Objective To conduct meta-analysis with the reliability of objective structured clinical examination (OSCE), so as to the reliability of OSCE used in the tests for evaluating clinical capacities of medical students. Methods Articles about evaluating clinical capacities of medical students using OSCE and using comprehensive coefficient of Cronbach's α to measure the reliability of OSCE were electronically searched in PubMed, ScienceDirect, CNKI, WanFang data and VIP from Jan. 1998 to May. 2013. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then meta-analysis was performed using SSPS 17.0 software. Results Thirty-four studies involving 53 coefficients of Cronbach's α were included, of which, there were 18 articles written in English involving 28 coefficients of Cronbach's α and 16 articles written in Chinese involving 25 coefficients of Cronbach's α. The results of meta-analysis showed that:the total coefficient of Cronbach's α of OSCE was 0.700 (95%CI 0.660 to 0.737). The coefficient of Cronbach's α of internationally-published literature was 0.745 (95%CI 0.696 to 0.790) and that of nationally-published literature was 0.648 (95%CI 0.584 to 0.705), with a significant difference between two groups. Conclusion Currently, the reliability of internationally/nationally-used OSCE is 0.7, which has relatively better reliability when used in the tests for evaluating clinical capacities of medical students at home and aboard. However, the reliability of OSCE at abroad is fairly better than that at home.
