DigiSwitch: A Device to Allow Older Adults to Monitor and Direct the Collection and Transmission of Health Information Collected at Home

Home monitoring represents an appealing alternative for older adults considering out-of-home long term care and an avenue for informal caregivers and health care providers to gain decision-critical information about an older adults’ health and well-being. However, privacy concerns about having 24/7 monitoring, especially video monitoring, in the home environment have been cited as a major barrier in the design of home monitoring systems. In this paper we describe the design and evaluation of “DigiSwitch”, a medical system designed to allow older adults to view information as it is collected about them and temporarily cease transmission of data for privacy reasons. Results from a series of iterative user studies suggest that control over the transmission of monitoring data from the home is helpful for maintaining user privacy. The studies demonstrate that older adults are able to use the DigiSwitch system to monitor and direct the collection and transmission of health information in their homes, providing these participants with a way to simultaneously maintain privacy and benefit from home monitoring technology.

Use of seal-like robot PARO in sensory group therapy for older adults with dementia

This work presents the preliminary results of an eight- week study of the seal-like robot PARO being used in a sensory therapy activity in a local nursing home. Participants were older adults with different levels of cognitive impairment. We analyzed participant behaviors in video recorded during the weekly interactions between older adults, a therapist, and PARO. We found that PAROs continued use led to a steady increase in physical interaction between older adults and the robot and an increasing willingness among participants to interact with it.

Situated Analysis of Interactions between Cognitively Impaired Older Adults and the Therapeutic Robot PARO

In order to explore the social and behavioral mechanisms behind the therapeutic effects of PARO, a robot resembling a baby seal, we conducted an eight-week-long study of the robots use in a group activity with older adults in a local retirement facility. Our research confirms PAROs positive effects on participants by increasing physical and verbal interaction as evidenced by our behavioral analysis of video recorded interactions. We also analyzed the behavioral patterns in the group interaction, and found that the mediation of the therapist, the individual interpretations of PARO by different participants, and the context of use are significant factors that support the successful use of PARO in therapeutic implementations. In conclusion, we discuss the importance of taking the broader social context into account in robot evaluation.

Technology: Education and Training Needs of Older Adults.

The impact of the global aging of the population on social, economic, political, and health care institutions is unequaled. Parallel to this, evolving developments in technology promise opportunities for sales and product development to support positive aging. Older adults are excited to utilize technologies that they perceive as practical. However, age, education, technical knowledge, and technological anxiety affect interest in new technologies, creating a technology divide. Providing more accessible and relevant technologies for todays older adults may make the technology more universally accessible. This article reports the results of a survey on technology and education among a sample of 77 adults between the ages of 52 and 92 who attended a week-long lifelong-learning event at Indiana University. Familiarity with technology, age, education, and gender were found to be correlated with familiarity with new technologies as well as operating and shopping for new electronic devices.

Observational study of naturalistic interactions with the socially assistive robot PARO in a nursing home

To explore the development and maintenance of human-robot interaction (HRI) in a real-world setting, we conducted a three-month long field study with the socially assistive robot PARO in a nursing home. We placed PARO a public area in the institution and observed naturally occurring interactions of nursing home residents, staff, and visitors with the robot. We collected both quantitative (on-site behavioral coding and interactor counts) and qualitative (observational field notes) data. The results of behavioral analysis complemented with information from our field notes show that interaction with PARO was often not spontaneous and that mediation from staff and family members was integral to successful interactions between residents and PARO. We also observed that individual interactors engaged with the robot in diverse ways based on their needs. We conclude by discussing design and methodological implications for in situ HRI studies.

Needs and Concerns of Family Caregivers of Persons With Type 2 Diabetes: An Integrated Review of Cross-cultural Literature With Implications for the American Indian Population.

Purpose The purposes of this review were to identify the needs and concerns of family caregivers of persons with type 2 diabetes and to develop recommendations for future research on family caregivers of American Indians with type 2 diabetes. Searching the Cumulative Index to Nursing and Allied Health, Ovid, and PubMed, an extensive literature review was conducted using 10 search terms for articles published from 1990 to 2013. References of retrieved studies were also searched. Conclusions On the basis of the search criteria, 6 studies exploring the needs and concerns of family caregivers of persons with type 2 diabetes were identified. Findings were placed in 5 predetermined categories derived from Bakas et al’s needs and concerns framework: (1) finding information and resources related to type 2 diabetes, (2) dealing with the emotions and behaviors of the care recipient, (3) providing physical care, (4) providing instrumental care, and (5) dealing with one’s own personal responses to caregiving. The cross-cultural literature helped identify common ground and specific literature about the experiences of American Indian caregivers. Further research is needed on the needs of caregivers of persons with type 2 diabetes, particularly those in the Native American and other minority populations. Findings can be used to develop interventions to improve outcomes for these caregivers.

Development and Psychometric Testing of the Diabetes Caregiver Activity and Support Scale

Purpose The purpose of this study was to develop and psychometrically test the Diabetes Caregiver Activity and Support Scale (D-CASS), a measure of how difficult or easy caregiver activity and supportive behaviors are for family caregivers of persons with type 2 diabetes (T2DM). Methods Internal consistency reliability, test-retest reliability, criterion-related validity, and construct validity were examined in 101 family caregivers of persons with T2DM. Participants were recruited using study brochures distributed at a large hospital in the Midwest and at statewide American Indian Pow Wows. Additionally, study brochures were available via a link on Facebook. Data collection occurred by telephone, face-to-face, or through Facebook using measures with evidence of reliability and validity. Family caregivers were predominately female (82.2%), spouses (50.2%), and American Indian (17%), African American (24%), or white (55%). Data were analyzed using descriptive statistics and psychometric analyses. Results The psychometric analyses resulted in an 11-item D-CASS with evidence of internal consistency reliability (alpha = .82) and test-retest reliability. Evidence of construct validity was obtained using 3 hierarchical multiple regressions guided by a conceptual model. Factor analysis supported the unidimensionality of the D-CASS. Conclusion The 11-item D-CASS is a brief and easy to administer instrument that has evidence of reliability and validity in family caregivers of persons with T2DM.
