Older People’s Continuance Intention toward Smart Locks: A Quantitative Study Using the Expectation-Confirmation and Task-Technology Fit Models

As the global population ages, smart care solutions like smart locks are increasingly important, yet their adoption by older people remains low. The challenge lies not only in initial adoption but in sustaining long-term use. Most research has focused on pre-adoption behavior, with little attention given to older people’s continuance intention toward smart locks. This study is the first to apply the Expectation-Confirmation and Task-Technology Fit Models to investigate older people’s continuance intention toward smart locks, filling a key gap in the literature. By examining factors influencing continuance intention and integrating the specific characteristics of older people and smart locks, this research develops a comprehensive model.
