 as a neuropsychologic tool is recently used to assessment the cognitive functions. This study was aimed to determine the difference in performance of Institutionalized schizophrenic patients and normal subjects in drawing a clock test. To achieve the purpose 45 subjects who were diagnosed as chronic schizophrenic patients by psychiatrists in Isfahan psychiatry hospital, Isfahan, Iran were randomly selected. The normal subjects were selected among the families of patients and their mental health was confirmed after clinical interview (n=30). The schizophrenic group and normal subjects were assessed by CDT in two stages to determine the differences. The data was analyzed using ANOVA and χ2. The results of the study showed that there was significant difference between two groups in all the scores of CDT in two stages of test (first stage: F1, 73= 59.64, P<0.0001; and second stage: F1,73=121.82, P<0.0001). Also the frequency of errors in schizophrenic group was significantly more than the normal control. It is concluded that a two stages of CDT may used to find the abnormality of executive functions in schizophrenia.&picture=http://www.aascit.org/aascit/decorators/img/journal/906.jpg)

Clock drawing test (CDT) as a neuropsychologic tool is recently used to assessment the cognitive functions.

It is concluded that a two stages of CDT may used to find the abnormality of executive functions in schizophrenia.
