Clinical application of the copy task of the Rey-Osterrieth Complex Figure for patients with schizophrenia

Abstract

The purpose of this study was to clarify the characteristics of schizophrenia patients on a simple assessment scale for executive dysfunction using the copy task of the Rey-Osterrieth Complex Figure. We conducted an intergroup comparison of the performance of this assessment scale in a schizophrenia group and a healthy group, and investigated the relationship with other assessments. As a result, the performance of the schizophrenia group on this assessment scale was significantly lower than that of the healthy group. There was a significant moderate positive correlation between the performance of the schizophrenia group on this scale, multiple items on the Tower of London Test, and the occupational performance assessment sheet. It was thought that patients with schizophrenia may show a decline in performance on this assessment scale due to a decline in executive function. Furthermore, when using this assessment scale in clinical practice, it was confirmed that it is necessary to capture executive function in combination with other assessments.
