双选项多维度强迫选择人格测量因其对反应偏差的容忍度而受到研究者的关注。此外，在用计算机进行人格测量时，反应时可以沿着项目反应一起收集。针对这种情况，本研究的目的是提出一个Thurstonian D-扩散项目反应理论（IRT）模型，该模型结合了两个主要的现有框架：用于测量强迫选择的Thurstonian IRT模型和用于测量人格反应时的D-扩散IRT模型。该模型反映了项目反应和反应时间数据生成机制背后的心理学理论。仿真研究表明，所提出的模型可以成功地恢复参数和因子结构在典型的应用设置。一个真实的数据应用表明，该模型估计类似，但仍然不同的参数值相比，原来的Thurstonian IRT模型，这种差异可以解释的反应时间信息。此外，该模型成功地反映了反应时间和潜在相对位置之间的距离-难度关系。
The two-alternative multidimensional forced-choice measurement of personality has attracted researchers' attention for its tolerance to response bias. Moreover, the response time can be collected along with the item response when personality measurement is conducted with computers. In view of this situation, the objective of this study is to propose a Thurstonian D-diffusion item response theory (IRT) model, which combines two key existing frameworks: the Thurstonian IRT model for forced-choice measurement and the D-diffusion IRT model for the response time in personality measurement. The proposed model reflects the psychological theories behind the data-generating mechanism of the item response and response time. A simulation study reveals that the proposed model can successfully recover the parameters and factor structure in typical application settings. A real data application reveals that the proposed model estimates similar but still different parameter values compared to the original Thurstonian IRT model, and this difference can be explained by the response time information. In addition, the proposed model successfully reflects the distance-difficulty relationship between the response time and the latent relative respondent position.
