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.
