Technology-driven solutions to prompt conversation, aid communication and support interaction for people with dementia and their caregivers: a systematic literature review.

BACKGROUND The impact of dementia for communication skills can result in difficulties in social interactions between people with dementia and their conversation partner, as initiating and maintaining conversations becomes increasingly challenging. The role of technology in enhancing social health and participation for people with dementia is increasing, but the use of technological devices to support social interactions and aid communication quality is still in its infancy. The objective of this literature review is to provide a comprehensive description of technology-driven interventions for people with dementia and their conversation partners to prompt communication and facilitate positive social interactions. METHODS A systematic search was conducted using PubMed, CINAHL and PsycINFO, with titles and abstracts independently screened by two researchers. Quality appraisal of the included studies was assessed using the Mixed Methods Appraisal Tool. RESULTS Of the 18 papers included, the technology most commonly used to facilitate communication and interactions was tablet-computers (n = 7), social robots (n = 5) and computers systems (n = 4). By analyzing the impact of the device(s) for social interaction and communication, four major themes emerged: i) breaking the ice; ii) increased interaction; iii) better understanding of the person with dementia; and iv) reduced pressure for the conversation partner. CONCLUSION While the majority of the included studies are small-scale, they indicate promising findings for the potential of technology to promote interaction in a way that relieves strain on the caregiver, enhances relationships and engages people with dementia in social activities. Rigorous investigation using standard, comparable measurements is needed to demonstrate the effects of technological solutions, as well as to explore and address barriers and potential adverse outcomes.
