Objective: To translate and evaluate the validity and reliability the Self Reflection and Insight Scale (SRIS) in patients with mental disorders. Method: A sample of 363 subjects were selected, including 140 patients with schizophrenia, 92 patients with depression, and 131 healthy people. All of them were assessed for the project analysis and exploratory factor analysis. The criterion validity was tested with the Toronto Alexithymia Scale-20 (TAS-20). Totally 20 patients were retested for test-retest reliability with 2 week interval. Results: Two factors were established in the exploratory factor analysis. The total mutation rate was 48.87% and the load was 0.34 -0. 81. The scores of difficulty in external oriental thinking in TAS-20 were negatively correlated with the scores of self-reflection in SRIS respectively (ICC = -0. 31, P < 0. 01). The scores of difficulty in identity feelings, difficulty in describe feelings and external oriental thinking in TAS-20 were negatively correlated with the scores of insight in SRIS respectively (ICC = - 0. 66, - 0. 23, - 0. 21, P < 0. 05). Cronbach' s alpha coefficient of total scale was 0.83, and the Cronbach's alpha coefficients of subscales were between 0. 86 and 0.65. The test-retest reliability were 0. 80 for total scale, 0. 81 and 0. 61 for subscales. Conclusion: The validity and reliability of the translated questionnaire are satisfactory, which could be used in the measurement of patients' perception of meta-cognitive processes such as self-reflection and insight.
