This paper examines mobile device adoption by older adults in South Korea, one of the fastest ageing countries in Asia. It is important to understand how older adults perceive the use of mobile devices and the extent of their intention to continuously (or newly) use them. This paper includes personal innovativeness in the technology acceptance model (TAM) to better investigate mobile device use among older adults. The research model was empirically analysed using structural equations modelling (SEM). The results show that: 1) perceived ease of use (PEOU) and perceived usefulness (PU) partially mediate the relationship between personal innovativeness (PI) and behaviour intention (BI); 2) perceived ease of use (PEOU) has a stronger effect on behaviour intention (BI) than perceived usefulness (PU) does; 3) the use experience of mobile devices plays a moderating role in several paths of the proposed model; 4) invariance analysis reveals interesting and unexpected results.

个人创新对韩国老年人采用移动设备的影响：移动设备使用体验的适度效果

本文研究了亚洲老年人口速度最快的国家之一的韩国老年人对移动设备的采用情况。重要的是要了解老年人如何看待移动设备的使用以及他们持续（或新使用）移动设备的意图程度。本文将个人创新纳入技术接受模型（TAM）中，以更好地调查老年人中使用移动设备的情况。使用结构方程模型（SEM）对研究模型进行了经验分析。结果表明：1）感知的易用性（PEOU）和感知的有用性（PU）在一定程度上介导了个人创新（PI）与行为意图（BI）之间的关系；2）感知易用性（PEOU）对行为意图（BI）的影响要大于感知有用性（PU）；3）移动设备的使用经验在所建议模型的多个路径中起着适度的作用；4）不变性分析显示出有趣且出乎意料的结果。
