In the paradigm of social cognition, social attribution and theory of mind provide individuals to understand and explain people’s behavior and intention. During these years, scholars tried to explain the formation of persecutory delusions by using social attribution and theory of mind. They suggested that patients with persecutory delusions tended to attribute negative events to external-personal causes and positive events to internal causes, which was likely an exaggerative self-serving bias. Kinderman, Dunbar, & Bentall(1998) suggested that abnormal attributions for patients with persecutory delusions is related to the deficits of theory-of mind, which caused patients unable to understand others’ intentions and mentality. Because of this, schizophrenic patients with persecutory delusion is considered to have attributional bias. However, only few researches were conducted in both abnormal attributions and deficits of theory-of-mind. As a resut, different methods and symptomatology used among theses researches lead to inconsistent and controversial point of view. Hence, this research will aim at investigating the abnormal attributional bias , deficits of theory-of-mind ,and their interaction of each other by apply differential courses to schizophrenic patients with persecutory delusion. Methods. A total of 29 Schizophrenic patients with persecutory delusion. The 15 patients were classified as acute persecutory delusion(APD), and 14 were classified as remitted persecutory delusion(RPD). They were assessed and compared by a translated (English to Chinese) attributional questionnaire (CIPSAQ) and task of theory-of-mind (2nd Order False Belief Task) with 15 healty controls. Results.The three groups show no significant differences in EB and PB. Patients with APD presented poor performance of 2nd Order False Belief Task than patients with RPD. The EB and poor performance of 2nd Order False Belief Task are significant relation to level of persecutory delusion. The interaction of attributional bias and deficits of theory-of-mind were not supported。 Conclusion. The results show the inconsistent findings with hypotheses. But when comparing to previous studies, there were consistent tendency to find. Patients with APD have more self-serving bia and more inability of theory-of-mind than patients with RPD. And Self-serving bias and deficit of theory-of-mind can be an index of persecutory delusion, respectively. In addition, the deficit of theory-of-mind related to higher external-personal attribution. Indicate that attributonal bias and theory-of-mind might still influence each other. Other factors that influence study and future implications were discussed.
