This study investigated the effect of computerized attention training on the improvement of cognitive functions in patients with schizophrenia. A total of 40 schizophrenic patients were randomly assigned to one of the three groups: the experimental(n=13), comparative(n=13) and control (n=14) groups. The attention training and Korean typing program were administered to the experimental and comparative groups, respectively. No training was given to the control group. The attention training consists of 10 sub-programs, which were developed to train sustained, selective and divided attention. Comprehensive neuropsychological tests such as the Rey-Osterrieth Complex Figure Test(ROCF), the Trail-Making Test, the Stroop test, the K-CVLT, the Wisconsin Card Sorting Test and the PANSS were administered before and after training. The three groups did not differ on the performances of any of the neuropsychological tests and for the PANSS scores administered prior to training. The experimental group showed significantly improved performances on the copy and delayed-recall conditions of the ROCF and the Stroop Color-Word Interference condition, which were administered after training, than did the comparative and control groups. In addition, the experimental group showed significantly reduced negative and general pathological symptoms after training, but the other two groups did not. These results indicate that attention rehabilitation training is effective for improving the cognitive functions of chronic schizophrenic patients. In addition, these results indicate the importance of cognitive rehabilitation for the treatment of schizophrenia.
