Based on the technology acceptance model (TAM), we explored the nationally-bounded roles of four predictors (subjective norms, entertainment, recordability, and networkability) in determining the TAM variables of perceived usefulness (PU), perceived ease of use (PEOU), and behavioral intention (BI) to use diet/fitness apps on smartphones.
PARTICIPANTS/METHODS: College students in the US and South Korea were invited to participate in a survey. We obtained 508 questionnaires (304 from the US and 204 from Korea). Data were analyzed mainly through path analysis.
The four factors positively predicted the PU and PEOU of diet/fitness apps. While the effects of the predictors on the three TAM components were generally stronger among the US students than Korean students, the effect of subjective norms on the BI of diet/fitness apps was weaker among Korean students.
Findings from the cross-national comparisons were helpful for thoroughly understanding the contextualized mechanisms involved in the adoption of diet/fitness apps.
基于技术接受模型（TAM），我们探讨了四个预测因素（主观规范、娱乐性、可记录性和网络性）在确定使用智能手机上的饮食/健身应用程序的感知有用性（PU）、感知易用性（PEOU）和行为意向（BI）等TAM变量方面的国家边界作用。
参与者/方法：邀请美国和韩国的大学生参与一项调查。我们获得了508份问卷（美国304份，韩国204份）。数据主要通过路径分析进行分析。
这四个因素对饮食/健身应用程序的PU和PEOU有正向预测作用。虽然这些预测因素对三个TAM组件的影响在美国学生中总体上比韩国学生更强，但主观规范对韩国学生饮食/健身应用程序BI的影响较弱。
跨国比较的结果有助于深入理解采用饮食/健身应用程序所涉及的情境化机制。
