Can a person-fit method based on an item response theory differentiate clinical persons from a normal sample?

在MMPI临床量表8中，基于项目反应理论的个体拟合方法能够将精神分裂症患者与正常组区分开来，但在量表2中不能将抑郁症患者与正常组区分开来。结果表明，精神分裂症个体与正常群体之间是不连续的，而抑郁症个体与正常群体之间是连续的。此外，社会可取性对考试成绩的影响方式取决于个体对社会可取性的敏感性。

A person-fit method based on the item response theory in the clinical scale 8 on the MMPI was able to differentiate patients with schizophrenia from the normal group, but it on the scale 2 was not to differentiate patients with depression from normal. The results implies that the schizophrenia individuals are discontinuous from the normal group but the depress ones are continuous. Moreover, a way of influences of social desirability on test scores were dependent on the individual's sensitive to social desirability.
