Seventy-eight psychiatric in-patients were allocated to personal illness classes by means of the Delusions-Symptoms-States Inventory (DSSI). Paper and pencil measures of psychomotor speed and scatter of tapping were administered with an immediate retest. It is suggested that from a social desirability position one would have to predict that the more personally ill (i.e. those endorsing the more socially undesirable items) would be slower and more diffuse on these measures. We found, however, such patients to be more constricted and slower. It is concluded that such a combination adds to the utility and validity of the hierarchy of classes of personal illness.
78名精神科住院患者通过妄想-症状-状态量表（DSSI）被分配到个人疾病类别中。采用纸笔测试的方式对精神运动速度和敲击离散度进行测量，并立即进行重测。从社会期望的角度来看，可以预测病情越严重（即那些认可更多社会不良项目的患者）在这些测量中会更慢且更分散。然而，我们发现这类患者的表现更为受限且更慢。得出的结论是，这样的组合增加了个人疾病类别层次的实用性和有效性。
