초록

Objectives：Delusion is the key symptom that is observed among the patients with schizophrenia. The patients with schizophrenia with delusion symptom tend to have an early conclusion based on the unsatisfying data under the cognitively uncertain circumstances. Such reasoning bias is called as the “Jumping-to-conclusion”. Few studies have been made on the effect of “Jumping-to-conclusion” bias onto delusion in our nation. The present study aimed to review the presence of the reasoning bias of “Jumping-to-conclusion” in the patients with schizophrenia and to investigate the meaningful relationship of such “Jumping-to-conclusion” with patient symptoms and working memories of the patients with schizophrenia..
Methods：The patient group of the present study included 26 patients with schizophrenia who were hospitalized or treated as outpatients in the national bugok hospital. The diagnosis for the schizophrenia was made by 2 medical specialists in the psychiatric department based on the DSM-IV diagnosis criteria. As the normal control group, 25 nor-mal healthy subjects who could be comparable to the patient group in terms of gender, age, and education year were included. To all participants of the study, bead test and emotional card test were performed, and the computerized Wisconsin card sorting test that can measure the working memories of test subjects was also performed.
Results：Compared to the normal group, the schizophrenia patient group made an early conclusion in both of bead test and emotional card test. But the results did not show statistically significant relationship with the PANSS score and with the Wisconsin card sorting test.
Conclusion：The present study confirmed the presence of “Jumping-to-conclusion” bias in the patients with schizophrenia and proved that this bias is not related to psychiatric symptoms and to injuries of working memories.
