计算机自我效能感是一个经常被研究的结构，已被证明与一系列重要的个人结果有关。不幸的是，现有的计算机自我效能的措施遭受几个缺陷，包括标准污染，过时的措辞，和/或心理测量性能不足。因此，本文提出了一种新的计算机自我效能感测量方法。在研究1中，创建了一个过度代表性的项目列表，随后通过探索性因素分析减少，以创建一个初始措施，并测试了这个初始措施的判别效度。在研究2中，通过验证性因素分析支持了初始测量的单维度因素结构，并进一步减少到最终的12个项目的测量。在研究3中，12个项目的措施的收敛和效标效度进行了测试。总的来说，这三个研究过程表明，新的计算机自我效能感测量具有良好的心理测量特性和内部信度，并展示了良好的证据，在几个方面的效度。希望12项计算机自我效能感测量将在未来的研究中使用计算机自我效能感，这是目前的文章中讨论。
Computer self-efficacy is an often studied construct that has been shown to be related to an array of important individual outcomes. Unfortunately, existing measures of computer self-efficacy suffer from several deficiencies, including criterion contamination, outdated wording, and/or inadequate psychometric properties. For this reason, the current article presents the creation of a new computer self-efficacy measure. In Study 1, an over-representative item list is created and subsequently reduced through exploratory factor analysis to create an initial measure, and the discriminant validity of this initial measure is tested. In Study 2, the unidimensional factor structure of the initial measure is supported through confirmatory factor analysis and further reduced into a final, 12-item measure. In Study 3, the convergent and criterion validity of the 12-item measure is tested. Overall, this three study process demonstrates that the new computer self-efficacy measure has superb psychometric properties and internal reliability, and demonstrates excellent evidence for several aspects of validity. It is hoped that the 12-item computer self-efficacy measure will be utilized in future research on computer self-efficacy, which is discussed in the current article.
