目的是从精神型人格障碍（SPD）的测量中获得更精确而丰富的信息，本研究首次采用了一种名为诊断分类模型（DCMS）的尖端心理测定理论（DC-SPQ）基于精神障碍的诊断和统计手册的第五版。 DCMS框架下的方法，招募了980名大学生来校准Schizotypal个性问卷的项目参数。在对其索引进行分析之前，将选择适合心理测量特征的项目组成DC-SPQ。结果表明，除了显示0.921的灵敏度和0.841的特异性外，DC-SPQ在经典测试理论和DCM上具有很高的可靠性和有效性，而在接收器操作特征曲线下的面积为0.841 = 0.936。同时，四因素模型提出了足够的数据与数据。更重要的是，DC-SPQ不仅提供了类似于传统问卷的通用信息，还提供了带有后验概率的症状级信息，该信息提供了对提供针对精神型人格障碍量身定制的个人特定干预措施的见解。 。结论本研究表明，DC-SPQ对于心理测定非常有价值，因为它可以阐明正在测量的症状并提供更合理的估计。
Objective To obtain more precise and rich information from the measurements for schizotypal personality disorder (SPD), a cutting-edge psychometric theory called diagnostic classification models (DCMs) was first employed in the present study to develop a diagnostic classification version of the Schizotypal Personality Questionnaire (DC-SPQ) based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Methods Under the framework of DCMs, 980 college students were recruited to calibrate item parameters of the Schizotypal Personality Questionnaire. Items that fit the psychometric characteristic would be selected to compose the DC-SPQ, prior to an analysis of its indexes. Results Results showed that the DC-SPQ had high reliability and validity in both the classical test theory and DCMs, in addition to showing a sensitivity of 0.921 and a specificity of 0.841 with area under receiver operating characteristic curve = 0.936. Meanwhile, the four-factor model proposed adequately fits with the data. More importantly, the DC-SPQ provides not only the general-level information similar to traditional questionnaires but also the symptom-level information with the posterior probability, which provides an insight into delivering the individual-specific intervention that is tailor made to schizotypal personality disorder. Conclusions This study demonstrates that the DC-SPQ is very valuable for psychometric detection in that it can clarify the symptom being measured and provide more reasonable estimates.
