Don’t Stand so Close to Me: Acceptance of Delegating Intimate Health Care Tasks to Assistive Robots

Socially Assistive Robots (SAR) may help improve care delivery at home for older adults with cognitive impairment and reduce the burden of informal caregivers. Examining the views of these stakeholders on SAR is fundamental in order to conceive acceptable and useful SAR for dementia care. This study investigated SAR acceptance among three groups of older adults living in the community: persons with Mild Cognitive Impairment, informal caregivers of persons with dementia, and healthy older adults. Different technology acceptance questions related to the robot and user characteristics, potential applications, feelings about technology, ethical issues, and barriers and facilitators for SAR adoption, were addressed in a mixed-method study. Participants (n = 25) completed a survey and took part in a focus group (n = 7). A functional robot prototype, a multimedia presentation, and some use-case scenarios provided a base for the discussion. Content analysis was carried out based on recorded material from focus groups. Results indicated that an accurate insight of influential factors for SAR acceptance could be gained by combining quantitative and qualitative methods. Participants acknowledged the potential benefits of SAR for supporting care at home for individuals with cognitive impairment. In all the three groups, intention to use SAR was found to be lower for the present time than that anticipated for the future. However, caregivers and persons with MCI had a higher perceived usefulness and intention to use SAR, at the present time, than healthy older adults, confirming that current needs are strongly related to technology acceptance and should influence SAR design. A key theme that emerged in this study was the importance of customizing SAR appearance, services, and social capabilities. Mismatch between needs and solutions offered by the robot, usability factors, and lack of experience with technology, were seen as the most important barriers for SAR adoption.

This study investigated the attitudes and preferences of staff, residents and relatives of residents in a retirement village towards a health-care robot. Focus groups were conducted with residents, managers and caregivers, and questionnaires were collected from 32 residents, 30 staff and 27 relatives of residents. The most popular robot tasks were detection of falls and calling for help, lifting, and monitoring location. Robot functionality was more important than appearance. Concerns included the loss of jobs and personal care, while perceived benefits included allowing staff to spend quality time with residents, and helping residents with self-care. Residents showed a more positive attitude towards robots than both staff and relatives. These results provide an initial guide for the tasks and appearance appropriate for a robot to provide assistance in aged care facilities and highlight concerns. © 2011 The Authors.
