Abstract: Objective To investigate the influence of 3 components in problem-based learning system, that is students, tutors and learning cases, on the critical thinking ability of undergraduate medical students. Methods A total of 114 medical students of grade 2013 in Peking University were involved in this study. The scores of student performance, tutor performance and case quality were collected after PBL teaching. The Chinese version of the critical thinking disposition inventory (CTDI-CV) was used to assess the critical thinking ability. Multiple linear regression analysis was used with the CTDI-CV scores as dependent variable, and the scores of student performance, tutor performance and case quality as independent variable. Correlation was analyzed between the 3 components in PBL system and the critical thinking ability. The analysis of numerical data was conducted by using SPSS 16.0. Results Critical thinking disposition of third-year undergraduate medical students in Peking University was at a positive level, the average total score was 303.5 and all subscale scores were over 40. Multiple linear regression analysis results showed 2 factors were of significance, that were students and case quality. Positive correlation was found between the scores of students and case quality with the scores of critical thinking ability, especially with the self-confidence subscale and the inquisitiveness subscale. Conclusions The performance of students and the case quality in PBL system are the key components which exert a significant influence on critical thinking ability and should be improved in medical education.
