Abstract
Successful care in home health for older adults is heavily dependent on the relationships between care recipients and care providers. A key component of that relationship is trust. To investigate trust in this context, we explored what older care recipients perceive as supporting trust in home care providers. Participants discussed three main categories that support trust in a care provider: professional skills (e.g., safety), personal traits (e.g., honesty), and communication (e.g., content). Insights from the care recipients' perspective are utilized to provide training recommendations for developing trust. For example, care providers should complete tasks in the care recipients' preferred manner.

Abstract
With smartphone use among older populations on the rise, older adults have increased access to health-focused mobile apps. Despite their potential benefits for managing health, currently no guidelines exist for designing these apps specifically for older adult users. We evaluated the usability of one medication management app and two congestive heart failure management apps using cognitive walkthroughs, heuristic analysis, and user testing. We identified design issues that may affect usability for older users, including poor navigation, small button sizes, and inadequate data visualizations. We provide guidelines for developers of health apps to facilitate use by older adults.

Abstract
Breast cancer screening aims to help women by early identification and treatment of cancers that might otherwise be life-threatening. However, breast cancer screening also leads to the detection of some cancers that, if left undetected and untreated, would not have damaged the health of the women concerned. At the time of diagnosis, harmless cancers cannot be identified as non-threatening, therefore women are offered invasive breast cancer treatment. This phenomenon of identifying (and treating) non-harmful cancers is called overdiagnosis. Overdiagnosis is morally problematic as it leads to overall patient harm rather than benefit. Further, breast cancer screening is offered in a context that exaggerates cancer risk and screening benefit, minimises risk of harm and impedes informed choice. These factors combine to create pathogenic vulnerability. That is, breast cancer screening exacerbates rather than reduces women's vulnerability and undermines women's agency. This paper provides an original way of conceptualising agency-supporting responses to the harms of breast cancer overdiagnosis through application of the concept of pathogenic vulnerability.

Abstract
Background and Objectives There is growing evidence of the benefits of computers for older adults. Yet, adoption rates are lower compared with younger adults. Extant theoretical models of technology acceptance are limited in their application to older adults-studies on which these models are based included a limited sample of older adults or none at all; none assessed use of a technology specifically designed for older adults; and most only measured intention to use a technology or short-term use, rather than longer-term use (i.e., adoption). We assessed adoption of a computer system specifically designed for older users, for a diverse sample, over an extended period of time. Research Design and Methods We analyzed archival data from 150 ethnically diverse older adults (65-98 years of age) who participated in the Personal Reminder Information and Social Management (PRISM) randomized controlled trial (Czaja SJ, Boot WR, Charness N, Rogers WA, Sharit J, Fisk AD,…Nair SN. The personalized reminder information and social management system (PRISM) trial: Rationale, methods and baseline characteristics. Contemp Clin Trials. 2015;40:35-46; Czaja SJ, Boot WR, Charness N, Rogers WA, Sharit J. Improving social support for older adults through technology: Findings from the PRISM randomized controlled trial. Gerontologist. 2017;58:467-477). We examined the extent to which attitudes, personal characteristics (e.g., age, gender, and personality), and cognitive abilities predicted mid-term and long-term adoption of a computer system designed for older adults. Results There were individual differences in PRISM use over time. Regression analyses indicated that individual differences in earlier use of the system, executive functioning, and computer efficacy predicted long-term use. Discussion and Implications These data provide insights for broader-based models of technology acceptance to guide design, instruction, and deployment of products for older adults. Specifically, the provision of opportunities to foster efficacy and gain positive experience with computer technologies may play a critical role in the likelihood that older adults adopt such technologies.

Abstract
Background and Objectives Regardless of the increased deployment of technologies in everyday living domains, barriers remain that hamper technology adoption by older adults. Understanding barriers to adoption such as individual differences in attitudes toward computers is important to the design of strategies to reduce age-related digital disparities. Research Design and Methods This article reports a time-sequential analysis of data from the Edward R. Roybal Center on Human Factors and Aging Research and the Center for Research and Education on Aging and Technology Enhancement (CREATE) on computer attitudes among a large (N = 3,917), diverse sample of community-dwelling adults aged from 18 to 98 years. The data were gathered from 1994 to 2013. Results The findings indicated that there are still age disparities in attitudes; older adults report less comfort with and less efficacy about using computers than younger people. We also found a cohort (birth year) effect; attitudes are generally more positive among more recent birth cohorts. Those who have more education and experience with computers also have more positive attitudes. Males generally have more positive attitudes than females; however, the gender difference decreases with increased age. Discussion and Implications Technology affords potential benefits for older people, but lack of uptake in technology clearly puts older adults at a disadvantage in terms of negotiating today's digital world. This article provides insight into attitudinal barriers that may affect on technology uptake among older adults. The findings have implications for the design of technology training programs, design of technology systems, and policy.

Abstract
Objectives Information and communication technology holds promise in terms of providing support and reducing isolation among older adults. We evaluated the impact of a specially designed computer system for older adults, the Personal Reminder Information and Social Management (PRISM) system. Design, Setting, and Participants The trial was a multisite randomized field trial conducted at 3 sites. PRISM was compared to a Binder condition wherein participants received a notebook that contained paper content similar to that contained in PRISM. The sample included 300 older adults at risk for social isolation who lived independently in the community (Mage = 76.15 years). Primary outcome measures included indices of social isolation, social support, loneliness, and well-being. Secondary outcome measures included indices of computer proficiency and attitudes toward technology. Data were collected at baseline and at 6 and 12 months post-randomization. Results The PRISM group reported significantly less loneliness and increased perceived social support and well-being at 6 months. There was a trend indicating a decline in social isolation. Group differences were not maintained at 12 months, but those in the PRISM condition still showed improvements from baseline. There was also an increase in computer self-efficacy, proficiency, and comfort with computers for PRISM participants at 6 and 12 months. Discussion The findings suggest that access to technology applications such as PRISM may enhance social connectivity and reduce loneliness among older adults and has the potential to change attitudes toward technology and increase technology self-efficacy.

Abstract
BACKGROUND Falls are the leading cause of injury-related death in older adults. Due to various constraints, objective fall risk screening is seldom performed in clinical settings. Smartphones offer a high potential to provide fall risk screening for older adults in home settings. However, there is limited understanding of whether smartphone technology for falls screening is usable by older adults who present age-related changes in perceptual, cognitive, and motor capabilities. OBJECTIVE The aims of this study were to develop a fall risk mobile health (mHealth) app and to determine the usability of the fall risk app in healthy, older adults. METHODS A fall risk app was developed that consists of a health history questionnaire and 5 progressively challenging mobility tasks to measure individual fall risk. An iterative design-evaluation process of semistructured interviews was performed to determine the usability of the app on a smartphone and tablet. Participants also completed a Systematic Usability Scale (SUS). In the first round of interviews, 6 older adults participated, and in the second round, 5 older adults participated. Interviews were videotaped and transcribed, and the data were coded to create themes. Average SUS scores were calculated for the smartphone and tablet. RESULTS There were 2 themes identified from the first round of interviews, related to perceived ease of use and perceived usefulness. While instructions for the balance tasks were difficult to understand, participants found it beneficial to learn about their risk for falls, found the app easy to follow, and reported confidence in using the app on their own. Modifications were made to the app, and following the second round of interviews, participants reported high ease of use and usefulness in learning about their risk of falling. Few differences were reported between using a smartphone or tablet. Average SUS scores ranged from 79 to 84. CONCLUSIONS Our fall risk app was found to be highly usable by older adults as reported from interviews and high scores on the SUS. When designing a mHealth app for older adults, developers should include clear and simple instructions and preventative strategies to improve health. Furthermore, if the design accommodates for age-related sensory changes, smartphones can be as effective as tablets. A mobile app to assess fall risk has the potential to be used in home settings by older adults.

Abstract
Roughly, overdiagnosis (ODx) occurs when people are harmed by receiving diagnoses (often accompanied by interventions) that do not benefit them, usually because the diagnosed conditions do not pose a threat to their health. ODx is a theoretical as well as a practical problem as it relates to definitions of disease. Elsewhere, it has been argued that disease is a vague concept and that this vagueness may contribute to ODx. In response, we develop a stipulative or précising definition of disease, for the specific purpose of decreasing or preventing ODx. We call this diseaseODx , aimed at distinguishing cases where it would be beneficial to identify (and treat the condition) from those where diagnosis is more likely to harm than benefit. A preliminary definition of diseaseODx is that X is a diseaseODx iff there is dysfunction that has a significant risk of causing severe harm. This paper examines the 3 concepts in this definition, using a naturalistic account of function, a Feinbergian account of comparative harm, and a probabilistic understanding of risk. We then test the utility of this approach using examples of clinical conditions that are currently overdiagnosed.

Abstract
Despite concerns about the relationships between health professionals and the medical device industry, the issue has received relatively little attention. Prevalence data are lacking; however, qualitative and survey research suggest device industry representatives, who are commonly present in clinical settings, play a key role in these relationships. Representatives, who are technical product specialists and not necessarily medically trained, may attend surgeries on a daily basis and be available to health professionals 24 hours a day, 7 days a week, to provide advice. However, device representatives have a dual role: functioning as commissioned sales representatives at the same time as providing advice on approaches to treatment. This duality raises the concern that clinical decision-making may be unduly influenced by commercial imperatives. In this paper, we identify three key ethical concerns raised by the relationship between device representatives and health professionals: (1) impacts on healthcare costs, (2) the outsourcing of expertise and (3) issues of accountability and informed consent. These ethical concerns can be addressed in part through clarifying the boundary between the support and sales aspects of the roles of device representatives and developing clear guidelines for device representatives providing support in clinical spaces. We suggest several policy options including hospital provision of expert support, formalising clinician conduct to eschew receipt of meals and payments from industry and establishing device registries.

Abstract
Hypertension is the most common chronic disease affecting older adults (65+) in the United States. Unfortunately, many struggle to adhere to their antihypertensive medications as only about half diagnosed with the disease have it controlled. Therefore, there is a need for designing supportive medication management systems to aid this population with their antihypertensive medications, especially using increasingly adopted technologies such as smartphones. The preferences of older adults with hypertension must be considered when designing such systems for this population. Six older adults participated in structured interviews to inform the design of the Medication Education, Decision Support, Reminding and Monitoring System (MEDSReM). Results revealed management needs, design insights, and reminder preferences, as well as mostly positive opinions regarding technology use for medication management. These findings informed the development of MEDSReM with the goal of supporting older adults in successfully managing their antihypertensive medications.

Abstract
Background and Objective As part of the PRISM (Personal Reminder Information & Social Management) randomized field trial, a large group of older adults (N = 150) received a computer system in their home that presented them with the opportunity to play eleven different video games. While researchers have often assessed older adults’ gaming preferences and habits through survey data and focus groups, this trial represented a unique opportunity to study gaming behavior “in the wild” over an entire year. Research Design and Methods We present an exploration of game usage data, individual differences in game preferences and gaming habits, and individual difference predictors of game use. Results Although few individual difference variables consistently predicted game use and preferences, there were clear favorites among the different games, and results demonstrate that given the opportunity and training many older adults may become active and long-term gamers. Discussion and Implications Findings have implications for designing video games that older adults enjoy, supporting enjoyable and meaningful interactions with video games across the life span, and for designing cognitive, social, and health interventions involving games.

Abstract
PURPOSE Technology holds great potential to support Deaf individuals as they age into older adulthood. However, it is unclear to what extent Deaf seniors are using technology in everyday life or whether they experience challenges in using technology. The current study explored technology use among older Deaf adults with regard to attitudes, adoption style, and frequency of use for a wide range of technologies, including assistive technologies (ATs) for persons with hearing loss and general, everyday technologies. MATERIALS AND METHODS We developed a questionnaire that assessed older Deaf adults' use of and experiences with technology. The questionnaire was made available in online and paper versions. Participants (N = 109) were recruited from national conferences and organizations for the Deaf. RESULTS Overall, we found that the older Deaf adults were technology adopters and regularly use and feel comfortable with a variety of devices. However, we also identified a number of technologies that are not being used by this population, including an AT that appears to have become obsolete and technologies that use sound-based alerts. CONCLUSIONS Insights on how older Deaf adults are embracing technology and which devices they are actually using can help policy makers, technology developers, and a range of aging services professionals, better meet the needs of this understudied population. Implications for Rehabilitation: Older Deaf adults use a variety of assistive and everyday technologies and must be considered as consumers and included in the design process. Older Deaf adults are generally positive in their attitudes towards technologies but they are infrequent users of potentially beneficial health technologies, highlighting opportunities for future research and development. Assistive technology for the Deaf (TTY/TTD) appears to have become obsolete with advances in modern communication technologies, which has implications for policy decisions.

Abstract
To successfully deploy a robot into a healthcare setting, it must be accepted by the end users. This study explored healthcare providers' perceptions of a mobile manipulator class personal robot assisting with caregiving tasks for older adult patients. Participants were 14 healthcare providers with an average of 12 years of continuous work experience with older patients. Quantitative and qualitative methods were used. Participants indicated a willingness to use a mobile manipulator robot as an assistant, yet they expressed discretion in their acceptance for different tasks. Benefits of robot assistance noted by participants included saving time, being accurate when conducting medical tasks, and enabling them to be more productive. Participants expressed concern about robots being unreliable, hazardous to patients, and inappropriate for performing some tasks (e.g., those that involve close patient contact). These findings provide insights into healthcare providers' attitudes and preferences for assistance from a mobile manipulator robot.

Abstract
There is a critical need to develop supports for older adults who have a wide range of abilities, including those aging with long-term impairments. Without appropriate support, many individuals will be functioning below optimal levels and will face participation barriers. Technology holds great promise to provide individualized support for a wide range of abilities and for a variety of domains. To ensure technology interventions are designed well and meet research-documented user requirements, we need more specific, actionable models to provide guidance for those developing and designing interventions. In this paper, we present the TechSAge Aging and Disability Model to bridge models from the aging and disability literatures and to disambiguate the population of individuals aging into disability from those aging with disability (i.e., pre-existing impairments). We also present the TechSAge Technology Intervention Model to support aging with pre-existing impairments, which provides direction and touch points for technology interventions. These models reflect the complex and dynamic interaction between age-related changes and an individual's prior capabilities and limitations. We describe the need for these models with respect to filling a gap in the disability and aging literature by highlighting the importance of differentiating between age-related changes and long-term impairments when designing interventions. We also show the need for quantitative and qualitative data to refine the models given complexities of the current state of the literature and survey data. The TechSAge Technology Intervention Model can be used to drive and inform technology redesign and development.

Abstract
Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a "total approach to rehabilitation", combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970's, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program.

Abstract
Partner dance has been shown to be beneficial for the health of older adults. Robots could potentially facilitate healthy aging by engaging older adults in partner dance-based exercise. However, partner dance involves physical contact between the dancers, and older adults would need to be accepting of partner dancing with a robot. Using methods from the technology acceptance literature, we conducted a study with 16 healthy older adults to investigate their acceptance of robots for partner dance-based exercise. Participants successfully led a human-scale wheeled robot with arms (i.e., a mobile manipulator) in a simple, which we refer to as the Partnered Stepping Task (PST). Participants led the robot by maintaining physical contact and applying forces to the robot's end effectors. According to questionnaires, participants were generally accepting of the robot for partner dance-based exercise, tending to perceive it as useful, easy to use, and enjoyable. Participants tended to perceive the robot as easier to use after performing the PST with it. Through a qualitative data analysis of structured interview data, we also identified facilitators and barriers to acceptance of robots for partner dance-based exercise. Throughout the study, our robot used admittance control to successfully dance with older adults, demonstrating the feasibility of this method. Overall, our results suggest that robots could successfully engage older adults in partner dance-based exercise.

Abstract
Current practices of identifying and treating small indolent thyroid cancers constitute an important but in some ways unusual form of overdiagnosis. Overdiagnosis refers to diagnoses that generally harm rather than benefit patients, primarily because the diagnosed condition is not a harmful form of disease. Patients who are overdiagnosed with thyroid cancer are harmed by the psycho-social impact of a cancer diagnosis, as well as treatment interventions such partial or total thyroidectomy, lifelong thyroid replacement hormone, monitoring, surgical complications and other side effects. These harms seem to outweigh any putative benefit of knowing about a cancer that would not have caused problems if left undiscovered. In addition to harms to patients, thyroid cancer overdiagnosis leads to significant opportunity costs at a societal level, due to costs of diagnosis and treatment. Unlike many other overdiagnosed cancers, accurate risk stratification is possible with thyroid cancer. At the individual patient level, use of this risk information might support informed choice and/or shared decision-making, as mandated by clinical ethics frameworks. And this approach might, to some extent, help to reduce rates of diagnosis and intervention. In practice, however, it is unlikely to stem the rising incidence and associated harms and costs of overdiagnosed thyroid cancer, especially in situations where health professionals have conflicts of interest. We argue in this article that thyroid cancer overdiagnosis may be usefully understood as a public health problem, and that some public health approaches will be readily justifiable and are more likely to be effective in minimising its harms.
