In multidimensional computerized adaptive testing (MCAT), item selection strategies are generally constructed based on responses, and they do not consider the response times required by items. This study constructed two new criteria (referred to as DT-inc and DT) for MCAT item selection by utilizing information from response times. The new designs maximize the amount of information per unit time. Furthermore, these two new designs were extended to the DT_S-inc and DT_S designs to efficiently estimate intentional abilities. Moreover, the EAP method for ability estimation was also equipped with response time. The performances of the response-time-based EAP (RT-based EAP) and the new designs were evaluated in simulation and empirical studies. The results showed that the RT-based EAP significantly improved the ability estimation precision compared with the EAP without using response time, and the new designs dramatically saved testing times for examinees with a small sacrifice of ability estimation precision and item pool usage.

在多维计算机化自适应测试中使用响应时间

在多维计算机自适应测试（MCAT）中，项目选择策略通常是基于响应构建的，并且不考虑项目所需的响应时间。本研究利用响应时间信息构建了 MCAT 项目选择的两个新标准（称为 DT-inc 和 DT）。新设计最大限度地提高了单位时间的信息量。此外，这两种新设计已扩展到 DT _S -inc 和 DT _S设计，以有效估计意图能力。此外，EAP能力评估方法还配备了响应时间。基于响应时间的 EAP（基于 RT 的 EAP）和新设计的性能在模拟和实证研究中进行了评估。结果表明，与不使用响应时间的EAP相比，基于RT的EAP显着提高了能力评估精度，并且新设计极大地节省了考生的测试时间，而能力评估精度和题库使用率的牺牲很小。
