Evaluating the acceptance of ambient assisted living technology (AALT) in rehabilitation: A scoping review

•There is a lack of standardization in the assessment of AALT's acceptance.•The assessment of AALT's acceptance should be considered at an early stage.•More comprehensive approaches are needed for the assessment of AALT’s acceptance.•Further use of mixed-methods research is encouraged in ALL usability research. Ambient assisted living technologies (AALTs) are being used to help community-dwelling older adults (OAs) age in place. Although many AALT are available, their acceptance (perceived usefulness, ease of use, intention to use and actual usage) is needed to improve their design and impact. This study aims to 1) identify AALTs that underwent an acceptance evaluation in rehabilitation contexts, 2) identify methodological tools and approaches to measure acceptance in ambient assisted living (AAL) in rehabilitation research, and 3) summarize AALT acceptance results in existing rehabilitation literature with a focus on peer-reviewed scientific articles. A scoping review was conducted in the following databases: Medline, Embase, Cinahl, and PsycInfo, following the Arksey and O’Malley framework (2009). Four acceptance attributes were extracted: ‘user acceptance’, ‘perceived usefulness’, ‘ease of use’, and ‘intention to use’. Data regarding AALT, participants, acceptance evaluation methods and results were extracted. A total of 21 articles were included among 634 studies retrieved from the literature. We identified 51 AALTs dedicated to various rehabilitation contexts, most of which focused on monitoring OAs’ activities and environmental changes. Acceptance of AALT was evaluated using interviews, questionnaires, focus groups, informal feedback, observation, card sort tasks, and surveys. Although OAs intend to use – or can perceive the usefulness of – AALTs, they are hesitant to accept the technology and have concerns about its adoption. The assessment of AALT acceptance in contexts of rehabilitation requires more comprehensive and standardized methodologies. The use of mixed-methods research is encouraged to cover the needs of particular studies. The timing of acceptance assessment should be considered throughout technology development phases to maximize AALT implementation.
