| Outline of Final Research Achievements |
The purposes of the study were to investigate factors to predict work outcome and to examine the accuracy of the perdition in patients with schizophrenia. The method to evaluate higher-order cognition was also studied to explore the effective variable(s) in the prediction. Logistic regression analysis showed that cognitive decline, psychiatric symptoms, and social function were significant variables to predict work status (work hours per week) in patients with schizophrenia. Overall, estimation was accurate yielding 70-80% accuracy. Singular value decomposition (SVD) analysis was applied to category fluency data to explore effective variable(s) of higher-order cognition to be used in predicting work outcome. The SVD analysis suggested that cosine value was the useful variable, revealing irregularity of the semantic memory organization in patients with schizophrenia.
