study population, and instruments/outcome measures used, which were further categorized into one of the following types: 1) standardized; 2) patient-reported measures, standardized (PT-S); 3) patient-reported measures, not standardized (PT-not S); 4) health professional, reported measures, standardized (HP-S); 5) Technical measures; 6) other measures (parent-reported standardized and laboratory measures). EVIDENCE SYNTHESIS: The review included 147 studies, of which most were conducted in Europe (47.6%) and North America (27.9%). Of the 314 identified outcome measures, 57 were Standardized, 59 were Patient Reported-Standardized (PT-S), 178 were patient reported non-standardized (PT-Not S) variables, 11 were health professional reported, standardized, five were technical, and four were classified as other measures. CONCLUSIONS: Most instruments measured functioning in daily activities and the mental health of individuals with deafblindness. Three deafblind-specific instruments were identified in this study, highlighting the need for more deafblind-specific instruments to be developed and utilized in research.

Associations Between Cardiovascular Risk Factors and Audiometric Hearing: Findings From the Canadian Longitudinal Study on Aging.

OBJECTIVES: The objectives of the study were to determine, among a population-based sample of Canadian adults, if risk factors for cardiovascular disease (alone and in combination) were associated with hearing loss. Cross-sectional and longitudinal associations (the latter with about 3 years of follow-up) were examined. Risk factors considered included diabetes, dyslipidemia, hypertension, obesity, and smoking. We also aimed to determine if associations were modified by sex and age group (45 to 54, 55 to 64, 65 to 74, and 75 to 86 years old at baseline). DESIGN: A secondary analysis of data collected for the Canadian Longitudinal Study on Aging was performed. Data were collected in two waves, the first between 2012 and 2015, and the second between 2015 and 2018. Hearing was measured using screening air-conduction pure-tone audiometry. The outcome of interest was defined as the mid-frequency (1000, 2000, 3000, and 4000 Hz) pure-tone average for both ears. Diabetes was defined based on self-reported physician diagnosis, use of diabetes medications, or a hemoglobin A1c level ≥6.5%. Dyslipidemia was determined by blood lipid profile as defined using the Canadian guidelines for the diagnosis and treatment of dyslipidemia (low-density lipoprotein cholesterol ≥3.5 mmol/L or non-high-density lipoprotein cholesterol ≥4.3 mmol/L). Hypertension was determined by self-reported physician diagnosis or an average systolic blood pressure ≥140 mm Hg or an average diastolic blood pressure ≥90 mm Hg. Obesity was defined as a waist-to-height ratio ≥0.6. Smoking history was determined by self-report (current/former/never-smoker). Two composite measures of cardiovascular risk were also constructed: a count of the number of risk factors and a general cardiovascular risk profile (Framingham) score. Independent associations between risk factors for cardiovascular disease and hearing were determined using multivariable regression models. Survey weights were incorporated into the analyses. All results were disaggregated by sex. Effect modification according to age was determined using multiplicative interaction terms between the age group and each of the risk factor variables. A complete case (listwise deletion) approach was performed for the primary analysis. We then repeated the multivariable regression analyses using multiple imputation using chained equations to determine if the different approaches to dealing with missing data qualitatively changed the outcomes. RESULTS: In longitudinal analyses, hypertension and the general cardiovascular risk profile score were associated with greater loss of hearing over the 3-year follow-up period for both sexes. In addition, smoking in males and obesity in females were associated with faster rates of hearing decline. In cross-sectional analyses, smoking, obesity, diabetes, and composite measures were each independently associated with worse hearing for both sexes (although for females, obesity was only associated with hearing loss in the 55 to 64-year-old age group). The results were similar for the complete case and multiple imputation approaches, but more cross-sectional associations were observed using multiple imputation. CONCLUSIONS: Diabetes, obesity, hypertension, and smoking were associated with hearing loss. Higher combinations of risk factors increased the risk of hearing loss. Further studies are needed to confirm age and sex differences and whether interventions to address these risk factors could slow the progression of hearing loss in older adults.

Evaluating the implementation of the Mayo-Portland Adaptability Inventory-4 (MPAI-4) in three rehabilitation settings in Quebec: a mixed-methods study protocol.

INTRODUCTION: Stroke is a leading cause of morbidity and mortality worldwide, placing an immense burden on patients and the health system. Timely access to rehabilitation services can improve stroke survivors' quality of life. The use of standardised outcome measures is endorsed for optimising patient rehabilitation outcomes and improving clinical decision-making. This project results from a provincially mandated recommendation to use the fourth version of the Mayo-Portland Adaptability Inventory (MPAI-4) to measure changes in social participation of stroke survivors and to maintain commitment to evidence-informed practices in stroke care. This protocol outlines the implementation process of the MPAI-4 for three rehabilitation centres. The objectives are to: (a) describe the context of MPAI-4 implementation; (b) determine clinical teams' readiness for change; (c) identify barriers and enablers to implementing the MPAI-4 and match the implementation strategies; (d) evaluate the MPAI-4 implementation outcomes including the degree of integration of the MPAI-4 into clinical practice and (e) explore participants' experiences using the MPAI-4. METHODS AND ANALYSIS: We will use a multiple case study design within an integrated knowledge translation (iKT) approach with active engagement from key informants. Each case is a rehabilitation centre implementing MPAI-4. We will collect data from clinicians and programme managers using mixed methods guided by several theoretical frameworks. Data sources include surveys, focus groups and patient charts. We will conduct descriptive, correlational and content analyses. Ultimately, we will analyse, integrate data from qualitative and quantitative components and report them within and across participating sites. Results will provide insights about iKT within stroke rehabilitation settings that could be applied to future research projects. ETHICS AND DISSEMINATION: The project received Institutional Review Board approval from the Centre for Interdisciplinary Research in Rehabilitation of Greater Montreal. We will disseminate results in peer-reviewed publications and at local, national and international scientific conferences.

Visual and cognitive functioning among older adults with low vision before vision rehabilitation: A pilot study.

Introduction: The occurrence of age-related vision changes is inevitable. However, some of these changes can become pathological. Research indicates that vision and hearing loss is correlated with age-related cognitive decline, and with a higher risk of developing dementia due to Alzheimer's disease. Low vision rehabilitation could possibly be a protective factor against cognitive decline, as it provides the clients with compensatory strategies to overcome their visual deficits. Objectives and hypothesis: The aim of this pilot study was to assess correlations between visual and cognitive functions in older adults referred for low vision rehabilitation. We hypothesized that more severe impairment of visual acuity and contrast sensitivity would be correlated with more advanced levels of cognitive impairment. The second objective was to examine which of these correlations would remain significant once established variables that influence cognition are statistically removed (e.g., age, education). Methods: Thirty-eight older adults (age range: 66-97 years old) with a visual impairment (acuity <20/70) were recruited before the onset of their low vision rehabilitation. They underwent vision (reading acuity, reading speed, contrast sensitivity), hearing (audiogram, speech-in-noise perception) and cognitive (global cognition, memory, executive functions) testing, and demographic information was obtained. Results and discussion: Correlations among global cognition and visual aid use, memory and reading speed, memory and contrast sensitivity, memory, and visual aid use, and between executive functions and contrast sensitivity were significant. Correlations between contrast sensitivity and memory, as well as between global cognition and visual aid use remained significant after controlling for age and education. The present study is relevant to clinicians who are assessing the cognitive status of older adults, such as neuropsychologists, because it highlights the importance of considering low vision when administering neuropsychological tests, especially to persons who have not yet received rehabilitation for their visual impairment.

Continuum of Care for Older Adults With Concurrent Hearing and Vision Impairment: A Systematic Review.

Background and Objectives: A global report estimates up to 2% of the world population experience concurrent hearing and vision impairment (dual sensory impairment [DSI]). Older adults with DSI are often frequent users of health care, yet the evidence is limited to inform care delivery for this population. This systematic review aimed to synthesize evidence on tools and strategies for screening, assessment, and interventions that promote a continuum of care for older adults with DSI. Research Design and Methods: The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews. Electronic databases (CINAHL, Embase, MEDLINE, PsycINFO, Cochrane Library, Global Health, and Web of Science) and clinical trial registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials.gov) were searched. The quality appraisal was performed using the Mixed Methods Appraisal Tool. Results: Of 4,775 identified references, 28 records were selected. The review identified 7 tools and 7 strategies for DSI-specific screening, assessments, and/or interventions. Some of the most promising tools were the interRAI Community Health Assessment with deafblind supplement, adapted Montreal Cognitive Assessment, and the Severe Dual Sensory Loss screening tool. Useful strategies included the use of alternative forms of communication, assistive devices or technology, education and training for service providers, and training of older adults on the use and maintenance of assistive aids/technology. However, quality appraisal indicated a need for more robust evidence to inform clinical practice. Discussion and Implications: Reviewed evidence pinpointed the need for training for health care providers on DSI-specific challenges and supports and the use of integrated multidisciplinary care for older adults. Future studies need to explore the development and evaluation of tools and interventions to improve the continuum of care for this group. Systematic Review Registration: PROSPERO registration # CRD42020180545.

Are cognitive researchers ignoring their senses? The problem of sensory deficit in cognitive aging research.

Sensory impairments are common in older adult populations and have notable impacts on aging outcomes. Relationships between sensory and cognitive functions have been clearly established, though the mechanisms underlying those relationships are not fully understood. Given the growing burden of dementia, older adults with sensory deficits are an important and growing population to study in cognitive aging research. Yet, cognitive research sometimes excludes those with uncorrected significant/severe sensory deficits and often poorly or inconsistently assesses those deficits. Observational and interventional studies that exclude participants with sensory deficits will be limited in their generalizability to the narrower subset of the older adult population without vision or hearing impairment and may be missing an opportunity to study a growing population of older adults at higher risk of cognitive impairment. Strategies exist for adapting cognitive testing instruments, and inroads could be made into collecting normative data to inform ongoing research. Bringing together psychometricians with researchers who specialize in vision and hearing impairments could launch highly innovative research on both measurement methods and cognitive disease etiology, as sensory organs provide readily accessible neuronal and vascular beds that may show pathology earlier and elucidate innovative screening opportunities for early signs of cognitive disease.

Sex-Specific Interactions Between Hearing and Memory in Older Adults With Mild Cognitive Impairment: Findings From the COMPASS-ND Study.

OBJECTIVES: Hearing loss (HL) in older adults is associated with a decline in performance on cognitive tasks and the risk of developing dementia. However, very few studies have investigated sex-related effects on these associations. A previous study of cognitively healthy older adults showed an association between HL and lower cognitive performance in females only. In the present study, we examined the effects of sex and hearing on cognition in individuals with mild cognitive impairment (MCI). We predicted that females with HL would be more likely to show poorer performance on the cognitive measures compared to females with normal hearing (NH), while cognitive performance in males would not depend on hearing. We further predicted that these auditory-cognitive associations would not depend on test modality, and would thus be observed in females for both auditory and visual tests. DESIGN: Participants were 101 older adults with amnestic MCI (M = 71 years, 45% females) in the Canadian Consortium on Neurodegeneration in Aging (CCNA) COMPASS-ND study. Performance on the Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning (RAVLT), and Brief Visuospatial Memory Test-Revised (BVMT-R) was analyzed to investigate sex-related differences and/or hearing-related differences. Participants were categorized as having NH or HL using two different measures: pure-tone hearing screening results (normal based on a pure-tone threshold < 25 dB HL at 2000 Hz in the worse ear) and speech-in-noise speech reception thresholds (SRTs; normal < -10 dB SNR on the Canadian Digit Triplet Test [CDTT]). RESULTS: Males and female groups did not differ in age, years of education, or other relevant covariates. Yet, females with better hearing on either pure-tone or speech-in-noise measures outperformed their worse hearing counterparts on the MoCA total score. Additionally, females with better hearing were more likely to recall several words on the MoCA delayed recall trial relative to those with worse hearing. Females with NH showed significant correlations between CDTT SRTs and both MoCA and RAVLT scores, while no correlations were observed in males. In contrast, males but not females showed an effect of hearing group on BVMT-R test status. CONCLUSIONS: There were sex-specific differences in auditory-cognitive associations in individuals with MCI. These associations were mostly observed in females and on auditory tests. Potential mechanisms and implications are discussed.

Measurement Properties of the Mayo-Portland Adaptability Inventory (MPAI-4) and Related Measures: A Systematic Review.

OBJECTIVE: To assess the Mayo-Portland Adaptability Inventory-version 4 (MPAI-4) and related measures' measurement properties and the quality of evidence supporting these results; and identify the interpretability and feasibility of the MPAI-4 and related measures. DATA SOURCES: We conducted a systematic review according to COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. We searched 9 electronic databases and registries, and hand searched reference lists of included articles. STUDY SELECTION: Two independent reviewers screened and selected all articles. From 605 retrieved articles, 48 were included. DATA EXTRACTION: Two independent reviewers appraised the evidence quality and rated the extracted classical test theory and Rasch results from each study. DATA SYNTHESIS: We used meta-analysis and COSMIN's approach to synthesize measurement properties evidence (insufficient, sufficient), and the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to synthesize evidence quality (very low, low, moderate, high) by diagnosis (traumatic brain injury [TBI], stroke), and setting (inpatient, outpatient). The MPAI-4 and its subscales are sufficiently comprehensible (GRADE: very low), but there is currently no other content validity evidence (relevance, comprehensiveness). The MPAI-4 and its participation index (M2PI) have sufficient interrater reliability for stroke and TBI outpatients (GRADE: moderate), whereas interrater reliability between TBI inpatients and clinicians is currently insufficient (GRADE: moderate). There is no evidence for measurement error. For stroke and TBI outpatients, the MPAI-4 and M2PI have sufficient construct validity (GRADE: high) and responsiveness (GRADE: moderate-high). For TBI inpatients, the MPAI-4 and M2PI have mixed indeterminant/sufficient construct validity and responsiveness evidence (GRADE: moderate-high). There is 1 study with mixed insufficient/sufficient evidence for each MPAI-4 adaptation (21- and 22-item MPAI, 9-item M2PI) (GRADE: low-high). CONCLUSION: Users can be most confident in using the MPAI-4 and M2PI in TBI and stroke outpatient settings. Future research is needed on reliability, measurement error, predictive validity, and content validity of the MPAI-4 and its related measures across populations and settings.
