目的：探讨项目反应理论与计算机自适应测验(CAT)相结合的精神病学测量方法，以减轻研究和临床评估的负担。方法：数据来自800名因情绪或焦虑症而接受门诊治疗的参与者；他们分两次完成了626个条目的情绪和焦虑谱量表中的616个条目。第一次给药被用来通过使用后自组织模拟来设计和评估CAT版本的质量。第二项研究证实了CAT在活体检测中的作用。结果：基于项目反应理论的竞争模型检验支持量表的双因素结构，由一个主要维度和四个群体因素(情绪、惊恐-广场恐怖、强迫和社交恐怖)组成。模拟猫和活体猫均显示，与完全给药相比，给药(分别为24和30项)平均减少了95%(585项)。完整质量的分数和CAT版本的分数之间的相关性为0.93。对于情绪障碍子量表，两组抑郁症患者-一组有双相情感障碍，一组没有双相情感障碍-在满分和猫分上的得分差异显示出0.63(P
Objective: This study investigated the combination of item response theory and computerized adaptive testing ( CAT) for psychiatric measurement as a means of reducing the burden of research and clinical assessments. Methods: Data were from 800 participants in outpatient treatment for a mood or anxiety disorder; they completed 616 items of the 626- item Mood and Anxiety Spectrum Scales ( MASS) at two times. The first administration was used to design and evaluate a CAT version of the MASS by using post hoc simulation. The second confirmed the functioning of CAT in live testing. Results: Tests of competing models based on item response theory supported the scale's bifactor structure, consisting of a primary dimension and four group factors ( mood, panic- agoraphobia, obsessive- compulsive, and social phobia). Both simulated and live CAT showed a 95% average reduction ( 585 items) in items administered ( 24 and 30 items, respectively) compared with administration of the full MASS. The correlation between scores on the full MASS and the CAT version was .93. For the mood disorder subscale, differences in scores between two groups of depressed patients - one with bipolar disorder and one without - on the full scale and on the CAT showed effect sizes of .63 ( p
