Information Technology Adoption Across Time: A Cross-Sectional Comparison of Pre-Adoption and Post-Adoption Beliefs

Abstract:The process of information technology adoption and use is critical to deriving the benefits of information technology. Yet from a conceptual standpoint, few empirical studies have made a distinction between individuals' pre-adoption and post-adoption (continued use) beliefs and attitudes. This distinction is crucial in understanding and managing this process over time. The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre-adoption and post-adoption beliefs and attitudes. The examination of Windows technology in a single organization indicates that users and potential adopters of information technology differ on their determinants of behavioral intention, attitude, and subjective norm. Potential adopter intention to adopt is solely determined by normative pressures, whereas user intention is solely determined by attitude. In addition, potential adopters base their attitude on a richer set of innovation characteristics than users. Whereas pre-adoption attitude is based on perceptions of usefulness, ease-of-use, result demonstrability, visibility, and trialability, post-adoption attitude is only based on instrumentality beliefs of usefulness and perceptions of image enhancements.

摘要:采用和使用信息技术的过程是实现信息技术惠益的关键。然而,从概念的角度来看,很少有实证研究区分个体收养前和收养后(继续使用)的信念和态度。随着时间的推移,这种区别对于理解和管理这一过程至关重要。本研究将创新扩散和态度理论结合在一个理论框架中,考察采用前和采用后的信念和态度的差异。对Windows技术在单个组织中的考察表明,信息技术的用户和潜在采用者在行为意图、态度和主观规范的决定因素上存在差异。潜在的采用者采用意向完全取决于规范压力,而用户意向则完全取决于态度。此外,潜在采用者的态度基于比用户更丰富的一系列创新特征。采纳前的态度基于对有用性、易用性、结果可证明性、可见性和可试验性的感知,而采用后的态度仅基于对有用性的工具性信念和对形象提升的感知。
