This project introduces “successful caregiving” as a new paradigm for understanding the lives of family caregivers of people with dementia, moving beyond binary positive–negative views. Adopting a socio-technical perspective, it develops a multidimensional construct of successful caregiving that integrates health maintenance, psychological wellness, social engagement, and quality care provision. The study theorises how social media engagement and geographic dispersion among family members jointly shape successful caregiving, generating an integrative model to inform future research, support interventions, and the design of IT solutions for dementia care.
