**Introduction** The timely and heavily researched technology-based interventions have improved the social participation of older adults with MCI or dementia. Nevertheless, how these interventions modify social participation remains to be seen, and what efficient behaviour change strategies have been utilised. As such, this study aims to conduct a scoping review, identifying the features and social behaviour change strategies behind technology-based interventions that improve social participation for individuals with MCI or dementia. **Methods and Analysis** The scoping review method will be utilised to search journal articles from electronic databases, like PsycINFO, PubMed, MEDLINE, EBSCO, Web of Science and Scopus, and reference lists. Moreover, reports investigating technology-based interventions for adults over 60 with MCI or dementia will be included. Outcomes highlight behaviour change strategies, features, and intervention effectiveness, supporting social participation. The study will entail international research papers in English. Two authors will independently screen titles, abstracts, and full texts utilising Covidence. Disagreements will be resolved through consensus or a third reviewer, and reasons for exclusion will be documented. The process of amalgamating the results will be iterative, allowing the reviewers to refine their presentation of the findings following the data extraction. This iterative approach guarantees that all extracted content can be part of the results, enabling a comprehensive presentation of the findings. This scoping review will offer information on the direction of future research on developing effective technology-based interventions to support social participation for people with MCI or dementia. **Ethics and Dissemination** Ethical approval is not critical since this is a scoping review. The outcome of the study will be published in a peer-reviewed journal. The review will explore design considerations regarding the social participation behaviour changes following technology-based interventions to support practitioners and researchers in developing more effective and user-friendly approaches. **Strengths and Limitations** 1. An exploration of the impact of technology-based intervention on the social participation behaviour of individuals with MCI or dementia. 2. The current reviews on social participation behaviour change strategies and features will be extended and can be applied when designing technology-based interventions. The guidelines supporting Arksey and O’Malley’s framework will be followed without formally measuring the studies’ quality. 3. Possibly relevant findings from articles written in other languages must be excluded, as this review will only consider papers written in English.
