Exploring behavioral factors and emotional mechanisms underlying older adult users' adoption of smart health services: evidence from PLS-SEM and fsQCA

The results show that perceived ease of use, perceived usefulness, and perceived emotion directly and positively influence behavioral intention. Mental interaction, self-actualization, and dynamic adaptation in emotional durable design exert indirect effects on behavioral intention through internalization processes. fsQCA identified 7 configurational paths leading to high behavioral intention, confirming the combined effects of "technology-emotion" factors, with no single factor constituting a necessary condition. This study contributes to expanding the emotional explanatory dimension of TAM, providing a theoretical foundation and practical guidelines for the human-centered design and promotion of SHS.
