일반국민의 모바일 리터러시가 디지털 기기 이용 효능감에 미치는 영향 :디지털 조력과 삶의 만족도의 매개효과

This study aimed to examine the effect of mobile literacy on digital device use self-efficacy among the general population, investigating the complex mediating roles of digital assistance and life satisfaction. Utilizing data from 7,000 respondents in the 2024 Digital Divide Survey, a sequential double mediation analysis was conducted using PROCESS macro Model 6. The results revealed a paradoxical effect of mobile literacy: while it had a significant positive direct effect on digital device use self-efficacy, it negatively influenced both life satisfaction and the use of digital assistance. Furthermore, the sequential mediating path from mobile literacy through digital assistance and life satisfaction to digital device use self-efficacy was found to be statistically significant. These findings suggest that mobile literacy is a double-edged sword, enhancing technical confidence while simultaneously posing challenges to subjective well-being. This study underscores the need for digital inclusion policies to evolve beyond mere skill acquisition, focusing instead on fostering digital well-being and a critical understanding of the digital environment to ensure that enhanced capabilities translate into a genuine improvement in quality of life.
