One of the main objectives for people with intellectual disability (with or without other disabilities) is the ability to perform multistep activities (e.g. preparing a sandwich) without external help from a caregiver. This paper provides a review of studies that evaluated technology systems to teach or support people with intellectual and other disabilities to carry out multistep functional activities through the presentation of single-step instructions. A literature search was performed for English language articles indexed in PubMed, PsycINFO and Web of Science. A narrative synthesis of the articles selected was provided together with a quantitative estimate of the effectiveness of their technology-aided interventions. The latter was carried out via the Percent of Nonoverlapping Data (PND) method. Twenty-six articles met inclusion criteria, with most studies following a single-subject research design (n = 25). The technologies identified were grouped into three categories (self-operated, automatic, and intelligent). Overall, the results are encouraging in that most of the technology solutions reviewed led to positive outcomes in terms of increasing independence of people with intellectual disability in performing relevant multistep activities (average PND score = 96.3%). This review highlights that technology systems designed to present single-step instructions can be effective in teaching or supporting the independent performance of multistep activities by people with intellectual disability with or without other disabilities. Only minimal research exists on development and use of intelligent systems. [ABSTRACT FROM AUTHOR]
