The present article explores the concept of user involvement in the information system (IS) development context. It integrates situational involvement and intrinsic involvement constructs in the Technology Acceptance Model (TAM) and empirically tested a theoretical model with premises that were previously tested separately but not operationalized and tested together. From data collected from companies that have recently implemented an IS, Exploratory Factorial Analysis (EFA), Factorial Confirmatory Analysis (CFA), and Structural Equation Modeling (SEM) were used to assess the construct’s validity and the hypothesis test of the model, respectively. With a sample of 114 respondents, the main results indicate that situational involvement influences intrinsic involvement, perceived usefulness, and ease of use perception; it also indicates that intrinsic involvement influences usefulness perception, ease of use perception, and behavioral intention. Thus, this paper validated the assumptions about the importance of user involvement as an influence in adopting an IS, pointing out that situational involvement influences intrinsic involvement and that future users can become cognitively biased to better perceive a system as useful and easy to use, increasing its acceptance and adoption. It represents an original approach in this field with theoretical and empirical contributions.

本文探讨了用户参与信息系统 (IS) 开发环境中的概念。它在技术接受模型 (TAM) 中整合了情境参与和内在参与结构，并使用先前单独测试但未一起操作和测试的前提对理论模型进行了实证测试。从最近实施 IS 的公司收集的数据中，探索性因子分析 (EFA)、因子验证分析 (CFA) 和结构方程建模 (SEM) 分别用于评估构造的有效性和模型的假设检验。以 114 名受访者为样本，主要结果表明情境参与会影响内在参与、感知有用性和易用性感知；它还表明内在参与会影响有用性感知、易用性感知和行为意图。因此，本文验证了关于用户参与作为影响采用 IS 的重要性的假设，指出情境参与会影响内在参与，并且未来用户可能会在认知上有偏见以更好地认为系统有用且易于使用，从而增加它的接受和采纳。它代表了该领域的原创方法，具有理论和经验贡献。指出情境参与会影响内在参与，未来的用户可能会在认知上有偏见，以更好地认为系统有用且易于使用，从而增加其接受度和采用率。它代表了该领域的原创方法，具有理论和经验贡献。指出情境参与会影响内在参与，未来的用户可能会在认知上有偏见，以更好地认为系统有用且易于使用，从而增加其接受度和采用率。它代表了该领域的原创方法，具有理论和经验贡献。
