The Chinese Version Of Internal,Personal And Situatiollal Attributions Questionnaire And The Correlation With R-fMRI Signal

Background:Social cognition refers to the cognitive processes involved in how people think about themselves, other people, social situations, and interactions. One important element of social cognition is attributional style (AS), which is defined as the ways in which one consistently explains events or the intentions of others. AS have important impact on peoples’mood and mental health. To study the relation of AS and psychosis diseases can help us to understand the psychological mechanism of the formation of the diseases. There were few instrument for investigate the AS of psychosis patients. So this study may have important clinical implications for investigating AS in Chinese patients with psychotic illness.Objectives:The purpose of this study is to examine the psychometric properties of the Chinese version of the Internal, Personal and Situational Attributions Questionnaire (C-IPSAQ). And we also investigate if patients with depression and patients with delusions exhibit attributional biases in China. We also want to find some resting fMRI evidence for these atttributional biases in deluded patients.Methods:The English language version of the IPSAQ was translated into Chinese for use in this study.200nonclinical individuals and47depression individuals completed IPSAQ, Beck Depression Inventory (BDI), and Attribution Style Questionnaire (ASQ). In addition,41schizophrenia patients with delusions completed the IPSAQ and BDI. Psychometric properties (various types of reliability and validity) were assessed for this translated questionnaire.21nonclinical individuals and23deluded patients were tested in resting state fMRI scan.Results:The C-IPSAQ was found to have good internal consistency as a scale. The mean Cronbach’s alpha of the six subscales was0.697(range from0.674to0.738). The corrected point-biserial item-total correlations and inter-rater reliability were both acceptable. The concurrent validity analysis found that the C-IPSAQ was significantly correlated with ASQ, suggesting that they are measuring the same psychological construct. The composite scores of the C-IPSAQ were also found to correlate with BDI scores. The group-comparison analyses showed differences in attributional style between patients with depression and patients with delusions compared to normal controls.Compared to normal controls, the deluded patients showed significantly decreased regional homogeneity in right occipital lobe. And in normal control group, the people with internal AS showed increased regional homogeneity in right occipital lobe compared to people with external-personal AS and external-situational AS.Conclusions:We confirmed the reliability and validity of the C-IPSAQ, We found that people with depression seem more likely to attribute negative events to internal causes; compared to normal controls, patients who experience delusions make less external-situational attributions for negative events; patients who are experiencing delusions make less external-situational but more external-personal attributions to negative events than patients with schizophrenia who are not experiencing delusions. Regional homogeneity of resting state brain activities in deluded patients was decreased in right occipital lobe. And the increased activities in this area may associate with the internal AS.
