The Mini-Mental State Examination (MMSE) and the Trail Making Test, part B (TMT-B) were compared for screening cognitive deficits in a sample of 104 psychiatric inpatients at a long-term hospital. The TMT-B classified 84% of the patients as impaired. The classic MMSE cutoff score (< or = 23) using serial sevens and spelling classified 42% and 24% of the patients respectively, as impaired. The new MMSE cutoff classified 71% as impaired. Education, gender, and medication may influence impairment when using the MMSE classic cutoff scores. In TMT-B only, impairment was influenced by chronicity. The TMT-B was able to distinguish patients impaired in the MMSE. The TMT-B, therefore, may be more useful than the MMSE to screen for cognitive deficits in chronic psychiatric inpatients.
在一家长期医院对104名精神科住院患者进行抽样，比较简易精神状态检查表（MMSE）和B部分连线测验（TMT-B）筛查认知缺陷的效果。TMT-B将84%的患者归类为受损。使用连续减法和拼写的经典MMSE临界值分数（≤23）分别将42%和24%的患者归类为受损。新的MMSE临界值将71%的患者归类为受损。在使用MMSE经典临界值分数时，教育程度、性别和药物治疗可能会影响损伤情况。仅在TMT-B中，损伤情况受病程影响。TMT-B能够区分MMSE受损的患者。因此，在筛查慢性精神科住院患者的认知缺陷方面，TMT-B可能比MMSE更有用。
