The Impact of Assistive Device Use on Disability and Depression Among Older Adults With Age-Related Vision Impairments

BCLA CLEAR Presbyopia: Epidemiology and impact

The global all-ages prevalence of epidemiologically-measured 'functional' presbyopia was estimated at 24.9% in 2015, affecting 1.8 billion people. This prevalence was projected to stabilise at 24.1% in 2030 due to increasing myopia, but to affect more people (2.1 billion) due to population dynamics. Factors affecting the prevalence of presbyopia include age, geographic location, urban versus rural location, sex, and, to a lesser extent, socioeconomic status, literacy and education, health literacy and inequality. Risk factors for early onset of presbyopia included environmental factors, nutrition, near demands, refractive error, accommodative dysfunction, medications, certain health conditions and sleep. Presbyopia was found to impact on quality-of-life, in particular quality of vision, labour force participation, work productivity and financial burden, mental health, social wellbeing and physical health. Current understanding makes it clear that presbyopia is a very common age-related condition that has significant impacts on both patient-reported outcome measures and economics. However, there are complexities in defining presbyopia for epidemiological and impact studies. Standardisation of definitions will assist future synthesis, pattern analysis and sense-making between studies.

Perceived Challenges and Emotional Responses in the Daily Lives of Older Adults With Disabilities: A Text Mining Study

This study explored the daily challenges and emotional reactions experienced by older adults living with various disabilities, employing both traditional and text mining approaches to ensure rigorous interpretation of qualitative data. In addition to employing a traditional qualitative data analysis method, such as thematic analysis, this paper also leveraged a text mining approach. By utilizing topic modeling and sentiment analysis, the study attempted to mitigate potential researcher bias and diminishes subjectivity in interpreting qualitative data. The findings indicated that older adults with visual impairments predominantly encountered challenges related to navigation, technology utilization, and online shopping. Individuals with hearing impairments chiefly struggled with communicating with healthcare providers, while those with mobility impairments face significant barriers in public participation and managing personal hygiene, such as showering. A prevailing sentiment of negative emotional states was identifiable among all participant groups, with those having visual impairments exhibiting more pronounced negative language patterns. The challenges perceived by participants varied depending on the types of disabilities they have. This study can serve as a valuable reference for researchers interested in a mixed-method strategy that combines conventional qualitative analysis with machine-assisted text analysis, illuminating the varied daily experiences and needs of the older adult population with disabilities.

Older Adults and New Technology: Mapping Review of the Factors Associated With Older Adults' Intention to Adopt Digital Technologies

BACKGROUND

Ongoing advancements in digital solutions support older adults' healthy aging and well-being. However, a unified synthesis of sociodemographic, cognitive, attitudinal, emotional, and environmental factors that influence older adults' intention to use these new digital technologies is still lacking. Understanding the salient factors that influence older adults' intention to use digital technologies will help to ensure that technology is developed appropriately and contextually. This understanding is also likely to contribute to developing technology acceptance models specifically for the aging generation, by reorganizing principles and constructing objectivity criteria for future research studies.

OBJECTIVE

This review aims to identify the key factors associated with older adults' intention to use digital technologies and to provide a comprehensive conceptual framework to describe the relationships between these key factors and older adults' intention to use digital technologies.

METHODS

A mapping review was conducted using 9 databases from inception to November 2022. Articles were selected for review if they had an evaluative component of older adults' intention to use digital technologies. Three researchers independently reviewed the articles and extracted the data. Data synthesis was performed via narrative review and quality appraisal was measured using 3 different tools based on each article's study design.

RESULTS

We identified a total of 59 articles investigating older adults' intention to use digital technologies. The majority (40/59, 68%) of articles did not use an existing framework or model for technology acceptance. Studies mostly adopted a quantitative research design (27/59, 46%). We found 119 unique factors reported to influence older adults' intention to use digital technologies. These were categorized into 6 distinct themes: Demographics and Health Status, Emotional Awareness and Needs, Knowledge and Perception, Motivation, Social Influencers, and Technology Functional Features.

CONCLUSIONS

Given the importance of global demographic change toward an aging society, there is surprisingly limited research on the factors that influence older adults' intention to use digital technologies. Our identification of the key factors across different types of digital technology and models supports the future integration of a comprehensive perspective encompassing environmental, psychological, and social determinants for older adults' intention to use digital technologies.

Biological factors influencing depression in later life: role of aging processes and treatment implications

Late-life depression occurring in older adults is common, recurrent, and malignant. It is characterized by affective symptoms, but also cognitive decline, medical comorbidity, and physical disability. This behavioral and cognitive presentation results from altered function of discrete functional brain networks and circuits. A wide range of factors across the lifespan contributes to fragility and vulnerability of those networks to dysfunction. In many cases, these factors occur earlier in life and contribute to adolescent or earlier adulthood depressive episodes, where the onset was related to adverse childhood events, maladaptive personality traits, reproductive events, or other factors. Other individuals exhibit a later-life onset characterized by medical comorbidity, pro-inflammatory processes, cerebrovascular disease, or developing neurodegenerative processes. These later-life processes may not only lead to vulnerability to the affective symptoms, but also contribute to the comorbid cognitive and physical symptoms. Importantly, repeated depressive episodes themselves may accelerate the aging process by shifting allostatic processes to dysfunctional states and increasing allostatic load through the hypothalamic-pituitary-adrenal axis and inflammatory processes. Over time, this may accelerate the path of biological aging, leading to greater brain atrophy, cognitive decline, and the development of physical decline and frailty. It is unclear whether successful treatment of depression and avoidance of recurrent episodes would shift biological aging processes back towards a more normative trajectory. However, current antidepressant treatments exhibit good efficacy for older adults, including pharmacotherapy, neuromodulation, and psychotherapy, with recent work in these areas providing new guidance on optimal treatment approaches. Moreover, there is a host of nonpharmacological treatment approaches being examined that take advantage of resiliency factors and decrease vulnerability to depression. Thus, while late-life depression is a recurrent yet highly heterogeneous disorder, better phenotypic characterization provides opportunities to better utilize a range of nonspecific and targeted interventions that can promote recovery, resilience, and maintenance of remission.

Positive feedback loop between vision-related anxiety and self-reported visual difficulty

BACKGROUND

Patients with Inherited Retinal Diseases typically experience progressive, irreversible vision loss resulting in low vision and blindness. As a result, these patients are at high risk for vision-related disability and psychological distress, including depression and anxiety. Historically, the relationship between self-reported visual difficulty (encompassing metrics of vision-related disability and quality of life, among others) and vision-related anxiety has been regarded as an association and not a causal relationship. As a result, there are limited interventions available that address vision-related anxiety and the psychological and behavioral components of self-reported visual difficulty.

MATERIALS AND METHODS

We applied the Bradford Hill criteria to evaluate the case for a bidirectional causal relationship between vision-related anxiety and self-reported visual difficulty.

RESULTS

There is sufficient evidence to satisfy all nine of the Bradford Hill criteria of causality (strength of association, consistency, biological gradient, temporality, experimental evidence, analogy, specificity, plausibility, and coherence) for the relationship between vision-related anxiety and self-reported visual difficulty.

CONCLUSIONS

The evidence suggests that there is a direct positive feedback loop-a bidirectional causal relationship-between vision-related anxiety and self-reported visual difficulty. More longitudinal research on the relationship between objectively-measured vision impairment, self-reported visual difficulty, and vision-related psychological distress is needed. Additionally, more investigation of potential interventions for vision-related anxiety and visual difficulty is needed.

Impact of assistive devices use on levels of depression in older adults: Evidence from China

The purpose of this study is to evaluate the effect of assistive devices on the level of depression among older adults. Using data from the 2015 and 2018 waves of China Health and Retirement Longitudinal Studies (CHARLS), we analysed this effect through the PSM-DID model and verified the mechanism of the effect through Hayes' mediating effect model. The results showed that assistive devices increased depression levels in older adults. Moreover, there were significant differences among different groups of older adults. The use of assistive devices in developed areas, women, people under 75 years old, and socially active older people had a deeper impact on the level of depression. Differences in the type and number of assistive devices used also affect the level of depression in older people. Furthermore, assistive devices use in older adults increases depression levels by decreasing health satisfaction. This study provides new evidence to explore the relationship between the use of assistive devices and depression levels in older adults. Meanwhile, our research illustrates the importance of developing products and services with age-friendly technology.

Everyday visual demands of people with low vision: A mixed methods real-life recording study

Research has demonstrated that low vison aids (LVAs) can have a positive impact on the functional sight of those living with sight loss. Step changes in technology are now enabling new wearable LVAs with greater potential than those available previously. For these novel devices to receive increased acceptance and therefore adoption by those with sight loss, visual task demands have to be understood more clearly in order to enable better alignment between device design and user requirements. The aim of this study was to quantify these requirements. Thirty-two participants aged 18 to 87 wore a spectacle-mounted video camera to capture and narrate all everyday situations in which they would use a “perfect” sight aid during 1 week. Captured scenes were analyzed through categorization and computational image analysis. Results showed large variation in activities and lifestyles. Participants reported no available sight aid or coping strategy for 57% of the recorded activities. Reading made up 49% of all recorded tasks, the other half comprising non-textual information. Overall, 75% of captured activities were performed ad hoc (duration of 0–5 minutes), 78% occurred indoors, 58% occurred at home, 48% were lit by natural light, 68% included the object of interest within reach, and 69% required a single focus plane only. Around half of captured objects of interest had a size of 2 degrees visual angle (2.08 logarithm of the minimum angle of resolution [logMAR]) or smaller. This study highlights the need for a sight aid that can make both textual and non-textual scenes accessible while offering flexibility to accommodate individual lifestyles.

The Impact of Late-Life Disability Spectrum on Depressive Symptoms: A Fixed-Effects Analysis of Panel Data

OBJECTIVES

This study examines the impact of a previously validated disability spectrum that accounts for compensatory strategies on depressive symptoms in older adults.

METHODS

This study was a secondary data analysis of 2011 through 2018 surveys from the National Health and Aging Trends Study (N = 7,609). The disability spectrum was categorized using a 5-level hierarchical scheme: fully able, successful accommodation, reduced activity, difficulty, and assistance for 12 mobility, self-care, and household activities. The individual fixed-effects panel model was used to examine the impact of this disability spectrum on depressive symptoms.

RESULTS

Depressive symptoms rose progressively with each successive category on the disability spectrum in descriptive analyses. In fixed-effects models, moving from "fully able" to "successful accommodation" was not associated with significant changes in depressive symptoms; this result held for all self-care and mobility activities. Moving from "fully able" to "reduced activity" was associated with a significant increase in depressive symptoms for 3 household activities (doing laundry, making hot meals, and shopping for groceries) but not for paying bills/banking or keeping track of medications. Going up 2 or more stages above "fully able" on the disability spectrum was associated with a significant increase in depressive symptoms across all 12 activities.

DISCUSSION

While limitations in a range of daily activities have harmful effects on mental health, using compensatory strategies that do not erode one's perception of autonomy can help older adults cope with the psychological detriments of late-life disability.

Visual Impairment and Mental Health: Unmet Needs and Treatment Options

Purpose

An estimated 2.2 billion people are visually impaired worldwide. Given that age-related vision loss is a primary cause of vision impairment, this number is projected to rise with increases in average lifespan. Vision loss often results in significant disability and is associated with a substantial economic burden, reduced quality-of-life, concurrent medical issues, and mental health problems. In this review, the mental health needs of people with vision impairment are examined.

Patients and methods

A review of recent literature on mental health outcomes and current treatments in people with visual impairment was conducted.

Results

Considerable data indicate that rates of depression and anxiety are elevated among people with visual impairments. Moreover, individuals of lower socioeconomic status may be at increased risk for vision impairment and subsequent mental health problems. Existing psychosocial interventions for improving mental health in people with visual impairment show some promise, but are limited by low adherence and lack generalizability.

Conclusion

In order to improve outcomes, a better understanding of the mechanisms linking visual impairment and poor mental health is needed. It will also be essential to develop more effective interventions and expand access to services to improve the detection and treatment of mental health problems in this population.

First-Time Experience in Owning a Dog Guide by Older Adults with Vision Loss

Introduction:

In spite of the vast amount of literature on pet therapy and dog companionship, limited studies exist on older adults with vision loss and the experience of owning a dog guide. The purpose of this study is to explore the facilitators and barriers of first-time ownership and utilization of a dog guide as experienced by older adults with vision loss.

Methods:

Data were gathered among seven participants using open-ended semistructured telephone interviews. Participants described their experiences related to owning a dog guide. Using phenomenological analysis, themes were extracted from verbatim transcriptions.

Results:

Through constant comparison methods, five themes emerged: increased responsibilities for new dog guide owners, changes in habits and routines, quick human–dog guide bonding, increase in community integration, and enhancement of autonomy through dog guide ownership.

Discussion:

The study results suggest that obtaining a dog guide increased the older adults with vision loss everyday engagement in community activities. The increased confidence in independent mobility may have led participants to engage in activities in unfamiliar environments, thus improving their autonomy, self-esteem, and physical abilities. These changes resulted in increased feelings of independence and freedom for the older adults with vision loss. Participants also revealed positive changes in their daily habits. Due to the increased physical ability and motivation needed to complete activities, making adjustments to owning a dog guide became easier. Furthermore, a human–dog guide bond was prevalent among all seven participants.

Implications for practitioners:

Themes extracted provide health practitioners and dog guide organizations insight into how owning dog guides may empower older adults with vision loss.

The use of functional performance tests by primary health-care providers to determine walking ability with and without awalking device in community-dwelling elderly

Background: Primary health-care (PHC) providers are important for community involvement in health promotion and prevention efforts, particularly today that the number of elderly is increasing dramatically. The use of a standard practical measure would help in promoting the effectiveness of referral and monitoring processes. Objectives: To investigate the use of functional performance tests in terms of the appropriate cutoff point to determine walking ability with and without a walking device in community-dwelling elderly, and reliability of the tests when used by PHC providers. Methods: Community-dwelling people aged 65 years or older who walked with or without a walking device (n = 309) were interviewed and assessed for information related to the use of a walking device in daily living. Then, they were randomly assessed for their functional ability using the Timed Up and Go Test (TUG), Five Times Sit-to-Stand Test (FTSST), and the 10-Meter Walk Test (10MWT). PHC providers, including a physical therapist, village health volunteer, and a caregiver, assessed 30 participants' functional performances, to address rater reliability of the tests. Results: The findings suggested that outcomes of the tests (TUG < 12 s, FTSST < 15 s, and 10MWT > 0.8 m/s) can indicate the ability of walking without a walking device of the participants. These tests could be used by PHC providers, except for the FTSST by a caregiver. Conclusions: The findings offer a clear cutoff point for promoting the involvement of PHC providers and the standardization of a screening, monitoring, and referral process among many clinical and community settings.

Methods to evaluate perspectives of safety, independence, activity, and participation in older persons using welfare technology. A systematic review

Purpose: To conduct a systematic review of existing methods to evaluate the individual aspects of welfare technology from the perspectives of independence, safety, activity, and participation. Furthermore, the study aimed to describe outcomes that have been the focus of previous research to evaluate individual aspects of welfare technology in older persons living in ordinary housing. Materials and methods: A systematic literature review in PubMed, CINAHL Plus, PsycINFO, Scopus, and Web of Science. Studies selected were those that explored the use of assistive and welfare technology devices from older persons' perspectives, and which considered the concepts of independence, safety, activity and participation, and quality of life. Results: A broad spectrum of instruments was applied in the studies. For independence, three questionnaires were used in the identified studies. For safety, one instrument was used in two versions. To study activity and participation as well as quality of life, several scales were used. Additionally, several studies included qualitative approaches for evaluation, such as interviews, or posed one or more questions regarding the effects of welfare technology. Conclusions: The integration of digital assistive and welfare technology should be based on the needs of older persons, and those needs must be assessed using reliable and relevant instruments. The heterogeneity of the target group, i.e., older persons, together with the fact that assessments must give consideration to identifying goals, obstacles, and risks as well as users' preferences, implies a person-centred approach.Implications for rehabilitationThe integration of digital assistive and welfare technology should be based on older persons' needs, and those needs must be assessed using reliable and relevant instruments.The heterogeneity of the target group, i.e. older persons, together with the fact that assessments must give consideration to identifying goals, obstacles and risks as well as users' preferences, implies a person-centred approach.The ideal would be one coherent model that explores the use of digital assistive and welfare technology from the individual, economic as well as organisational dimensions. This would cover the different needs and expectations of various stakeholders, including economic and organisational, but also the needs of the older person.

Understanding adherence to assistive devices among older adults: a conceptual review

Purpose: The aim of this study was to identify and examine how existing literature has conceptualized adherence to assistive devices (ADs) among older adults. Methods: English articles were searched in MEDLINE, PubMed, and CINAHL (January 1990 to October 2017) for the key words "acceptance", "adherence", "assistive devices", "compliance", "concept," and relevant synonyms. Bibliographies of selected articles were also examined. Articles were analyzed if the following conditions were met conjointly: (1) attempted to define or conceptualize adherence to some degree; (2) were concerned with any AD for older adults; (3) were concerned with adults aged 65 years or older. Results: Sixteen of the 484 articles were included. Adherence to ADs among older adults seemed to be conceptualized under three core themes: psychological, contextual, and functional factors; each with their own unique considerations related to adherence that are analyzed in this study. Conclusion: This review identified a large gap in knowledge about adherence to ADs. Adherence is multi-factorial and highly specific to the individual's circumstances and their relationship with their health care practitioner. Further empirical research should focus on how the three core themes of adherence interact with and influence each other. Implications for rehabilitation Health care professionals who assess for, and recommend ADs should foster a shared decision-making relationship with their clients This review identifies some of the key themes that practitioners should consider when developing and implementing AD regimens with older adults Conceptualizing AD adherence among older adults will help improve monitoring of and quality of care for AD users.

Low vision services: a practical guide for the clinician

Low vision has been defined by best-corrected visual acuity worse than 20/40 in the better eye, substantial visual field loss, or substantial loss of contrast sensitivity that cannot be corrected by refraction, medical treatment, or surgery. In the United States, low vision is most commonly caused by age-related macular degeneration, glaucoma, and diabetic retinopathy. Most patients with low vision are elderly, although patients of all ages – including pediatric patients – may be affected. Low vision may decrease a patient’s quality of life substantially, leading to emotional distress and possibly depression. Low vision specialists aim to maximize the remaining vision of a patient by providing optical aids, orientation and mobility training, psychosocial support, and other methods of rehabilitation. Innovations in technology and devices offer additional options in low vision rehabilitation. Clinicians should consider referral to low vision specialists when a patient has difficulty with reading, mobility, driving, recognizing faces, or suffers from emotional distress due to low vision. Early referral may lead to improved outcomes.

The Effect of the Usage of Computer-Based Assistive Devices on the Functioning and Quality of Life of Individuals who are Blind or have low Vision

Introduction

The Israel Ministry of Social Affairs and Social Services subsidizes computer-based assistive devices for individuals with visual impairments (that is, those who are blind or have low vision) to assist these individuals in their interactions with computers and thus to enhance their independence and quality of life. The aim of this study was to examine the effect of computer usage on the quality of life of computer-based assistive device users, and to evaluate their capacity to carry out computer-based tasks.

Methods

The study was conducted between the years 2013 and 2015. Questionnaires were provided to 96 randomly sampled individuals with visual impairments. These questionnaires were designed to collect information about the quality of life, types and frequency of computer use, satisfaction with the assistive devices, and the effects of computer-based assistive device usage on the participants’ lives. In addition, the study evaluated participants’ performance in tasks such as e-mail use, Internet surfing, and the use of Microsoft Word; participants performed these tasks on their personal computers. The research sample accounts for about 10% of visually impaired persons in Israel.

Results

Findings suggest that participants use computer-based assistive devices frequently (four hours a day on average), primarily for leisure (three hours on average). Participants also report high satisfaction with their devices (mean of 3.98 out of the maximum score of 5.00) and indicate that the devices have improved their quality of life (mean 3.67 out of 5.00) and leisure activities (mean 3.68 out of 5.00). Participants display high levels of task performance, especially in the use of Microsoft Word software (mean of 3.47 out of 5.00), and e-mail usage (mean of 3.81 out of 5.00).

Discussion

The findings suggest that most participants use computer-based assistive devices daily and report a positive influence from them on their quality of life and activity.

Implications for practitioners

The study suggests that welfare services and assistance organizations would benefit from subsidizing computer assistive devices for individuals with visual impairments.

Predictors of depression and life satisfaction in visually impaired people

BACKGROUND

Visual impairment can lead loss of functional ability, necessity of accommodations and assistive technologies or having to rely on others for help. This can bring about feelings of sadness, dependency, inadequacy, and fear, which can put a person at risk for depression and affect one's satisfaction with life.

PURPOSE

The aim of this study was to examine the effects of socio-demographic factors, disability-related factors, optimism, pessimism, self-esteem and social support on depression, and life satisfaction in visually impaired people.

METHODS

A total of 94 visually impaired people completed the measures of socio-demographic and disability-related characteristics, optimism and pessimism, self-esteem, social support, depression and life satisfaction, administered by the authors. Correlational and hierarchical regression analysis was used to examine the relations and test the model for predicting depression and life satisfaction.

RESULTS

The results have shown that depression was negatively related to the level of education, optimism, self-liking, self-competence, support from friends, family and coworkers, and positively related to comorbidity and pessimism. Life satisfaction was positively related to education, socio-economic status, optimism, self-liking, self-competence and support from friends, family and coworkers, and negatively to pessimism. Results have further shown that depression levels were predicted by education, comorbidity, optimism and self-liking, and that self-liking mediated the relationship between optimism and depression. Life satisfaction was predicted by optimism, pessimism, self-liking, friends' support, and depression. Further analysis suggested that the path from optimism to life satisfaction goes through self-liking, friends' support, and depression. Pessimism showed indirect effects through self-liking but also had direct effects on life satisfaction.

CONCLUSIONS

Focusing on optimism, pessimism, self-esteem, and social functioning of visually impaired is important in preventing depression and promoting life satisfaction, and should be a part of rehabilitation practices. Implications for Rehabilitation Screening for depression and mental health problems should be a part of rehabilitation process. Changes in the perception of future outcomes should be monitored and addressed throughout rehabilitation process in order to boost realistic optimism and prevent discouragement and hopelessness. Frequent feedback and positive reinforcement about a persons' progress and ability should be given throughout rehabilitation process in order to promote positive view of oneself and prevent self-esteem problems. Visually impaired people should be encouraged to socialise outside of their families and participate in social activities. This can be integrated in rehabilitation process as a part of everyday homework.

Assistive technology unmet needs of independent living older Hispanics with functional limitations

PURPOSE

To identify: (1) the most frequently used assistive technology (AT) by a sample of community-living older Hispanics; (2) their AT needs; (3) the AT that would not be used by the simple; and (4) the factors associated with the willingness to use AT.

MATERIALS AND METHODS

We used a cross-sectional descriptive study design with a purposive sample of 60 individuals 70 years and older living in Puerto Rico. Data collection tools included a socio-demographic questionnaire and the Assistive Technology Card Assessment. We used descriptive statistics to identify the sample AT use and needs, χ² to determine the frequency distribution of the socio-demographic variables and the Spearman's rank correlation coefficient (rho) to describe the strength of the association between these variables and the willingness to use AT devices.

RESULTS

The sample had unmet needs for AT devices for cooking, home tasks and home safety. A higher number of health conditions as well as having low educational levels were associated with willingness to use AT devices.

CONCLUSIONS

Policy implications are discussed supporting the role of rehabilitation professionals, state government and community-based programmes, including the Area Agencies on Aging, in providing culturally relevant AT education and accessibility to assistive devices. Implications for rehabilitations Hispanic older adults with functional limitations living independently in Puerto Rico have unmet needs for AT devices to compensate for physical limitations and increase safety performance, predominantly in instrumental activities of daily living. New policies need to be developed to advocate for increased healthcare coverage of low tech AT devices that could be highly beneficial to older people with functional limitations. Community-based programs administered by the state government, the Area Agencies of Aging, or operated through Medicare need to be developed to provide education, training, loans, purchasing, and delivery of low AT devices that can compensate for older people functional limitations.

Targeted Vision Function Goals and Use of Vision Resources in Ophthalmology Patients with Age-Related Macular Degeneration and Comorbid Depressive Symptoms

Introduction

This study characterizes self-reported functional vision goals and the use of low vision resources (for example, services and devices) in ophthalmology clinic patients with age-related macular degeneration (AMD) and comorbid depressive symptoms.

Methods

From July 2009 to February 2013, we assessed 188 consecutive patients (age 65 +; mean 84.0 years; 70.2% female) with AMD (best corrected distance acuity 20/70 or worse) enrolled in a 12-month randomized clinical trial to test the efficacy of a multi-component intervention that combined low vision optometry and home-based occupational therapy to prevent depression (Low Vision Depression Prevention Trial [VITAL]). A geriatric nurse conducted in-home assessments to measure visual acuity and contrast sensitivity, self-reported functional vision, functional vision goals that were personally important yet difficult to achieve (targeted vision function goals), and the use of low vision resources (defined as services, devices and strategies utilized by low vision patients to compensate for visual deficits). This study reports on baseline data collected prior to randomization.

Results

Only 9.6% of the sample had received formal low vision services. The five most common goals were newspaper reading, leisure and entertainment, computer use, personal communication, and correspondence. Participants engaged in targeted vision function goals less frequently since being diagnosed with AMD, despite using low vision resources and reporting low to moderate difficulty in using them.

Discussion

Few patients with AMD seen in ophthalmology clinics received low vision rehabilitation. Patients who utilized resources engaged in goals less frequently since being diagnosed with AMD.

Implications for practitioners

Patients with AMD are underutilizing low vision rehabilitation resources. Strategies for increasing low vision referrals are suggested.

The Effects of Low-Vision Rehabilitation on Reading Speed and Depression in Age Related Macular Degeneration: A Meta-Analysis

IMPORTANCE

Age related macular degeneration (AMD) is a progressive eye disease that, as of 2015, has affected 11 million people in the U.S. and 1.5 million in Canada causing central vision blindness. By 2050, this number is expected to double to 22 million. Eccentric vision is the target of low-vision rehabilitation aids and programs for patients with AMD, which are thought to improve functional performance by improving reading speed and depression.

OBJECTIVE

This study evaluates the effect of various low-vision rehabilitation strategies on reading speed and depression in patients 55 and older with AMD.

DATA SOURCES

Computer databases including MEDLINE (OVID), EMBASE (OVID), BIOSIS Previews (Thomson-Reuters), CINAHL (EBSCO), Health Economic Evaluations Database (HEED), ISI Web of Science (Thomson-Reuters) and the Cochrane Library (Wiley) were searched from the year 2000 to January 2015.

STUDY SELECTION

Included papers were research studies with a sample size of 20 eyes or greater focused on AMD in adults aged 55 or older with low vision (20/60 or lower).

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers screened and extracted relevant data from the included articles. Standardized mean difference (SMD) was chosen as an effect size to perform meta-analysis using STATA. Fixed- and random-effect models were developed based on heterogeneity.

MAIN OUTCOMES

Reading Speed and Depression Scores.

RESULTS

A total of 9 studies (885 subjects) were included. Overall, a significant improvement in reading speed was found with a SMD of 1.01 [95% CI: 0.05 to 1.97]. Low-vision rehabilitation strategies including micro-perimetric biofeedback, microscopes teaching program significantly improved reading speed. Eccentric viewing training showed the maximum improvement in reading speed. In addition, a non-significant improvement in depression scores was found with a SMD of -0.44 [95% CI: -0.96 to 0.09].

CONCLUSION

A considerable amount of research is required in the area of low-vision rehabilitation strategies for patients with AMD. Based on current research, low-vision rehabilitation aids improve reading speed. However, they do not have a significant effect on depression scores in those 55 and older with AMD.

Anxiety and depression in patients with advanced macular degeneration: current perspectives

Age-related macular degeneration (AMD) - despite advances in prevention and medical treatment options - remains prevalent among older adults, often resulting in functional losses that negatively affect the mental health of older adults. In particular, the prevalence of both anxiety and depression in patients with AMD is high. Along with medical treatment options, low vision rehabilitation and AMD-specific behavioral and self-management programs have been developed and have demonstrated effectiveness in improving the mental health of AMD patients. This article reviews the prevalence of anxiety and depression in patients with advanced AMD, discusses potential mechanisms accounting for the development of depression and anxiety in AMD patients, presents the state-of the-art of available interventions for addressing anxiety and depression in AMD patients, and delineates recommendations for eye care professionals regarding how to screen for these two prevalent mental health problems and how to facilitate appropriate treatment for patients with AMD.

Compensatory Strategies: Prevalence of Use and Relationship to Physical Function and Well-Being

We examine prevalence of four compensatory strategies (assistive devices, receiving help, changing frequency, or method of performance) and their immediate and long-term relationship to well-being. A total of 319 older adults (>70 years) with functional difficulties at home provided baseline data; 285 (89%) provided 12-month data. For 17 everyday activities, the most frequently used strategy was changing method of performance ( M = 10.27 activities), followed by changing frequency ( M = 6.17), assistive devices ( M = 5.38), and receiving help ( M = 3.37; p = .001). Using each strategy type was associated with functional difficulties at baseline ( ps < .0001), whereas each strategy type except changing method predicted functional decline 12 months later ( ps < .0001). Changing frequency of performing activities was associated with depressed mood ( p < .0001) and poor mastery ( p < .0001) at both baseline and 12 months ( ps < .02). Findings suggest that strategy type may be differentially associated with functional decline and well-being although reciprocal causality and the role of other factors in these outcomes cannot be determined from this study.

Activity limitations, use of assistive devices or personal help, and well-being: variation by education

OBJECTIVES

This study examined the associations among self-care or mobility limitations, use of assistive devices or personal help, and well-being while giving special attention to 3 dimensions of well-being and older adults' educational attainment.

METHOD

The analysis was based on 4,456 community-dwelling older adults with self-care or mobility limitations who completed interviews in the first round of the National Health and Aging Trends Study. Path models were estimated to examine the associations among limitations, use of assistive devices or personal help, and 3 dimensions of well-being (positive affect, self-realization, and self-efficacy) for different educational groups of older adults.

RESULTS

Self-care or mobility limitations had a negative association with 3 dimensions of well-being. The use of assistive devices was positively related, but the use of personal help was negatively related to well-being. Older adults with more education demonstrated weaker associations between assistive devices and well-being and stronger inverse associations between personal help and well-being than those with less education.

DISCUSSION

The use of coping strategies to address self-care or mobility limitations is not necessarily associated with better well-being, and education does not seem to play a protective role once limitations develop. More research is needed to unpack population heterogeneity in the association between coping strategies and well-being.

Low vision depression prevention trial in age-related macular degeneration: a randomized clinical trial

PURPOSE

To compare the efficacy of behavior activation (BA) + low vision rehabilitation (LVR) with supportive therapy (ST) + LVR to prevent depressive disorders in patients with age-related macular degeneration (AMD).

DESIGN

Single-masked, attention-controlled, randomized, clinical trial with outcome assessment at 4 months.

PARTICIPANTS

Patients with AMD and subsyndromal depressive symptoms attending retina practices (n = 188).

INTERVENTIONS

Before randomization, all subjects had 2 outpatient LVR visits, and were then randomized to in-home BA+LVR or ST+LVR. Behavior activation is a structured behavioral treatment that aims to increase adaptive behaviors and achieve valued goals. Supportive therapy is a nondirective, psychological treatment that provides emotional support and controls for attention.

MAIN OUTCOME MEASURES

The Diagnostic and Statistical Manual IV defined depressive disorder based on the Patient Health Questionnaire-9 (primary outcome), Activities Inventory, National Eye Institute Vision Function Questionnaire-25 plus Supplement (NEI-VFQ), and NEI-VFQ quality of life (secondary outcomes).

RESULTS

At 4 months, 11 BA+LVR subjects (12.6%) and 18 ST+LVR subjects (23.4%) developed a depressive disorder (relative risk [RR], 0.54; 95% CI, 0.27-1.06; P = 0.067). In planned adjusted analyses the RR was 0.51 (95% CI, 0.27-0.98; P = 0.04). A mediational analysis suggested that BA+LVR prevented depression to the extent that it enabled subjects to remain socially engaged. In addition, BA+LVR was associated with greater improvements in functional vision than ST+LVR, although there was no significant between-group difference. There was no significant change or between-group difference in quality of life.

CONCLUSIONS

An integrated mental health and low vision intervention halved the incidence of depressive disorders relative to standard outpatient LVR in patients with AMD. As the population ages, the number of persons with AMD and the adverse effects of comorbid depression will increase. Promoting interactions between ophthalmology, optometry, rehabilitation, psychiatry, and behavioral psychology may prevent depression in this population.

Change-readiness of the blind: a hospital based study in a coastal town of South India

Purpose:

Blindness is a devastating condition with psychosocial and economic effects. The shortcomings result in a burden to the blind person, the family and society. Rehabilitation of the blind can transform their lives. The aim of this study was to assess the “change-readiness” of the blind to undergo a “change-management”.

Materials and Methods:

The study was a semi-structured pre-tested questionnaire-based study of 50 blind subjects in a medical college hospital. The blind participants were assessed for depression using the Beck Depression Inventory II, for the perceived effect of blindness on family, social life and occupation. The participants were counseled to undergo psychiatric management, vocational training, use blind aids and learn Braille. The willingness of the participants with reasons was assessed using a verbal analogue scale. Pearson Chi-square test, ANOVA and the t-test were used for statistical analysis.

Results:

Over two-thirds of the subjects were depressed. Family life, social life and occupation were perceived to be affected by 44%, 66% and 74%, respectively. Change-readiness scores were low for low vision and blind aids, vocational training, psychiatric management, change of job and learning Braille. The low score was due to the associated taboo, dependence, lack of skills, embarrassment, etc., The most valuable feature was the family cohesiveness.

Conclusion:

The results suggest that there is a need to modify health policy to include blind rehabilitation, to improve visibility of blind rehabilitation centers, to include family members and co-professionals while managing the blind so that we treat the “blind person” and not a “pair of blind eyes”.

[The influence of visual rehabilitation on secondary depressive disorders due to age-related macular degeneration. A randomized controlled pilot study]

BACKGROUND

Age-related macular degeneration (AMD) often leads to visual impairment, loss of reading ability, reduced quality of life and secondary depression. The present study examined if visual rehabilitation has a preventive effect on secondary depression in these patients.

MATERIAL AND METHODS

In a controlled pilot study 20 patients were randomized into 2 groups whereby 9 underwent visual rehabilitation at first examination and 11 received magnifying visual aids only after 3 months. Psychosocial status was assessed by the geriatric depression scale (GDS) and the German version of the Centre for Epidemiologic Studies depression (CES-D) scale (main outcome parameter), cognitive status by the dementia detection test (DemTecT), minimental status (MMS) and quality of life by the National Eye Institute visual function questionnaire (NEI-VFQ 25). Ophthalmological examination included reading speed measurement by standardized texts (International Reading Speed Texts; IReST).

RESULTS

Parameters of the CES-D scale, DemTect and the subitem exercise of social roles of the NEI-VFQ 25 emerged in a divergent manner. Patients of the rehabilitation group became less depressive and improved in cognitive and social abilities and in the control group vice versa. The interactive effect of group and time was statistically significant for all three tests.

CONCLUSIONS

Visual rehabilitation has a positive impact on depression as well as cognitive status and quality of life in patients with AMD. The effects have to be confirmed in future studies with more patients and a longer observation period.

The Vision-Specific Optimization in Primary and Secondary Control (OPS) Scale

OBJECTIVE

To successfully address the challenges of age-related visual impairment in rehabilitation and health care settings, it is crucial to gain a better understanding of the psychological and behavioral adaptations that occur in these populations. The purpose of this study was to modify the Optimization in Primary Secondary Control Scale (OPS) (Heckhausen Schulz and Wrosch 1999) to assess the utilization of lifespan control strategies among older adults with visual impairment.

METHOD

The Optimization in Primary and Secondary Control Scale (OPS) (Heckhausen et al. 1999) was used to develop a vision-specific version of this measure (i.e., VIS-OPS). The VIS-OPS was administered to older adults with recent vision loss (N = 364; Mean age = 82.9 years). Theory-driven confirmatory factor analysis was used to help refine the instrument and confirm the scale's four-factor structure.

RESULTS

Items were removed from three of the four VIS-OPS subscales due to low squared-multiple correlations and poor model fit. Inter-item reliabilities for the resultant subscales ranged from 0.61 to 0.72. The final four-factor model fit the data well (RMSEA = .06, 90% CI .05--.06), with all items loading significantly on their associated factors (i.e. subscales). Correlational analyses provided criterion-related validity for the VIS-OPS with disability and psychosocial functioning measures in the expected directions.

CONCLUSIONS

The VIS-OPS will allow researchers to more systematically and precisely measure control strategy use in reference to specific challenges associated with visual impairment, and may serve as a model for examining control strategy use in the context of other disabilities.

Occupational therapy interventions to improve the reading ability of older adults with low vision: a systematic review

This systematic review of the literature examined available evidence regarding the effectiveness of occupational therapy interventions for improving the reading performance of older adults with low vision. We reviewed 32 studies and found strong evidence supporting low vision programs that included occupational therapy and moderately strong evidence supporting the use of electronic magnification. Moderate evidence supported the influence of illumination on reading ability. Limited evidence was found to support eccentric viewing training and optical magnification. More evidence of higher quality is needed to validate the effectiveness of optical magnifiers, text eccentric viewing, characteristic preferences, and line guides within optical magnification. Additionally, further research is needed to develop a standard low vision rehabilitation program. The results of this review support the need for occupational therapy to be included in low vision rehabilitation. The implications of the findings for occupational therapy practice, research, and education are discussed.

Stepped-care to prevent depression and anxiety in visually impaired older adults--design of a randomised controlled trial

BACKGROUND

Subthreshold depression and anxiety are common in the growing population of visually impaired older adults and increase the risk of full-blown depressive or anxiety disorders. Adequate treatment may prevent the development of depression or anxiety in this high risk group.

METHOD/DESIGN

A stepped-care programme was developed based on other effective interventions and focus groups with professionals and patient representatives of three low vision rehabilitation organisations in The Netherlands and Belgium. The final programme consists of four steps: 1) watchful waiting, 2) guided self-help, 3) problem solving treatment, 4) referral to general practitioner. The (cost-)effectiveness of this programme is evaluated in a randomised controlled trial. Patients (N = 230) are randomly assigned to either a treatment group (stepped-care) or a control group (usual care). The primary outcome is the incidence of depressive and anxiety disorders, measured with the Mini International Neuropsychiatric Interview (MINI).

DISCUSSION

Preventive interventions for depression and anxiety have received little attention in the field of low vision. A stepped-care programme that focuses on both depression and anxiety has never been investigated in visually impaired older adults before. If the intervention is shown to be effective, this study will result in an evidence based treatment programme to prevent depression or anxiety in patients from low vision rehabilitation organisations. The pragmatic design of the study greatly enhances the generalisability of the results. However, a possible limitation is the difficulty to investigate the contribution of each individual step.

Depression in the elderly with visual impairment and its association with quality of life

Background

Visual impairment is more prevalent in the elderly and depression is common in this population. Although many studies have investigated depression or quality of life (QOL) in older adults with visual impairment, few have looked at the association between these two concepts for this population. The aim of this systematized review was to describe the association between depression and QOL in older adults with visual impairment.

Methods

A search was done using multiple electronic databases for studies addressing the relationship between QOL and depression in elders with visual impairment. The concept of QOL was divided into two different approaches, ie, QOL as achievement and QOL as subjective well-being. Comparison of QOL scores between participants with and without depression (Cohen’s d) and correlations between depression and QOL (Pearson’s r) were examined.

Results

Thirteen studies reported in 18 articles were included in the review. Nearly all of the studies revealed that better QOL was moderately to strongly correlated with less severe depressive symptoms (r = 0.22–0.68 for QOL as achievement; r = 0.68 and 0.72 for QOL as subjective well-being). Effect sizes for the QOL differences between the groups with and without depression ranged from small to large (d = 0.17 to 0.95 for QOL as achievement; no data for QOL as subjective well-being).

Conclusion

Additional studies are necessary to pinpoint further the determinants and mediators of this relationship. Considering the high prevalence rate of depression in this community and its disabling effects on QOL, interventions to prevent and treat depression are essential. More efforts are needed in clinical settings to train health care practitioners to identify depressed elders with visual impairment and provide appropriate treatment.

Factors That Influence the Occupational Engagement of Older Adults with Low Vision: A Scoping Review

Introduction:

Prior research has provided occupational therapists with an understanding of the negative impact of low vision on self care, leisure and productivity. In order to guide future low-vision rehabilitation services, an understanding of the factors that influence the occupational engagement of older adults with age-related vision loss (ARVL) is also needed.

Method:

A scoping review of the literature was conducted in order to identify those factors that have been shown to influence the occupational engagement of older adults with ARVL, and to identify future research needs.

Findings:

As identified in this scoping review, five types of factors were shown to influence occupational engagement for older adults with ARVL including: demographic variables, emotional components, behavioural components, diagnostic components, and environmental aspects.

Conclusion:

Although findings pertaining to personal factors can inform practice, few studies explored the influence of environmental factors on occupational engagement. Given that occupation is a result of person-environment transactions, it is important that future research more fully explores environmental influences in order to enable occupational therapists to deliver services that optimize the occupational performance of seniors with ARVL.

Comorbidities and depression in older adults with HIV

Objective To investigate whether the high rates of depression found in older adults living with HIV are associated with the number and types of comorbidities. Methods: The Research on Older Adults with HIV (ROAH) study collected self-reported health data on ~1000 New York City HIV-positive men and women aged 50 years and older. Participants provided data on health problems experienced in the past year and depressive symptomatology (Center for Epidemiological Studies Depression Scale (CES-D)). Data were analysed using a non-parametric test of association and multiple regression analysis. Results: The correlation between CES-D scores and number of comorbidities was significant (r = 0.24). In multivariate analyses, depression remained a significant covariate of the number of comorbid conditions, in addition to female gender, inadequate income, history of drug and alcohol use, AIDS diagnosis and self-rated health. Correlations of depression with specific comorbidities varied. Significant correlations with sensory loss and dermatological problems were observed. Significant correlations existed with heart and respiratory conditions as well as fractures, but the directionality of these cross-sectional relationships is uncertain. Conclusions: The findings suggest the need for further longitudinal research to understand how high rates of depressive symptoms are related to comorbidities. Focussed clinical care that strives to prevent the collapse of the immune system must evolve into an effective treatment strategy for multimorbidities, where HIV is but one of many other chronic illnesses. If the management of depression continues to be a low priority, the older person with HIV may experience an avoidable reduction in life expectancy.

Low vision, ADL and hearing assistive device use among older persons with visual impairments

Assistive devices (AD) have long played an important role in occupational therapy practice as a way of enabling activities of daily living (ADL), but no studies to date have investigated the use of low vision AD among older persons with age-related macular degeneration (AMD) as well as devices for ADL performance and hearing. The purpose of this study was to describe AD users and to investigate the association of AD and ADL. A health promotion program versus an individual program was investigated within a randomised design. The study was based on data from 131 participants, 28-months after intervention. Data on prescribed ADs were examined through medical records and registers. The participants in the health promotion program used low vision AD in combination with ADL devices to a higher degree, whereas participants in the individual program used just optical AD. Greater use of non-optical AD within the individual program and greater use of ADL devices within the health promotion program was weakly associated with higher level of ADL dependence. There was no significant association between the number of low vision AD and having a decreased, a maintained or improved level of dependence at 28 months.

[Quality of life by limited vision in old age: the example of age-related macula degeneration]

Age-related macula degeneration (AMD) is accompanied by considerable consequences regarding the psychosocial quality of life. A considerable body of research literature now indicates, for instance, an increased rate of depression and substantial loss of everyday capabilities in AMD patients. However, inter-individual differences are large and part of the explanation lies in differences in the ability to cope with and detach oneself from aims in life. The negative impact of AMD on the qualify of life is associated with a need for psychosocial support, but this need is barely met at present. A series of studies nevertheless supports the view that successful intervention is possible even with very old patients. In this respect the problems at present have less to do with recognition than with application and implementation.

Psychosocial adaptations to dual sensory loss in middle and late adulthood

Concurrent losses of hearing and vision function, or dual sensory loss, affect a large number of individuals of all ages and particularly older adults. Dual sensory loss may present at any age as a result of genetic defect, accident, injury, disease, or environmental insult; however, most persons develop this condition as a result of age-related disease processes that rarely result in total deafness or blindness. This condition has wide-ranging implications for physical and psychological functioning and quality of life. In this article, we review the prevalence and causes of dual impairment and its effects on functioning for both individuals affected and their families. We examine psychosocial coping and adaptation to this condition using biopsychosocial-spiritual and ecological models and discuss various strategies for coping and adaptation. The impact of larger societal forces on psychosocial adaptation is presented, followed by recommendations for how rehabilitation and other professionals can meet the challenge of dual sensory loss that awaits us with the aging of the population.
