用户信念和态度是驱动信息技术使用的关键看法。但是，随着用户获得使用的第一手经验，这些看法可能会随着时间而变化，这反过来又可能会改变其随后的IT使用行为。本文阐述了用户在IT使用过程中如何成为Liefs和态度的变化，定义了推动这种变化的新兴结构，并提出了信仰和态度变化的时间模型，通过利用期望证实证实理论以及现存的IT使用文献。来自两项最终用户计算（基于计算机的培训系统使用）和系统开发（快速应用程序开发软件使用）上下文的学生数据为假设模型提供了经验支持，证明了其在技术和用法环境中的普遍性，并使我们允许我们探测特定于上下文的差异。定性数据的内容分析验证了我们的一些定量结果。我们报告说，诸如脱节和满意之类的新兴因素对于理解IT用户的信念和态度的变化至关重要，并建议将其包括在IT使用的未来过程模型中。
User beliefs and attitudes are key perceptions driving information technology usage. These perceptions, however, may change with time as users gain first-hand experience with IT usage, which, in turn, may change their subsequent IT usage behavior. This paper elaborates how users' be liefs and attitudes change during the course of their IT usage, defines emergent constructs driving such change, and proposes a temporal model of belief and attitude change by drawing on expectation-disconfirmation theory and the extant IT usage literature. Student data from two longitudinal studies in end-user computing (computer-based training system usage) and system development (rapid application development software usage) contexts provided empirical support for the hypothesized model, demonstrated its generalizability across technologies and usage contexts, and allowed us to probe context-specific differences. Content analysis of qualitative data validated some of our quantitative results. We report that emergent factors such as disconfirmation and satisfaction are critical to understanding changes in IT users' beliefs and attitudes and recommend that they be included in future process models of IT usage.
