Abstract: This study aimed to develop a computerized adaptive testing (CAT) platform for assessing problematic mobile phone use (PMPU), implemented using the Java programming language. The platform integrated the Bayesian expected a posteriori method for latent trait estimation, the maximum Fisher information criterion for item selection, and a standard error threshold as the termination criterion. To evaluate the platform’s performance, a series of simulation studies were conducted by comparing the PMPU-CAT platform with both an R-based CAT implementation and the conventional paper and pencil PMPU assessment. The comparison focused on item usage, measurement error, and test reliability. The results indicate that the PMPU-CAT platform achieves high measurement precision while maintaining superior testing efficiency. Overall, the platform provides an effective technical tool for applications in educational and psychological assessment.

摘要: 本研究旨在开发一个基于JAVA语言的问题性手机使用的计算机化自适应测验平台。在平台开发过程中,采用贝叶斯期望后验估计作为能力估计的算法、最大信息量选题算法进行项目选择、标准误阈限值作为终止规则。通过模拟实验,将PMPU-CAT平台与R平台和问题性手机使用传统纸笔测验的题目使用数量、测量误差以及测验信度进行对比,结果表明,PMPU-CAT平台具有良好的测验精度,并且其测验效率较高。该平台可以为教育与心理测评领域提供良好的技术支持。
