人们在享受移动设备和服务的同时往往忽视信息保护，从而导致隐私泄露等信息安全问题。本研究整合保护动机理论和预期后悔理论，探讨驱动个人保护动机产生的认知和情绪要素。采用问卷调查法收集240份有效样本，并通过结构方程模型进行检验。结果表明隐私关注是保护动机产生的重要影响要素，担忧情绪部分中介隐私关注与保护动机之间的关系；而感知规避能力与保护动机之间的关系被预期后悔情绪完全中介。

 Individual users immerse themselves in experiencing mobile device and services but neglect the protection of personal information, which lead to information security issues such as privacy leakage. This paper integrates protection motivation theory and anticipated regret theory as the theory lenses to develop a research model to explore cognitive- and emotional-focused elements of driving personal information security protection motivation. 240 valid survey samples were collected and PLS-based structural equation modeling was adopted to test the research model and hypotheses. The findings indicate that privacy concern predicts positively protection motivation, and fear partial mediates the relationship between privacy concern and protection motivation while the significant path between perceived avoidability and protection motivation is completely mediated by anticipated regret.
