Methods to assess the effectiveness and acceptance of information and communication technology-based assistive technology for older adults: a scoping review.

An aging society is a growing challenge for families, social and rehabilitation service providers, and economies. Information and communication technology-based assistive technology can bolster the independence of older adults (65 years and above) and reduce their burden on caregivers. Currently, there is no unified methodology to assess the effectiveness and acceptance of these technologies. The present study undertakes a scoping review to (1) identify and characterize the methods for assessing the acceptability and usability of information and communication technology-based assistive technologies, (2) explore the advantages and disadvantages of the assessment methods, (3) determine the possibilities of combining the assessment methods and (4) define the most commonly used assessment method and set of outcome measures. The literature was searched in MEDLINE, Scopus, IEEE Cochrane and Web of Science bibliographic databases using the keywords defined by reviewers for articles in English published between 2011 and 2021. Of the 1696 matches, 31 met the inclusion criteria. It was found that a combination of different assessment methods was common in outcome measurements. Of the 31 studies, assessment methods were combined in 21 studies and multiple questionnaires were used in 11 studies. The most common technique of outcome measurement was the use of questionnaires (81%), conducting interviews (48%) and recording usability-performance measures (39%). The advantages and disadvantages of the assessment methods could not be determined in the selected studies in this scoping review.

A Technology-Based Intervention to Support Older Adults in Living Independently: Protocol for a Cross-National Feasibility Pilot.

Innovative technologies can support older adults with or without disabilities, allowing them to live independently in their environment whilst monitoring their health and safety conditions and thereby reducing the significant burden on caregivers, whether family or professional. This paper discusses the design of a study protocol to evaluate the acceptance, usability, and efficiency of the SAVE system, a custom-developed information technology-based elderly care system. The study will involve older adults (aged 65 or older), professional and lay caregivers, and care service decision-makers representing all types of users in a care service scenario. The SAVE environmental sensors, smartwatches, smartphones, and Web service application will be evaluated in people's homes situated in Romania, Italy, and Hungary with a total of 165 users of the three types (cares, elderly, and admin). The study design follows the mixed method approach, using standardized tests and questionnaires with open-ended questions and logging all the data for evaluation. The trial is registered to the platform ClinicalTrials.gov with the registration number NCT05626556. This protocol not only guides the participating countries but can be a feasibility protocol suitable for evaluating the usability and quality of similar systems.
