Objective To revise the Reflective Functioning Questionary-8 (RFQ-8) and assess its reliability and validity in China. Methods Totals of 635 students who filled the RFQ-8，McLean Screening Instrument for Borderline Personality Disorder (MIS-BPD)，Toronto Alexithymia Scale (TAS-20) and FiveFacet Mindfulness Questionnaire (FFMQ) were selected as school group. 75 patients who visited Department of Psychiatry in Shengjing Hospital of China Medical University with borderline personality trait according to MIS-BPD were selected as clinical group and completed the RFQ-8. 47 students accepted the retest after three weeks randomly. Results The internal consistency for RFQ-C and RFQ-U were 0.673 and 0.514，while the test-retest reliability were 0.686 and 0.538，respectively. The correlations with TAS，FFMQ，MIS-BPD supported its validity. The score of RFQ-U was higher in clinical group，while the score of RFQ-C was higher in school group (P ＜0.01). The scores of RFQ-U and DFQ-C was negatively and positively correlated with education levels of parents respectively (P ＜0.01). Conclusions The revised RFQ-8 is applicable to assess the reflective function of adults in China with good reliability and validity. Future research should be done in Chinese clinical samples．
