OBJECTIVE
We compared the pattern of cognitive deficits exhibited by people with schizophrenia at Allen Cognitive Level (ACL) 4 with that of people at Level 5.
METHOD
Participants were classified into two groups on the basis of their ACL Screen scores: ACL 4 (n = 35) and ACL 5 (n = 41). We assessed cognitive functions and psychotic symptoms in all participants.
RESULTS
Multivariate analysis of covariance controlling for gender and negative symptoms revealed that people at ACL 4 performed significantly worse than those at ACL 5 on processing speed, verbal memory, and working memory. The discriminant analysis with all cognitive variables produced a classification accuracy of 78% in differentiation of cognitive levels.
CONCLUSION
We verified the validity of the hierarchy of cognitive disability for ACLs 4 and 5 in people with schizophrenia.
目的
我们比较了认知障碍模式在艾伦认知水平（ACL）4 级和 5 级的精神分裂症患者中的表现。
方法
根据 ACL 筛查评分，参与者被分为两组：ACL 4 级（n=35）和 ACL 5 级（n=41）。我们评估了所有参与者的认知功能和精神病症状。
结果
多变量协方差分析控制性别和阴性症状显示，ACL 4 级的患者在处理速度、言语记忆和工作记忆方面的表现明显差于 ACL 5 级。使用所有认知变量的判别分析在区分认知水平方面产生了 78%的分类准确性。
结论
我们验证了 ACL 4 和 5 级的认知障碍分层在精神分裂症患者中的有效性。
