Abstract
Background/Objectives: Mobile health applications are essential for improving healthcare access and promoting healthy lifestyles. This study investigates the roles of perceived ease of use, usefulness, and satisfaction in shaping behavioral intentions using the Technology Acceptance Model. Methods: A survey of 329 mobile health application users in Korea was analyzed using confirmatory factor analysis and structural equation modeling to test hypothesized relationships. Results: The findings indicate that perceived ease of use positively influences perceived usefulness (H1). Customer satisfaction is positively influenced by both the perceived ease of use and perceived usefulness (H2 and H3). Furthermore, behavioral intention is affected by perceived ease of use, perceived usefulness, and customer satisfaction (H4 through H6). Conclusions: The findings from this study elucidate how mobile health applications can enhance users' perceptions of ease of use and usefulness, thereby influencing their behavioral intentions through increased satisfaction. This research also advances our understanding of application services and informs the development of effective operational and marketing strategies.
