Objectives When we think of technology-savvy consumers, older adults are typically not the first persons that come to mind. The common misconception is that older adults do not want to use or cannot use technology. But for an increasing number of older adults, this is not true (Pew Internet and American Life Project, 2003). Older adults do use technologies similar to their younger counterparts, but perhaps at different usage rates. Previous research has identified that there may be subgroups of older adults, “Silver Surfers”, whose adoption patterns mimic younger adults (Pew Internet and American Life Project, 2003). Much of the previous research on age-related differences in technology usage has only investigated usage broadly -- from a “used” or “not used” standpoint. The present study investigated age-related differences in overall usage of technologies, as well as frequency of technology usage (i.e., never, occasional, or frequent). Methods The data were gathered through a questionnaire from younger adults (N=430) and older adults (N=251) in three geographically separate and ethnically diverse areas of the United States. Results We found that younger adults use a greater breadth of technologies than older adults. However, age-related differences in usage and the frequency of use depend on the technology domain. Conclusion This paper presents technology usage and frequency data to highlight age-related differences and similarities. The results provide insights into older and younger adults’ technology-use patterns, which in turn provide a basis for expectations about knowledge differences. Designers and trainers can benefit from understanding experience and knowledge differences.

In recent years, there have been national and international policy advances around capacity and decision-making and an apparent burgeoning rights-based approach to the issue, all of which have the potential to impact on the experience for people with dementia in Ireland. There is little evidence however on whether these policies and principles are being translated into practice and whether traditional paternalistic approaches to decision-making are being challenged. To gain insight into current practice, research was undertaken with social workers working with older people in Ireland; reporting on the involvement of people living with dementia in care-planning processes. Data collection included a mixed method approach; an on-line survey of social workers from across the country who reported on their open caseload during the month of June 2015 (N = 38 social workers reporting on the experiences of 788 older people, of which 39% of older people had a formal diagnosis of dementia). In addition, semi-structured telephone interviews were conducted with social workers working in the nine Community Health Organisation areas (N = 21). Findings show that people with dementia were high users of social work services, accounting for 44.5% of the client group. Social workers reported that there were no standardised approaches to how Health and Social Care Professionals involved people with dementia in care planning and decision-making. Overall, people with dementia were more likely to be excluded from decision-making processes due to (i) assumptions that they lacked capacity, (ii) family members preferences that the person was not involved, (iii) communication difficulties, (iv) time constraints, (v) little or no opportunity given or (vi) the person delegated decision-making to others. Good practices were identified through multidisciplinary team approaches and formal care planning meetings. This research highlights variability in how people with dementia participate in decision-making around their care. It sheds light on existing barriers which challenge the full implementation of the Irish Assisted Decision-Making legislation; highlighting the need for appropriate guidance and education for Health and Social Care Professionals. The findings also show that family dynamics and existing relationships can play a role in how people with dementia participate and are involved. To ensure consistent opportunities for participation, effective practices and approaches to supporting the participation of people living with dementia in care planning needs to be developed and rolled out in all care settings through increased training and adoption of standardised approaches.

Technology designers must understand relevant prior knowledge in a target user population to facilitate adoption and effective use. To assess prior knowledge used in naturalistic settings, we systematically collected information about technologies used over 10-day periods from older adults with high and low technology experience and younger adults. Technology repertoires for younger adults and high technology older adults were similar; differences reflected typically different needs for kitchen and health care technologies between the age groups. Technology repertoires for low-technology older adults showed substantial technology usage in many categories. Lower usage compared to high-tech older adults for each category was limited primarily to PC and Internet technologies. Experience differences suggest preferences among low-technology older adults for basic technology usage and for working with people rather than technologies.Participants in all groups were generally successful using their everyday technologies to achieve their goals. Prior knowledge was the most common attribution for success, but external information was also commonly referenced. Relevant prior knowledge included technical, functional, strategy, and self knowledge. High tech older adults did not report more problems than younger adults, but they did attribute more problems to insufficient prior knowledge. Younger adults attributed more problems to interference from prior knowledge. Low-tech older adults reported fewer problems, typically attributing them to insufficient prior knowledge or product/system faults. We discuss implications for further research and design improvements to increase everyday technology success and adoption for high-tech and low-tech older adults. ACM Reference Format:O'Brien, M.

This qualitative study used data from eight focus groups involving 58 people aged over 65 years in both urban and rural settings across Northern Ireland and the Republic of Ireland. Following training, four older people assisted in facilitation and analysis as peer researchers. Increasing lack of respect within society was experienced as abusive. The vulnerability of older people to abuse was perceived as relating to the need for help and support, where standing up for themselves might have repercussions for the person's health or safety. Emotional abusiveness was viewed as underpinning all forms of abuse, and as influencing its experienced severity. Respondents' views as to whether an action was abusive required an understanding of intent: some actions that professionals might view as abusive were regarded as acceptable if they were in the older person's best interests. Preventing abuse requires a wide-ranging approach including rebuilding respect for older people within society. Procedures to prevent elder abuse need to take into account the emotional impact of family relationships and intent, not just a description of behaviors that have occurred.
