Test and retest scores on the Symptom Rating Test (SRT), Manifest Anxiety Scale (MAS) and Maudsley Personality Inventory (MPI) were obtained from 45 non-psychotic psychiatric in-patients. The change in scores and the score distributions were examined to assess the extent to which these tests meet Foulds' criteria for measures belonging respectively to the universes of personality and personal illness. MPI Extraversion emerged as a stable, normally distributed, personality trait in contrast to the SRT which showed the characteristics of a symptom-state measure. MPI Neuroticism and MAS scores could not be allocated definitively to either universe and seemed to be hybrids. It is suggested that more attention be paid to the 'purity' of scales if meaningful interpretation is to be made in treatment assessment.
我们从45名非精神病性住院精神科患者那里获取了症状评定测试（SRT）、显性焦虑量表（MAS）和莫兹利人格问卷（MPI）的测试及重测分数。对分数变化和分数分布进行了检查，以评估这些测试在多大程度上符合福尔兹分别针对属于人格和个人疾病范畴的测量标准。与显示出症状状态测量特征的SRT相比，MPI外向性表现为一种稳定的、呈正态分布的人格特质。MPI神经质和MAS分数不能明确地归入任何一个范畴，似乎是混合性的。建议如果要在治疗评估中进行有意义的解释，应更多地关注量表的“纯度”。
