BackgroundThe global aging population necessitates leveraging technology for older adults' independence and mental well-being. Gerontechnology, tailored for older users, thrives when accessible and accepted, with the pivotal role of acceptance of change shaping its adoption. AimsThis study investigates the mediating role of acceptance of change in the relationship between gerontechnology acceptance and mental well-being among older adults and explores disparities in urban and rural settings Design & MethodsA cross-sectional, correlational design adhering to STROBE guidelines collected data through an interview survey from 802 older adults. Instruments included the Older Adult Structured Survey, Short Version of Senior Technology Acceptance, Acceptance of Change Scale, and the World Health Organization Well-Being Index. ResultsThe results underscore a significant correlation between technology adoption, adaptability, and mental well-being among 60-year-olds and older. Notably, an individual's openness to change significantly influences the technology-mental well-being relationship, emphasizing its impact on overall health. Urban areas exhibit a stronger positive correlation between technology acceptance and mental well-being, whereas rural regions demonstrate a more pronounced negative correlation. ConclusionThis research contributes valuable knowledge for addressing the unique challenges older adults face in diverse geographic settings, paving the way for targeted and effective initiatives. ImplicationsNurses should prioritize understanding the nexus between gerontechnology acceptance, change adaptability, and mental wellness, integrating technology education and culturally sensitive interventions to enhance care strategies for older adults in diverse geographic settings. This study lays the groundwork for developing person-centered geriatric nursing care plans, underscoring the importance of harnessing technology for improved mental well-being.
